dc.description.abstractCasein hydrolysates (CNH) - mineral complexes are a promising strategy for enhancement of mineral absorption & reduction of mineral deficiency. CNH have wide range of activities including cholesterol-lowering ability, antithrombotic and antioxidant activities, enhancement of mineral absorption/bioavailability and opioid activities. In the present investigation, an attempt was made to develop CNH-Zn complex incorporated biscuit and cupcake and in-vitro bioavailability of the zinc from the biscuit and cupcake was explored. Among the various enzyme substrate used for the hydrolysis, the highest degree of hydrolysis was obtained for 1:25 enzyme substrate ratio for 120 min and 700 mg added zinc showed highest zinc binding among all. Biscuit and cupcake prepared by incorporating CNH-Zn complex solution showed moisture, protein, fat, carbohydrates, ash and peroxide value of 4.23, 7.58, 24.53, 0.97, 65.68 per cent and 2.10 meq O2/kg fat, respectively for biscuit and 16.00, 12.36, 26.05, 1.83, 43.75 per cent and 2.53 meq O2/kg fat, respectively for cupcake. Experimental biscuit and cupcake samples tested for invitro bio-availability of zinc showed 52.93 and 63.43 per cent, respectively. Storage studies at ambient temperature revealed that biscuit sample retained acceptability up to 45 days and cupcake sample retained acceptability up to 6 days. Moisture and peroxide values increased during storage in both biscuit and cupcake samples. Total viable counts and yeast and mould counts increased during storage in both biscuit and cupcake samples whereas coliform counts were nil throughout the storage.
