Abstract
The escalating environmental and health concerns regarding conventional meat consumption have intensified the global search for sustainable dietary alternatives. Plant-based foods and meat substitutes have emerged as promising solutions. These products aim to replicate the sensory and nutritional attributes of meat while mitigating ecological impacts. This review examined the current scenario of plant-based foods and meat substitutes, focusing on their environmental footprints, health implications, innovative ingredient developments, consumer acceptance, and the use of analytical tools in quality control. Life cycle assessments indicate that plant-based foods and meat substitutes significantly reduce greenhouse gas emissions, land use, and water consumption compared to animal-based products. These alternatives offer benefits like lower saturated fat. However, they still struggle to match the amino acid composition of meat. Consumer acceptance is influenced by factors including taste, texture, and cultural perceptions, and still requires sensory improvement. Innovations in ingredient sourcing, like the use of legumes, mycoproteins, and fermentation-derived components, are enhancing product quality and diversity. Furthermore, analytical tools such as electronic noses, electronic tongues, spectroscopy, and chemometric methods ensure product consistency and fulfill consumer expectations. By synthesizing interdisciplinary insights, this review offers an integrated perspective to guide future research and development in the field of meat alternatives.
