Product Description

Sodium propionate is a common food additive that is industrially manufactured but also occurs in nature. Since it is toxic to mold and some species of bacteria, it is an especially effective additive in baked goods or other products that are susceptible to
spoilage.
Sodium propionate is an effective inhibitor of the growth of certain molds and some bacteria in bakery goods. It is usually
preferred in non-yeast leavened bakery products because the calcium ions' of calcium propionate interfere with the chemical
leavening agents. In those bakery products, such as cakes, tortillas, pie fillings etc., chemically leaved agents are used
(e.g.baking powder). sodium propionate is easy to handle and easy to incorporate into flour. It is a safe compound when
encountered at the low levels found in food.

Application
It is used as a masking agent in tanning to improve the alkali resistance of leather and the uniformity of tanning.

It is used in food industry as leavening agent, dough conditioner, buffer, tissue improver, curing agent, nutrient supplement, chelating agent, etc. If used as a leavening agent for baking products and pastries; Bread, biscuits assistant, buffer, pectin curing agent (gel action); Yeast food meat products tissue improvers, etc. Sodium propionate is used as a food preservative and anti-mold agent. It can be used alone or in combination with propionate and sorbic acid. Because it is alkaline, it is more suitable for pastry making than calcium propionate. Propionate is of great significance for the preservation of bread, pastries, biscuits and other baked foods, because the ionization is small, so it still has a good effect under alkaline conditions. Used for brewing, can increase the saccharification power, improve the fermentation capacity of beer; Used as a sticky substance printing preparation or feed additive.
