金针菇保健果冻的研制
金针菇保健果冻的研制(6500字)
摘 要:本研究初探果味金针菇保健果冻的工艺流程 ,以金针菇提取液、果冻粉和桔子汁为原料,采用单因素和正交试验对金针菇保健果冻的加工工艺进行研究,通过感官评定得出最佳的工艺条件和最佳杀菌条件。试验结果表明,最佳配方:金针菇原液10%,桔子汁 35 %,白砂糖 13 %,柠檬酸 0.2 %,果冻粉 1.5 %,山梨酸钾0.05 %,其余为水。在此参数下可研制出组织形态、色泽和口感均优良的果冻。最佳杀菌工艺条件为:90℃杀菌5min。

Study on the Flammulina velutipes Health Jelly
Abstract: In this study , Flammulina velutipes were extracted as raw material for processing jelly powder and orange juice. Study the procession of making Flammulina velutipes and adopt the method of the single factor and orthogonal tests to research the technology of making Flammulina velutipes . optimum process conditions and the best sterilization conditions aredetermined by sensory evaluation. The results show that the optimum ratio is 35% orange juice、10% flammulina velutipes、42%water、13% sugar、0.2% citric acid、1.5% jelly powder、0.05% potassium sorbate。Jelly of organizational form、good color and taste can be developed referring to this parameter. The best sterilization process condition is 90 ℃ and sterilizing for 5mins.
