p In order to help keep the vegetable color, or take away the smell , astringent
, and oxalic acid , certain vegetables before cooking, blanch the . However,
nutrition standpoint , boiling water can increase the losing water-soluble
nutrients , cabbage domestic hot water at 100 C , two minutes , the velocity of
decrease of vitamin C about 65% ; hot in excess of 10 minutes , vit c, almost
dismissed . Therefore , boiled water should be used appropriate methods of
minimize the decline of nutrients . using boiling water, more water, much very
less time of one's time Cheuk water treatment, helps to reduce the warmth lack
of nutrients .
Oxidase contained in the vegetable tissue , it may possibly
accelerate the oxidation of vitamin C , particularly in the tank temperature of
60 C to 80 C , the greatest activity . Oxidase inside boiling water , thermally
unstable , and shortly lose their activity , while boiling water is no oxygen ,
thus reducing the losses brought on by vitamin C caused by thermal oxidation .
Cheuk water plus 1% salt , the vegetables in any physiological salt solution of
soluble nutrients in vegetables can spread with the delay in water . / p p
blanch the vegetables where possible complete morphological , reduce heat and
touch the tank area . In the recycleables are definitely more circumstances ,
need to be batch feed to make sure that the raw material inside higher water
temperature Beats by Dr Dre by
NFL .
/ p p blanch the vegetables temperature is relatively high it from
your water and oxygen uphill contacts the thermal-oxidative effect , and that is
a continuation with the nutrient loss . Therefore, blanch the vegetables ought
to be cooled by cooling water . The commonly used strategy is make use of
massive amounts of cold water or cold air to cool down the heat Beats by Dr Dre by MLB . Ad
units as the vegetables positioned in the tank , mainly because of the action
water , loss in soluble nutrients ; warriors nevertheless there is no such
factors exist, better . Based on the analysis , the vegetables after Cheuk water
treatment , vitamin C , a typical save rate of 84.7% .
