Abstract
Description
Vynález sa týká sposobu úpravy kukuřičného Škrobu.The invention relates to a method for treating corn starch.
Nedostatkom doteraz vyráběného kukuřičného škrobu je jeho nažltlá farba, prirodzený pach, prítomnosť neškrobových komponeatov, předurčených fyzikálnymi a chemickými podmienkami výroby a sprievodné látky, přípustné československou štátnou normou OH 56 6102 z 31. 3. 1965.The shortcomings of the maize starch produced hitherto are its yellowish color, natural odor, the presence of non-starch components, predetermined by the physical and chemical conditions of production, and the accompanying substances permitted by the Czechoslovak state standard OH 56 6102 of 31 March 1965.
Uvedený nedostatek odstraňuje sp3sob úpravy kukuřičného Škrobu podía vynálezu, ktorého podstata spočívá v tom, že 35 až 45 % škrobová suspenzia sa po predchádzajúcej homogenizácii podrobí extrakci! 75 až 96 % etylalkoholom aspoň jedenkrát pri teplote varu etylalkoholu do 90 minút, získaný kaveraovaný škrob sa po odstránení extrakčného činidla íalej maceruje 75 až 96 % alkoholom pri teplote 20 až 45 °C po dobu 60 minút.This drawback removes the process for treating corn starch according to the invention, which consists in subjecting the 35 to 45% starch suspension to be extracted after prior homogenization. 75 to 96% ethyl alcohol at least once at the boiling point of ethanol for 90 minutes, the obtained starch is further macerated with 75 to 96% alcohol at 20 to 45 ° C for 60 minutes after removal of the extractant.
Kukuřičný škrob upravený podl'a vynálezu je kavernovaný, vybielený, odtučnený, dezodorovaný a purifikovsný. Kavemát tvoria oválné alebo polyedrioké 2 až 35 mikrometricky veíká škrobové zralečka s dutinami alebo 2 až 5 ramennými puklinami, javiace v polarizovanom svetle čierny kříž. Kavernovaný kukuřičný škrob, amyllum cavernatum purissimum, podía vynálezu nie je rozpustný v studenej vodě a 96 % aletylalkohole, v 5 % vodnej suspenzii utvára hodnotu pH 4,5 až 6,0, neobsahuje viac ako 0,09 % síranového popola v sušině, 0,065 až 0,080 % celkového dusíka v sušině, množstvo retrogradaonej vody po 3 dňoch státia nepřesahuje 10 cm^ a dosahuje 95 % bělost*.The corn starch treated according to the invention is cavernated, bleached, defatted, deodorized and purified. The cavemate is an oval or polyhedral 2 to 35 micrometer sized starch with cavities or 2 to 5 shoulder cracks, appearing in a polarized light with a black cross. Cavernated corn starch, amyllum cavernatum purissimum, according to the invention, is not soluble in cold water and 96% of ethyl alcohol, in a 5% aqueous suspension it forms a pH of 4.5 to 6.0, contains no more than 0.09% of sulphated ash in the dry matter, 0.065 up to 0.080% of the total nitrogen in the dry matter, the amount of retrograde water after 3 days of standing does not exceed 10 cm @ 3 and reaches 95% whiteness *.
Upravený kukuřičný škrob podía vynálezu možno použit* ako nosič pri výrobě liečív vzhíadom na to, že vyhovuje požiadavkám ČSL - 4, ňalej ako nosič potravinářských farbív a vonných a chuťových látok.The treated corn starch of the present invention can be used as a carrier in the manufacture of medicaments, since it complies with the requirements of CSL-4, hereinafter as a carrier for food colorings and flavorings.
Příklad 1Example 1
Na kavernovanie a fyzikálno-chemickú purifikáciu sa z 10 kg kukuřičného škrobu vytvoří 35 % suspenzia s 96 % etylalkoholom, ktorá po homogenizácii a dehydratácii zrniečok škrobu sa zahřeje do varu a extrahuje 5 minút. Po odstranění extrakčného činidla sa kavernovaný-škrob maceruje s 80 % etylalkoholom 120 minút, pri teplote 30 °C. Vyťažilo sa 92,5 % kavernátu, ktorý sa pri tepíote 85 °C. vysušil na 93,5 % sušinu. Odfiltrovaný 85 % etylalkohol sa zregeneruje destiláciou.For caverning and physicochemical purification, a 35% suspension of 96% ethyl alcohol is formed from 10 kg of corn starch, which, after homogenization and dehydration of the starch beads, is heated to boiling and extracted for 5 minutes. After removal of the extractant, the cavern-starch is macerated with 80% ethyl alcohol for 120 minutes at 30 ° C. 92.5% of the cavernate was recovered, which was at a temperature of 85 ° C. dried to 93.5% dry matter. The filtered 85% ethanol is recovered by distillation.

Po odstránení extrakčného činidla sa kavernovaný škrob maceruje s 80 % etylalkoholom 120 minút pri teplote 30 °C. Vyťažilo sa 92,4 % kavernátu, ktorý sa pri teplote 85 °C vysušil na 93,5 % sušinu.From 10 kg of corn starch, a 35% suspension with 96% ethyl alcohol is formed which, after homogenization and dehydration of the starch grains, is heated to boiling and extracted for 5 minutes. After removal of the extractant, the cavernated starch is macerated with 80% ethyl alcohol for 120 minutes at 30 ° C. 92.4% of the cavernate was recovered and dried to 85.5% solids at 85 ° C.
