An intelligent substance or item must be able to convey information about how packed goods have changed over time—whether it's the loss of packing integrity or the ripening stage of packaged fruits, or whether harmful microbes are present (also known as analytes or irritants).
In order to design intelligent systems that best satisfy the needed functions, such as giving information on packaging integrity, safety or packaged food quality, the following graphic illustrates the many components to be taken into account. Determine the indicators to monitor throughout the life cycle of packaged food in order to achieve this goal. These may be connected to the food's surroundings, such as the amount of time it spends at a given temperature (time / temperature), or even the gas content in the headspace. if you're in this situation
Intuitive packing classification
Depending on whether the packaging changes or the environment changes, intelligent packaging may be classified into two categories: direct and indirect indicators of food quality.
Classify smart based on the information that will be made available to the consumer.
indications of the quality of packaging products
Despite this, in today's market, time-temperature indicators rule. In order for them to be effective, they must have reaction kinetics that match the planned use. The temperature's impact on these processes must be proportional to its own.
Moreover, these dynamics must be measured in terms of the deteriorating time of packaged food. As you can see, most of these indications are based on visible changes in color. The business examples given in the graphic below illustrate the wide range of responses that might occur.
Color-coded representations of several types of clocks and thermometers
® The previously mentioned checkpoint When enzymatic hydrolysis is used to break down food, it alters the development and pH of the microorganisms (chosen for the target food) that are present, leading to color change. Colorful polymerization and migration of blue ester (butyl stearate, dimethyl phthalate, etc.) can be achieved through the temporary time company and the 3M monitormarktm, which can vary flow time depending on temperature (relative to the melting temperature of the selected ester) and the time of 3M monitormarktm.
