Abstract: This paper studied the lactic acid bacteria cell immobilized on sodium alginate and its effect on accelerating ripening of cheese. Results from starter lactic acid bacteria cell immobilized with sodium alginate showed that WSN, TCASN and PTASN increase steadily as the ripening period advanced for all cheese treatments. The cheese contains 106CFU/g immobilized lactic acid bacteria with more pronounced amounts of water soluble nitrogen (WSN), trichloroacetic acid soluble nitrogen (TCASN) and phosphotungstic acid soluble nitrogen (PTASN) than the control batch. During early ripening, the acid value(ADV) of cheese varies little, while increases obviously after 45 days. This may be due to the slow release process of immobilized lactic acid bacteria during ripening. Results from organopleptic evaluation showed that cheese contained 105CFU/g immobilized lactic acid bacteria develops a strong flavor with firm texture after 60 days ripening, the ripening time shortened about 30 days.
