Abstract

The invention discloses a carrageenan-cinnamon essential oil edible thin film and a preparation method thereof. The edible thin film comprises the following components in percentage by weight: 0.5-3% of carrageenan, 0.025%-2% of cinnamon essential oil, 0.5-2% of glycerol and the balance of distilled water. The preparation method of the thin film comprises the following steps of: adding the carrageenan into the distilled water, continuously and evenly stirring, adding the glycerol, putting the mixture into a 80-95DEG C water bath kettle, heating and continuously stirring, so as to obtain a carrageenan glycerol mixed solution; cooling the carrageenan glycerol mixed solution to 50-60 DEG C, adding the cinnamon essential oil, and stirring sufficiently; and putting the carrageenan glycerol mixed solution containing cinnamon essential oil into a homogenization device so as to be homogenized, then pouring onto a glass plate, drying for 24-48 hours the temperature of 30-50DEG C, cooling to room temperature and tearing down, thus obtaining the carrageenan-cinnamon essential oil edible thin film. The carrageenan-cinnamon essential oil edible thin film is used for the package of supermarket-sold chilled pork, so that the quality guarantee period of the chilled pork can be effectively prolonged.
