Abstract
The study investigated the physico-chemical and storage qualities of “Awara” produced from soymilk with tamarind (Tamarindus indica L.) fruit pulp extract as coagulant. The experimental design was 5 x 6 completely randomized design. The “awara” products were prepared using coagulant at 4%, 6%, 8%, 10% and 12% vol. concentrations and heated in appropriate volume of soymilk (12litres) to obtain “awara” products designated sample B, C, D, E and F respectively. Control sample A was prepared from reconstituted skimmed milk powder with 4% coagulant. For storage studies, ambient stored samples were analyzed at 0 day and 1 week intervals. All samples were subjected to standard analytical methods. Results showed that the percentage yield of awara products ranged from 7.89-20.29% with control sample A having the highest value of 20.29% while sample B had least value (7.89%). The range of textural parameters was 0.74-65.71 representing the minimum and maximum values of elasticity and hardness respectively. In hardness, F (65.71%) with the highest value is significantly different to all the samples and each sample is significantly different to the other at (P = .05). Total Titratable acidity values ranged between 0.059-1.53% representing B and D respectively. pH value ranged from 4.4-6.6 in day 0 and 2.7-4.1 in week 1 with A having highest value both in day 0 and week 1. There was a decrease in total bacteria and fungi counts in day 0 with increased addition of coagulant. The result of the microbiological showed that the awara samples cannot keep more than one day.
