The Megazyme procedure requires the company s Total Starch Assay Kit, which contains most of the necessary enzymes and chemicals. This procedure was approved by the American Association of Cereal Chemists (AACC Method 76-13 AACC, 1976) and the Association of Official Analytical Chemists (AOAC Method 996.11) following an extensive collaborative AACC/AOAC interlaboratory evaluation (McCleary et al., 1997b). The procedure is simpler than a previously reported method (AACC, Method 76-12). The procedure by Holm et al. (1986) described in the Alternate Protocol uses enzymes and chemicals purchased individually. 

For laboratories with minimal equipment and requirements for results in a minimum amount of time, the Holaday-Velasco minicolumn method has been adopted for aflatoxin in corn by the Association of Official Analytical Chemists (AOAC) as well as the American Association of Cereal Chemists (AACC). 

According to him, in 1967 the President of the American Association of Cereal Chemists (AACC) asked Whistler to explore the possibility of creating a Carbohydrate Division. Thereupon, he formed a committee, whieh quiekly developed and presented to the AACC Board of Directors a statement of purpose and operating procedures for the Division, and received authority fiom it to form a Division. He served as its first Chair. 

Recently, the most commonly used in vitro methods were extensively evaluated and a simplified version was proposed (McCleary method). Here, samples are treated with an amyloglucosidase-pancreatic amylase mixture only and the insoluble residue, after washing with ethanol, is dispersed with KOH, followed by the amyloglu-cosidase step to yield glucose. This protocol has been accepted by AOAC International (AOAC method 2002.02) and the American Association of Cereal Chemists (AACC method 32-40) (Table 4). 

There has been much debate of the definition of dietary fiber and in particular whether it should include carbohydrates other than nonstarch polysaccharides. Recently, the American Association of Cereal Chemists (AACC) proposed a new definition of dietary fiber, which would include both oligosaccharides and resistant starch as well as associated plant substances. This new definition would also require complete or partial fermentation and demonstration of physiological effects such as laxation, and reduction in blood glucose or blood cholesterol. A similar approach to include beneficial physiological effects is also proposed by the Food and Nutrition Board of the US Institute of Medicine.

Determination of four tocopherols and four tocotrienols in vegetable oils and fats by the official American Oil Chemists Society method is based on separation by normal-phase HPLC and fluorescence detection (AOCS, 1990). Oil samples are dissolved in hexane, whereas margarines and other fats containing vitamer esters need a cold saponification step to liberate the vitamers. The American Association of Cereal Chemists has a method to analyze vitamin E in various foods. This method (AACC, 1997) is applicable to a vitamin E range of 1 x 10" - 100%, and it includes hot saponification and separation by reversed-phase HPLC. Results are calculated as a-tocopherol acetate. The Royal Society of Chemistry has approved a method to analyze vitamin E in animal feedstuffs by normal-phase HPLC after the vitamers have been liberated by hot saponification (Analytical Methods Committee, 1990). 

American Association of Cereal Chemists. The American Association of Cereal Chemists is one of the most renowned professional societies in its field. It was founded in 1915 by a handful of chemists who were connected with the flour milling industry. Today the membership of this organization approaches 1000. The first publication of the AACC was a journal which was published from 1915 through 1923. In 1922 the American Society of Milling and Baking Technology joined ranks with the... 

The American Association of Cereal Chemists appointed an Abstract Committee to study the problem of abstracts and indexes. Upon the recommendation of the committee, arrangements were made with Biological Abstracts (14 ) to publish a separate section. Section J, Abstracts of Cereals and Cereal Products. This has been published since 1948. Financial support is given by the AACC and the Millers National Federation (12). It is too early to evaluate Section J as a tool. Since it is part of so huge a service it cannot hope to attain the position of a current review-type service. There are no plans for separate indexing the index to the complete edition is included with each section subscription. The December 1951 issue has a Numerical Key to Contents of Section J. The latest subject index to Biological Abstracts is Volume 23, 1949. However, future editorial policy may improve this situation.

Dr. MacRitchie s awards include the F. B. Guthrie Medal of the Cereal Division of the Royal Australian Chemical Institute and the Thomas Burr Osborne Medal and George W. Scott Blair Memorial Award of the American Association of Cereal Chemists (now AACC International). He has been a member of the editorial boards of Advances in Colloid and Interface Science, Cereal Chemistry, and Journal of Cereal Science. Presently, he is editor-in-chief of Journal of Cereal Science. 

In the agriculture and animal feed industries NIR instruments, and in particular discrete filter instruments, have found the widest application in the analysis of grain and flour. Protein, moisture, hardness, and baking quality are all examples of analysis that have been performed by NIR instrumentation, both off- and online. Several countries, including the USA and Canada, have adopted NIR protein analysis as national standards to gauge the level of payment for wheat. The protein method was approved by the AACC (American Association of Cereal Chemists) in 1983.
