Packaging Defect Causes Odor in Aavin Milk, Safety Ensured

An official inquiry by the Madurai District Cooperative Milk Producers’ Union, known as Aavin, revealed that a chemical odor detected in 500ml Delite milk packets was caused by a packaging defect. This issue stemmed from a poly-film curing defect rather than the quality of the milk itself. The investigation was led by Assistant General Manager A. Muthukarthikeyan after consumers reported a chlorine-like odor.

Initial tests on the outer surface of the packaging failed to find the issue as the first 20 meters of the packaging rolls were deemed satisfactory. However, deeper layers of the tightly wound 30kg rolls contained trapped residual gases. A laboratory analysis identified the source of the odor as volatile organic compounds produced by an improper curing process during the poly-film manufacturing, along with issues in the dye application of the film.

In response to these findings, Aavin's management removed the affected poly-film rolls from their processing and packaging lines to prevent further distribution. They also issued a show-cause notice to the third-party vendor responsible for the packaging, demanding an explanation and warning of potential administrative action.

This incident highlights the importance of stringent quality control protocols in the supply chain, especially concerning food-grade flexible packaging materials. Aavin's swift action to replace the defective packaging and verify product safety through central lab testing helped maintain consumer trust and public health.
