This study was conducted to evaluate the effect microencapsulated methods using sodium alginate, -carrageenan, skim milk and whey protein on the production of some important compounds (exopolysaccharides, acetaldehyde, diacetyl and vitamin B12) using microencapsulated probiotic strains. Also, the suitbale incubation period, temperature degree, pH value and growth medium for maximum production of important compounds with microencapsulated strains was studied. Microencapsulated strains with sodium alginate gave the greatest production of exopolysaccharides at 37 ºC for 18h, pH 5.5 and Elliker+5...

Microencapsulated strains with sodium alginate gave the greatest production of exopolysaccharides at 37 ºC for 18h, pH 5.5 and Elliker+5%sucrose growth medium using microencapsulated Lactobacillus bulgaricus. The greatest production of acetaldehyde and diacetyl was achieved using 25 ºC for 24h, pH 6 and Elliker growth medium using microencapsulated Leuconostoc mesenteroides. The greatest production of vitamin B12 was recorded using microencapsulated Propionibacterium shermanii and sodium lactate medium at 30 ºC for 36h underanaerobic condition and pH 6. Kareish cheese, stirred yoghurt and Tallaga cheese were manufactured which inoculated with encapsulated strains using sodium alginate and the finished products.
