AI Technical Summary

Technical Problem

Existing technologies cannot effectively solve the problems of layering and sedimentation, prominent fishy and goaty odor, low digestibility and utilization rate, and insufficient functional activity in donkey milk beverages, making it difficult to achieve high-value-added industrial development of donkey milk resources.

Method used

A synbiotic fermentation system was constructed using compound prebiotics and multi-strain probiotics. Fermented donkey milk beverages were prepared by combining two homogenization processes. Long- and short-chain prebiotics synergistically provide carbon sources for probiotics, promote strain proliferation and metabolism, optimize gel structure, and decompose fishy and goaty odors through multi-strain synergistic metabolism, thereby improving digestibility and antioxidant function.

Benefits of technology

It significantly improves the system stability, sensory flavor, and antioxidant activity of donkey milk beverages, solves the problems of layering and sedimentation and fishy and pungent odor in donkey milk beverages, improves the digestibility and functionality of the product, and is suitable for large-scale mass production.

Abstract

The application relates to the field of food processing and discloses a synbiotic fermented donkey milk beverage and a preparation method thereof. The method takes freeze-dried donkey milk powder as raw material, adds water to a mass fraction of 12% for re-dissolution, adds a compound probiotic accounting for 4% of the total mass of the donkey milk liquid, uniformly mixes, homogenizes at 20 MPa for 40 s, sterilizes at 95 DEG C for 10 min, inoculates 3% mixed probiotic powder after the material liquid is cooled to 42 DEG C, and ferments at 42 DEG C for 7 h to obtain a fermented milk base. The base is diluted with distilled water at a mass ratio of 1:3, 6% sucrose and 0.4% food stabilizer are added and uniformly mixed, the mixture is subjected to secondary homogenization at 20 MPa and secondary sterilization at 95 DEG C for 15 min, and then the mixture is cooled to room temperature to obtain the synbiotic fermented donkey milk beverage. The application solves the problems of easy stratification and sedimentation, prominent fishy and rancid odor of natural donkey milk in the prior art, simultaneously makes up for the defects of low digestion utilization rate and insufficient functional activity of the product, and improves the high added-value industrial utilization level of donkey milk resources.
