Gelatin-based composite gels have been widely used in the food and pharmaceutical industries due to their versatile properties and ability to form gels at low temperatures. However, these gels often lack the desired rheological and textural properties. This study explores the incorporation of sesame seed oleosome-protein fillers as a novel approach to enhance the rheological and textural characteristics of gelatin-based composite gels. Through a comprehensive review of the literature, we delve into the properties of gelatin, sesame seed oleosomes, and the potential synergy between them, shedding light on the mechanisms responsible for the improved rheological and textural properties of the resulting gels. Composite gels play a significant role in the food and pharmaceutical industries. Gelatin, a widely used gelling agent, has been a popular choice due to its unique gelling properties. It forms gels at low temperatures, making it suitable for various applications. However, gelatin-based gels often lack the desired rheological and textural properties, which are crucial for the quality and acceptability of products. To address these limitations, researchers have explored the addition of fillers to improve the overall properties of these gels. This study focuses on enhancing the rheological and textural characteristics of gelatin-based composite gels by incorporating sesame seed oleosome-protein fillers. Gelatin is a protein derived from collagen, which is found in animal connective tissues. It consists of polypeptide chains with high levels of proline, hydroxyproline, and glycine, which provide its unique gelling properties. Gelatin molecules have a helical structure, which unravels upon heating, allowing them to form a network structure during cooling.

The field of organic synthesis has undergone a remarkable transformation in recent years, driven by the desire to develop more efficient and environmentally friendly methods for the construction of complex molecules. One of the key strategies in this quest is the use of asymmetric synthesis, which allows chemists to selectively produce a single enantiomer of a compound, avoiding the formation of unwanted byproducts and reducing waste. The asymmetric aldol reaction is a fundamental transformation in organic chemistry, and its development has been a central focus of research in the field. In recent years, biocatalysis has emerged as a powerful tool for achieving high levels of enantioselectivity in various chemical reactions. Enzymes, as nature's catalysts, are capable of catalyzing complex reactions with high specificity and efficiency. However, the application of enzymes in asymmetric synthesis has often been limited by the availability of suitable catalysts and the challenges associated with their screening and optimization. This article delves into an innovative approach, an easy bioprocess, for the screening and optimization of longchain peptide catalysts used in the asymmetric aldol reaction.

In a world grappling with environmental concerns and the need for sustainable practices, innovative methods for waste management and the production of valuable bioproducts are becoming increasingly significant. One such method involves the utilization of agricultural waste materials like potato and grape bagasse for the joint production of bacterial cellulose and gluconic acid in an airlift bioreactor. This approach not only helps reduce waste but also contributes to the production of biopolymers and organic acids with various industrial applications. The waste generated during food processing and agricultural activities is a substantial environmental concern. Among these waste materials, potato and grape bagasse hold particular promise due to their abundance and the potential they offer for value addition.

In the face of growing environmental concerns and the need for sustainable wastewater treatment methods, microalgae-based systems have gained increasing attention for their potential in removing pollutants from wastewater. Among the innovative approaches to harness the power of microalgae, porous substrate bioreactors have emerged as a promising technology. This article explores the possibilities and advantages of using microalgae in porous substrate bioreactors to address the critical issue of wastewater pollution. Wastewater pollution is a pressing global concern that impacts both the environment and human health. The discharge of untreated or poorly treated wastewater into rivers, lakes, and oceans can lead to the contamination of water sources, causing harm to aquatic life and posing serious health risks to those who depend on these water bodies for various purposes, such as drinking, agriculture, and recreation. Key pollutants in wastewater include organic matter, nitrogen compounds, phosphorus, heavy metals, and pathogens, all of which have the potential to wreak havoc on ecosystems and public health.
