A method for preparing a food grade natural adhesive based on honey

Abstract

The application discloses a preparation method of a food-grade natural adhesive based on honey, and relates to the technical field of adhesive preparation.The preparation method comprises the following steps: pretreating honey raw materials, adjusting the mass ratio of glucose to fructose in the honey to 1.2:1-1.4:1, adding food-grade microcrystalline cellulose as a heterogeneous crystal nucleus, and adding inulic acid as a crystal form regulator; cooling the mixture to 14±0.5 DEG C, and applying ultrasonic treatment in the cooling process to induce glucose to be preferentially precipitated in the form of needle-shaped crystals and form a crystal interpenetrating network; and then performing temperature rising to terminate crystallization, homogenization treatment, vacuum degassing, sterile filling and sealing, so that the food-grade natural adhesive is obtained.The application can actively control the crystallization behavior of honey by adjusting the ratio of glucose to fructose in the honey and introducing microcrystalline cellulose as a heterogeneous crystal nucleus and inulic acid as a crystal form regulator, so that a stable semi-solid paste formed by the interpenetration of needle-shaped glucose crystals and microcrystalline cellulose is formed.
