Description

우유 단백질이 강화된 유음료 및 이의 제조 방법{Milk protein-enhanced drinks and a method for preparing the same}[0001] The present invention relates to milk protein-enhanced drinks and a method for preparing the same,

본 발명은 다량의 우유 단백질을 함유하는 유음료의 성상을 안정화시켜서 상온에서도 수 개월 동안 장기간 보관 및 유통할 수 있도록 하는 조성물 및 이의 제조방법에 관한 것으로, 다량의 우유 단백질이 함유되어 있는 유음료 및 레토르트(Retort) 멸균을 통하여 이를 제조하는 방법에 관한 것이다.
The present invention relates to a composition for stabilizing the characteristics of a milk fat containing a large amount of milk protein and allowing storage and distribution for a long period of time at room temperature for a long period of time and a method for producing the same. Retort) sterilization.

단백질은, 3대 영양 성분 중의 하나로서 생체 내 효소, 호르몬, 항체 등을 구성하여 생명 활동을 유지하며, 근육 등의 체조직을 구성한다. 이처럼 단백질은 생체를 구성하고 생체 내의 반응 및 에너지 대사에 참여하는 중요한 유기물로서, 최근 단백질에 대한 섭취에 대한 요구가 증가되고 있으며, 이에 따라 분말, 음료 등으로 그 형태가 다양화되고 있다(대한민국 공개특허 제2013-0097716호). 그러나, 단백질을 음료화하는 것에 있어, 온도 및 pH 등에 의하여 단백질이 변성되기 쉬워 응집, 침전 등으로 성상이 변하거나 쓴맛이 발현되어 관능의 어려움 등의 문제점이 있었으며, 이에 기존에는 고온의 열을 수 초 내지 수십 초 동안 유지하는 HTST(high temperature short time method) 및 UHT(ultra-high temperature sterilization) 살균방법을 통하여 수 주 동안 냉장 유통하는 제품을 개발하거나, UHT 멸균 후 무균 충진하여 수 개월간 상온 유통하는 제품에 한정되어 있었다.
Protein is one of the three major nutrients, which constitutes in vivo enzymes, hormones, and antibodies to maintain vital activities and constitute body tissues such as muscles. As such, proteins are important organisms that constitute the living body and participate in the reaction and energy metabolism in the living body. Recently, the demand for the protein has been increasing, and the forms thereof have been diversified into powder and beverage Patent No. 2013-0097716). However, in the beverage making of proteins, proteins are easily denatured by temperature, pH, etc., so that there are problems such as changes in properties due to coagulation and precipitation, and bitter taste is manifested, resulting in difficulty in sensory properties. (UHT) and UHT (ultra-high temperature sterilization) sterilization methods, which are maintained for a few seconds to several tens of seconds, or after UHT sterilization and sterilization, they are circulated at room temperature for several months It was limited to products.

이러한 배경 하에 본 발명자들은 즉시 마실 수 있는(ready to drink, RTD) 단백질 유음료로서, 다량의 단백질을 포함하면서도 레토르트(retort) 멸균 방식을 적용하여도 성상 안정화 및 관능이 우수하여 장기간 상온 유통이 가능한 음료를 개발하기 위하여 예의 노력한 결과, 유청단백질 및 카제인나트륨을 1 : 0.7 내지 1.5의 중량비로 포함하고, 특히 첨가제로서 구연산칼륨을 포함하는 유음료 조성물의 경우, 상기 중량비를 벗어난 조성물에 비하여 성상 및 관능 모두가 우수함을 확인하여, 본 발명을 완성하였다.
Under these circumstances, the inventors of the present invention have found that a ready-to-drink (RTD) protein milk beverage can be used as a beverage that can be distributed at room temperature for a long period of time even when a retort sterilization method is applied, It has been found that whey protein and casein sodium are contained in a weight ratio of 1: 0.7 to 1.5, and in particular, in the case of a milk or drink composition containing potassium citrate as an additive, both the properties and the sensory properties And the present invention was completed.

본 발명의 하나의 목적은 (ⅰ) 1 : 0.7 내지 1.5의 중량비의 유청단백질 및 카제인나트륨, 및 (ⅱ) 구연산칼륨을 포함하는, 우유 단백질이 강화된 유음료 조성물을 제공하는 것이다.One object of the present invention is to provide a milk protein enhanced milk protein composition comprising (i) a whey protein and a casein sodium in a weight ratio of 1: 0.7 to 1.5, and (ii) potassium citrate.

본 발명의 다른 목적은 (a) 무지방 우유 및 유청단백질을 포함하는 제1 혼합액; 유화제 및 지방을 포함하는 제2 혼합액; 물, 무지방 우유, 탈지분유 및 카제인나트륨을 포함하는 제3 혼합액; 및 안정제를 서로 배합하여 제1 배합액을 수득하는 단계; (b) 상기 (a) 단계에서 수득한 제1 배합액에 구연산칼륨을 혼합하여 pH 6.5 내지 7.5인 제2 배합액을 수득하는 단계; 및 (c) 상기 (b) 단계에서 수득한 제2 배합액을 멸균하는 단계를 포함하는, 우유 단백질이 강화된 유음료 조성물의 제조 방법을 제공하는 것이다. Another object of the present invention is to provide a process for producing a fermented milk, comprising: (a) mixing a first mixture liquid containing non-fat milk and whey protein; A second mixed liquid containing an emulsifier and fat; A third mixed liquid comprising water, skim milk, skim milk powder and sodium casein; And a stabilizer are mixed with each other to obtain a first blend liquid; (b) mixing potassium citrate with the first compounding liquid obtained in step (a) to obtain a second compounding liquid having a pH of 6.5 to 7.5; And (c) sterilizing the second blend liquid obtained in step (b). The present invention also provides a method for preparing milk protein-fortified milk beverage compositions.

본 발명의 또 다른 목적은 상기 방법으로 제조된 우유 단백질이 강화된 유음료를 제공하는 것이다.
Another object of the present invention is to provide a milk protein fortified with milk protein prepared by the above method.

상기의 목적을 달성하기 위하여, 본 발명의 하나의 양태는 (ⅰ) 1 : 0.7 내지 1.5의 중량비의 유청단백질 및 카제인나트륨, 및 (ⅱ) 구연산칼륨을 포함하는, 우유 단백질이 강화된 유음료 조성물을 제공한다.
In order to achieve the above object, one aspect of the present invention is a milk protein-enriched milk composition comprising (i) a whey protein and a casein sodium in a weight ratio of 1: 0.7 to 1.5, and (ii) potassium citrate to provide.

본 발명의 일 구현예에 따르면, 유청단백질 및 카제인나트륨이 1 : 0.7 내지 1.5의 중량비로 포함되는 경우, 성상 및 관능이 모두 우수한 유음료 조성물을 제조할 수 있다. 구체적으로, 유청단백질 및 카제인나트륨의 비율이 1 : 1.5를 초과하거나, 1: 0.7 미만인 경우에는 침전 및 응집 등이 발생하여 성상 면에서 부적합하다. According to an embodiment of the present invention, when the whey protein and sodium caseinate are contained in a weight ratio of 1: 0.7 to 1.5, a milk or drink composition having excellent properties and functionality can be produced. Concretely, when the ratio of whey protein to sodium caseinate is more than 1: 1.5 or less than 1: 0.7, precipitation and aggregation occur, which is unsuitable in terms of properties.

또한, 상기 유청단백질 및 카제인나트륨은 유음료 조성물 총 중량에 대하여 5 중량% 이하로 포함될 수 있으며, 구체적으로는 0.5 중량% 내지 5 중량%로 포함될 수 있으나, 이에 제한되는 것은 아니다.
The whey protein and sodium caseinate may be contained in an amount of 5% by weight or less based on the total weight of the composition, and may be 0.5% to 5% by weight, but are not limited thereto.

또한, 본 발명의 일 구현예에 따르면, 상기 비율로 유청단백질 및 카제인나트륨을 포함하는 유음료 조성물은 산도 조절제로서 구연산칼륨을 포함할 수 있다. Also, according to one embodiment of the present invention, the milk or milk composition containing whey protein and sodium caseinate in the above ratio may contain potassium citrate as an acidity controlling agent.

본 발명의 실시예에서는 산도조절제로서 탄산수소나트륨; 제이인산칼륨; 피로인산나트륨; 폴리인산나트륨; 및 구연산칼륨을 각각 사용한 결과, 다양한 산도조절제 중에서도 구연산칼륨을 사용하는 경우, 레토르트 멸균 후에도 분리 및 침전이 발생하지 않으면서 쓴맛이 거의 발현되지 않아 관능이 우수한 결과를 나타내었다. 따라서, 상기 비율의 유청단백질 및 카제인나트륨에 추가로 구연산칼륨을 사용함으로써 성상 및 관능이 우수한, 단백질 강화 유음료를 제조할 수 있다.
In the examples of the present invention, sodium bicarbonate as an acidity adjusting agent; Potassium phosphate; Sodium pyrophosphate; Sodium polyphosphate; And potassium citrate were used respectively. As a result, when potassium citrate was used among the various acidity regulators, separation and precipitation did not occur even after retort sterilization and the bitter taste was hardly expressed. Therefore, by using potassium citrate in addition to whey protein and sodium caseinate in the above ratios, protein-fortified milk beverages having excellent properties and excellent sensory properties can be produced.

상기 구연산칼륨은 C6H5K3O7·H2O의 화학식을 가지는 물질로서, 상기 유음료 조성물의 pH가 6.5 내지 7.5가 되도록 첨가될 수 있으며, 그 예로 상기 유음료 조성물 총 중량에 대하여 0.1 내지 1 중량%로 포함될 수 있다. 이러한 구연산칼륨의 첨가로 인하여 본 발명의 방법에 의해 제조된 단백질 강화 유음료는 열 및 pH에 의한 단백질 변성이 억제되는 효과를 가질 수 있다.
The potassium citrate is a substance having the formula C 6 H 5 K 3 O 7 .H 2 O and may be added so that the pH of the above-mentioned grocery composition is from 6.5 to 7.5. For example, 1% by weight. Due to the addition of potassium citrate, the protein-fortified milk beverage produced by the method of the present invention may have an effect of inhibiting protein denaturation due to heat and pH.

또한, 상기 유음료 조성물은 추가로 유화제, 안정제 또는 둘 다를 추가로 포함할 수 있다.
In addition, the milk or drink composition may further comprise an emulsifier, stabilizer or both.

그 결과, 상기 표 1에 나타낸 바와 같이, 유청단백질 및 카제인나트륨을 1 : 0.7 내지 1.5의 중량비로 포함하는 경우, 성상 및 관능 모두 우수한 유음료 조성물을 제조할 수 있음을 확인하였다. 특히, 첨가제로서 구연산칼륨을 사용한 경우, 탄산수소나트륨, 제2인산칼륨, 피로인산나트륨 또는 폴리인산나트륨을 사용한 경우에 비해 성상 및 관능을 모두 만족할 수 있음을 확인하였다.
As a result, as shown in Table 1, it was confirmed that when the whey protein and casein sodium were contained at a weight ratio of 1: 0.7 to 1.5, it was possible to produce a milk or drink composition excellent in both properties and sensory properties. Particularly, when potassium citrate was used as an additive, it was confirmed that both the property and the sensibility could be satisfied as compared with the case of using sodium hydrogencarbonate, potassium diphosphate, sodium pyrophosphate or sodium polyphosphate.
