METHOD OF PROCESSING PLANT RAW MATERIALS TO PRODUCE PECTIN AND FOOD PRODUCTS CONTAINING PECTIN AND LINE FOR THIS IMPLEMENTATION Russian patent published in 2009 - IPC A23L1/524 

FIELD: food products.

SUBSTANCE: method includes preparing of plant raw material by mixing it with water citric acid solution of pH 2.3-3.6 with relation of raw material and water solution 1:(1-3). And also with amylolytic enzymes and pectin in proportion of 0.01-0.05 wt % and 1.5-2.1 wt %. Prepared plant raw material is sequentially gone through treatment on rotary chopper disperser, rotary-cavitational extractor and ultrasonic reactor till disperse mass is produced with temperature of no more than 65°C and particles size less than 1 mcm. Produced disperse mass is centrifuged with separation coefficient Fr=6000-100000 to pectin containing fibre and liquid pectin containing disperse phase. It is sent to press filter with pressure of 0.3 MPa, it is microfiltered till low-molecular suspensions are no more than 1.0%. Then it is sequentially gone through ultrafiltration, diafiltration and nanofiltration till low-molecular suspensions in pectin containing concentrate are no more than 0.18%, then the concentrate is dried on low temperatures. The second invention is a line of plan raw material processing to produce pectin and food products containing pectin. The technological process contains preparation of pectin containing raw material, which includes preparation of fresh raw material and dry raw material. All of them are connected with units including at least two containers for hydromodulus production. Then there are solution preparation block, block of hydrolytic extraction of pectin containing raw material, block of separation and concentration of produced disperse mass and unit for drying pectin, in a form of low temperature drying unit. Block of hydrolytic extraction of pectin containing raw material is presented as a system with at least three rotary chopper dispersers, three rotary-cavitational extractor and ultrasonic reactor with adjustable generators. Mentioned above reactors are set up in every transitional storage container for disperse mass. Block of separation and concentration of disperse mass includes sequentially set up centrifuge, press filter, microfilter, ultrafilter, diafilter and nanofilter units.

EFFECT: process of pectin containing raw material production is intensified, processing technologies are disposable, quality and purification rate of products starting with low-molecular connection are increased, native qualities of raw material are remained.
