Natural Additive for Animal Feed

Based on the Schinopsis Balansae type of Quebracho Colorado, especially developed as an additive for animal feed (ruminants), It is a tannin obtained in a pure state with only 1.2–1.4 % ash content, which shows that the present salts are only those typical of wood in its natural state. Due to the special extraction conditions (pressure and temperature) and its subsequent physical treatment, MGM-S is food grade.Quebracho Colorado wood is chipped at a specific granulometry and subjected to steam and water extraction at selected pressure and temperature. This tannin liquor is subsequently concentrated in vacuum and subjected to a process which ensures a suitable molecular weight range to achieve the properties which differentiate MGM–S from the quebracho extracts used in other applications. There is no addition of chemicals or animal products, and temperatures ensure total asepsis of the product throughout the process.”

Propyl gallate

Propyl gallate is the common name of propyl 3,4,5-trihydroxybenzoate. It is formed by the esterification of gallic acid with propanol.

It is a natural product used as food-grade antioxidant for fats and oils in general, and food and cosmetics containing them; in emulsions, waxes, transformation products, fish meal for pets, potato chips, chewing gums, toothpaste, packing materials and others. It also inhibits the auto-oxidation of paraldehyde and similar substances exposed to peroxides in the presence of oxygen. Propyl gallate may be combined with other anti-oxidant products such as BHT, BHA and ascorbyl palmitate. It may be used to deactivate the presence of metallic traces (iron and copper) when combined with citric acid, which acts as a quelant to avoid unwanted colors.

Limit or tolerance: 0.02% (200 ppm) alone or combined, based on total content of fats or oil in the product.

The use of propyl gallate as anti-oxidant in human and pet food is subject to specific rules in each country.
