basic introduction:

canned litchi in syrup is a kind of canned litchi, and the main ingredient is litchi. Litchi is a subtropical fruit tree, and its flesh is translucent and coagulated when fresh, which is delicious. Canned lychee in syrup has the effects of tonifying lung, calming heart, harmonizing spleen and appetizing.

Safety hazard:

In order to maintain the original color of litchi, canned litchi in syrup is prone to excessive sulfur dioxide, so consumers should be vigilant. Some scholars have determined that the optimal combination of sulfur-free color fixative for canned litchi in syrup is .3%VC+.1% phytic acid +.25%ZnCl2+2.%NaCl through L9(34) orthogonal experiment. The canned litchi in syrup was processed by the improved process of the optimal sulfur-free color fixative. The samples were stored at room temperature and natural light, and the browning intensity of litchi pulp was determined every two months during storage. The results showed that the optimal sulfur-free fixative treatment could effectively inhibit the browning of litchi pulp, and the color and browning intensity of litchi pulp stored for 12 months had no obvious change. Compared with .3%NaHSO3 treatment, the optimal sulfur-free fixative was a better substitute for sodium bisulfite.
