Methods are described for the extraction and quantitation of endogenous barley thiols and disulphides. Thiols and disulphides, together with added internal standards, are extracted from ground barley tissues (embryos or degermed grains) and the thiols in the extract are trapped on columns of beaded p-hydroxymercuribenzoyl-agarose (p-HMB-agarose). After elution they are derivatised with 5,5′-dithiobis (2-nitrobenzoic acid) and the derivatives are separated and quantified by hplc. The disulphides in the effluent from the p-HMB-agarose column are collected on a silica-based ion exchange material. After elution they are reduced to thiols and, after derivatisation, they are assayed by hplc. Dry barley embryos contain substantial quantities of glutathione, progressively lesser quantities of oxidised glutathione, cystine and cysteine and traces of γ-glutamyl cysteine and cysteinyl glycine. 相似文献

Fruit and vegetable juices are used due to convenience. The juices are rich in various minerals, vitamins, and other nutrients. To process the juices and their clarification and/or concentration is required. The membranes are being used for these purposes. These processes are preferred over others because of high efficiency and low temperature. Membranes and their characteristics have been discussed in brief for knowing suitability of membranes for fruit and vegetable juices. Membrane separation is low temperature process in which the organoleptic quality of the juice is almost retained. In this review, different membrane separation methods including Microfiltration, Ultrafiltration, and Reverse osmosis for fruit juices reported in the literature are discussed. The major fruit and vegetable juices using membrane processes are including the Reverse osmosis studies for concentration of Orange juice, Carrot juice, and Grape juice are discusses. The Microfiltration and Ultrafiltration are used for clarification of juices of mosambi juice, apple juice, pineapple juice, and kiwifruit juice. The various optimized parameters in membranes studies are pH, TAA, TSS, and AIS. In this review, in addition to above the OD is also discussed, where the membranes are used. 相似文献
