摘要: 就不同脱乙酰度、不同浓度和溶解到不同浓度醋酸的壳聚糖对冷却猪肉中的微生物的抑制效果进行研究,结果表明,壳聚糖对猪肉中的微生物有明显的抑制效果,且壳聚糖浓度为5 mg/mL,壳聚糖脱乙酰度(DAC)≥95%,壳聚糖溶于醋酸浓度为1%时,对肉品中微生物的抑制效果较好.Abstract: Effect of chitosan on inhibitory of microorganisms in chilled pork was preliminarily studied using different degree of deacetylation, different concentration chitosan, and different concentrations acetic acid (as dissolved solution). The results showed that chitosan had significant inhibitory effect on microorganisms in chilled pork. When chitosan concentration of 5 mg/mL dissolved in 1% acetic acid, degree of deacetylation of chitosan≥95% had the best effect of inhibition of microorganisms in chilled pork.
