Description

The invention relates to a technology for the production of an inulin-containing solution for food or medical purposes.

There is a method of producing an inulin-containing solution from Jerusalem artichoke, which includes washing Jerusalem artichoke, inspecting it, processing in a microwave field to inactivate native enzymes, pressing to separate juice from squeezes, extracting extracts with drinking water, blending juice and extract, adding citric acid, heating, clarification with bentonite, centrifugation and filtration to obtain the target product (J. Ibramji, Use of Jerusalem artichoke in the technology of canned fruit. Abstract of thesis, Candidate of Technical Sciences - Odessa: OTIPP, 1993, pp. 7-13) .

The disadvantage of this method is the low yield of inulin, amounting to not more than 63% of theoretically possible, and the unsuitability of the target product for storage due to hydrolysis of inulin with citric acid.

Closest to the proposed is a method of producing an inulin-containing solution from Jerusalem artichoke, which includes washing Jerusalem artichoke, steam cleaning, tertiary treatment, cutting, blanching, rubbing, extracting with acidified water and separating the liquid phase as the target product (Akopyan Yu.R., Development of technology for producing fructose syrup from Jerusalem artichoke.Abstract of dissertation of a candidate of technical sciences - M .: MGAPP, 1994, pp. 6-14).

This method allows to increase the yield of inulin to 83.2% of theoretically possible, but has a high energy intensity and high color of the target product.

The technical result of the invention is to reduce energy intensity and color reduction of the target product.

This result is achieved by the fact that in the method for producing an inulin-containing solution, which involves washing and grinding the inulin-containing raw materials, extracting them with acidified water and separating the liquid phase as the target product according to the invention, scorzone is used as the inulin-containing raw materials, extraction is carried out at a phase ratio of 1: 1 , 2, pH 5-6.5, temperature 55-65 ° С and periodic depressurization of the extraction mixture until the extractant boils, the extraction mixture is pretreated ke in the microwave field until the inactivation of native enzymes, and the separated extract is concentrated by reverse osmosis to a solids content of 15-20%, subjected to photo sterilization and packaged under aseptic conditions.

The method is implemented as follows.

Scorzoner is washed, inspected and ground, for example, on a crusher to a particle size of 1-2 mm. The ground mass is poured with acidified water until the extraction mixture reaches a pH of 5-6.5 with a phase ratio of 1: 1.2, it is processed in the microwave field until the native enzymes are inactivated at the recommended process parameters (Gubiev Yu.K., Scientific and practical fundamentals of food thermotechnological processes production in a microwave electromagnetic field. Abstract of a thesis of Doctor of Technical Sciences - M .: MTIPP, 1990, p. 32-33), extracted at a temperature of 55-65 ° C and periodically depressurizing the extraction mixture until the extractant boils at the recommended process parameters (RU 2255788 C1, 2005) and phase separation by any known technology. The liquid phase is concentrated by reverse osmosis to a solids content of 15-20%, subjected to photo sterilization and Packed under aseptic conditions to obtain the target product.

It has been experimentally established that when implementing the described technology, the inulin yield is 87% of the theoretically possible. The color of the target product A ₄₇₀ , obtained by the described technology and the closest analogue, amounted to 0.018 and 0.350, respectively. The energy consumption of the proposed method compared with the closest analogue is reduced by approximately 15%. At the same time, the target product has a shelf life of at least 1 year without significant changes in consumer and technological properties.
