Description

Vynález rieši spósob úpravy pivovarských kvasničných kalov pre použitie na fortifikáciu potravin.The present invention provides a method for treating brewing yeast sludge for use in fortifying foods.

Pivovarské kvasnice obsahujú v sušině do 40 hmot. bielkovín a vitamíny skupiny B. Ich nedostatkom je vysoký obsah nukleovýjCh kyselin (okolo 7 % v sušině) a horkých látok z chmelu adsorbovaných na ich povrchu.Brewer's yeast contains up to 40 wt. Protein and group B vitamins. Their deficiency is high content of nucleic acids (about 7% in dry matter) and bitter hops adsorbed on their surface.

Doteraz sú známe sposoby využitia pivovarských kvasnic, ktoré boli predtým odhorčeiné prepieraním studenou vodou po značné dihú dobu. Tento spósob vyžaduje velké množstvo studeoej, čistej, zdravotně nezávadnej vody, pričom sa nie vždy dosahuje rovnaký účinok. Tonto spósob nezabezpečuje znižovanie oíbsahu nukleových kyselin v 'kvasniciach. Výrobky, vyrobené za použitia váčšieho množstva kvasnic, dostávajú jemne nahorklú chuť a po zdravotnej stránke je nebezpečie, že sa překročí dovolený příjem nukleových kyselin organizmom. Vysokoúčinný, známy výrobok „PANGAMÍN“ má nepríjemne horkú chuť a tmavú farbu, preto ho najmá děti odmietajú. Podobné výrobok ,,Β-komplex“ pre medicinálně účely je chuťovo ovplyvnený autolyzovanými kvasnicami a do určitého stupňa horkými látkami.So far, there are known ways of using brewer's yeast, which had previously been burnt out by washing with cold water for a considerable period of time. This method requires a large amount of cold water, clean, wholesome water, and the same effect is not always achieved. This method does not ensure a reduction in the content of nucleic acids in yeast. Products made using a large amount of yeast are given a slightly bitter taste and, from a health standpoint, there is a risk that the organism's permissible intake of nucleic acids will be exceeded. The highly effective, well-known product "PANGAMINE" has an unpleasantly bitter taste and dark color, which is why it is denied by children in particular. A similar product "komplex-complex" for medicinal purposes is flavored by autolysed yeast and to some degree by bitter substances.

Spomenuté nedostatky odstraňuje navrhovaný spósob úpravy pivovarských kvasničných kaloív podta vynálezu tým, že na upravené kvansnice působíme horúcim etanolom, ktorý rozpúšťa horké látky, znižuje obsah nukleových kyselin a desolvatuje bielkoviny, čím vlastně zabraňuje autolýze, dósledkom čoho nevzniká nepříjemná příchuť.The aforementioned drawbacks are overcome by the proposed method of treating brewing yeast kaloids according to the invention by treating the treated yeasts with hot ethanol, which dissolves the bitter substances, reduces the nucleic acid content and desolvates the proteins, thereby actually preventing autolysis, thereby avoiding unpleasant flavor.

Odobraté kvasnice z pivovaru o sušině 12—14 % hmot. sa upravia prídavkom kyseliny ciitrónovej na pH 4,2-4,3 za stálého miešania a čerpajú sa do kolony proti prúdu 65—75 l0,C horúceho etanolu (96 '% obj.) v takom pomere, aby na 1 kg pivovarských kvasničných kalov přitékalo 2—2,5 1 etanolu. Doba zádrže v koloně má byť váčšia ako 40 min. Z kolony odohádza etanol zriedený vodou, ktorá sa nachádzala v kvasniciach a v ňom sú rozpuštěné horké látky, ako i dalšie cenné látky, ktoré je možné zužitkovat'. Z druhého konca kolony odchádaajú kvasnice s alkoholom. Desolvatováné kvasnice sa zhavujú alkoholu filtráciou a sušením až do 96 % hmot. sušiny. Suchý preparát sa halí a expeduje. Vyrobený preparát je svetloikrémovej farby, príjemnej chuti po tekvicových jadierkach, so sníženým obsahom nukleových kyselin, zbavený horkých látok, s plným obsahom vitamínov skupiny B. Přítomný etanol konzervuje výrobok.Taken yeast from brewery with dry matter 12–14% wt. were adjusted to pH 4.2-4.3 by the addition of ciitronic acid with constant stirring and pumped into a column of hot ethanol (96-% by volume) of 65-7510 , C in a ratio such that per 1 kg of brewer's yeast sludge 2 - 2.5 L of ethanol flowed in. The residence time in the column should be greater than 40 min. Ethanol, diluted with water present in the yeast, is discharged from the column to dissolve the bitter substances as well as other valuable substances which can be recovered. Yeast with alcohol is leaving the other end of the column. Desolvated yeast is compacted by alcohol filtration and drying up to 96% by weight. solids. The dry preparation is wrapped and shipped. The produced preparation is light-cream color, pleasant taste of pumpkin seeds, reduced nucleic acid content, free of bitter substances, full of vitamins of group B. Presence of ethanol preserves the product.

Z takto vyrobeného preparátu možno získávat B-komplex pre medicinálně účely, PANGAMÍN, zbavený inepríjemnej chuti a preparát sa mótže použiť taktiež ako fortifikant pre potravinářské ciele.The B-complex for medicinal purposes, PANGAMIN, devoid of unpleasant taste, can be obtained from the preparation thus prepared, and the preparation can also be used as a fortifying agent for food purposes.
