The detection of oxygen using optical sensors is of increasing interest, especially in modified atmosphere food packaging (MAP), in which the package, usually containing food, is flushed with a gas, such as carbon dioxide or nitrogen. This tutorial review examines the ideal properties of an oxygen optical sensor for MAP and compares them with those developed to date, including the most recent advances. The basic technologies underpinning the different indicator types are described, examples…

Innovation of oxygen indicator for packaging leak detector: A review

Oxygen is one of the factors causing the food product damage. Therefore, vacuum packaging or modified atmosphere packaging (MAP) is an effective solution offered. However, there is always a risk of

Chromatic Sensor to Determine Oxygen Presence for Applications in Intelligent Packaging

A chromatic sensor has been designed for the detection of oxygen in package headspace based on the redox change of methylene blue to its leuco form and specific migration analysis showed no trace of migration thanks to the functional barrier included in the design.

THE USE OF OXYGEN INDICATORS - ELEMENTS OF INTELLIGENT PACKAGING FOR MONITORING OF FOOD QUALITY

Indicators for the detection of oxygen allows the consumer to provide some information on the suitability of the product for consumption and is a simple tool that allows you to reduce the costs associated with loss replacement, repair damaged pr oducts or their disposal.
