Food safety and quality are of utmost importance for consumers, suppliers, and regulators. The methodologies for determining the food quality are majorly classified as destructive and non-destructive techniques. The destructive techniques used for determining the food quality are labor-intensive, time-consuming, cost-intensive, and biased, while non-destructive techniques are gaining popularity due to ease of operation, reliability, and real-time results. Non-destructive methods play an important role in food industries due to its inherent nature. Both external and internal quality can be determined by non-destructive methods and rapidly help in sorting the superior quality of food products. Currently, different non-destructive methods such as electromagnetic, optical, mechanical, and dynamic are gaining popularity due to ease of operation, reliability, and faster turnover. The major drawback of non-destructive methods is the high equipment cost and the use of various instruments to analyze various parameters. But even then, these methods help to ensure customer satisfaction of products as it helps in providing good quality products without rupturing it.
