Abstract
To ensure food security amid dwindling natural resources, alternative proteins (APs) have been suggested as a sustainable solution. Yet, the adoption and consumption of APs remain limited. This review aims to delve into the latest progress (following PRISMA guidelines) concerning the utilization of proteins from alternative sources, particularly focusing on their effective incorporation into food products. Our findings reveal that insect proteins can improve amino acid profiles in bakery products. However, consumer acceptance remains low due to cultural biases, with optimal sensory results being achieved at lower substitution levels (5–10%). Mushroom proteins, when incorporated into meat analogs and bakery items, enhance nutritional value and offer favorable sensory properties, making them viable replacements in meat products. Plant-based proteins, such as pea and soy proteins, increase fiber and antioxidants and improve texture in meat alternatives, although formulation adjustments are necessary to meet consumer expectations for taste and overall experience. Microalgae offer unique benefits for bakery, confectionery, and dairy products by boosting protein, fatty acids, and probiotic growth while maintaining sensory acceptability. In conclusion, this study highlights that the effective incorporation of APs into food products can help in the development of healthier, more sustainable diets. That said, the success of AP acceptance will depend on continued innovations in formulation and consumer education.
