Embodiment 1

[0050] Preparation of soft-shelled turtle skin collagen:

[0051](1) Carry out pretreatment to the soft-shelled turtle skin: sort the soft-shelled turtle skin to remove impurities, wash and dry to a water content of 10%, and make fish skin powder after pulverization, and then carry out acid treatment and decalcification to the fish skin powder, acid The treatment process is that the concentration of hydrochloric acid is 0.4mol / L, the ratio of solid to liquid is 1:10, and the treatment time is 4 to 8 hours, and then alkali treatment is carried out to remove non-collagen impurities and pigments in the fish skin. The alkali treatment process is sodium hydroxide concentration It is 0.15mol / L, the ratio of solid to liquid is 1:10 (m / v), and the treatment time is 24h.

[0052] (2) Degreasing the pretreated soft-shelled turtle skin: according to the solid-liquid ratio of 1:30 (m / v), add the pre-treated soft-shelled turtle meal into 10% n-butanol solution, soak for 24h, and n-butanol ...

Embodiment 2

[0076] The preparation of soft-shelled turtle skin collagen and the preparation of polysaccharide of golden blessing mushroom are the same as embodiment 1.

[0077] The preparation of collagen / polysaccharide-embedded microcapsule plant essential oil comprises the following steps:

[0078] (1) Preparation of mixed plant essential oil:

[0079] Under microwave-ultrasonic and nitrogen atmosphere conditions, blueberry leaves and roses are extracted with a mixture of ethanol, ethylene glycol and acetone at a mass ratio of 1:1:1 to obtain mixed plant essential oils;

[0080] (2) Preparation of microcapsule plant essential oil nucleus:

[0081] Take 4g of soft-shelled turtle skin collagen and 4g of jinfu mushroom polysaccharide prepared above and dissolve them in distilled water at 40°C, and dissolve while stirring to make a saturated solution;

[0082] Add 12 g of the mixed plant essential oil of step (1) dropwise under stirring conditions, and emulsify to obtain a homogeneous mix...

Embodiment 3

[0096] The preparation of collagen / polysaccharide-embedded microcapsule plant essential oil comprises the following steps:

[0097] (1) Preparation of mixed plant essential oil:

[0098] Under microwave-ultrasonic and nitrogen atmosphere conditions, blueberry leaves and roses are extracted with a mixture of ethanol, ethylene glycol and acetone at a mass ratio of 1:1:1 to obtain mixed plant essential oils;

[0099] (2) Preparation of microcapsule plant essential oil nucleus:

[0100] Take 4g of soft-shelled turtle skin collagen and 2g of jinfu mushroom polysaccharide prepared above and dissolve them in distilled water at 40°C, and dissolve while stirring to make a saturated solution;

[0101] Add 9 g of the mixed plant essential oil of step (1) dropwise under stirring conditions, and emulsify to obtain a homogeneous mixed solution of soft-shelled turtle skin collagen, golden mushroom polysaccharide, and mixed plant essential oil;

[0102] Adjust the pH of the above-mentioned ...

Abstract

The invention discloses collagen / polysaccharide embedded microcapsule plant essential oil which comprises a compound wall material and a core material. The essential oil is characterized in that the core material is blueberry and rose mixed plant essential oil, the compound wall material wraps the outer side of the plant essential oil, the compound wall material comprises three layers including the first layer, the second layer and the third layer from inside to outside in sequence, the first layer is made of a turtle skin collagen and tricholorna lobayense polysaccharide crosslinking agent, the second layer is made of beta-cyclodextrin, and the third layer is made of a turtle skin collagen and tricholorna lobayense polysaccharide crosslinking agent. The mass ratio of the turtle skin collagen to tricholorna lobayense polysaccharides is 2:(1-2), the mass ratio of blueberry essential oil to rose plant essential oil is 1:2, and the mass ratio of the core material to the compound wall material is 1.5:1. The embedding rate is high, the volatilization of the essential oil can be prevented, the original properties and states of the plant essential oil are kept, the essential oil is easy to release in use, the storage life and shelf life of the essential oil can be greatly prolonged, and the quality of the essential oil is improved.

Description

technical field [0001] The invention belongs to the technical field of microcapsule plant essential oil embedding, and in particular relates to a collagen / polysaccharide-embedded microcapsule plant essential oil and a preparation method thereof. Background technique [0002] The composition of plant essential oils is very complex. According to the chemical structure, it can be divided into aliphatic, aromatic and terpenoid compounds and their oxygen-containing derivatives such as alcohols, aldehydes, ketones, acids, ethers, esters, lactones, etc. There are also nitrogen- and sulfur-containing compounds. Studies have found that plant essential oils have antioxidant, anti-inflammatory, and antibacterial effects. For example, plant essential oils extracted from blueberry leaves and blueberry flowers have special aromas, and their volatile oils have the effect of inhibiting various epidemic viruses. However, during the placement and processing of plant essential oils, some medi...
