Calcium propionate
$0.01
Calcium propionate is a food additive that is commonly used as a preservative to prevent the growth of mold and other microorganisms in various food products. It is the calcium salt of propionic acid and is often referred to by its chemical formula, Ca(C2H5COO)2. Calcium propionate is white crystalline powder or granules that are easily soluble in water. When added to food, it helps extend its shelf life by inhibiting the growth of bacteria, fungi, and molds, thereby preventing spoilage. It is commonly used in baked goods, dairy products, processed meats, and other foods where mold and bacterial growth are a concern.

Ammonium Lactate
Ammonium lactate is a combination of lactic acid and ammonium hydroxide. It's commonly used as a moisturizer to treat dry, scaly, itchy skin conditions, such as ichthyosis vulgaris and xerosis. The lactic acid component helps to exfoliate dead skin cells, while the ammonium hydroxide component helps to moisturize and soften the skin. It's available in various forms, including lotions and creams, and typically requires a doctor's prescription for use.
CarboxyMethyl Cellulose (CMC) Food grade
CarboxyMethyl Cellulose (CMC) Food grade is a water-soluble polymer that is derived from cellulose, which is a naturally occurring polymer found in plant cell walls. CMC is produced by chemically modifying cellulose through the addition of carboxymethyl groups, which gives it its unique properties such as high water solubility, thickening ability, and film-forming properties.
CMC is widely used in a variety of industries, including food, pharmaceuticals, cosmetics, and textiles, as a thickener, binder, stabilizer, emulsifier, and dispersant. It is commonly found in food products such as ice cream, salad dressings, and baked goods as a thickener and emulsifier, as well as in cosmetics and personal care products such as toothpaste and shampoo as a binder and stabilizer.
Corn Starch (food grade)
Corn Starch (food grade) is a fine, powdery substance derived from the endosperm of corn kernels. It is commonly used as a thickening agent in cooking and baking, as well as in other industries such as papermaking, textiles, and adhesives. Corn starch has a neutral flavor and a translucent appearance when mixed with liquid, making it a versatile ingredient in many recipes.

High gluten wheat flour
High gluten wheat flour refers to varieties of wheat that contain a higher proportion of gluten proteins compared to other wheat varieties. Gluten is a complex mixture of proteins found in wheat and other grains such as barley and rye. It provides elasticity and structure to dough, making it important for baking purposes.
High gluten wheat is typically preferred for making bread and other baked goods that require a strong, chewy texture and good rise. The increased gluten content in high gluten wheat results in a higher protein content, particularly in the form of glutenin and gliadin proteins, which contribute to the formation of gluten when mixed with water.
The elevated gluten levels in high gluten wheat allow for better gluten development during the dough formation process, resulting in bread with a desirable texture and volume. The enhanced elasticity and strength of the gluten network in high gluten wheat contribute to the retention of gas bubbles during fermentation, leading to a more substantial and well-risen final product.
Tetrasodium EDTA
Tetrasodium EDTA , also known as ethylenediaminetetraacetic acid tetrasodium salt, is a chemical compound commonly used in various industrial and commercial applications. It is a chelating agent, meaning it has the ability to bind and capture metal ions, thus preventing them from reacting with other substances or causing unwanted effects.
A concise definition of tetra sodium EDTA would be:
"Tetra sodium EDTA is a water-soluble salt derived from ethylenediaminetetraacetic acid, used as a chelating agent to bind and sequester metal ions, serving purposes such as metal complexation, stabilization, and preventing undesired chemical reactions."
