Abstract
Disclosed are emulsion gel with both a freshness indication and a low migration rate, and a preparation method therefor. Lipase and organic acid are used and subjected to hydrophobic modification of anthocyanins to obtain acylated anthocyanins, the acylated anthocyanins and oil-phase gel are then dissolved in vegetable oil to form an oil phase, while a sodium alginate aqueous solution is used as a water phase, the oil phase and the water phase are mixed and subjected to high-speed shearing, and calcium carbonate and glucono-δ-lactone are finally added for high-speed shearing to form emulsion gel. The emulsion gel prepared in the present disclosure has both a freshness indication and a low migration rate, and the preparation method of the present disclosure is simple, green, pollution-free and low energy consumption.
