Application of Biotechnology in the Dairy Industry: A Review
Abstract
Biotechnology has become an important tool in the dairy industry by improving milk production, product quality, processing efficiency, and environmental sustainability. It has enabled the development of advanced starter cultures, microbial enzymes, probiotics, and genetically modified microorganisms that enhance the production of cheese, yogurt, fermented milk products, and other value-added dairy foods. Biotechnological approaches such as accelerated cheese ripening, designer milk production, and the development of functional dairy products have improved nutritional quality, shelf life, and consumer health benefits. In addition, biotechnology plays a significant role in the effective utilization of whey and dairy waste by converting them into valuable products, thereby reducing environmental pollution. Recent research has also demonstrated the potential of probiotic and prebiotic dairy products in improving human health and supporting specialized nutrition. Despite these advancements, challenges such as high production costs, biosafety concerns, ethical issues, regulatory requirements, and consumer acceptance continue to limit large-scale adoption. Overall, biotechnology offers tremendous opportunities for developing innovative, safe, and sustainable dairy products while supporting the future growth of the dairy industry.
