19.3.6.01 Water content
Food is commonly preserved by decreasing the availability of water in the food to micro-organisms, i.e. by decreasing the water activity. The water activity of pure water = 1, so any dissolved substances reduces the water activity. You can measure the water activity measuring the equilibrium vapour pressure of the water or by measuring its freezing point or boiling point) So water activity can be decreased by drying processes or by adding solutes, e.g. sodium chloride, sugar, sodium nitrate. Lowering of pH also controls micro-organisms.
19.3.6.02 Nutritional value
The nutritional value of a processed food is rarely better than that of the raw ingredients from which it is produced, unless nutrients are added in purified or concentrated form. Some beneficial effects of processing include the destruction of trypsin inhibitor in legumes, and the liberation of bound niacin in cereals. The consumer can judge reduction in nutritional value of food because it is usually accompanied by a reduction in colour, flavour and texture.
19.3.6.03 Lost nutrients
Nutrients may be lost during food processing because they react with other constituents of the food, oxygen, light or heat, or because they are leached by water. Trace elements and enzymes may also catalyse the destruction of the nutrients. Nutrient loss varies with the type of food, the length of time of processing and the particular nutrient. Nutrients that are unstable in solution include vitamin A, vitamin C, vitamin D, folic acid, vitamin K, riboflavin, thiamine and essential amino acids threonine and tryptophan. Nutrients that are unstable cooking heat include vitamin A, vitamin C, biotin, vitamin D, folic acid, vitamin K, riboflavin, thiamine and essential amino acids lysine, threonine and tryptophan. Canned meats contain less thiamine than fresh cooked meats because some is destroyed by the heat sterilization. The importance of nutrient losses during processing depends on the total diet. Where essential dietary components are in limited supply, any loss of nutrients may be important.
19.3.6.04 Blanching
Blanching, plunging vegetables in boiling water for 2 minutes, inactivates enzymes. Potatoes cut for potato chips, French fries, boiled for two minutes and then cooled in a refrigerator for a further two minutes do not brown as fast as potatoes that are only cut before cooking. During preservation by canning, freezing or dehydration, most vegetables are blanched by immersion in steam or hot water. Blanching inactivates enzymes that otherwise would cause deterioration of the food during storage and subsequent thawing. Steam blanching results in greater retention of water-soluble nutrients than water blanching. Microwave blanching results in better ascorbic acid retention in Brussels sprout. Vegetables that have significant loss of vitamin c and thiamine from blanching include spinach, broccoli, green beans, lima beans, Brussels sprout, cauliflower and peas.
19.3.6.05 Vitamins
Percentage retention of vitamins in canned foods at 27oC for 12 months are as follows:
1. Peas: Vitamin C 86%, thiamine 74%, carotene 91%,
2. Orange juice: Vitamin C 77%, thiamine 89%,
3. Tomatoes: Vitamin C 82%, thiamine 82%.
19.3.6.06 Freezing, thawing and cold storage
Percentage loss of nutrients from muscle meats and liver:
1. Frozen storage for 3 months to 20%-40% thiamine, 0%-30% riboflavin, 18% niacin and pantothenic acid.
2. Refrigerator storage for two weeks - 8%-10% thiamine and pantothenic acid, 10%-15% riboflavin, <10% niacin. Thawing in running water loses thiamine and pantothenic acid and up to 33% pantothenic acid is lost in the "drip" from thawed beef.
19.3.6.07 Thermal processing, cooking and canning
Pyridoxine (vitamin B6), folic acid and pantothenic acid are the most vulnerable of the B vitamins in foods of animal origin. From 50% to 90% of folic acid and pyridoxine, and 10% to 50% of pantothenic acid may be lost during cooking.
19.3.6.08 Freezing, thawing and cold storage
Freezing, thawing and cold storage, percentage loss of nutrients from muscle meats and liver:
1. Frozen storage for 3 months to 20%-40% thiamine, 0%-30% riboflavin, 18% niacin and pantothenic acid.
2. Refrigerator storage for two weeks to 8%-10% thiamine and pantothenic acid, 10%-15% riboflavin, <10% niacin. Thawing in running water loses thiamine and pantothenic acid and up to 33% pantothenic acid is lost in the "drip" from thawed beef.
19.3.6.09 Thermal processing, cooking and canning
Thermal processing, cooking and canning to Pyridoxine (vitamin B6), folic acid and pantothenic acid are the most vulnerable of the B vitamins in foods of animal origin. From 50% to 90% of folic acid and pyridoxine, and 10% to 50% of pantothenic acid may be lost during cooking.
19.3.6.10 Preservatives or antimicrobials
Benzoic acid and its sodium salts are bacteriostatic or germicidal agents. Many berries, e.g. raspberries, contain up to 0.05% benzoic acid. It may be included in foods of pH < 4.5, e.g. soft drinks, to inhibit the growth of bacteria. The body excretes benzoic acid as hippuric acid.
Sulfur dioxide and sulfites (E220-224) inhibit deterioration of dried fruits and fruit juices. In the fermentation industry it is used to prevent spoilage by microbes, as a selective inhibitor, as an antioxidant and antibrowning agent. Sulfur dioxide destroys thiamine so it is only allowed in to foods not an important sources of thiamine. It may be not allowed in meat, except for cooked manufactured meat, e.g. salamis, sausages. Some people are allergic to sulfur dioxide.
Propionates, CH3CH2COOH (E280-283), e.g. calcium and sodium salts of propionic acid, are used in bread (0.2%) to inhibit the growth of micro-organisms, e.g. Bacillus subtilis which causes "rope" that makes bread inedible.
Sorbic acid (E200-203) (2,4-hexadienoic acid, CH3-CH=CH-CH=CHCOOH occurs in some fruits and inhibits some moulds, yeasts, and bacteria in cheese, pickles, fish products, cordials, and carbonated drinks.
19.3.6.11 Microbial contamination
Aflatoxin is a naturally occurring toxic products found in moulds in foods, especially peanuts (ground nuts) and peanut butter, due to lack of proper drying and storage of crops.
19.3.6.12 Pasteurization
Pasteurization of milk destroys all pathogenic organisms and most other bacteria to reducing the risk of milk-borne infection. However, there is some loss of thiamine (vitamin B), and ascorbic acid (vitamin C). The amounts of nutrients lost from a processed food depend on the temperature experienced, the time that elapses between processing and consumption, the nature of the food and sometimes the nature of the container.
During pasteurization of milk the minerals, vitamin A, vitamin D, pyridoxine, niacin, pantothenic acid and biotin not affected. Riboflavin, vitamin E and vitamin K are only slightly affected. Thiamine is reduced by 3%. The proteins albumin and globulin may be 10% coagulated. Vitamin B1 and vitamin C may be greatly affected, but milk is not an important source of these vitamins.
19.3.6.13 Nutrients in food
1. Minimize the amount of chopping and cutting of vegetables for cooking by boiling.
2. Do not use sodium bicarbonate, sodium hydrogen carbonate, in cooking to make cooked vegetables look greener as it increases the rate of loss of thiamine and vitamin C.
3. Store foods at the lowest appropriate temperature and for the shortest possible time. Avoid storing cooked foods for lengthy periods in the freezer or refrigerator. When you buy frozen food, carry it home in an insulated container and place it in the home freezer as soon as you get home.
19.3.6.14 Bacteria in food
Hot food stored in a restaurant should be always above 60oC. Cold food stored in a restaurant should always be below 5oC. However, many foods kept on display, e.g. pies or sushi, are not kept at these temperatures, in which case bacteria can multiply in them. To control bacteria, temperatures should either be very high or very low:
115oC to 120oC: Canning temperatures used for low acid vegetables, meat, and poultry in pressure canner.
100oC to 115oC: Canning temperatures used for fruits, tomatoes, and pickles in water bath canner.
75oC to 100oC: Cooking temperatures that destroy most bacteria. The time required to kill bacteria decreases as temperature is increased.
60oC to 75oC: These warming temperatures prevent growth but allow survival of some bacteria.
40oC to 60oC: At these temperatures some bacterial growth may occur and many bacteria survive.
15oC to 40oC: These temperatures allow rapid growth of bacteria and production of toxins by some bacteria.
5oC to 15oC: At these temperatures some growth of food poisoning bacteria may occur. Do not store meats, poultry, or seafood for more than a week in the refrigerator.
0oC to 5oC: These cold temperatures permit slow growth of some bacteria that cause spoilage.
-10oC to 0oC: These freezing temperatures stop growth of bacteria, but may allow bacteria to survive.
19.3.6.15 Metal soft drink-cans to store non-alcoholic drinks
Cut the tops off two aluminium soft drink-cans. Fill one can with a sodium bicarbonate solution and fill the other with a vinegar solution. After 3 days observe corrosion in the can containing sodium bicarbonate but not in the can containing vinegar. The aluminium oxide formed on the surface of the aluminium can is stable in acid solutions but dissolves in the basic solution leaving the aluminium unprotected. So aluminium cans are used to store low pH fruit drinks.
Repeat the experiment with tin-coated steel cans (not protected with a protective lacquer coating.)
19.4.2.2 Food allergies and intolerances
Some people can be sensitive to the effects of natural food chemicals. Although the body becomes accustomed to small amounts of these substances in the daily diet, eating too much of certain foods or a sudden change of diet or infection, can alter the body's reaction. The tastier a food is, the richer it is likely to be in natural chemicals, e.g. chocolate and mint. Small amounts of natural chemicals present in a food, e.g. chocolate, may not be enough to cause a reaction by itself. However, the chocolate may cause a reaction because a chemical may be common to many different foods so a reaction occurs when the threshold is finally exceeded by eating the chocolate. Organic foods may contain fewer traces of pesticides and other agricultural chemicals, but they contain the same natural pesticides and preservatives in the skin.
Food additives: People who are sensitive to natural food chemicals are usually also sensitive to food additives, e.g. preservatives to keep foods fresh and colourings to make foods look more attractive. If you need to avoid these additives, check the labels.
Food intolerance: Reactions to food chemicals are called intolerances. They irritate different parts of the body causing headaches, mouth ulcers, stomach pains and bowel irritation. Children may become "hyperactive" after eating a rich meal or coloured, flavoured and preserved foods or drinks. In sensitive people, natural chemicals may build up to cause recurrent symptoms. They should avoid spicy foods and processed foods.
Food allergy: A food allergy is caused by antibodies to food proteins from particular foods, e.g. milk, eggs, wheat, peanuts or fish. A food allergy may cause itching mouth, vomiting and cramps. People sensitive to natural food chemicals are usually also sensitive to one or more of the common food additives.
Oils: Margarine and oils may be preserved to stop them going rancid but cold pressed oils are not preserved, e.g. cold pressed coconut oil. Sunflower and safflower oils sometimes contain antioxidants. Margarine is sometimes preserved fat reduced ("light"). Spreads are usually preserved. Heavily flavoured fats and oils, e.g. olive oil, corn oil, peanut oil, sesame oil, walnut oil, almond oil, Copha, all contain moderate to high levels of natural chemicals. Cow or goat milk, cream and butter are all very low in natural chemical content
Starches: Refined rice products and wheaten cornflour are the lowest in natural chemicals, though some people prefer whole grain and wholemeal products Potato products may contain preservatives (220-228), or antioxidants if cooked in oil.
Sugars: Refined sugar in moderation usually causes no adverse effects. Avoid all sweets with colours and flavours other than vanilla. Most dried fruits are preserved with sulfite that may cause asthma attacks. Sun-dried fruits without preservative have a very high natural chemical content.
19.4.2.2.1 Salicylate intolerance
Salicylates are used in medicine for painkilling, anti-inflammatory action and as preservatives in processed foods. Salicylates include salicylic acid and sodium salicylates. Salicylates usually do not cause harm to healthy adults but aspirin may be harmful to children and to elderly people. Other salicylate painkillers include extract of the bark of the willow tree (Salix alba vulgaris) and oil from meadow sweet (Spirea ulmaria). Other naturally occurring salicylates are in many fruits and vegetables in very small amounts. Aspirin, analgesic, acetylsalicyclic acid (2-acetyloxybenzoic acid), is made in factories from salicylic acid, HOC6H4COOH, 1-hydroxybenzoic acid. Methyl salicylate, oil of wintergreen (Gaultheria procumbens) used as a liniment for sore muscles. Phenyl salicylates (salol) are used in sunscreens and as a stabilizer in plastics. Salicylanilide, a compound of salicylic acid and aniline derivatives, is used as an antiseptic in soap. Most fruits and many vegetables contain natural salicylates, and some also have high amine levels. Salicylates have a natural preservative action and are concentrated near any surface of fruits and vegetables. Levels of salicylates are higher in unripe fruits and decrease with ripening. In many cases these natural chemicals are concentrated near the skin and you can avoid them by peeling, e.g. potatoes and pears. Natural chemical content also varies with ripeness. Salicylates are highest in unripe fruit, and decrease with ripening. Flavoured or fruit yoghurt may also contain salicylates. Spicy processed meats can also contain salicylates or MSG, e.g. salami, seasoned meats, meat pies, sausages and sausage rolls, frankfurters, meat pastes and extracts.
19.4.2.2.2 Amine intolerance
Amines come from protein break down or fermentation. Large amounts are present in cheese, chocolate, wines, beer, yeast extracts and fish products. They are also found in certain fruits and vegetables, e.g. bananas, avocados, tomatoes and broad beans. You also make tiny amounts of some amines in your own body, e.g. adrenaline. Amines increase with ripening in fruits that go soft, e.g. banana and avocado. Highly sensitive people should wash fruits and vegetables thoroughly before eating, thickly peel pears and potatoes and discard the outer leaves of lettuce. Yoghurt may have some amines. Cheeses contain varying amounts of natural amines and MSG. The tastier the cheese, the higher its chemical content is likely to be. Soy milk and fresh products like tofu and tofu ice cream all have a low natural chemical content and so usually causes no chemical intolerance problems unless the person is allergic to soy bean proteins. However, fermented products like soy sauce, tempeh and miso are rich in natural amines and MSG. Browning meat, grilling or charring will increase natural amine levels which make them more tasty. Fresh meats, poultry, seafood, and eggs are all low in natural chemicals. However, amines can form as a result of a protein break down in aged, overcooked and processed meats. Pork, chicken skin, canned or frozen fish, liver, kidney and other offal contain high amine levels. Buy and eat meat within two days. Processed meats are rich in amines, and may be preserved with nitrites, e.g. ham, bacon, corned beef. Fish products, especially those which are salted, smoked, pickled or dried, are rich in amines and other natural chemicals.
19.4.2.2.3 Monosodium glutamate intolerance
See diagram 16.3.6.0 (5.): Monosodium glutamate
MSG, monosodium glutamate, sodium hydrogen glutamate, is the monosodium salt of glutamic acid, a natural amino acid. and a building block of all proteins. It is found naturally in most foods. It is used as an additive to increase the flavour of soups, sauces, Asian cooking and snack foods. Umami is the taste of monosodium glutamate. Excess MSG, often in Asian soup liquids, causes unpleasant "wooden tongue" feelings. MSG is banned in prepared baby food. It is produced by fermentation of sugars produced by acid hydrolysis of molasses or tapioca using the bacterium Corynebacterium glutanicum. However, the MSG used to prepare cheap street foods may be adulterated.
19.4.2.2.4 Lactose intolerance
Lactose intolerance is a problem for people who cannot tolerate lactose (milk sugar). Refined sugar in moderation usually causes no adverse effects.
19.4.2.2.5 Gluten intolerance
Wheat may be a problem for people who cannot tolerate gluten. Coeliac disease is an allergy to gluten. Bread making flour may be preserved with sulfite but most disappears during cooking.
19.4.2.3.0 Caffeine, extraction by supercritical carbon dioxide, critical point
Materials can exist in three states: solid, liquid and gas. You can change from one to another by altering temperature and / or pressure. If you increase temperature and pressure enough, the distinction between liquid and gas will disappear at the critical point. No phase boundary between liquid and gas exists because at extremely high temperatures and pressures, the liquid and gaseous phases become indistinguishable. The critical point of water is 374°C 218 atmospheres of pressure. At above 31.1oC and 72.9 atmospheres of pressure carbon dioxide behaves like liquid and like a gas. It spreads out like a gas to fill the available space and can dissolve substances as if it was a liquid. The low temperature is convenient because it can be used with substances that would be damaged by the high temperature. Supercritical carbon dioxide is used to remove caffeine from tea and coffee, an extract substances from hops, essential oils, and environmental pollutants. It is also used for dry cleaning. Supercritical carbon dioxide is used to extract caffeine from coffee beans, extract nicotine from tobacco, extract oil from oilseeds, e.g. soy bean and sunflower, extract the natural insecticide pyrethrin.
19.4.2.3.1 Approximate caffeine content of beverages
Percolated coffee cup 150 mL, Caffeine content 100 mg
Drip coffee cup 150 mL, Caffeine content 80-200 mg
Instant coffee cup 150 mL, Caffeine content 60-70 mg
Cocoa cup 150 mL, Caffeine content 5 mg
Chocolate bar 100 g Caffeine content 20 mg
Cola drink-can 375 mL, Caffeine content 35-55 mg
Tea cup 150 mL, Caffeine content 50 mg
Decaffeinated tea cup 150 mL, Caffeine content 2 mg
Coffee beans (green) Caffeine content 0.8-1.8% mg
Tea leaves (undried) Caffeine content 0.8-2.1% mg
In some countries, the legal limit for caffeine content is 55 mg / 375 mL (cola drink-can)
The fatal dose of caffeine is about 10 mg.
Caffeine is used in analgesic preparations containing ergotamine for the relief of migraine headaches. Caffeine is found in coffee Coffea arabica, tea Camellia sinensis, yerba mate Ilex paraguariensis, guarana Paullinia cupana, cola Cola nitida. Theobromine is found in chocolate Theobroba cacao.
19.4.2.4 Relative sweetness of some artificial sweeteners
Relative sweetness, mass for mass, is measured by comparing the taste in water to a 4% solution of cane sugar.
Sucrose, cane sugar, food, Relative sweetness 1.0
Lead acetate, sugar of lead, TOXIC, Relative sweetness 1.0
Glycerol, glycerine, E 422, Relative sweetness 0.6
Ethylene glycol, anti-freeze, TOXIC, Relative sweetness 1.3
D-tryptophan, amino acid, Relative sweetness 35

Acesulfame-K, E 950, Relative sweetness 150
Aspartame, dipeptide ester, E 951, Relative sweetness 160, e.g. "Equal",
Dulcin, sucrol, 4-ethoxyphenyl urea (not allowed most countries), relative sweetness 250
Saccharin, o-toluene sulfonamide, E 954, Relative sweetness 300-500, e.g. "Sweet 'N Low"
Sucralose, trichlorogalactosucrose, E 955, Relative sweetness 650, "Splenda, No Calorie Sweetener"
Alitame, dipeptide amide, E 956, Relative sweetness 2000
Thaumatin, West African plant Ketemfe (Thaumatococcus danielli) E 957, Relative sweetness 750-1600
The sugar derivative, sucrose octoacetate, is bitter and is used as a harmless denaturant for alcohol to make denatured spirit undrinkable. Previously, denatured spirit contained methanol to make it undrinkable but it caused blindness in alcoholics determined to drink it.
19.4.2.5 Sweeteners phenylalanine and aspartame
1. Phenylalanine has the systematic name: (S)-2-Amino-3-phenyl- propanoic acid, chemical formula C9H11NO2, C6H5CH2CH(NH2)COOH. So phenylalanine is classed as a phenylketonic. The alpha- amino acid phenylalanine exists in two forms, the D-forms and L-forms, which are enantiomers, mirror image molecules, of each other. L-phenylalanine (LPA) is an electrically neutral amino acid, one of the twenty common amino acids used to biochemically form proteins, coded for by DNA. Its enantiomer, D-phenylalanine (DPA), can be synthesized artificially. L-phenylalanine is used in living organisms, including the human body, where it is an essential amino acid. The synthesized mix DL-phenylalanine (DLPA), which is a combination of the D-forms and L-forms, is used as a nutritional supplement. Some authorities suggest that the amino acid DL-phenylalanine should be used with caution if you are pregnant or diabetic, if you have high blood pressure or suffer anxiety attacks. Phenylalanine is part of the composition of aspartame, a common sweetener found in prepared foods (particularly soft drinks, and gum). Phenylketonuria (PKU) is an inherited human genetic disorder of people without the ability to metabolize phenylalanine that occurs in about 1 in 15,000 births, but 1 in 4,500 births among the Irish. Due to phenylketonuria, products containing aspartame usually have a warning label that they contain phenylalanine, in compliance with USA FDA guidelines. Phenylalanine, a natural amino acid found in many foods, is deleterious only to sufferers of the genetic disorder phenylketonuria.
2. Aspartame is the name for the artificial, non-carbohydrate sweetener, Aspartyl-phenylalanine-1-methyl ester, i.e. the methyl ester of the dipeptide of the amino acids aspartic acid and phenylalanine D-forms and L-forms, which are enantiomers (mirror image molecules) of each other. Aspartic acid, 2-aminobutanedioic acid, HOOCCH2CH(NH2)COOH, also called aspartate, the name of its anion, is one of the 20 natural proteinogenic amino acids which are the building blocks of proteins. The amount of aspartame in an average can of diet cola is about 0.06%. Aspartame is 160 times sweeter than sugar, sucrose with E number (additive code) E951. It is a common sweetener in prepared foods, particularly soft drinks. Aspartame is one of the sugar substitutes used by diabetics. Products containing aspartame usually have a warning label that they contain phenylalanine, in compliance with U.S. FDA guidelines. Aspartame breaks down into its constituent amino acids when heated in the presence of water and acids. So it is unsuitable for use in baking but is commonly used in diet soft drinks or to sweeten coffee and tea. A soft drink is a drink that contains no alcohol. While aspartame, like other peptides, has a caloric value of 4 kilocalories per gram, the quantity of aspartame needed to produce a sweet taste is so small as to make its caloric contribution negligible, which makes it a popular sweetener for those trying to avoid calories from sugar. Some authorities suggest that aspartame is a risky chemical food additive, and its use during pregnancy and by children is one of the greatest modern tragedies in human history. Aspartame is synthesized from the two amino acids L-aspartic acid and L-phenylalanine, which are bonded by methanol. Aspartame breaks down easily and loses its sweetness when heated Toxic levels of aspartame in the blood may result in mental retardation, altered brain function and behaviour changes in humans and cause side effects including dizziness, headaches and menstrual problems. Since the FDA approved aspartame for consumption in 1981, some researchers have suggested that a rise in brain tumour rates in the United States may be at least partially related to the increasing availability and consumption of aspartame and phenylalanine.

19.4.4.5 Food additives and EEC code numbers
E-numbers indicate approved as food additive in some countries but this list may not be current in your country. Descriptors from previous lists shown in brackets. An additive is a substance added to food to modify flavour, colour, texture, keeping properties or nutritional content. It is illegal to add additives to food unless permitted by law. Minerals and vitamins added to food to improve the diet do not need additive numbers unless added for another purpose, e.g. as an antioxidant.
19.4.4.6 Sequestrant food additives
See also 16.4.4: EDTA
They are added to food to form tightly bound complexes with unwanted metals to prevent the decomposition of the food. The sodium and calcium salts of EDTA (ethylene diaminetetra acetic acid) are common sequestrants.
19.4.4.7 Humectant food additives are moisturizers that attracting water, e.g. sorbitol for skin products and glycerine for shampoos.
