**13. Adding probiotic microencapsulation to food products**

Dairy products have traditionally been the best producer of probiotics. They showed excellent conditions for the survival of probiotic bacteria. Because milk has a physicochemical composition rich in protein and with a significant amount of lipids. As a result, it creates a protective matrix for probiotics [23]. Microencapsulation is important to increase probiotic The addition of bead should not affect the sensory properties of food products. The addition of bead should not affect the sensory properties of food products [63]. Most of the research has been done and the products that are marketed in the food industry as probiotics. Dairy products are probiotics. Due to the problems of lactose intolerance in some people in the community (about 70% in Asia), sensitivity to milk proteins and the prevalence of high cholesterol require foods other than dairy that are good carriers for probiotic bacteria. Non-dairy foods provide a variety of substrates of antioxidants, dietary fiber, minerals, and vitamins [23]. The development of non-dairy probiotic products such as fruits, vegetables and grains has been shown to be one of the best choices and has increased the demand for non-dairy probiotics [23]. Properties and structural compounds (nutrients such as minerals, vitamins, dietary fiber and antioxidants, including the right amount of sugar) Fruits, vegetables and grains are suitable and ideal substrates for probiotic microbes [67]. Various factors such as protein concentration, sugar, fat and pH level in the food product can affect the growth and survival of probiotics [63].

### **14. Release of probiotic bacteria from microencapsulation**

Scientific sources related to the probiotic microencapsulation emphasize on its destruction, in the large intestine. The microencapsulated bacteria can resist acidic conditions in the stomach. Depending on the processing conditions and the type of coated material used, it regulates the release rate of microencapsulation bacteria in the presence of bile salts [5]. In this way, probiotic bacteria are protected and as a result, high concentrations of living cells can be achieved [5]. The finely coated must have selective permeability to support the environmental conditions that keep cells live, so that it can be designed to release probiotic cells in a specific area of the body [5].
