Abstract

The invention discloses probiotic embedded particles prepared from the following raw materials: probiotic powder, whey protein concentrate, sodium caseinate, Plantago ovata seed powder, polyfructose,resistant dextrin and phospholipid. The invention also provides a method for preparing the probiotic embedded particles, which comprises the following steps: (1) by using probiotic powder as a core material, carrying out fluidized bed spray embedding by using whey protein concentrate, sodium caseinate, Plantago ovata seed powder and water to obtain protein colloid protective layers, and drying toobtain embedded substance A; and (2) carrying out fluidized bed spray embedding on the embedding material A with polyfructose, resistant dextrin, phospholipid and water to obtain polysaccharide protective layers, and drying to obtain the probiotic particles. The advantages are that the probiotic powder protected by the protein colloid protective layers and the polysaccharide protective layers areobtained, are provided with the characteristics of high acid resistance, high fluidity and high dispersion, can be preserved at room temperature, are stable in shelf life and are suitable for development and use of various products.

Description

technical field [0001] The invention belongs to the technical field of food, and specifically relates to a probiotic-embedded granule and a preparation method thereof. Background technique [0002] In 2001, FAO and WHO defined probiotics as "live microorganisms, live bacteria that have a beneficial effect on the host's health when ingested in an appropriate amount." Over the years, studies have also found that "live" probiotics are not limited to intestinal health. It also involves immune health and brain health. Therefore, the stability of probiotics in probiotic products is very important, and the ability of probiotics to reach the intestinal tract is also very important. The factors that affect the stability of probiotics during storage are mainly product properties (water activity, moisture content, oxygen content, pH, etc.) and product storage conditions (temperature, humidity, light, etc.). It is controlled by simple technical means, but the control of its product at...
