Modelling prediction of gas release to improve quality of foods during low temperature storage

Modified atmosphere packaging (MAP) is widely used to reduce economic losses by extending the shelf-life of food products. This study aimed to develop an active MAP formulation component with sodium ascorbate, sodium carbonate, and ferrous sulfate, which was shown to be applicable at low temperatures (4 °C) while efficiently controlling O 2 and producing 1.0 %–44.1 % CO 2 . Moreover, the predicted equations enabled the estimation of the O 2 and CO 2 contents. In the future, the dosage could be determined based on the gas content required for various applications in food, such as refrigerated fruits, vegetables, and meats. Currently, the active MCP formulation for the reaction proceeds smoothly at 5 °C. Despite its promise, it requires additional water, making it inconvenient. However, these findings provide new insights into how active MAP facilitates convenient and effective development. • The customizable MAP system is based on gas requirements. • The active MAP system could be used at low temperatures. • The active MAP system provides O 2 and produces CO 2 at low temperatures without toxicity. • A wide range of atmosphere production is necessary for low-temperature storage of fresh food. • The reaction equation enables the dose required to be estimated based on the requirements.
