Description

Vynález rieši sposob zvýšenia obsahu bielkovín v škrobárenskom odpade z výroby kukuřičného škrobu za účelom zhodnotenia tohoto odpadu ako krmivá so zvýšeným obsahom bielkovín.The present invention provides a method for increasing the protein content of starch waste from the production of corn starch for the purpose of recovering this waste as a feed with increased protein content.

Pri výrobě škrobu z kukuřice vzniká určité množstvo odpadu, obsahujúceho neškrobové zložky rastlinnej suroviny, hlavně bielkoviny a látky celulózového charakteru, tzv. hrubú a jemnú Vlákninu. Tieto látky (hlavně podiel jemnej vlákniny) obsahujú a zároveň so sebou strhávajú časť škrobu, ktorý je pri súčasnej úrovni technológie neseparovateíný. V súčasnosti sa jemná vláknina využívá ako tekuté krmivo v živoČíšnej výrobě. V zahraničí sa tento podiel suší separátně alebo spolu s ostatnými neškrobovými zložkami a využívá sa tiež ako krmivo. Stráca sa tým cenný škrob, ktorý je možné lepšie zúžitkovať v biotechnologických výrobách, krmivo právě zastúpením škrobovej zložky má nižší obsah bielkovín, nie je možné ho preto používat do krmivových zmesi ako aditívum s vysokým obsahom bielkovín. Využíváme jemnej vlákniny ako tekutého krmivá vyžaduje náročnú dopravu autocisternami, pričom jeho použitie je časovo obmedzené vzhladom na krátku trvantlivosť.In the production of starch from maize, a certain amount of waste is produced, containing non-starch components of the vegetable raw material, mainly proteins and cellulosic substances, the so-called coarse and fine fibers. These substances (mainly the proportion of fine fiber) contain and at the same time entrain with them part of the starch, which is currently irreplaceable. Currently, fine fiber is used as a liquid feed in animal production. Abroad, this portion is dried separately or together with other non-starch ingredients and is also used as feed. This loses valuable starch, which can be better used in biotechnology production, the feed being represented by the starch component has a lower protein content and therefore cannot be used in feed mixtures as a high protein additive. We use fine fiber as a liquid feed requiring heavy transport by tank trucks, its use limited in time due to short durability.

Uvedené nedostatky odstraňuje navrhovaný spdsob zvýšenia obsahu bielkovín, ktorý spočívá v enzymatickom stekutení škrobovej zložky jemnej vlákniny a následnej separácii od tuhého podielu. Stekutenie škrobovej zložky sa vykonává pri teplotách 30 až 90 °C po dobu 0,2 až 1,5 h enzymatickým súborom s a-amylolytickou aktivitou. Množstvo přídavku enzýmu je závislé na jeho aktivitě a je na každý kg odpadu jemnej vlákniny také, aby zodpovedalo najmenej 560 jednotkám dextrinačnej aktivity DA. Podmienky stekutenia sa s výhodou voliaThese drawbacks are eliminated by the proposed method of increasing the protein content, which consists in enzymatically liquefying the starch component of the fine fiber and then separating it from the solids. The liquidation of the starch component is carried out at temperatures of 30 to 90 ° C for 0.2 to 1.5 hours by an enzymatic assembly having an amylolytic activity. The amount of enzyme addition is dependent on its activity and is also for each kg of fine fiber waste to correspond to at least 560 DA dextrination activity units. The fluidisation conditions are preferably selected

PREDMETOBJECT 1. Spósob zvýšenia obsahu bielkovín v škrobárenskom odpade, vznikajúcom pri spracovaní kukuřice na škrob, vyznačujúci sa tým, že na odpad z výroby kukuřičného škrobu s obsahom sušiny 0,03 kg/kg až 0,18 kilogramov/kg sa pósobí enzýmovým súborom s α-amylolytlckou aktivitou pri teplote 30 až 90 °C po dobu 0,2 až 1,5 111. A method of increasing the protein content of starch waste resulting from the processing of maize into starch, characterized in that the waste from the production of starch from maize with a dry matter content of 0,03 kg / kg to 0,18 kilograms / kg is treated with an enzyme set with α -amylolytic activity at 30 to 90 ° C for 0.2 to 1.5 11 2. Spósob podfa bodu 1, vyznačujúci sa podfa optima pre daný súbor enzýmov. Separácia stekutenej zložky od tuhej fázy sa vykoná s výhodou na kontinuálně pracujúcich odstředivkách. Odstránením škrobovej zlcžky sa v jemnej vláknině zvýši obsah bielkovín a je možné takto opracovanú frakciu použit buď priamo, alebo po vysušení ako krmivo s vysokým obsahom bielkovín, připadne ju použiť ako prídavok do krmivových zmesi za účelom zvýšenia obsahu bielkovín. Navýše sa získá škrobový hydrolyzát z tej časti škrobu, ktorá sa pomocou doposial' známých technologických postupov nedá oddělit od neškrobovej zložky. Hydrolyzát je možné spracovať v llehovare, připadne použiť ako sacharidový podiel žlvnej půdy v biotechnologické) výrobě. V duplikátorovej nádrži sa 1 000 kg kukuričnej jemnej vlákniny s obsahom sušiny 0,1 kg/kg a zloženia sušiny 0,5 kg/kg škrobu; 0,2 kg/kg bielkovín; 0,3 kg/kg celulózových látok podrobilo stekuteniu prídavkom 225 g enzýmového preparátu s «-amylolytickou aktivitou, ktorá má aktivitu 2 500 jDA/g. Teplota pri stekutení bola 65 aC, čas stekutenia 0,5 h. Materiál po stekutení sa viedol na odstředivku, kde sa separovala od seba kvapalná a tuhá fáza. Kvapalná fáza, obsahujúca sacharidové látky sa zahustila na odparovacej batérii na obsah sušiny 0,65 kg/kg. Tuhá fáza sa vysušila na obsah sušiny 0,85 kg/kg a získaný suchý produkt sa pomlel a egalizoval.

A method according to claim 1, characterized in that it is optimized for a given set of enzymes. Separation of the flowable component from the solid phase is preferably carried out on continuously operating centrifuges. Removing the starch pulp increases the protein content of the fine fiber and can be used either directly or after drying as a high protein feed, or as a feed additive to increase the protein content.

The flow temperature was 65 [deg.] C., the flow time was 0.5 h. The material after flow was led to a centrifuge where the liquid and solid phases were separated. The carbohydrate-containing liquid phase was concentrated on an evaporating battery to a solids content of 0.65 kg / kg. The solid phase was dried to a dry matter content of 0.85 kg / kg and the obtained dry product was milled and leveled. The thickened liquid phase is used as a nutrient stage or part thereof in biotechnological production, e.g. in the production of citric acid, enzymes, antibiotics. The dried solid phase is used as feed or as a feed additive in animal feed.
