Market Trends of the 1990s. The United States spice market can be divided into three sectors based on appHcation industrial, ie, food processing and manufacture institutional, ie, restaurants, hospitals, schools, and military and retail. The food manufacturers and institutions account for almost 65% of U.S. spice usage, an increase from about 40% in the 1980s. Retail food outiets make up most of the remainder. 

The 35 and 50% H2O2 concentrations are used for most industrial appHcations. The standard grades contain sufficient stabilizers to ensure safety. Grades having lower stabilizer content and evaporative residue are available for specialty uses and for aseptic cleansing of containers in food processing and marketing. 

In addition, many grades of paper and paperboard are used in direct or indirect contact with foods. Thus, many mills only use paper chemicals that have been cleared for use by the U.S. Pood and Dmg Administration (PDA) (3), so that it is not necessary to segregate machine broke (off-grade paper and edge clippings that are reclaimed for their fiber value) and white water. Most of the chemicals discussed in this article are approved by the PDA for use in paper and paperboard that are intended for appHcations in food processing and packaging. However, there are various restrictions on both the specific functional uses and amounts of paper chemical additives which can be used, so the PDA status should be confirmed by the suppHer before use.

Rich sources of vitamin A include dairy products such as milk cheese, butter, and ice cream. Eggs as well as internal organs such as the Hver, kidney, and heart also represent good sources. In addition, fish such as herring, sardines, and tuna, and in particular the Hver oil from certain marine organisms, are excellent sources. Because the vitamin A in these food products is derived from dietary carotenoids, vitamin A content can vary considerably. Variation of vitamin A content in food can also result from food processing and in particular, oxidation processes (8). 

Aerated lagoons are employed for the treatment of nontoxic or nonha2ardous wastewaters such as food processing and pulp and paper. Retention time varies from 3 to 12 d, so a large land area is usually required. 

Coll boilers Used for small industry, hotel, laundry, food processing, and similar duties, where rapid but intermittent steam demand is required.

As pheophytin a and pheophytin b are the major degradation derivatives formed during extraction, food processing, and storage, some authors reconunend converting chlorophylls into the more stable pheophytins by treatment with HCl, ion exchange resin, or oxalic acid to estimate the chlorophyll contents. ...

Adsorption of (bio)polymers occurs ubiquitously, and among the biopolymers, proteins are most surface active. Wherever and whenever a protein-containing (aqueous) solution is exposed to a (solid) surface, it results in the spontaneous accumulation of protein molecules at the solid-water interface, thereby altering the characteristics of the sorbent surface and, in most cases, of the protein molecules as well (Malmsten 2003). Therefore, the interaction between proteins and interfaces attracts attention from a wide variety of disciplines, ranging from environmental sciences to food processing and medical sciences. 

Orifice scrubbers are used in industrial applications including food processing and packaging (cereal, flour, rice, salt, sugar) pharmaceutical processing and packaging and the manufacture of chemicals, rubber and plastics, ceramics, and fertilizer. Processes controlled include dryers, cookers,... 

The compilation of ideas about the usefulness of the glass transition concept in foods, presented in this section, was influenced by the following sources Rahman (1995), Chirife and Buera (1996), Fennema (1996), Roos et al. (1996), Champion et al. (2000), Labuza et al. (2001), Le Meste et al. (2002), Bhandari and Howes (2000), Slade and Levine (2003), and Roos (2003). Because there are a number of reviews (including those just listed) that specifically address the usefulness of the glass transition in food processing and stability, only a brief summary is provided here. 

The food polymer science approach is being applied successfully in the food industry for understanding, improving, and developing food processes and products. However, to date, the glass transition generally remains more of a research and development tool than a routine quality assurance measure of food processability and stability.
