Embodiment 1

[0018] This embodiment provides a preparation method of Rosa roxburghii freeze-dried granules. First, the raw roxburghii juice is pretreated and then concentrated in vacuum, and then vacuum freeze-dried to finally obtain Rosa roxburghii freeze-dried granules. The specific steps are:

[0019] (a), the original juice of roxburghii is allowed to stand still for 5 hours, and filtered to obtain the original juice of roxburghii with impurities removed.

[0020] (b) Concentrating the impurity-removed Rosa roxburghii raw juice in vacuum at a concentration temperature of 25°C to 1 / 4 of the original volume to obtain a concentrate.

[0021] (c) Add 6% of the mass of the protective agent and 1% of tert-butanol into the concentrated solution, stir until they are completely dissolved, and adjust the pH to 6 to obtain a solution to be dried.

[0022] Wherein, the protective agent is composed of glucose and trehalose, and the mass ratio of glucose to trehalose is 1:2.

[0023] (d), vacuum fr...

Embodiment 2

[0028] This embodiment provides a preparation method of Rosa roxburghii freeze-dried granules. First, the raw roxburghii juice is pretreated and then concentrated in vacuum, and then vacuum freeze-dried to finally obtain Rosa roxburghii freeze-dried granules. The specific steps are:

[0029] (a), the original juice of Rosa roxburghii was left to stand still for 10 hours, and filtered to obtain the original juice of Rosa roxburghii with impurities removed.

[0030] (b) Concentrating the impurity-removed Rosa roxburghii original juice in vacuum at a concentration temperature of 23°C to 1 / 5 of the original volume to obtain a concentrate.

[0031] (c) Add 8% of the mass of the protective agent and 3% of tert-butanol into the concentrated solution, stir until they are completely dissolved, adjust the pH to 7, and obtain a solution to be dried.

[0032] Wherein, the protective agent is composed of glucose and trehalose, and the mass ratio of glucose to trehalose is 1:3.

[0033] (d...

Embodiment 3

[0038] This embodiment provides a preparation method of Rosa roxburghii freeze-dried granules. First, the raw roxburghii juice is pretreated and then concentrated in vacuum, and then vacuum freeze-dried to finally obtain Rosa roxburghii freeze-dried granules. The specific steps are:

[0039] (a), the original juice of Rosa roxburghii was left to stand for 15 hours, and filtered to obtain the original juice of Rosa roxburghii with impurities removed.

[0040] (b) Concentrating the impurity-removed Rosa roxburghii original juice in vacuum at a concentration temperature of 20°C to 1 / 4 of the original volume to obtain a concentrate.

[0041] (c) Add 9% of the mass of the protective agent and 2% of tert-butanol into the concentrated solution, stir until they are completely dissolved, and adjust the pH to 8 to obtain a solution to be dried.

[0042] Wherein, the protective agent is composed of glucose and trehalose, and the mass ratio of glucose to trehalose is 1:1.

Abstract

The invention discloses a preparation method of roxburghii freeze-dried granules, which belongs to the field of biological products. Rosa roxburghii raw juice is concentrated after pretreatment, and then subjected to a vacuum freeze-drying process to obtain the roxburghii lyophilized granules; wherein, the The concentration is vacuum concentration, and the concentration temperature is not higher than 25°C. The roxburghii freeze-dried granules obtained by the invention have less loss of active ingredients such as SOD, and the finished product has excellent quality, rich nutrition, long storage time, and is convenient for transportation and use.

Description

technical field [0001] The invention belongs to the field of biological products, in particular to a preparation method of roxburghii freeze-dried granules. Background technique [0002] Rosa roxburghii is rich in nutrients. According to analysis and determination, it is rich in vitamin C, SOD, antioxidant enzymes and carotene, etc., and also contains a variety of mineral nutrients. Among them, SOD is an internationally recognized active substance with anti-aging, anti-radiation, and anti-cancer properties, but the composition of SOD is unstable. At present, the traditional thorn pear production process takes a long time to process materials, and it is difficult to preserve the active SOD under high temperature sterilization. More, not conducive to industrialization, large-scale deep processing. Therefore, how to overcome the deficiencies of the prior art and ensure the high efficiency of the product is an urgent problem to be solved in the current technical field. Conte...
