Abstract

The invention provides a garlic oil microcapsule with a shell made of soybean protein isolate and chitosan and a preparation method and application thereof. The preparation method includes making the soybean protein isolate, the chitosan and garlic oil into uniform emulsion; adjusting pH of the emulsion to 6.5, mixing to obtain microcapsule suspension, adjusting pH again to 6.0, adding glutamine transaminase, mixing to solidify the microcapsule, washing to collect wet microcapsule, and vacuum-freezing and drying to obtain the solid microcapsule, wherein mass ratio of the soybean protein isolate and the chitosan is 4:1 and mass ratio of a core and the shell is 1:1-1:4. The garlic oil microcapsule is obtained by electrostatic mutual attraction for the chitosan and the soybean protein isolate and embedding of the garlic oil, and accordingly pungent smell of the garlic oil can be covered, loss of diallyl sulfides in the garlic oil can also be avoided in food processing, and stability of the garlic oil is improved. Application of the garlic oil to the food industry is broadened.

Description

technical field

[0001] The invention belongs to the technical field of microcapsules, and in particular relates to a garlic oil microcapsule with soybean protein isolate and chitosan as wall materials, a preparation method and application thereof. Background technique

[0002] Garlic is a kind of spice that is loved by people, and it has been widely used in food such as seasonings and meat products. The main flavor components of garlic are sulfur-containing compounds, which are unstable to heat and are easily decomposed during processing, causing garlic to lose its original pungent taste. Garlic oil is an active ingredient extracted from garlic. In addition to the pungent taste of garlic, it also has antibacterial and anti-inflammatory effects, improves immunity, prevents cardiovascular system diseases, prevents cancer and anti-aging and other effects. Because the solubility of garlic oil in water is very low, and it has a special pungent and spicy taste, in addition, the m...
