In Bosnia conagra foods grand rapids mi and Herzegovina so far for longer storage of fruits and vegetables exclusively used conventional cooling conagra foods grand rapids mi technologies. Rare are the objects that have been able to provide a controlled atmosphere in the chamber, although this technology has long been used in svijetu.Posljednjih years more and more objects are installed in refrigerated equipment that can provide a controlled atmosphere. As this technology there are no great experience in our country, in this document will attempt to shed light on this technology on all sides, so that it could more easily be used.
This manual has been developed as a result of the project titled HLADNJAČE with low oxidation levels (ULTRA LOW Oxigen / ULO), which is supported by the Federal Ministry of Agriculture, Water, food industry and forestry BiH. The aim of writing this handbook is to provide practical information to potential investors and other stakeholders about the modern way of storing fruits and vegetables in fresh condition. It is worth to point out that fresh fruit and vegetables, in addition to quality food, has an important role in the protection of human health.
In the Federation of Bosnia and Herzegovina during the year table fruit, especially apples and pears, conagra foods grand rapids mi are intended for consumption in the fresh state are imported. In recent years, increased lifting fruit plantations, so it would be unrealistic to expect an increase conagra foods grand rapids mi in fruit production and consumption in fresh condition. Due to the lack of modern capacity for keeping fruit fresh, if this trend continued, the producers would have been forced conagra foods grand rapids mi to adapt it in less nutritionally valuable foods. Therefore, conagra foods grand rapids mi it is necessary to plan for the timely training of producers and investors to prepare for more advanced forms of production and preservation of fruits and vegetables. Using modern technology postharvest preservation of fruits and vegetables in fresh condition of the technical basis for: faster development of fruit production, substitution of imports of fresh fruit and vegetables conagra foods grand rapids mi and creating conditions for the export of fresh fruits and vegetables.
ULO cold, in fact, used for cold-storage preservation of fresh fruits (mostly apples and pears) in a controlled atmosphere (CA). Under controlled atmosphere conagra foods grand rapids mi means the atmosphere in which the controlled atmosphere storage control reference conagra foods grand rapids mi parameters (CO2, O2, temperature, relative humidity), which are characteristic for each species and varieties conagra foods grand rapids mi of vegetables and fruits.
Controlled atmosphere affects the biochemical reactions. It is essential the effective concentration of the ingredients of the atmosphere in the storage area as well as in the plant cell tissue. The controlled atmosphere inhibiting the biochemical reactions that lead to the formation of ethylene-stimulator ripening. Thus extending the storage time and maturation, because it reduces the intensity tet respiration due to the absence of ethylene. In this sense, the klimakterijskog fruit is no menopause, if oxygen around 2-3%, and internal oxygen concentration 1-2%. On the basis of these findings, in the controlled atmosphere promoted so. ULO system (an abbreviation of the English Ultra Low Oxygen - low oxygen content), which is reduced to maintain ing on very small fluctuations of oxygen. Simultaneous decrease in temperature and a decrease in the oxygen content or increasing the share of CO2 can slow down the process of breathing, or slow down the biochemical changes. This slows down the process of maturation, while preventing softening of the fruit, making foreign conagra foods grand rapids mi smell, taste and color.
Manual consists of an introduction and four chapters. After the introduction, the second section describes the importance of fruits and vegetables in the diet. They started from the fact that Bosnia and Herzegovina has extraordinary natural conditions for growing conagra foods grand rapids mi fruits and vegetables, and planned to raise the capacity to retain the fresh can create an opportunity for the development of horticulture on the one hand, and on the other better nutrition of the population. Therefore, this chapter describes the most important kinds of fruits and vegetables that are grown in BiH, their consumption, imports and exports for the past few years.
The third chapter describes the processes that lead to changes in fruits and vegetables after harvest, especially the processes of respiration (breathing), transpiration (water loss), ripening, maturation and possible microbiological conagra foods grand rapids mi changes. Knowing the nature of these changes is essential in preventing the possible consequences of the loss of quality of freshly conagra foods grand rapids mi picked fruits and vegetables.
The fourth chapter describes the processes of storing fruits and vegetables in fresh condition ranging from classical cooling, controlled ventilation, conventional controlled atmosphere, ULO conditions, micro-and conagra foods grand rapids mi dynamic atmosphere, etc. Especially with procedures removal of oxygen in
