Effect of Analogue Milk Enrichment with Whole Soy Bean Flour

Abstract

The potential of milk enrichment with soybean flour was studied .Yoghourt control Sample A: 100% Milk powder (Dano)and o% wholes soyabean flour, Sample B: 90% fermented milk powder (Dano) and 10% whole soybean flour, Sample C: 80% fermented milk powder (Dano) and 20% whole soybean flour, Sample D: 70% fermented milk powder (Dano) and 30% whole soybean flour, Sample E: 60% fermented milk powder (Dano) and 40% whole soy bean flour were produced respectively. The proximate composition, physio-chemical properties and sensory evaluation were determined using standard methods .The results on proximate obtained showed increase in values for moisture (77.79- 89.34) %, protein (3.06-9.23) % , fat content (1.57-3.97)% and fibre content (0.18-2.45)%. However, reversed trend was observed for ash and carbohydrate values respectively. The physiochemical analysis results obtained showed decrease in total solids (22.21-10.66)%, total solid non-fat (201.64-6.70)%, TTA (1.34-0.78)%, viscosity (10.54-0.86)Pa.s and PHwith had increased values from (4.5-5.13). The sensory evaluation result revealed that there were no significant difference p>0.05 between the control and sample B in appearance but there were significance difference p<0.05 between the control and the enriched sample in terms of aroma, taste, mouthful and overall acceptability. It was observed that substituting 10% whole soybean flour with powdered milk gave a symbiotic yoghurt ranked physico –chemical and sensory characteristics values as the control yoghurts sample.
