초록

대두단백이 인체에 유익한 효과를 주는 양질의 단백질이라는 사실은 수많은 임상연구를 통해 검증됐다. 동물성 단백질의 높은 탄소발자국과 지속가능성에 대한 우려가 증가하고, 식물성 식품의 섭취를 늘릴 것을 권고하는 각국 보건당국의 움직임에 따라 식물성 단백질에 대한 수요가 증가하고 있다. 대두단백은 상용화된 식물성 단백질 중에서는 유일하게 완전단백질 식품으로 알려진 우유 및 달걀과 동등한 영양가를 갖는 단백질이다. 대두단백은 HDL콜레스테의 감소 없이 LDL 콜레스테롤, 총 콜레스테롤 및 중성지방을 감소시키는 효과가 있어 심혈관계 건강 증진에 도움을 주며, 동맥경화 진행을 늦추는 것으로 알려졌다. 대두단백은 다른 고품질 단백질과 마찬가지로 포만감을 증가시켜 체중 조절에 도움을 줄 뿐만 아니라, 체중 감소 시 실질체중(lean body mass) 보존을 도와 체성분 구성을 개선할 수 있도록 한다. 대두단백은 필수 아미노산의 적절한 공급을 통해 근육량을 보존시킬 뿐 아니라, 유청단백질과 카제인 등의 유단백과 함께 섭취함으로써 근육 성장을 더욱 촉진시키는 이점이 있다. 대두단백은 다양한 종류의 제품에 적용할 수 있다. 분산성, 유화 정도, 점도, 밀도, 겔 형성도 및 용해도를 조절한 다양한 분리대두단백 제품이 출시되었기 때문에, 원하는 조직감, 식감, 수화 정도 등에 따라 적절한 제품을 선택하여 적용할 수 있다. 이와 같은 장점 때문에 대두단백은 영양보충용 음료, 뉴트리션 바, 아이스크림 및 푸딩 등에 동물성 단백질의 대체재 혹은 보완재로 사용된다. 또, 대두단백은 육가공품 및 수산가공식품의 동물성단백질을 대체하여 경제적으로 제품의 품질을 향상시키면서도 본래의 식감을 유지할 수 있게 해준다. 마지막으로, 대두단백은 스낵, 시리얼, 음료, 파스타 및 간편식의 단백질 함량을 높이기 위해서도 널리 사용된다.

The rising global demand for food and beverages with higher protein content provides manufacturers with great opportunities for innovation and premium positioning of their products as healthy choices. However, the market price volatility and supply risks associated with animal-based proteins can quickly erode margins and profitability. A diversified protein strategy that includes plant-based soy protein greatly improves your ability to predict profitability over time, while maintaining or even improving product quality.
