Sodium and potassium benzoate are substances that may be added direcdy to human food and are affirmed as GRAS (33—35). Benzoic acid and sodium and potassium benzoate are now used as preservatives in such foods as sauces, pickles, cider, fruit juices, wine coolers, syrups and concentrates, mincemeat and other acidic pie fillings, margarine, egg powder, fish (as a brine dip component), botded carbonated beverages, and fruit preserves, jams, and jellies. The popularity of diet soft drinks has led to increased demand for both benzoate salts. 

These include mainly crystallised fruits, preserved fruits, jams, chocolates, sweetmeats, biscuits, effervescent citrate of magnesia, honey, condensed milk, liqueurs and sweet wines. Certain of these products are dealt with in other places, condensed milk, liqueurs and sweet wines, for instance, in the chapters dealing respectively with milk, spirits and liqueurs, and wines. The others are treated below, special attention being paid to the determination of the sugars. 

Jams or fruit preserves result from the boiling of fruit pulp with saccharose and often with glucose as well. Similar products are fruit jellies obtained from fruit juice instead of pulp and fruit syrups, made by mixing fruit juice with sugar syrup without boiling. With such materials the following determinations and tests are made. 

Lainson et al. (1980) contaminated a variety of food with T. cruzi suspensions pasteurized milk a mix of boiled beans, flaked fish, minced beef, and rice bottled mango juice mix of cheese and guava fruit preserve and dry mandioca flour. Batches of six mice were fed with each contaminated food. T. cruzi survived for at least 3 h, at 26-28 °C, in milk and in a mix of rice, beans, fish, and beef. All the 30 mice fed with the contaminated food became infected.

Polysaccharides from plants, too, can form gels in water. Pectin is used to help gel jams and fruit preserves. Some polysaccharides are used to thicken foods. Alginic acid, extracted from brown algae, is a linear polymer containing many carboxylic acid groups. The sodium salt is soluble in water and is used as a thickener in the preparation of ice cream and other foods. If a sodium alginate solution is mixed with calcium ion, the polysaccharide pre-... 

Multidimensional techniques are regularly used in analytical assessments of measurement data relating to the levels of chemical elements in the quality control of animal and plant food products. Chemometric interpretations have been obtained for the following animal products meat and meat products [316-318], fish [319-321], seafood [25, 322-328], milk and dairy products [329-332] and honey [333-339]. Similar interpretations have been obtained for the following plant products rice [143], cereals [340], vegetables [140, 341-346], fruit and fruit preserves [347], tea [155, 348-350], coffee [13, 155, 351, 352], mushrooms [26], fruit juices [141], confectionery [21, 353], nuts [354], wine [355-358], beer [66, 359] and other alcoholic beverages [159, 360, 361]. 

Before refrigeration became common, many foods were preserved by salting them heavily. Fruits were preserved by mixing them with a large amount of sugar (fruit preserves). How do salt and sugar act as preservatives ...

As a convenience, many manufacturers and distributors are packaging superfruits as frozen whole fruit or cut pieces. Analyses of nutritional contents show that frozen fruits preserve nutrients closely to those of fresh or dried fruits, so this is an acceptable format that may be more suitable to some people, especially those with limited access to fresh markets or out-of-season produce.

Naturally occurring organic acids, such as sorbic acid, benzoic acid, and acetic acid, are the most commonly used chemical preservatives in food and all have a broad antimicrobial spectrum (Plumridge et al., 2004). Benzoic acid, in particular, although mainly associated with fruit preservation, is used in many types of acidic food products (Suhr and Nielsen, 2004). Sorbic acid inhibits both molds and yeasts, and is used in a broad variety of food products (Sofos and Busta, 1981), including fine bakery products, confectionery, and bread (Suhr and Nielsen, 2004). 

Strawberry preserves represent about 26% of all fruit preserve flavors, or about 12% of the total production of all fruit spreads, and consequently the largest volume of a single variety of fruit spread in the country. 

The dehydration technique, which slowly dries fruit by extracting all the moisture, enables fruits to be stored without deteriorating, and is one of the healthiest forms of fruit preservation. If you grow your own fruit, you may prefer to buy a dehydrator. Whether rehydrated or used as they are, dried fruits make an excellent snack food. 

What is osmotic pressure How is osmotic pressure calculated Molarity units are used in the osmotic pressure equation. When does the molarity of a solution approximately equal the molality of the solution Before refrigeration was common, many foods were preserved by salting them heavily, and many fruits were preserved by mixing them with a large amount of sugar (fruit preserves). How do salt and sugar act as preservatives Two applications of osmotic pressure are dialysis and desalination. Explain these two processes. 

Tamarind flour is used as food thickeners, stabilizers, and gelling agents. Polysaccharides from tamarind seeds can be used to replace pectin in the manufacture of jellies and jams, can be used in fruit preserving with or without acids, and can be used as a stabilizer in ice cream, mayonnaise, and cheese.
