Description
(54) СПОСОБ ПЮИЗВОДСТВА МОЛОЧНОЙ СЫВОЮТКИ С ГИДЮЛИЗОВАННОЙ ЛАКТОЗОЙ(54) METHOD OF PULLOVER OF DAIRY WITH HYDULUSED LACTOSE
1one
Изобретение относитс к молочной про мьшшенности н предназначено дл использовани при переработке молочной сыворотки.This invention relates to the dairy industry and is intended for use in the processing of whey.
Известен способ превращени лактозы в глюкозу и галактозу в присутствий выделенного фермента - лактазы. Дл этого на безбелковой сыворотке выращивают дрожжи Sacchoromyces fragilis в течение 10-30 ч. Из дрожжей получают р-галактозндазу и используют дл гидролиза лактозы молочных продуктов (молока, сьшоротки) с последующей инактивацией фермента 1.A known method of converting lactose to glucose and galactose in the presence of the isolated enzyme lactase. For this, Sacchoromyces fragilis yeast is grown on protein-free whey for 10-30 hours. P-galactic dinase is obtained from yeast and used to hydrolyze lactose from dairy products (milk, short), followed by inactivation of enzyme 1.
Однако вьзделенный растворимый ферментный препарат это дорогосто щий катализатор , существенно вли ющий на себестоимость готового продукта, он неустойчив в растворах , требует сложных условий дл хранени .However, the isolated soluble enzyme preparation is a costly catalyst that significantly affects the cost of the finished product, it is unstable in solutions, and requires complex storage conditions.
Наиболее близким по технической сущнос ти и достигаемому положительному зффекту к предлагаемому вл етс способ производства молочной сыворотки и с пщролизованной лактозой, предусматривающий пастеризацию сыворотки, охлаждение ее до 30-32° С, доведений рН до оптимального значени 6,9-The closest in technical essence and achievable positive effect to the proposed is a method of production of whey and with schtrolizirovannogo lactose, involving pasteurization of the serum, cooling it to 30-32 ° C, bringing the pH to an optimum value of 6.9-
7,2, внесение дрожжей Sacchoromyces fragtlis дл экстракщш фермента (3-галактозидазы с последующим гидролизом сыворотки. По дан . ному способу дрожжи Saccharomvces fragilis в виде культурапьной жидкости или влажкой биомассы оживл ютс и наращиваютс в не больщом количестве сьгооротки в течение 24-48 ч. Полученна таким образом дрожжева закваска вноситс дл гидролиза лакто ,(, зы в молочную сыворотку. Дрожжевые клетки вьщел ют фермент Р-галактозндазу п среду н с его помощью гидролизуетс лактоза 121.7.2, application of Sacchoromyces fragtlis yeast for extracellular enzyme (3-galactosidase followed by serum hydrolysis. According to this method, Saccharomvces fragilis yeast in the form of a culture liquid or wet biomass is revived and increased in not large quantities at 48 The yeast starter obtained in this way is introduced to hydrolyze lacto, (, into the whey. Yeast cells digest the enzyme P-galactoscidase and hydrolyze lactose 121 with it.
Однако данный способ неприемлем дл JJ молочной промьпиленности, наращивание дрожжей дл гидролиза слишком трудоемко и длительно (их хранение невозможно даже в охлажденном виде более 24 ч.).However, this method is unacceptable for JJ milk production, yeast buildup for hydrolysis is too laborious and time consuming (their storage is impossible even in the cooled state for more than 24 hours).
Цель изобретени - упрощение процесса 20 и сокращение продолжительности получени . конечного продукта.The purpose of the invention is to simplify the process 20 and reduce the duration of receipt. the final product.
