Potato processing formation

It also appears that traditional forms of food processing may not be as safe as expected. The example of the formation of acrylamide in different heat-processed foods may be cited (see Chapter 13 of this volume). However, there are no incontrovertible answers to the questions is acrylamide in food harmful for consumers , and what is the average intake The American Council on Science and Health states that there is no credible evidence that acrylamide in foods poses human cancer risk. New Zealand food safety experts, using a no observable adverse effect level for acrylamide of 0.1 mg per kg bodyweight, also estimate that people eating fried potatos and crisps (products suspected to contain the largest amounts of acrylamide) are a very low risk of cancer from this source. European Union experts decided that the risk of exposure to polyacrylamide in food remains undetermined (Sharp, 2003). 

The production of CDs via enzymatic reaction with starch has been recently reviewed (i 7). CGTase is an extracellular protein and is usually isolated as a crude mixture from the medium. This crude protein is used directly for industrial fermentations. The basic process involves standard enz3miatic fermentation, with careful attention to reaction temperature. All three CDs and some Unear oligosaccharides are normally produced. Yields are highly dependent on the source of starch substrate. Potato starch is normally used or an extract of potato starch is often added to other starches 18-19), The potato starch component(s) responsible for stimulating CD formation have not been determined. Low starch concentrations (5%-10%) are normally used industrially. Published yields are in the 50% - 80% conversion range.
