Light and mechanical injury are the two most important environmental factors which stimulate postharvest glycoalkaloid synthesis in potato tubers. Partial control of light-induced glycoalkaloid formation has been achieved by treating potato tubers with some chemicals as Ethephon, Alar, Phosphon, Phosphon-S, Amchem 72-A42, Amchem 70–334, Nemagon, Telone, detergents, surfactants, control-atmosphere storage and subatmospheric pressure storage. Complete inhibition of light-induced glycoalkaloid formation can only be obtained by hot wax coating, oil coating, vacuum packaging and anoxia water submersion. Treatment with isopropyl-N-(3-chlorophenyl)-carbamate and gamma-irradiation effectively control wound-induced glycoalkaloid formation of potato tubers.

Temperature Storage

Tubers from 7 potato varieties were analyzed for their rates of glycoalkaloid accumulation in response to stresses of three types of mechanical injury and low temperature storage. Mechanical injuries were found to greatly stimulate glycoalkaloid accumulation in both peel and flesh of tubers. The extent of glycoalkaloid accumulation appears to depend on variety, type of mechanical injury, and storage period. Most of the injury-stimulated glycoalkaloid accumulation occurred within 7 and 14 days after treatment. Cutting the tubers resulted in the highest content of glycoalkaloids both in flesh and peel up to levels that exceeded the upper safety limit of 200 mg/kg FW. Injury stimulated α-solanine accumulation in stored potato tubers is more than α-chaconine, resulting in a decrease in the α-chaconine: α-solanine ratio. When tubers were stored at low temperature, the rate of glycoalkaloid accumulation was found to be independent of the glycoalkaloid level at harvest. The greatest increase in total glycoalkaloid content of the seven varieties was found after two weeks of storage at both 4 ºC and 10 ºC. Further storage at these temperatures resulted in a decrease in the rate of glycoalkaloid accumulation in most of them. At 10 ºC glycoalkaloid content tended to increase more rapidly than at 4 ºC. The α-solanine content of the tubers showed an increase following low temperature storage.

The development and production of vegetables are increasing in every corner of the globe. Besides fresh and quality vegetables, which are the central pillar of generating economies and business, there is also demand and requirement to differentiate and create post harvest storage, transport, publicity, and preparing the foundation to broaden the utilization of vegetables beyond rising seasons and localities. However, numerous Western nations have created vegetables appropriate for cold environments, including potatoes and tomatoes, to tackle the issue. The countries of tropical areas, like China, India, Brazil, Pan American nations, and nations of Africa, South-East Asia, and Central Asia, have an appropriate environment and assets to cultivate numerous kinds of vegetables. However, the present paper examines the significance of control the atmosphere storage of vegetables and how it affects various foodstuff quality and marketing. The study is based on secondary data. The study systematically reviews many articles, reports and books. The results reveal that the control atmosphere storage enhances the quality of the product that increases the product's suppy and demand. Furthermore, it shows that controlled atmosphere storage is the one most appropriate innovation that can guarantee long storage of vegetables that enhances the freshness and best marketing of the products. The vegetables are kept up through the utilization of explicit CA storage conditions to every product and control of the gas elements, temperature, and relative humidity of the climate. Notwithstanding these components, digestion changes of vegetables have been considered to set up the ideal storage conditions. This is enlarging the improvement of a quick storage system.
