Preparation of Effective Immobilized Lipases for the Green Production of Aroma Esters for Food Industry
Project no. 22632 · Status: Kapanmış (Yayın bekleniyor) · 2021
Summary
<p>The billion-dollar flavor industry impacts many aspects of people's daily lives around the world. The industry has become a part of daily life with a wide variety of products such as toothpaste, coffee, tea, deodorant, ice cream, lipstick and perfume. A report on the market stated that consumers interact with the products of this industry 20-30 times a day. The sector's market is rapidly increasing with the demand for processed foods and personal care products. The world market share of aroma compounds in 2018 was evaluated as approximately 20 billion dollars and is expected to reach 38.56 billion dollars in 2026 with a growth rate of 4.7%.</p><p>Most aroma compounds occur naturally in plant sources, and the oldest method used for their production is their extraction from the plant source in which they are found. However, the extraction of these substances from the sources where they are found in low concentrations, is far from meeting the need for these compounds used in various sectors. For this reason, today they are largely produced through chemical synthesis. However, regulations made in international legislation, conscious consumption preferences and the negative effects of chemical synthesis processes on health and the environment have shifted interest to processes for obtaining natural products in recent years. Only products obtained by extraction from the source or produced by biotechnologically (using enzymes, microorganisms or tissue cultures) can be labeled as natural.</p><p>In this project, it is aimed to prepare effective immobilized lipase forms for the enzymatic production of some aroma esters especially used as additives in the food industry. In this manner, ester synthesis capability of catalysts that immobilized by different strategies were tested in organic solvent environment. Conditions for immobilization and reaction conditions for ester synthesis were optimized. Characterizations studies were performed for free and immobilized lipases.</p>
