Combined drying products
Most foods contain a significant amount of water that enters the plant and
animal tissue and is an essential component part of them. However, an excess of
water reduces the nutritional value of food, increases transportation costs and
can cause damage as a result of vital activity of various microorganisms.
Every year in Belarus is going to considerable crop of vegetables, fruits and
berries. But to table comes from the grown no more than 30%. Issues of storage
and processing, reduce losses, save the presentation, and will be relevant to each
producer and processor of agricultural products.
In this regard, Kazakhstan is necessary to draw attention to the dried
vegetables, fruits as a market segment that is underdeveloped. Discover sale this
domestic production is extremely difficult. Almost the same things, our
neighbors near and far abroad (Russia, Ukraine, Poland, the Baltic States), and
(Germany, Czech Republic, etc.). Of the total agricultural production are
currently dried only 6 - 8%, whereas in the United States in this way up to 30%
harvested crop grown.
Before the food industry in recent years sharply raises the question of
creating a product or group of products, which could become the brand of
Belarus, the Republic of Kazakhstan on the world food market. On it you can
come up with new products like fruit - berry (. Of apples, plums, pears,
strawberries, etc.) and vegetables (. Of carrots, beets, pumpkin, Jerusalem
artichoke, etc.) "candy" humidity 12 - 25%, candied fruit - 28 - 37%, dried meat
(beef, pork, chicken) fillets, fish delicatessen products, cheese "crispy", albumin
cheese, herbal teas, royal jelly, and others.
Fundamentals of ozone - air drying
Exposure to ozone in the first stage drying plant materials initiates stomatal
movement, which regulates the rate of transpiration. Its gain induced by ozone,
resulting in a sharp decrease in hydration of plant tissue, loss of turgor pressure
and causes a violation of regulatory functions of stomata.
Since moisture in the foods is not simply a physical condition, and in the
related, i.e. involved in the processes of life, it has a different form of
communication, requiring large amounts of energy for their destruction.
Ozone is directed onto the surface of the plant material, promotes free
radical processes, fast propagating in internal tissues, and is reduced
substantially to transfer energy released on the molecular target of the surface
layer of plant material in the internal tissues and thus to a change of the total
energy potential . In this part of the excess energy spent on physical - chemical
transformations, associated with changes in the structure of cell membranes, ion
permeability, oxidation - reduction potential and other properties of the cells.
