Three batches of processed cheese (PC) were manufactured by the standard procedure and packed aseptically in polystyrene (Sunpet) pet jars with screw cap of about 200 g capacity and stored at 5, 30 and, 45°C. The PC samples were analysed for proximate composition, selected physico-chemical characteristics and sensory attributes at intervals of 7 days for the product stored at 5°C upto 56 days, 3 days for the product stored at 30°C upto 6 days and 24 days at 45°C till the sample became organoleptically unacceptable. The results revealed that 30°C was conducive for mold growth, due to which the product …

Consumer interest in probiotic bifidobacteria is increasing, but industry efforts to secure high cell viability in foods is determined by these anaerobes’ sensitivity to oxidative stress. To address this limitation, we investigated genetic and physiological responses of two fully sequenced Bifidobacterium animalis subsp. lactis strains, BL-04 and DSM 10140, to hydrogen peroxide (H2O2) stress. Although the genome sequences for these strains are highly clonal, prior work showed they differ in both intrinsic and inducible H2O2 resistance. Transcriptome analysis of early stationary phase cells exposed to a sub-lethal H2O2 concentration detected …
