摘要

Lactobacillus plantarum HL-15 is able to inhibit the growth of mycotoxin producing fungi.To support the application of that culture,the research aimed to produce dried L.plantarum HL-15 and observe its stability during storage was conducted.Production of dried culture was started by fermentation of L.plantarum HL-15 then centrifuged to get the pellet.The pellet was mixed with filler(rice flour or tapioca)with a ratio 1:1(pellet:filler(10%),v/v)then dried.The temperature of the inlet and outlet of the spray dryer used were 105°C and 65°C,respectively.Dried culture was packaged in aluminum foil and sealed then stored at 4°C.Results showed that viable cells of dried inoculum with rice flour filler was 11.99±0.01 log CFU/g and dried inoculum with tapioca filler was 11.90±0.04 log CFU/g.Spray dried L.Plantarum HL-15 was proved being able to inhibit the growth of Aspergillus niger.During six months storage,there is a decrease in the viability of spray dried L.plantarum HL-15 either with rice flour or tapioca filler.During four months of storage,there was a decrease in the activity of inhibition of spray dried culture of L.plantarum HL-15 both with fillers of rice flour and tapioca to the growth of A.niger.L.plantarum HL-15 spray dried cultures could be stored at 4°C for four months for tapioca and five months for rice flour as filler.L.plantarum HL-15 spray dried cultures could inhibit the growth of A.niger so it could be used as a culture for inhibiting the growth of mycotoxin producing fungi in food.
