because of thermal oxidation Monster Headphone Pro

p In order to take care of the vegetable color, or eliminate smell , astringent , and oxalic acid , certain vegetables before cooking, blanch the . However, nutrition angle , boiling water can boost decrease in water-soluble nutrients , cabbage trouble at 100 C , two minutes , the speed of lack of vitamin C up to 65% ; hot a lot more than 10-20 minutes , vit c, almost murdered . Therefore , boiled water must be used appropriate approaches to minimize the loss of nutrients . using boiling water, more water, a brief period of one's time Cheuk water treatment, can aid in eliminating the warmth diminished nutrients .

 Oxidase within the vegetable tissue , it will accelerate the oxidation of vit c , specially in the water temperature of 60 C to 80 C , the greatest activity . Oxidase from the boiling water , thermally unstable , and soon lose their activity , while boiling water is no oxygen , thus lowering the losses the result of vitamin C because of thermal oxidation Monster Headphone Pro . Cheuk water plus 1% salt , the vegetables inside a physiological salt solution of soluble nutrients in vegetables can spread towards the reduce in the water . / p p blanch the vegetables as much as possible complete morphological , reduce heat and touch the tank area . With the coal are more circumstances , ought to be batch feed to make sure that the raw material during the higher temperature of water . / p p blanch the vegetables climate is relatively high it in the water and oxygen in an airplane contacts the thermal-oxidative effect , a continuation of your nutrient loss .

 Therefore, blanch the vegetables really should be cooled by cooling water . The common device is to use large amounts of cold water or cold air to cool heat Monster Headphone Studio . The first as the vegetables set the stream , due to the action of water , decrease in soluble nutrients ; warriors as there is no such factors exist, the higher . In line with the analysis , the vegetables after Cheuk water treatment , vitamin C , the normal save rate of 84.7% .
