Grapes, one of the most widely consumed fruits, present commerce challenges due to their short shelf life. One promising solution is chemical cross-linking polymers such as gelatin and pectin, which can create stronger more biodegradable networks. This study evaluated gelatin/pectin extend life ripe grapes, using citric acid a cross-linker. Three different ratios pectin (1:1, 2:1, 1:2) were tested in coatings applied grapes. The results showed that 1:1 ratio (gelatin/pectin) was effective delaying ripening An analysis characteristics cross-linked networks revealed formation covalent bonds between polymers, confirmed by FTIR, X-ray diffraction, electron microscopy. coverage superior, maintaining visual quality grapes loss mass firmness during 10-day storage period. Grapes covered with this mixture less reduction lower accumulation sugars, demonstrating its effectiveness fruit.

Quality inspection of fruits and vegetables linked to food safety monitoring quality control. Traditional chemical analysis physical measurement techniques are reliable, they also time-consuming, costly, susceptible environmental sample changes. Hyperspectral imaging technology combined with deep learning methods can effectively overcome these problems. Compared human evaluation, automated improves efficiency, reduces subjective error, promotes the intelligent precise fruit vegetable inspection. This paper reviews reports on application hyperspectral in various aspects assessment. In addition, latest applications technologies fields safety, internal quality, external reviewed, challenges future development directions this field prospected. has shown significant advantages inspection, especially improving accuracy efficiency. Future research should focus reducing costs, optimizing equipment, personalizing feature extraction, model generalizability. lightweight models balance accuracy, enhancement database importance quantitative be brought attention. These efforts will promote wide improve its practicability actual production environment, bring important progress for management.
