Growth of Bifidobacterium lactis BB-12 in reconstituted baby cereal flakes enriched with inulin

There is growing interest in including probiotics and prebiotics in dietetic products for children. The aim of this study was to assess growth of probiotic strain Bifidobacterium lactis BB-12 in reconstituted wheat grits baby cereal flakes. Samples were prepared by adding lyophilised culture of Bifidobacterium lactis BB-12 to dehydrated wheat grits baby cereal flakes (with and without inulin), and then hydrated with pasteurized milk (3, 2% fat) at two different temperatures (22º C and 50º C). Samples were stored at 6, 22 and 35º C and were analyzed by plating on MRS agar in anaerobic conditions after 3, 6, 12 and 24 h of storage. The initial number of probiotic strain Bifidobacterium lactis BB-12 has been 4.3 . 106 cfu/ml of reconstituted baby cereal flakes. There was no change in number of bifidobacteria in any of hydrated cereal flakes stored at 6º C for 24 h. Samples stored at 22 and 35º C have shown an increase of bifidobacteria population. The highest growth of Bifidobacterium lactis BB-12 was achieved in samples enriched with inulin and stored at 35º C for 24 h.
