【摘要】 利用异VC钠、柠檬酸、焦亚硫酸钠的单一与复配使用对半干鸡肉宠物食品进行护色研究。单一护色实验结果表明,护色效果焦亚硫酸钠>柠檬酸>异VC钠,复配护色实验表明柠檬酸能够增强异VC钠和焦亚硫酸钠的护色效果,柠檬酸:焦亚硫酸钠(质量比)=2:1时,对维持鸡肉宠物食品颜色金黄色,抑制的颜色加深变黑效果显著。更多还原

【Abstract】 Color fixatives such as sodium erythorbate,citric acid,sodium metabisulfite were used separately or together to study their effects on the color protection of semi-dry chicken pet food.The results of single color protection experiments showed that sodium metabisulfite had the best effectiveness in the color protection of semi-dry chicken pet food,followed by citric acid and sodium erythorbate.Citric acid could enhance the protecting effects of the other two color fixatives on the color of semi-dry chicken pet food.When the mixing ratio of citric acid and sodium metabisulfite was 2:1(m/m),the golden yellow color of semi-dry chicken pet food was well maintained,and color darkening was retarded dramatically.更多还原
