Gong Yufen, Liu Bin, Wang Suying. Effects of the Processing on the Quality of Four Kinds of Vegetable[J]. Journal of refrigeration, 2014, 35(3). DOI: 10.3969/j.issn.0253-4339.2014.03.081.
Contents of vitamin C(Vc) and total soluble solids(TSS) were determining to analyze the effect of processing like segmentation
blanching and freezing rate on the quality of four kinds of vegetable including potato
carrot
broccoli and onion. The results show that the freezing rate within a certain range shows no significant effect on Vc and TSS of these four vegetables
the larger cuts of vegetables can effectively maintain the content of Vc and TSS and the blanching before quick-freezing causes a greater loss to Vc and TSS of carrots and onions
but it is more suitable for potato and broccoli to maintain the content of Vc and TSS.
