In food preparation

Lithium Hypochlorite. Lithium hypochlorite [13840-33-0], LiOCl, is obtained from reaction of chlorine and an aqueous solution of lithium hydroxide. The soHd is usually obtained as a dry stable product containing other alkaH haHdes and sulfates (64). A product containing 35% available chlorine is used for sanitizing appHcations in swimming pools and in food preparation areas where its rapid and complete dissolution is important. The salt can also be obtained in higher purity by reaction of lithium hydroxide and hypochlorous acid (65). 

Molybdenum improves the corrosion resistance of stainless steels that are alloyed with 17—29% chromium. The addition of 1—4% molybdenum results in high resistance to pitting in corrosive environments, such as those found in pulp (qv) and paper (qv) processing (33), as weU as in food preparation, petrochemical, and poUution control systems. 

In deciding whether disulfiram should be used in alcoholism rehabilitation, patients should be made aware of the hazards of the medication, including the need to avoid over-the-counter preparations that include alcohol, the need to avoid drugs that can interact with disulfiram, and the potential for a DER to be precipitated by alcohol used in food preparation. The administration of disulfiram to anyone who does not agree to use it, who does not seek to be abstinent from alcohol, or who has any psychological or medical contraindications is not recommended. 

Additionally, organotin-catalysed silicones have been used in products such as coatings on baking paper (for use in food preparation), and this use is considered in more detail in the consumer exposure assessment (section 6). Information provided by the Centre Europeen des Silicones (CES, 2002b) indicated that organotin-catalysed silicones are used in only a small proportion of baking paper produced in the EU ... 

Although Colorado relies on standard contamination laws, the city and county of Denver specifically limit the use of residual sprays to those conditions in which foodstuffs, utensils, and equipment are covered and protected. Misting sprays may not be used in food preparation areas but are permitted in dining rooms of eating establishments. 

Lead-containing ceramic ware used in food preparation has also been associated with childhood lead exposure in children of Hispanic ethnicity in San Diego County, California. One study (Gersberg et al. 1997) used the IEUBK to determine that dietary lead exposure from beans prepared in Mexican ceramic bean pots may account for a major fraction of blood lead burden in children whose families use such ceramic ware. 

Finally, passing mention must be made of the two most important organic pigments in our world, both natural products. These are chlorophyll and haemoglobin, which are absolutely vital in the strict meaning of the word, but only chlorophyll has found a commercial use as a colorant in food preparation. 

Vinegar (a solution of aoetio aoid) is a sour tasting liquid used in food preparations, partioularly in salad dressings and piokling prooesses. 

Maiilard Reaction. In amino acids, the amino group tends to form condensation products with aldehydes. This reaction is regarded as the cause of the browning reaction when an amino acid and a sugar coexist. A characteristic flavor, useful in food preparations, is evolved along with the color in this reaction,... 

Heat-generated flavors, due to the formation of lactones and methyl ketones from hydroxy and keto add precursors, which occur in trace quantities in milk lai. These flavors arc considered to be desirable in fried and baked goods and are partly responsible for the unique condiment properties of butler in food preparation. However, they are undesirable in dried whole milk and evaporated milk where the objective is to make a bland product as much like fresh milk as possible. 

The results of the ethnoarchaeological studies are summarized in Table I. From this, we can observe that soils in food preparation areas involving cooking are often low in phosphates. The alkaline nature of these soils, a result... 

Phosphoric acid is the only inorganic acid to be widely used in food preparations as an acidulant. It does, however, occur naturally in the form of phosphates in some fruits, for example, limes and grapes. In the soft drinks industry its use is confined almost entirely to cola-flavoured carbonated beverages, where its... 

The 1-deoxyosone represents the most elusive of the three intermediates, but also the most important from the standpoint of food flavor and aroma production. A large number of methyl-containing furanones, pyrones and related compounds are found in food preparations that are consistent with having been formed from this intermediate. A synthesis of this material was reported some years ago by Isuzu, et al. (10), but the yields were very low and the product was not well characterized. The workers reported that the compound gave one of the two reported isomers of "saccharinic acid", the expected degradation product in alkaline solution, along with fragmentation products. This material will be addressed (vide infra) in a later section. 

Fats occur naturally in food and play a significant role in human nutrition. Fats are used to store energy in the body, insulate body tissues, cushion internal organs, and transport fat-soluble vitamins in the blood. Fats also play in an important role in food preparation They enhance food flavor and food texture, make baked products tender, and conduct heat during cooking. 

Workers associated in food preparation must be healthy and clean. 

Even though it is difficult to assess the actual risk to humans presented by current exposure to HAAs and related compounds, it is sensible to consider the scope for reducing lifetime exposure to these substances through changes in food preparation, such as those already mentioned. 

Epoxy is used as a lining for water reservoirs, water mains, and home plumbing systems (Heim and Dietrich, 2007a). These applications can impact sensory quality of tap water in food manufacturing, food service operations, and residential homes. This effect may be most noticeable in water but residual aroma and flavor compounds may cause a taint in foods prepared with these water sources. An odor assessment, using a water industry standard flavor profile analysis method, identified a strong relationship between water (simulated tap water, pH 7.7-7.9) stored in epoxy-lined copper pipes for 3-4 days and an odor described... 

There has been some concern about the effect of alkaline conditions on the formation of toxic amino acids in corn, particularly lysinoalanine (13). However, since lysinoalanine was found in very small amounts in foods prepared under more rigorous conditions than those applied traditionally, and since the lime treatment of corn has been a processing... 

Cardamom is used as an aromatic, carminative and stimulant. The seeds have a warm, slightly pungent aromatic flavour. It is used mainly as a flavouring agent in tea and food preparations. Cardamom oil is a precious ingredient in food preparations, perfumery, health foods, medicine and beverages. 

Tallow is waxy body fat rendered from animal tissue, usually that of beef or sheep. It is isolated by heating, and allowed to solidify. Tallow has been used in leather preparation, as a lubricant, in food preparation, and in making candles and soap. It is used as food for domestic animals, mostly for poultry. Tallow candles bum quickly and have a low melting point. They were generally less expensive than wax candles, and easier to make. Suet is another name for animal fat, usually applied to that from sheep. 

As will be discussed later, the presence of lysinoalanine in foods cannot be used as an indicator of alkali treatment since lysinoalanine has been found in foods prepared without use of alkali (20).

Although modern analytical techniques have considerable precision and sensitivity, food composition tables carmot be considered to give more than an approximation to vitamin intake. Apart from the problems of biological availability (Section 1.1.2), there is considerable variation in the vitamin content of different samples of the same food, depending on differences between varieties, differences in growing conditions (even of the same variety), losses in storage, and losses in food preparation. 

Avoid contamination with unsafe water—ensure water used in food preparation is potable or boiled.
