Environmental chambers are an important research tool for food photostability. Experimental photomethodes have been developed to simulate the effect of aging food on the quality of its nutrients and organoleptic characteristics. Different types of aging chambers have been established, which can be atmospheric, airtight or oxidative.
And Kalstein can contribute with the new experimental methods for food safety and quality control by means of appropriate equipment for such measures, they apply to plant seed germination, planting, bacteria, microbes, animal and insect feeding, product quality testing and other light uses, constant temperature experiments. It is an ideal environment test equipment for biology, medicine, agriculture and livestock, forestry, research departments in environmental sciences.Therefore, the industrialization of food and food packaging has contributed to increasing the problem of food photostability. The use of environmental cameras allows to study the effect of light on food and the development of new photomethodes for the control of products.
Mechanisms of Environmental Chambers
Environmental camera technology has allowed scientists to get better images of places and objects. These cameras control processes when the chemical composition of components is altered due to the action of light. Although this process is natural, it has accelerated in recent times due to changes in the consumption habits of the population and the industrialization of food. Exposure to sunlight is estimated to cause a 5% loss of vitamin C in fruits each day. In the case of vegetables, this figure can be as high as 10%.
On the other hand, photodegradation produces changes in the color, texture, taste and smell of food, as well as in its nutritional value. In the case of oils, photooxidation leads to an increase in peroxide molecules, which adversely affects their quality.
Therefore, the objective of environmental chambers for the photostability of food allows assessing changes in the chemical composition, texture, color, taste and odor of food and the development of new photomethodes for the control of photostability.
Environmental Chamber Types
There are different types of environmental cameras for food photostability, and we will introduce you to some of the most common and their characteristics.
Solar cameras
Solar chambers are devices that allow accelerating the process of natural aging of food, using solar radiation as an acceleration factor. They are usually equipped with a light controller, which allows to regulate the intensity of the solar radiation to which the product is subjected. In this way, the speed of the aging process can be adjusted, thus simulating different environmental conditions.
Ultraviolet cameras
Ultraviolet cameras are devices that use ultraviolet radiation to accelerate the natural aging process of food. Ultraviolet cameras are usually equipped with a light controller, which allows regulating the intensity of ultraviolet radiation to which the product is subjected. In this way, the speed of the aging process can be adjusted, thus simulating different environmental conditions.
Fluorescent cameras
Fluorescent cameras are devices that use fluorescent light to accelerate the natural aging process of foods. They are usually equipped with a light controller, which allows to regulate the intensity of the fluorescent light to which the product is subjected. In this way, the speed of the aging process can be adjusted, thus simulating different environmental conditions.
