Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with examples.

[0019] A method for preparing longan enzyme from longan core, is characterized in that, comprises following concrete steps:

[0020] (1) Processing of raw materials: clean the longan core, remove the longan core skin, and then put the longan core in an oven to dry. The water is beaten with a colloid mill to obtain the longan nucleus slurry;

[0021] (2) Gelatinization: heat the longan nucleus slurry at 90°C to 95°C for gelatinization, and the gelatinization time is 30min to 60min;

[0022] (3) Enzymolysis: Add 10000 U of medium-temperature α-amylase to the gelatinized longan nucleus slurry, the enzymolysis time is 180min, and the enzymolysis temperature is 70°C;

[0023] (4) Sterilization: adjust the reducing sugar content of the enzymolysis solution to 25%, and add peptone, the amount of peptone is 1% of the mass of the enzymolysis solution, and sterilize the enzymolysis solution ...

Abstract

The invention discloses a method for preparing longan ferment from a longan kernel. The method comprises the following steps: processing longan, and pasting; performing enzymolysis, sterilizing, fermenting, and spray-drying, thereby finally obtaining the longan ferment which is rich in nutrients. The longan ferment prepared by adopting the method is rich in nutritional substances such as carbohydrate, protein, superoxide dismutase, protease, lactic acid, phenolic substance, lactic acid viable count and the like. The longan ferment can be used as a novel health care product and a cosmetic additive, and thus nutritional and medicinal values of the longan kernel are fully utilized, and the variety of a longan processed product is increased.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing longan enzyme from longan kernels. Background technique [0002] Longan kernel is astringent, flat, slightly qi, light and slightly bitter. It has the functions of stopping bleeding, relieving pain, regulating qi and eliminating dampness, etc. It can treat wounds, hernia, scabies, eczema, etc. Nootropic effect. Singaporean Yean Yean Soong et al. studied the relationship between the content of phenolic substances in longan core and the antioxidant capacity. The results showed that longan core has high antioxidant capacity, and its antioxidant capacity is stronger than that of pulp. 70% of the antioxidant substances in longan Exist in longan core. [0003] Xiao Gengsheng et al. conducted a systematic analysis of the nutritional components of longan kernels, and found that the main nutritional components in longan kernels are 4.81% water, 60.9% starch, 14.13% ...
