Production process of pectin for probiotic coating

Abstract

The invention discloses a production process of pectin for probiotic coating, and relates to the technical field of pectin production. The method comprises the following steps: step 1, mixing fresh lemon peel with clear water in a container according to a ratio of 1: 5, cleaning the fresh lemon peel for 30 minutes, and repeating for 3 times; 2, stirring the cleaned lemon peel and clear water in a stirring tank according to a ratio of 1: 6, controlling the temperature at 75-84 DEG C, and adding 65% concentrated nitric acid according to 0.2% of the amount of the added clear water; 3, keeping the temperature at 80 DEG C, stirring for 2 hours, and adding ammonia water with the concentration of 23% to adjust the pH value to 3; and 4, separating the extract by using a plate-and-frame filter press, filtering the separated extract by using diatomite to remove residual insoluble particles, and carrying out vacuum concentration by using an experimental MVR evaporator until the pectin content is greater than 2.8%. The pectin produced by the process has the characteristics of low viscosity, good solubility and good probiotic coating performance by adopting an enzymatic viscosity reduction and composite granulation mode.

Description

technical field [0001] The invention belongs to the technical field of pectin production, and in particular relates to a pectin production process for coating probiotic bacteria. Background technique [0002] Pectin is a kind of high-molecular high-viscosity substance, which is difficult to dissolve in water, and it is often difficult to realize its function development. Therefore, there are various pectin production processes on the market; Pectin has high viscosity, poor solubility, and generally unsatisfactory encapsulation performance of probiotics. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a kind of pectin production technology for probiotics coating, to solve the existing problems: the pectin viscosity that the pectin production technology in the prior art is manufactured is higher, and the solubility is poor , and the coating performance of probiotics is generally not ideal. [0004] In order to solve the above-mentioned t...
