Raman Spectroscopy Analysis in Food Testing

Raman spectroscopy is a molecular characterization technique based on Raman effect. The signal comes from the vibration and rotation of the molecule, and the food is nondestructive tested by analyzing the molecular structure in the tested food. The Raman spectrum can not only qualitatively analyze the chemical structure and chemical bond changes of the components contained in the tested substance, but also quantitatively detect the content of certain components of the food. The method can be applied to food composition detection, food authenticity and adulteration detection, pesticide residue detection, food additives and toxin detection. Principle of Raman Spectroscopy Analysis When the incident photons of monochromatic light interact with molecules, elastic collisions and inelastic collisions occur. There is energy exchange in inelastic collisions, which changes the movement direction and channel of photons. This scattering process is called Raman scattering. Raman scattering effect ...

Plant Metabolites for the Research of Plant Growth Regulators

Plant growth regulators are inspired by a class of plant metabolites called plant hormones. They can be extracted from plants or chemically synthesized. Most plant growth processes can be affected by plant growth regulators, such as flowering, fruit formation, ripening, fruit drop, and defoliation. Plant growth regulators are widely used in agriculture and horticulture to obtain specific advantages, such as decreasing susceptibility to biotic and abiotic stresses, improving morphological structure, increasing crop yield, and modifying plant constituent[1]. Applications Plant hormones are a class of plant metabolites , playing an unparalleled role in the agricultural field as plant growth regulators. Currently, a variety of plant growth regulators are synthesized based on the property of plant hormones. To a certain extent, farmers can control crop growth through plant growth regulators, which provides a breakthrough to solve the problem of world food shortages. The following are severa...

Properties of Titanium Dioxide

Image
  Introduction Titanium dioxide is a fairly new industrial product that gained importance only after the Second World War. Titanium dioxide has unique properties which make it an irreplaceable white pigment in the world today. It also known as the "king of white pigment". And the unique properties also make it widely used in most industrial production fields and people's daily life. Here, Alfa Chemistry will provide a comprehensive overview of the properties of titanium dioxide. Physical Properties Titanium dioxide is a white powder with relatively low density. It is insoluble in water, fat, organic acids and weak inorganic acids, slightly soluble in alkali and hot nitric acid and can dissolve in concentrated sulfuric acid. Among white pigments of the same quality, titanium dioxide has the largest surface area and the highest pigment volume. Titanium dioxide has good thermal stability with the melting point of 1830-1850 ℃ and boiling point of 2500-30006 ℃. At the same ti...

Roles of Astaxanthin

Astaxanthin is a ketocarotenoid derived from oxidation of β-carotene, naturally extracted from microalgae  Haematococcus pluvialis . Astaxanthin is a natural pigment that imparts a reddish-dark color to microorganisms and protects them from external factors such as oxidative damage and protection of cells from UV radiation. In addition, in recent years, astaxanthin has become an important biological indicator for food quality monitoring, and other effects of astaxanthin have also been extensively studied due to its attractive biological properties. To date, most of the health benefits of astaxanthin have been related to anti-cancer, anti-oxidant, anti-inflammatory (we have mentioned in " Health Benefits " and its subordinate pages). However, some pioneering studies have suggested roles of astaxanthin in other applications. Anti-diabetes Astaxanthin has also been shown to be effective against diabetes in obese animal models, including improving hepatic and skeletal muscle ins...
