Chairat Techavuthiporn is a Professor in Postharvest Technology in the School of Industrial Education and Technology, King Mongkut’s Institute of Technology, Ladkrabang, Thailand. His field of specialization is postharvest biology and technology of tropical fruit and vegetables. He studied at The University of the Thai Chamber of Commerce and King Mongkut’s University Thonburi, both in Thailand, and Gifu University, Japan, where he was awarded a PhD degree. He has more than 15 years teaching experience in courses on postharvest technology of agricultural products and introduction of food science and technology to undergraduate students and advanced postharvest technology to MSc and Ph.D. students. He has also published more than 20 papers in international journals.
Controlled and/or modified atmosphere conditions have been used for preserving quality of fruit and vegetables after harvest. This technique may prevent or lessen postharvest changes such as texture, flavor, color and chemical composition. This procedure entails eliminating O2 and raising CO2 content. Because fruit and vegetables are living organisms, they require proper O2 and CO2 concentrations for their respiratory activity. Plant cells perform anaerobic respiration when O2 levels are low or CO2 levels are high, producing lactic acid, acetaldehyde, and ethanol. The degree of anaerobic activity depends on how long cells are exposed to air. Prior to storage, therefore, treating fresh commodities with an anaerobic environment or anoxic conditions inhibited physiological changes and disorder and improved nutritional qualities of pineapple fruit, asparagus, broccoli, and fresh-cut pineapple. Our study's findings suggest that anoxia treatment, a non-chemical and simple postharvest method, would appropriate for usage where food storage technologies are limited.
