Abstract:

To develop an edible composite film for storage of boiled mutton, taking rosemary (3%) composite film, tea polyphenol (3%) composite film and preservative film as control groups, boiled mutton was treated with different concentrations (1%, 3%, 5%) of wine pomace polyphenol chitosan CMC composite film and control films. The sensory characteristics, pH, color, thiobarbituric acid (TBA), TVB-N and total bacterial count of boiled mutton during cold storage [(4±1) ℃] were analyzed. The best composite film was selected according to the results, and volatile substances during storage were studied. The results showed that 5% wine pomace polyphenol chitosan CMC composite film were selected as the best treatment, it could effectively improved the color of mutton, delayed lipid oxidation, on the 9th day of storage, sensory characteristics and antibacterial activity of 5% polyphenol film treatment group were significantly (P<0.05) better than other composite film treatment groups, TVB-N was lower than the limit value; On the 12th day of storage, the pH value of 5% polyphenol film treatment group was significantly (P<0.05) lower than that of other composite film treatment groups. The storage time of mutton could be delayed to 9 days. There were some differences in volatile compounds among the 5% polyphenol film treatment groups with different storage time. Therefore, wine pomace polyphenol chitosan CMC composite film could effectively maintain the color of mutton during storage, inhibit oxidation, reduce corruption, prolong shelf life, and effectively maintain the edible quality of mutton during storage.
