摘要：The effect of different processing temperatures on some quality characteristics of soymilk was determined. Soybean was processed at varying temperatures (80, 90 and 110°C), to produce soymilk samples A, B and D, with product processed using the normal boiling temperature of 100°C (sample C) as standard. The soymilk products were subjected to physiochemical, microbiological and sensory analyses using standard analytical methods. The moisture and crude fat contents decreased significantly (p 3-2.3×103 CFU/mL, while yeast and mould count ranged from 0.3×102 to 1.2×102 CFU/mL, with the lowest values coming from the products processed at 110°C, thus making sample D microbiologically safer than the others. Mean sensory scores for colour and flavour ranged from 5.90 to 7.00 and 5.87 to 8.33, respectively. Though all the soy milk products were acceptable, milk processed at 100°C (sample C) had the highest acceptability score (8.33) followed by samples B (6.60), A (5.89) and D (5.87) in that order. Processing at 100°C gave the best product in terms of all the attributes measured and is therefore, recommended for soy milk processors.
