- 摘要:
- 以涂膜材料(大豆分离蛋白、海藻酸钠、壳聚糖)和蔬菜型夜香花为试材，采用正交优化实验法，研究涂膜保鲜配方对夜香花贮藏期间感官评价、脱花率、失重率、多酚氧化酶（PPO）活力、维生素C含量等指标的影响。结果表明：复合涂膜保鲜配方可有效地保持夜香花的感官质量，抑制脱落率升高，降低失重率，抑制PPO活力，减少维生素C含量的损失。最佳配方为：大豆分离蛋白浓度为3%、海藻酸钠浓度为0.25%、壳聚糖浓度为0.7%。
- Abstract:
- Taking coating material (soy protein isolated(SPI) and sodium alginate and chitosan) and vegetable night fragrant flower as test materials，the fresh keeping effect of the formulation of composite coatings on night fragrant flower was studied by the orthogonal experiment method.The results showed that the composite coatings solution could effectively maintain the sensory quality of fragrant night，increase inhibit shedding rate，reduce weight and vitamin C content loss，inhibit PPO activity.The optimal formulation of composite coatings for night fragrant flower fresh keeping was that SPI concentration of 3%，sodium alginate concentration of 0.25%，chitosan concentration of 0.7%.
