(54) METHOD OF PREPARATION OF ROOT FRODS

The invention relates to a technology for treating root crops before storage and can be used in agriculture, in fruit and vegetable bases and in trade.

There is a known method of protecting root crops, for example, beets from spoilage when stored in kagats, including treating root crops when laying, with a storage of 0.85-1.30% solution of propionic acid, in which 1.5-2.0% sodium or ammonium salts of alkyl sulfates, and the solution is foamed to a multiplicity of 70100.

The method is especially effective in the years of mass deterioration of beets when stored in caghats as a result of the development of microflora of coagulant rot.

After 30 days of storage, the beet roots processed in this way have rot 4,1 times less, and the sugar content increases by 2.3% 11.

However, the substances used in the method are foreign to the plant organism, have insufficient bactericidal properties and do not disinfect the environment (environment. STORAGE

Closest to the present invention is a method of preparing root crops for storage, which involves treatment with an aqueous solution of iodkrachmal and subsequent blowing with cold air.

This treatment ensures the formation of a thin protective film of iodopolymer on the surface of the fruit.

ten

The known method allows fruit and vegetables to be stored for a long time, since iodarch is an antiseptic and creates a bactericidal environment around the fruit, thus preventing them from various diseases.

However, since the vegetables come in for processing unwashed, dirty, and therefore on root vegetables under the film

20 iodopolymers remain foci of land, which impede the access of iodkrachmal to the fetus and thereby contribute to the development of mold and rot, which increases the amount of waste during storage.

The purpose of the invention is to reduce the amount of waste during storage.

The goal is achieved

30 by the fact that in the root method the 2 fruits are pre-washed in running water for 1-2 minutes, 0.20, 5% aqueous solution of starch is added sodium bicarbonate in the amount of 2.5-4.0%, while processing lead for 20-40 s.

The proposed method of processing, before storage, provides for the formation of iodopolymer directly on the surface of the washed protective film, which effectively protects them from microorganism damage.

Example 1 A carrot is washed with clean running water for not more than one minute and immediately sent for treatment with a 0.2% aqueous solution of iodkrachmal with the addition of sodium bicarbonate in an amount of 2.5%. The treatment is carried out for 20 s and, after being blown over by currents of cold air for 30 s in order to remove droplet moisture from the surface, the carrots are packed in containers and sent to

storage at ambient temperature + 1 ° С + 0.5 С, relative humidity of ambient air 95% ± 2%.

Example 2. Sugar beets are washed with cold water for not more than two, and then immediately treated for 40 s using a sprinkler with a 0.5% aqueous solution of iodkrachmal with the addition of sodium bicarbonate in an amount of 4.0%. After that, the roots are blown with a stream of cold air, loaded into containers and sent to storage at an ambient temperature of + 0, and a relative humidity of ambient air of 95% + 2%.

The results of storing carrots after prolonged storage are presented in Table 1. For comparison, information is given on the storage of carrots, which have not undergone any processing before storage, and carrots that have been processed before storage according to a known method. Table 1

From the table it follows that the processing of carrots before storage by the proposed method provides the highest yield of standard products, while absolute rot is absent.

Laboratory tests showed that the carrots that had passed before the 45-hour storage were processed by the proposed method, it is well characterized by the table, that the sugar beet, previously processed by the proposed method, can be stored for a longer time than the beetroot. With this exit

and

taste and aroma, dense structure of fabric.

The results of the storage of sugar beet, previously processed by the proposed method are presented in Table 2. For comparison, the results of storing beets without prior treatment are given.

table 2

healthy root vegetables are increased by 11%, and the amount of waste is also reduced by 11%. A significant advantage is that the content of reducing sugars is noticeably reduced and the sucrose content increases, 4to will increase the sugar yield from beets.

Thus, the proposed method provides effective processing of the roots before storage and allows them to be stored for a long time until the new harvest. Thus, the yield of root crops after prolonged storage is about 99%,

In addition, the proposed method can be used for treating root crops removed from the shoulders during the spring period and transferred to the refrigeration chambers ЕЕ% 1 as the plant organism is weakened during this period and is easily susceptible to disease.

One of the important advantages of the proposed method is that, after storage, the roots have a good & marketable appearance: they are clean, free from areas of dirt and rot on the surface, and retain good chemical composition components.

After storage, the roots can be sent directly from storage facilities for sale.

The proposed method of treating root crops before storage promotes the healing of cuts on their surface and prevents the development of microorganisms in these places.

The proposed method can be used for; pre-treatment of root vegetables such as carrots, beets, turnips, celery, etc.

The economic effect obtained by processing this method of 1 ton of carrots at the fruit and vegetable base of the Krasnogvardeysky pishchetorg, Dnepropetrovsk, is about 43 rubles

With the widespread introduction of the proposed method, the effective effect can be a significant amount.

 the invention

The method of preparing root crops for storage, envisages the treatment of an aqueous solution of iodo starch and subsequent blowing with cold air, characterized in that, in order to reduce the amount of waste during storage, the roots are pre-washed in running water for 1-2 minutes, in 0.2- A 0.5% aqueous solution of iodkrachmal is injected with sodium bicarbonate in an amount of 2.5-4.0%, and the treatment is carried out for 20-40 s.
