Description

本発明は、乳清を用いた乳清食品およびその製造方法に関する。   The present invention relates to a whey food product using whey and a method for producing the same.

乳清は、牛乳からカゼインを除いて得られ、β−ラクトグロブリン、α−ラクトアルブミン、血清アルブミンなどのタンパク質を含み、栄養価に富んでいる。
従来、改良した乳清の製造方法として、乳清をナノフィルトレーションにより脱塩処理した後、乳糖分解酵素で乳糖分解処理する乳糖分解脱塩乳清の製造方法がある(例えば、特許文献1参照)。
Whey is obtained by removing casein from milk and contains proteins such as β-lactoglobulin, α-lactalbumin, and serum albumin, and is rich in nutritional value.
Conventionally, as an improved method for producing whey, there is a method for producing lactose-degraded desalted whey in which whey is desalted by nanofiltration and then lactose-decomposed with lactose-degrading enzyme (for example, Patent Document 1). reference).

特開2004−129579号公報JP 2004-129579 A

しかしながら、特許文献1に示す従来の技術では、製造される乳清は、食品の物性を改良するために食品の原料に用いられるだけで、そのまま食されるものではなく、用途が限定されていた。また、クリームチーズなどナチュラルチーズの製造の際に発生する乳清は、飼料等に利用される以外は産業廃棄物として廃棄されていた。このように、従来、貴重なタンパク資源である乳清の有効利用が図られないという課題があった。   However, in the conventional technique shown in Patent Document 1, the produced whey is only used as a raw material for food in order to improve the physical properties of the food, and is not eaten as it is, and its use is limited. . In addition, whey generated during the production of natural cheese such as cream cheese has been discarded as industrial waste except for use in feed and the like. Thus, conventionally, there has been a problem that effective utilization of whey, which is a valuable protein resource, cannot be achieved.

本発明は、このような課題に着目してなされたもので、乳清の用途を広げ、その有効利用を図ることができる乳清食品およびその製造方法を提供することを目的としている。   This invention was made paying attention to such a subject, and it aims at providing the whey food which can expand the use of whey and can aim at the effective use, and its manufacturing method.

上記目的を達成するために、本発明に係るジャム状の粘着性を有する乳清食品の製造方法は、生乳と生クリームとを混合した調整乳を殺菌、冷却した後、23℃で16時間乳酸発酵させ、発酵により凝固したカードと乳清とに分離し、分離した乳清を限外濾過膜で3倍に濃縮し、膜非透過の濃縮液に乳糖分解酵素を加えて乳糖を分解し、その酵素分解液に糖類およびクリームを混合し、真空濃縮機により3〜3.5倍に濃縮して成ることを特徴とする。
本発明に係る乳清食品の製造方法では、前記酵素分解液に前記糖類とともにクリームを混合した後、濃縮および殺菌する。この場合、前記濃縮および前記殺菌を真空濃縮機によりメイラード反応を起こさない低温で行う。
本発明に係る乳清食品は、前述の乳清食品の製造方法により製造されたことを特徴とする。
In order to achieve the above object, the method for producing a whey food product having jam-like adhesiveness according to the present invention comprises sterilizing and cooling adjusted milk in which raw milk and fresh cream are mixed, and then lactic acid at 23 ° C. for 16 hours. Fermented, separated into curd and whey coagulated by fermentation , concentrated the separated whey three times with an ultrafiltration membrane, added lactose-degrading enzyme to the membrane-impermeable concentrate, decomposed lactose, The enzyme decomposition solution is mixed with sugar and cream, and is concentrated 3-3.5 times by a vacuum concentrator .
In the method of manufacturing the whey food according to the present invention, after mixing the cream with the sugar in the enzyme hydrolyzate was, you concentration and sterilization. In this case, it intends row at a low temperature that does not cause a Maillard reaction by vacuum condenser the concentration and the sterilization.
The whey food according to the present invention is manufactured by the above-described method for manufacturing whey food.

乳の乳酸発酵は、生乳と生クリームを混合した調整乳を用い、殺菌、冷却した後、23℃前後で約16時間発酵させる。発酵により凝固したならば、攪拌しながら加熱し、カードセパレーターもしくは濾過布等によりカードと乳清とに分離する。 Lactic acid fermentation of milk, using the adjustment milk mixed with milk and cream, sterilized, cooled, Ru is approximately 16 hours fermentation at about 23 ° C.. When solidified by fermentation, the mixture is heated with stirring and separated into curd and whey by a card separator or a filter cloth.

乳清の濃縮は、限外濾過膜による濾過または真空濃縮機により行うことが好ましく、特に、限外濾過膜により濾過した膜非透過の濃縮液に乳糖分解酵素を加えて乳糖を分解した後、真空濃縮機によりさらに濃縮を行うことが好ましい。限外濾過膜による濃縮では、3倍程度に濃縮することが好ましい。乳糖分解酵素(ラクターゼ)を加えて乳糖を分解することにより、製品の舌触りを改良することができる。乳糖分解酵素の添加量は、膜非透過の濃縮液に対し0.005乃至0.01重量%が好ましい。乳糖の分解は、膜非透過の濃縮液を50℃前後を保持しながら20時間攪拌を続けて行うことが好ましい。乳糖の分解後は、直ちに5℃以下まで冷却することが好ましい。   Concentration of whey is preferably performed by filtration through an ultrafiltration membrane or by a vacuum concentrator. Further concentration is preferably performed by a vacuum concentrator. Concentration with an ultrafiltration membrane is preferably about 3 times. By adding lactose-degrading enzyme (lactase) and degrading lactose, the touch of the product can be improved. The amount of lactose-degrading enzyme added is preferably 0.005 to 0.01% by weight based on the membrane-impermeable concentrate. Lactose decomposition is preferably carried out by continuously stirring the membrane-impermeable concentrate at around 50 ° C. for 20 hours. It is preferable to immediately cool to 5 ° C. or less after the decomposition of lactose.

真空濃縮機による濃縮では、酵素分解液に糖類とともにクリームを混合することにより、風味を調整することができる。真空濃縮機による濃縮は、メイラード反応を起こさない低温、特に50℃前後の温度で行うことが好ましい。真空濃縮機による濃縮では、3〜3.5倍程度に濃縮することが好ましい。殺菌は、濃縮後、75℃前後の温度で加熱して行うことが好ましい。   In concentration using a vacuum concentrator, the flavor can be adjusted by mixing cream with saccharides in the enzyme decomposition solution. Concentration by a vacuum concentrator is preferably performed at a low temperature that does not cause the Maillard reaction, particularly at a temperature around 50 ° C. In the concentration by the vacuum concentrator, it is preferable to concentrate to about 3 to 3.5 times. The sterilization is preferably performed by heating at a temperature of about 75 ° C. after concentration.

濃縮および殺菌後、例えば、ホッパーにより瓶詰めまたはパック詰めにして出荷することができる。
製品は、ジャム状であってパンなどに塗って食べたり、コンデンスミルクの代わりとしてイチゴなどに掛けたりして食べるのに適している。
After concentration and sterilization, it can be shipped, for example, bottled or packed with a hopper.
The product is jam-like and is suitable to be eaten by applying it on bread or by hanging on strawberries instead of condensed milk.

本発明によれば、乳清の用途を広げ、その有効利用を図ることができる乳清食品およびその製造方法を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the use of a whey can be expanded and the whey food which can aim at the effective utilization and its manufacturing method can be provided.

以下、本発明の実施例について説明する。
生乳90重量%とクリーム10重量%とを混合した調整乳の均質化を行い、71℃15秒殺菌を行った後、23℃まで冷却した。これに市販の乳酸菌を0.6重量%添加し、23℃で16時間発酵させた。発酵により凝固したものを攪拌しながら加熱し、カードセパレータによりカードと乳清とに分離した。
Examples of the present invention will be described below.
The prepared milk mixed with 90% by weight of raw milk and 10% by weight of cream was homogenized, sterilized at 71 ° C. for 15 seconds, and then cooled to 23 ° C. To this, 0.6% by weight of a commercially available lactic acid bacterium was added and fermented at 23 ° C. for 16 hours. What was coagulated by fermentation was heated with stirring and separated into curd and whey by a card separator.

乳清を限外濾過膜で3倍に濃縮した。その濃縮液に対し0.005重量%の乳糖分解酵素を添加し、50℃前後を保持しながら20時間攪拌を続け、乳糖を分解した。乳糖の分解後、直ちに5℃以下まで冷却した。   The whey was concentrated 3 times with an ultrafiltration membrane. 0.005% by weight of lactose-degrading enzyme was added to the concentrated solution, and stirring was continued for 20 hours while maintaining the temperature around 50 ° C. to decompose lactose. Immediately after the decomposition of lactose, it was cooled to 5 ° C. or lower.

乳糖を分解した濃縮液82重量%、砂糖15重量%、クリーム3重量%を混合して風味を調整した。次に、真空濃縮機により50℃で低温濃縮を行い、3.25倍に濃縮した。濃縮終了後、75℃で加熱、殺菌した。こうして、ジャム状の乳清食品を製造した。乳清食品は、ホッパーにより、一般販売用のものは150g容量のガラス瓶に瓶詰めし、業務用のものは20kg容量のポリ容器に充填した。   The flavor was adjusted by mixing 82% by weight of concentrate obtained by decomposing lactose, 15% by weight of sugar and 3% by weight of cream. Next, low-temperature concentration was performed at 50 ° C. with a vacuum concentrator, and the solution was concentrated 3.25 times. After completion of concentration, the mixture was heated and sterilized at 75 ° C. Thus, a jam-like whey food was produced. Whey foods were bottled in a 150 g capacity glass bottle for general sales by a hopper and in a 20 kg capacity plastic container for business use.

製造した乳清食品は、淡い酸味を有し、ジャム状の粘着性を有し、パンに塗って食べたり、イチゴに掛けて食べたりするのに適していた。
The manufactured whey food had a light acidity and had a jam-like tackiness, and was suitable for being applied to bread or eating on strawberries.
