Chemical Substances Used in Food
Definition: Chemical substances are compounds intentionally added to food to alter its properties, such as flavor, texture, or shelf life.
Regulation: The use of chemical substances in food is regulated by government agencies, such as the FDA in the United States, to ensure the safety and well-being of consumers.
Types: Chemical substances used in food include:
- Food additives: Enhance flavor, texture, color, or nutritional value.
- Processing aids: Assist in food manufacturing, but are not intended to remain in the final product.
- Colorants: Provide or restore color.
- Preservatives: Extend shelf life by inhibiting microbial growth.
- Stabilizers and thickeners: Alter texture and mouthfeel.
- Antioxidants: Prevent oxidation and rancidity.
Molecule Structure of Water
Water is a molecule composed of two hydrogen atoms and one oxygen atom (H2O). The molecule has a bent shape, with the oxygen atom at the center and the hydrogen atoms bonded to it at an angle of about 104.5 degrees. The molecule is polar, meaning that it has both positive and negative charges. The positive charges are located on the hydrogen atoms, and the negative charges are located on the oxygen atom. The polarity of the water molecule is due to the difference in electronegativity between oxygen and hydrogen. Oxygen is more electronegative than hydrogen, meaning that it attracts electrons more strongly. This results in the electrons in the water molecule being pulled towards the oxygen atom, and away from the hydrogen atoms.

Materials Science for Beginners
Materials science is the study of the properties and behavior of materials, including their structure, composition, and bonding. It is an interdisciplinary field that draws on principles from chemistry, physics, and engineering.
Key Concepts in Materials Science:
- Atoms and Molecules: Materials are composed of atoms and molecules, which are organized in different ways to form different types of materials.
- Bonding: Atoms and molecules are held together by various types of bonds, including covalent bonds, ionic bonds, and metallic bonds.
- Structure: The arrangement of atoms and molecules in a material determines its structure, which can be crystalline (ordered) or amorphous (disordered).
- Properties: The properties of a material, such as strength, hardness, electrical conductivity, and thermal conductivity, are influenced by its structure and bonding.
