Effect of Chito-oligosaccharide Coated Paper Packaging on Postharvest Freshness of Broccoli

As a biological coating agent, chitosan oligosaccharide can regulate the physiological activities of fruit and vegetable products after harvest, inhibit the growth of pathogenic microorganisms, and induce disease resistance of fruit and vegetable products, and has a good promotion effect on the preservation of fruit and vegetable products. Nie Qingyu applied different concentrations of oligochitosan to the inner layer of ordinary wrapping paper for packaging and processing broccoli, and studied the effects of different treatments on the storage quality and postharvest preservation of broccoli.

In the experiment, 1%, 2%, and 3% chitooligosaccharide aqueous solutions were used as the coating film matrix, respectively coated on the inner layer of ordinary 0.2 mm wrapping paper, and dried naturally to make chitooligosaccharide coated paper. After picking broccoli for testing, choose non-invasive green ripe, uniform size flower heads, remove the leaves, and save 10cm flower stems for processing. Fumigate with 28g/L±10% ozone gas for 30min to sterilize the surface. After random grouping, they were packaged with 1%, 2%, 3% chitosan oligosaccharide coated paper (denoted as treatment T1, T2, T3, respectively), and stored in a cold storage at 4°C, 75%-85% RH. For every 100 treatments, test the physiological and biochemical indexes every 3d, repeat 3 times. In addition, CK1 without packaging and CK2 with ordinary packaging paper were used as controls. The results showed that different concentrations of oligochitosan coated paper packaging can all reduce the postharvest weight loss of broccoli (Figure 1); delay fruit titratable acid (Figure 2), reduced ascorbic acid (Figure 4), and chlorophyll content (Figure 3) Inhibit the increase of free proline content (Figure 5); effectively maintain the sensory and nutritional quality of post-harvest broccoli, and extend the shelf life. The indicators of 2% Chitooligosaccharide coated paper packaging treatment are better than other treatments, which is the most economical and effective treatment method for broccoli postharvest preservation.
