In the last years, in addition to continued studies of the impact of CA/MA atmospheres on product physiology and quality and the search for optimal atmosphere composition for specific commodities, new research areas have been explored: CA/MA effectiveness in combination with co-treatments, extreme concentrations of O2 and/or CO2, innovative gases to substitute nitrogen, impact of CA/MA on nutritional and sensorial attributes. All these aspects, together with recent developments in packaging technologies and with economic aspects related to both sustainability and environmental implications, will play an important role in the XI International Controlled & Modified Atmosphere Research Conference, which will be held in Trani, Italy on June 3-7, 2013. Italy has always been a leading Country for the horticulture production, with major reference to pome and stone fruit, table grapes, kiwifruit and several vegetable crops. About 60% of the estimated 14 millions m3 storage volume is equipped with CA technology applied in particular for long-term storage of apples (84% of the total) , pears (44%), and kiwifruits (35%). On the other hand, vegetable industry is also well developed (leafy greens, artichokes, potatoes and tomatoes), and Italy represents one of the largest European markets for fresh-cut salads, where MAP is commonly applied. Apulia Region contributes one fifth of national horticultural production. Seventy per cent of table grapes and sweet cherries, and more than 30% of tomatoes, cauliflowers and artichokes are produced here. The Region is also known for the artistic/historical landmarks and for its beautiful coastline along the Adriatic and Ionian sea, punctuated with gorgeous beaches and marine views. June is a most favorable season, with the bless of summer weather, without the crowd of the high season. Trani is a jewel medieval city on the Adriatic sea, half-an-hour north of the International airport of Bari, the south-eastern tip of the Italian peninsula: the very “heel of the boot”. The venue of |CA|MA|2013| will be located in the lively heart of the old city, within walking distance from hotels and lodgings, with a beautiful view on the harbor and onto the unique romanesque Cathedral. The conference will provide an invaluable opportunity for scientists, professionals, and students to present their latest findings in research, to share ideas, and to discuss common issues. The meeting will promote International cooperation and networking in CA/MA research and technology applications, with the particular aim to involve emerging Countries.
