The use of LIBS technology, as explained by Dr. Raja Kamarulzaman Raja Ibrahim, holds significant potential in the food industry, including detecting haram elements, such as pork, and identifying the elemental composition in food products like meatballs. LIBS works by focusing a high-energy laser on the sample surface, creating plasma that ionizes the elements contained within the sample. It can detect specific elements in pork or alcohol in beverages. This technology is fast, non-destructive to the sample, and suitable for large-scale testing in the food industry.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The application of LIBS is also highly relevant in detecting heavy metals and analyzing nutritional content in meatballs, including minerals like calcium, magnesium, sodium, and phosphorus. LIBS can ensure product quality and composition, safeguarding safety and compliance with established standards.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
