p In order to take care of the vegetable color, or take away the smell ,
astringent , and oxalic acid , certain vegetables before cooking, blanch the Beats

boiling water can improve the losing water-soluble nutrients , cabbage very hot
water at 100 C , two minutes , the pace of losing ascorbic acid about 65% ; hot
more than Continuous , ascorbic acid, almost murdered . Therefore , boiled water
should really be used appropriate techniques to minimize several nutrients .
using boiling water, more water, a short time of your time Cheuk water
treatment, can lessen the warmth reduction in nutrients . Oxidase within the
vegetable tissue , it could possibly accelerate the oxidation of ascorbic acid ,
particularly in the pool temperature of 60 C to 80 C , the very best activity .
Oxidase inside the boiling water , thermally unstable , and very soon lose their
activity , while boiling water is no oxygen , thus reducing the losses because
of vit c thanks to thermal oxidation . Cheuk water plus 1% salt , the vegetables
within a physiological salt solution of soluble nutrients in vegetables can
spread towards slow in the water Beats

possible complete morphological , reduce heat and touch the river area . With
the coal tend to be more circumstances , really should be batch feed to make
sure that the raw material within the higher hot and cold levels . / p p blanch
the vegetables temperature is relatively high it with the water and oxygen in an
airplane contacts the thermal-oxidative effect , a continuation belonging to the
nutrient loss . Therefore, blanch the vegetables ought to be cooled by cooling
water . The common technique to work with a lot of cold water or cold air to
cool down heat . Hmo's because the vegetables placed into this type of water ,
with the action water , reduction in soluble nutrients ; the latter while there
is no such factors exist, the more effective . In line with the analysis , the
vegetables after Cheuk water treatment , ascorbic acid , the standard save rate
of 84.7% .
