Description Ph.D. Thesis
In this investigation, ready to use functional weaning food was developed by
using malted ragi, malted wheat, malted green gram, oil, sugar, whey protein
hydrolysates, and probiotics. The probiotics Lactobacillus acidophilus NCFM LYO 10D
and Bifidobacterium bifidum NCDC 232 were propagated in cheese whey medium
enriched with various prebiotics. A maximum viable count could be attained at 1.5 per
cent inoculum at an incubation period of 15 h with the enrichment of 2 per cent honey, 4
per cent carrot and tomato juice (1:1) and 1.5 per cent whey protein hydrolysates (WPH).
Amongst 3 enzymes tried for hydrolysis of whey proteins, Neutrase was found to be
superior. Enzymatic hydrolysis of WPC at 1:50 enzyme to substrate ratio resulted in
maximum hydrolysis. The weaning food was optimized for replacement of wheat malt
with ragimalt, green gram malt with WPC and WPH at 50, 30 and 20 per cent
respectively. Spray drying formulated weaning food blended with 5 per cent probiotics at
70oC feed temperature and 70oC outlet temperature was optimum, which resulted in
viable probiotic counts of 4 log cfu/g. Whereas blending probiotics at 5 per cent to the
spray dried weaning food followed by fluid bed drying at 45 oC outlet air temperature
resulted in viable counts of more than 8 log cfu/g in case of both probiotics. Bioassay
studies revealed that functional weaning food developed in this study had higher PER,
FER, DC, BV and NPU, respective values being 3.19, 0.38, 95.68, 85.25 and 81.56, as
compared to the control which had respective values of 2.10, 0.25, 85.85, 71.45 and
61.33. Weaning food packaged in PET under MAP (20:80 C02 & N2) was found to be
better as compared HDPE and packaging under normal atmospheric packaging as
evaluated in terms of PV, FFA, HMF and viable counts of probiotics. At this
combination, the viable counts of both the probiotics were more than 6.5 log cfu/g even
after 6 months of storage.
