A scientifically based assessment of the secondary shelf life (SSL) might help reducing food waste generation at the household level. The present study addressed the SSL of two UHT milk brands upon simulated domestic use and storage after the first opening. Microbiological, sensory and physico-chemical parameters were monitored during 16 days of domestic storage to determine the period after opening during which UHT milk is still suitable for consumption. According to specific microbial and sensory acceptability limits, results showed that UHT milk is suitable for consumption until 6–7 days after first opening, even when managed in the worst conditions. The SSL of UHT milk may be extended from the current 3–4 days to 6–7 days, according to a precautionary approach. The reassessment of the labeled SSL of staple foods, such as milk, will contribute to reduce domestic food wastes, to increase sustainability of the food industry and competitiveness of food companies.

Abstract

A scientifically based assessment of the secondary shelf life (SSL) might help reducing food waste generation at the household level. The present study addressed the SSL of two UHT milk brands upon simulated domestic use and storage after the first opening. Microbiological, sensory and physico-chemical parameters were monitored during 16 days of domestic storage to determine the period after opening during which UHT milk is still suitable for consumption. According to specific microbial and sensory acceptability limits, results showed that UHT milk is suitable for consumption until 6–7 days after first opening, even when managed in the worst conditions. The SSL of UHT milk may be extended from the current 3–4 days to 6–7 days, according to a precautionary approach. The reassessment of the labeled SSL of staple foods, such as milk, will contribute to reduce domestic food wastes, to increase sustainability of the food industry and competitiveness of food companies.
