Formulation of sprouted cowpea yoghurt rich in antioxidant, as functional drink for diabetics

Abstract

This study aimed to obtain a formula of Cowpea sprouted yoghurt (Cops-Yo) rich in phenolic antioxidants, fibre, vitamin C, and protein based on Lactic Acids Bacteria (LAB) levels and the proportion of sprouted cowpea milk (Cops-milk) and skim milk. This factorial study used a completely randomized design (CRD), with a factor of LAB levels and the proportion of sprouted cowpea milk and skim milk. Cops-Yo product was obtained and tested for phenolic content (Folin Ciocialteau method), fibre (oven method), vitamin C (Iodometry), and soluble protein (Lowry method). Data was tested using ANOVA, followed by DMRT if there was significance at a 5% level. The best Cops-Yo formula was obtained from a proportion of 70 parts of sprouted cowpea milk and 30 parts of skim milk with 0.3% LAB. The product has characteristics that contain 529.75 mg GAE/L of phenolic, 3.09% dietary fibre, 100.55 mg/100 g vitamin C, and 36.22% soluble protein. The result reflects that Cops-Yo could help improve sugar levels in diabetic patients.
