- 食品科学と技術
- 材料科学
- 生物化学
背景:
- インテリジェントな包装は食品の保存期間を延長し,リアルタイムで品質を監視することを目的としています.
- キトーサンと高アミロースのトウモロコシは 生物分解性があり 薄膜を形成します
- フラボノイドのような植物由来化合物は,包装材料に機能的特性を与えることができます.
研究 の 目的:
- 牛肉の新鮮さを監視するために,Portulaca oleracea L.のフラボノイド (POF) を含むインテリジェントフィルムを開発する.
- チトザン含有量の高いトウモロコシ粉膜の物理的,機械的,熱的特性に対するPOFの影響を評価する.
- 貯蔵中の牛肉の腐敗指標の制御におけるフィルムの性能を評価する.
主な方法:
- 異なったPOF濃度でキトーサン濃度の高いトウモロコシ粉 (CA) マトリックスフィルムの製造
- 赤キャベツのアントシアニン (PCA) とカルキュミン (CR) を新鮮度モニタリングのための複合指標 (PC) として組み込む.
- 膜の特性:機械的 (伸縮強度,断裂時の伸縮),熱的 (融解温度),紫外線阻害 (透射性),牛肉の品質パラメータの監視 (pH,TVB-N,TBARS,色).
主要な成果:
- POFの組み込みにより,膜の機械的特性 (破裂時の延長,引力強度の低下) と熱安定性 (融解温度が163.23°Cまで上昇) が向上した.
- フィルムには紫外線を遮断する能力が向上し,透過性が低下した.
- 開発されたCA/PC/POFフィルムは,保存中の牛肉のpH,TVB-N,TBARS,および色の変化を効果的に遅らせ,新鮮さのモニタリングを示しました.
結論:
- インテリジェントなCA/PC/POFフィルムは 物理的・熱的性能を向上させています
- これらのフィルムは,肉製品のためのアクティブでインテリジェントな包装として大きな可能性を秘めています.
- この研究は,高度な食品包装ソリューションのための天然化合物の組み合わせの 連携的利益を強調しています.

Protein Digestion
86.3K
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.

Drugs for Treatment of Ulcerative Colitis in IBD
705
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Mechanical and Chemical Digestion in the Small Intestine
4.9K
The small intestine plays a crucial role in our digestive system, performing both mechanical and chemical digestion.
Mechanical digestion in the small intestine involves movements such as segmentations and migrating motility complexes (MMCs), primarily controlled by the myenteric plexus. Segmentations are localized contractions occurring in areas of the intestine distended by chyme—a mixture of partially digested food. These contractions mix chyme with digestive juices, facilitating...

Proteins: Dietary Sources and Requirements
2.2K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention
332
Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...
