Abstract

ABSTRACT The objective of this study was to characterize the durian lay juices supplemented by Lactic Acid Bacteria (LAB) culture during cold storage. The LAB cultures consisted of Lactobacillus plantarum FNCC-0265, Lactobacillus acidophillus FNCC-0051 and combination of these LABs. After being inoculated with a 24 h – old culture starters, durian lay juice was incubated at 37 °C for 2 hours and kept at 4 °C for 0, 1, 2, 3 and 4 weeks. Changes in pH, total lactic acid, and sugar content, viable cell counts of LAB, total soluble solid, viability of LAB, and sensory characteristic during fermentation were measured. The results revealed that pH decreased from 4.79 to 4.20; sugar content reduced from 4.52 to 0.75 %; total soluble solid reduced from 8.93 to 7.97 °Bx, and sensory score reduced from 3.71 (like) to 3.40 (moderate like); while the total lactic acid increased from 0.33 to 0.69 %; viable cell counts of LAB increased from 8.86 to 9.14 log CFU/ml; and % viability of LAB decreased from 100 to 95.90, during storage. Combination of Lactobacillus plantarum FNCC-0265 and Lactobacillus acidophillus FNCC-0051 cultures at two weeks cold storage period was the best treatment, based on the sensory and viable cell counts of LAB. The characteristics of this durian lay juice probiotic were pH 4.46, total lactic acid 0.59 %, sugar content 2.13 %, viable cell counts of LAB 9.33 log CFU/ mL, total soluble solid 9.60 °Bx, and carbohydrate 45,05 %. This durian lay juice contained oxalate (107.56 mg/L), malic (527.895 mg/L), lactic (4381.49 mg/L) and citric (351.245 mg/L) acid. Keywords: Durian lay; lactic acid bacteria; lactic beverage
