Abstract
In response to population growth, ethical considerations, and the environmental impacts of animal proteins, researchers are intensifying efforts to find alternative protein sources that replicate the functionality and nutritional profile of animal proteins. In this regard, plant-based cheese alternatives are becoming increasingly common in the marketplace, as one of the emerging dairy-free products. However, the dairy industry faces challenges in developing dairy-free products alternatives that meet the demands of customers with specific lifestyles or diets, ensure sustainability, and retain traditional customers. These challenges include food neophobia, the need to mimic the physicochemical, sensory, functional, and nutritional properties of dairy products, the inefficient conversion factor of plant-based proteins into animal proteins, and high production expenses. Given the distinct nature of plant-based milks, understanding their differences from cow’s milk is crucial for formulating alternatives with comparable properties. Designing dairy-free cheese analogs requires overcoming electrostatic repulsion energy barriers among plant proteins to induce gelation and curd formation. Innovative approaches have substantially enhanced the physicochemical and sensory properties of these alternatives. Researchers are exploring the application of microalgae as a plant protein source and investigating new microbial fermentation methods to increase protein content in dairy-free products.
