摘要： Cinnamaldehyde is one of the most effective anti-fungal and anti-aflatoxigenic plant extracts. However, the high volatility, irritating odor and instability under adverse abiotic factors restrict its direct application in food in-dustry. Previous studies indicated that the encapsulation of essential oils with calcium alginate could protect their active compounds from environmental conditions and increase their functional capabilities. Herein, the cinnamaldehyde microcapsules (Cin-Mc) were developed on the basis of calcium alginate polymer, and its physico-chemical properties and bio-efficacies were characterized. Cinnamaldehyde was embedded in calcium alginate and the Cin-Mc was successfully made. Compared with free cinnamaldehyde, the thermal stability was enhanced, and irritating odor was decreased in Cin-Mc. Most importantly, Cin-Mc exhibited sustained release of cinnamaldehyde for 20 days at 25 degrees C, which leads to substantially enhanced anti-fungal and anti-aflatoxigenic effect against Aspergillus flavus during 4-month storage of unshelled peanut kernels, as compared to free cin-namaldehyde. Due to Cin-Mc's potent antioxidant and antifungal properties, stored peanuts could be effectively preserved against from lipid peroxidation and fungal contamination. Taken together, Cin-Mc displayed better application prospects in food storage than free cinnamaldehyde.
