Summary:
β-glucosidase is a key enzyme for the conversion of glycosides, a precursor of aroma in fresh leaves, into free aroma. The dynamic study on the changes of β-glucosidase activity during the withering of safflower and fermentation showed that during the withering period, the enzyme activity was gradually enhanced, and the intelligence was 2-2.5 times that of fresh leaves, and the effect of amine withering temperature and withering degree; during the fermentation process, the enzyme activity decreased rapidly, and the higher the fermentation temperature, the greater the decrease of its activity.

Summary:
The composition and content of glucosinolates (glucosinolates) in cabbage, mustard and cabbage in Brassica were evaluated. The results showed that the total content of glucosinolate in cabbage was the highest, followed by cabbage, mustard, kale and pakchoi. Different varieties have different types and contents of glucosinolate. In cabbage, the main glucosinolates in Chinese cabbage are 3 butenyl and 1 methoxy 3 indolyl methyl glucosinolates, 3 butenyl and 2 hydroxy 3 butenyl glucosinolates in cabbage, and 1 methoxy 3 indolyl methyl and 4 pentenyl glucosinolates in moss. In mustard, two different types of glucosinolate were found. Allyl glucosinolate is the main glucosinolate in cabbage and mustard, accounting for about 90% of the total content. However, 3-butenyl is the main glucosinolate in small leaf mustard, accounting for about 70% of the total content. Kale contains mainly 3 indolyl methyl glucosinolate and 3 methyl thiopropyl glucosinolate. The content of 4 methyl thiobutyl glucosinolate is the highest in kale, in addition, the content of 3 butylene glucosinolate is also relatively high. In cabbage, 2 hydroxy 3 butylene glucosinolate is the main component, accounting for about 4 3% of the total content, allyl glucosinolate and 3 indolyl glucosinolate account for about 20% of the total content. The content of sulforaphane precursor 4 methyl thiobutyl glucosinolate in kale can reach 12 4 .1 μmol/10 0gFW, which is a cruciferous vegetable with great anti-cancer value
