Study on performance influencing factors of konjac glucomannan-carrageenan edible composite packaging film
The konjac glucomannan-carrageenan edible composite packaging films were prepared.The mechanical performance and the optical performance of the edible film were tested.Results showed that the mass ratio,glycerin content,water bath temperature had great influence on the performance of composite films,when the mass ratio of composite film konjac purified powder and carrageenan was 3∶1,glycerin content was 10％ (mass ratio),water bath temperature was 60℃,the comprehensive mechanical performance and optical performance of the composite films was better.Under this condition,the tensile strength of the composite films was 9.582MPa,the breaking elongation was 54.6％,luminousness was 92.2％,haze was 20.67％.
