Enhancing Yogurt Functionality through Enrichment with Cow and Soy Milk: Production and Quality Evaluation

Abstract

Yoghurt is a fermented dairy product produced from cow’s milk. Soybeans are abundant, reasonably priced, and high in protein, so there has been some work done to use them to make more pleasant and acceptable food products. Although many people eat cow's milk yoghurt, others who are lactose intolerant or follow a plant-based diet could find it incompatible. However, in comparison to regular yoghurt, soy milk yoghurt does not always live up to customer expectations regarding flavor and texture, even though it is nutritionally sound. The difficult part of making yoghurt is creating a recipe that combines the health advantages of soy milk with the desired sensory attributes of cow milk yoghurt. In the current investigation, soy milk was added to the milk of cows. The final soybean yoghurt was assessed about post-acidification modifications. The primary aim of this research is to improve the nutritional value and functioning of yoghurt by the addition of a blend of soy and cow's milk. In keeping in mind yogurt is made out of cow milk and soy milk. Cow milk is rich in protein, calcium, vitamin D, and Potassium. Soy milk is rich in vitamins A, B, and proteins. The yogurt made out of this may have various health benefits. The study blended cow and soy milk in various proportions to create different yogurt formulations. The treatments were as follows: T1: Soy milk (200 ml) without cow milk, T2: Cow milk (200 ml) without soy milk, T3: [Cow milk (100 ml) + Soy milk (100 ml)], T4: [Cow milk (120 ml) + Soy milk (80 ml)], T5: [Cow milk (80 ml) + Soy milk (120 ml)], T6: [Cow milk (160 ml) + Soy milk (40 ml)], and T7: [Cow milk (40 ml) + Soy milk (160 ml)]. These formulations were tested to achieve a high-quality blended yogurt that is both nutritious and flavorful. Combining soy and cow's milk to enhance yoghurt is a viable way to satisfy the nutritional requirements of a wider range of customers, including those who have lactose intolerances or who choose plant-based diets. According to the study's findings, soy milk-enriched yoghurt is a competitive and enticing product on the market since it maintains the good aspects of regular yoghurt while also offering increased nutritional value. Optimising the ratio of cow to soy milk and gauging long-term customer acceptability are two potential areas for future study.
