A USDA report indicates that between 1967 and 1988, butter consumption remained stable at 2 kg per capita, margarine dropped from 5.1 to 4.7 kg, and measured total fat intake per day dropped from 84.6 to 73.3 g (14). This study also projects that the reduced consumption of tropical oils is only temporary and will return to former use levels, possibly even higher. One reason for this projected rise in tropical oil consumption is the knowledge of the beneficial effects of medium-chain length acids high in lauric oils. There is a keen interest in omega-3 fatty acids, as well as linoleic acid, contained in fish oils. 

Somewhat analogous to these rice products is Oatrim, a material based on oat flour. It was developed at the Northern Laboratory of the USDA and is offered commercially by several firms. Oatrim contains 5% proteia, 5% P-glucan, 2% pentosans, and 83% maltodextrias. Unique properties are claimed based on the P-glucan component, and preparation of Oatrim is disclosed ia USDA pubHcations and patents. Briefly, oat flour is broken down by a-amylase, then the water-soluble component is dried and is the product of commerce, aimed at ground meat product usage.

U.S. Oleoresin Imports. Reports of the USDA Hst only paprika and black pepper oleoresins by name, and label all others, eg, capsicum, celery seed, and turmeric, as "other" (Table 3). The steady increase in the value of oleoresin imports is expected to continue. 

The USDA considers most spices generaHy recognized as safe (GRAS). There are no standards of identity or legal definitions of spices. Spices used in dmgs must meet the official standards of the US. Pharmacoepla in force. Advisory specifications may also be appHed in commercial spice trading. 

The 1993 market for LPC-type products in the United States was for dried alfalfa meal for animal feed. This product is sold for both protein and carotenoid content. The USDA Pro-Xan product attempts to obtain improved xanthophyU contents for use in egg-laying rations in addition to protein contents. The limitations to commercial development of LPC products for human food use are high capital costs as compared with the low yields of protein, seasonal availabihty of raw materials, and the need in the United States for FDA approval of the products.

Xanthan Gum. As a result of a project to transform agriculturally derived products into industrially usefiil products by microbial action, the Northern Regional Research Laboratories of the USDA showed that the bacterium TCanthomonas campestris - noduces a polysaccharide with industrially usefiil properties (77). Extensive research was carried out on this interesting polysaccharide in several industrial laboratories during the eady 1960s, culminating in commercial production in 1964. 

Upon satisfactory deterrnination of nontoxicity of a lubricant, the USDA issues one of two ratings HI for use where there is incidental or possible food contact as by splashing or dripping from machinery above an edible product, or H2 for no food contact as in sealed gear boxes or machinery below a product line (82—84). These classes include a number of petroleum and synthetic oils and greases. 

Nutritional Labeling Descriptors. In order to avoid confusion, descriptive terms must be accompanied by definitions which adequately explain the terms. In the case of nutrition-related claims, analytical sampling offers a means of assuring the accuracy of the stated claims. The USDA s FSIS has proposed a Hst of descriptors relevant for meat and poultry products (Table 3). 

The USDA neither guarantees nor warrants the standard of the product, and the use of the name by USDA implies no approval of the product to the exclusion of others that may also be suitable. 

English or Persian Walnuts. Walnuts are produced in more countries than any of the other tree nuts but production figures are unrehable. The United States is the leading producer of walnuts, at 234,913 t in 1990—1991 (valued at 279,720,000). Production, mostly in Califomia and Oregon, is nearly one-half of the world total. Many countries produce substantial quantities of walnuts. The USDA considers estimates of the commercial crop more rehable than the total yearly production figures, which in 1990—1991 were 152,500 t in China, 66,000 t in Turkey, 17,000 t in India, 13,000 t in Prance, and 12,000 t in Italy. Walnuts, both in-sheU and shelled, may be imported from many countries, eg. Prance, Italy, China, Turkey, and India. Most imported walnuts are smaller than domestic walnuts and are used by the confectionery and baking industries.

Chemical fertiliser is the predominant market for langbeinite. Comparatively small but increasing amounts of langbeinite are used by the animal feed ingredient industry (see Feeds and feed additives). Producers who supply this market must take special precautions to be sure that any langbeinite intended as an animal feed ingredient meets all USDA specifications for toxic heavy metals and other impurities.

An extensive pesticide properties database was compiled, which includes six physical properties, ie, solubiUty, half-life, soil sorption, vapor pressure, acid pR and base pR for about 240 compounds (4). Because not all of the properties have been measured for all pesticides, some values had to be estimated. By early 1995, the Agricultural Research Service (ARS) had developed a computerized pesticide property database containing 17 physical properties for 330 pesticide compounds. The primary user of these data has been the USDA s Natural Resources Conservation Service (formerly the Soil Conservation Service) for leaching models to advise farmers on any combination of soil and pesticide properties that could potentially lead to substantial groundwater contamination.
