Problems solved by technology

However, in the process of microcapsule preparation, without the action of oxidant, Ganoderma lucidum spore oil will rapidly oxidize and deteriorate in the air, and then lose its activity, and the surface of microcapsules obtained by spraying protein isolate and maltodextrin as wall materials will be damaged. There are a lot of exposed core materials, causing the exposed core materials to oxidize and waste raw materials
[0009] Although the above-mentioned patent applications and documents have improved the stability of Ganoderma lucidum spore oil to varying degrees, the antioxidant properties of Ganoderma lucidum spore oil have not been significantly improved, making the stability of Ganoderma lucidum spore oil products not high, which ultimately limits the development of the Ganoderma lucidum spore oil.

Embodiment 1

[0046] Dissolve 6g of ε-PL-TOS amide complex and 8g of gum arabic in 400mL of 50°C water respectively to prepare a solution of ε-PL-TOS amide complex and gum arabic, cool to 40°C for later use. At 40°C, add 9.0 mg of Ganoderma lucidum spore oil to the above 400 mL of 1.5% ε-PL-TOS amide complex solution by mass, and shear and emulsify at 10,000 rpm for 5 min; then add 400 mL of 2% gum arabic solution, Disperse at 22000rpm for 15min to obtain a stable emulsion. Vacuum the emulsion to a relative vacuum of 0.09Mpa, keep it for 10min, then add dropwise acetic acid with a mass fraction of 5% under stirring to adjust the pH value of the emulsion to 4.6, continue stirring for 10min, cool down to 4°C, and precipitate Microcapsules; add dropwise NaOH with a mass fraction of 10% to adjust the pH to 6.5, add 160 U of transglutaminase, and stir at 4°C for 10 hours to solidify the microcapsules to obtain a mixed system. The mixed system was refrigerated and centrifuged at 15,000 rpm at 4°...

Abstract

The invention discloses a composite microcapsule wall material, microcapsules and a preparation method of the microcapsules. The composite microcapsule wall material consists of colloid with positive charges and colloid with negative charges, wherein the colloid with positive charges refers to an epsilon-polylysine-vitamin E succinate amide complex. The epsilon-polylysine-vitamin E succinate amide complex serves as one component in the composite microcapsule wall material, and according to the prepared microcapsules, the stability and oxidization resistance of the core material can be obviously improved, so that the core material is difficult to deteriorate, and the quality guarantee period is prolonged.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a composite microcapsule wall material, microcapsules and a preparation method. Background technique [0002] Ganoderma lucidum is the general name of red lucidum and purple lucidum, a fungus of the genus Ganoderma lucidum of the basidiomycete family Polyporaceae. It has the effect of benefiting Liver Qi and benefiting Spleen Qi. Ganoderma lucidum spores are extremely small spores ejected from the cap during the mature growth period of Ganoderma lucidum. They are the germ cells of Ganoderma lucidum and have all the genetically active substances of Ganoderma lucidum. Their medicinal value has attracted increasing attention and has become a research and development focus. [0003] Ganoderma lucidum spore oil is a lipid active substance extracted from broken Ganoderma lucidum spores, usually only 1g of Ganoderma lucidum spore oil can be extracted from 20g of Ganoderma lucidum spore p...
