Crops, food, and feed. The first recommended method is based on the Dutch Multiresidue Method 2 for A-methylcarbamates, which was originally developed by de Kok et The method has recently been validated by DuPont Crop Protection and Batelle, Geneva Research Centres, for the analysis of methomyl and oxamyl in dry, high-water, high-fat, and high-acid content crops and in various grape processed products. The limit of detection for each analyte is 0.003-0.005 mg kg . ... 

Adapted grape processing equipment is generally used for stripping. A low proportion of comhs makes it easier to press out the mash. If the proportion is too high, unwanted tannins get into the juice.

Green extraction processes (viz., subcritical water and sub- and supercritical carbon dioxide extraction) are the most promising methods for industrial implementation. In fact, these methods are excellent for isolating anthocyanins and other polyphenols from grape processing wastes [196].
