| Research methods on lignification of postharvest bamboo shoots were reviewed at home and abroad in recent years, mainly including modified atmosphere storage, low temperature processing, exogenous chemicals. The mechanisms of inhibiting lignification were revealed by various processing methods. The results showed that it inhibited the increase of key enzymatic activity of the lignin biosynthesis (PAL, POD, CAD and C4H); and improved the activity of enzymes related to reactive oxygen metabolism (SOD, CAT and APX). It can also delay the reduction of moisture content and nutritional values during storage, and inhibit the growth of pathogen and the content of lignin and cellulose during storage, which can retard the lignification of bamboo shoots and maintain the eating quality. These results provide certain references on quality improvement and postharvest fresh-keeping in future. |
