まとめ
オーム加熱(OH)はいんげん豆タンパク質(PP)の機能を改善し、泡立ち能力を高め、より柔らかいゲルを形成しました。この物理的修飾は、新しい植物ベースの食品原料の開発に有望です。
科学分野:
- 食品科学技術
- タンパク質化学
- 物理化学
背景:
- 植物由来タンパク質は、食品中の動物性タンパク質の代替としてますます使用されています。
- 市販の植物タンパク質原料は、加工による改変のために機能性が限定的であることがよくあります。
- えんどう豆タンパク質(PP)は、機能性食品用途の可能性を秘めた人気の植物タンパク質源です。
研究 の 目的:
- 市販のえんどう豆タンパク質(PP)の機能を強化するための物理的修飾法としてオーム加熱(OH)を調査すること。
- PPの物理化学的特性、泡立ち、乳化、ゲル化特性に対するOHの影響を評価すること。
主な方法:
- えんどう豆タンパク質分散液を100°C、130°C、150°Cでオーム加熱(OH)処理しました。
- 粒子径を含む物理化学的特性を測定しました。
- 標準的な方法を使用して、泡立ち、乳化、ゲル化特性を評価しました。
- ゲル化挙動を分析しました。
主要な成果:
- OHはPP粒子径を著しく減少し、より高い温度でより大きな減少を引き起こしました。
- 泡立ち能力は約40%増加し、安定した泡を形成しました。
- 乳化活性はOHによって実質的に強化されませんでした。
- OH処理PPは、未処理PPと比較して、より柔らかく、より均一なコールドセットゲルを形成し、複素弾性率の値は低くなりました。
結論:
- オーム加熱は、市販のえんどう豆タンパク質の機能特性を強化するための効果的な物理的修飾戦略です。
- OHはPPの泡立ち性能を向上させ、ゲル構造を調節し、新しい植物ベースの食品製品開発に適しています。

Non-ohmic Devices
1.5K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

Mechanical Protein Functions
5.6K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Proteins are the building block of life. They are also the most abundant macromolecules with as many diverse roles in the body. They are part of many structural components that provide unique shapes and structures to animal cells, tissues, and organs. In addition, they also act as biological catalysts and carry out several anabolic and catabolic reactions. Notably, some proteins are chemical messengers and regulate many critical processes, such as metabolism, growth, and development. They...

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
