Propylene Glycol, A Food Additive That Has Recently Fallen Into The Cusp Of Baking Circles
Jan 22, 2021
Propylene glycol should not be unfamiliar to friends in the additive industry, but propylene glycol entered the food industry as a food additive in 2012, so many friends in the baking industry don't know much about it. So what is propylene glycol? In fact, propylene glycol is a food additive prepared by direct hydration with propylene oxide and water as raw materials.
With the improvement of food laws and regulations and the strengthening of supervision, more and more food additives are included in the scope of mandatory inspection, such as the conventional chemical preservatives sodium dehydroacetate, potassium sorbate, calcium propionate, natural preservatives sodium Tammycin, etc., now also includes propylene glycol. Then the editor of Baiqing will show you how to use propylene glycol in a standard way to avoid exceeding the standard.
You can see from the above table:
1. Propylene glycol as a food additive can only be used in pastries in bakery products, such as cakes, cakes and other products belonging to the category of pastries, and the maximum use amount shall not exceed three thousandths.
2. It is inevitable to add some flavors in the production process of the product. Generally, propylene glycol is used as the solvent and carrier in liquid flavors, so what should be paid attention to?
① In terms of addition and use, try to avoid adding non-cake products, such as bread. Although this is in line with the principle of bringing in, the food flavors can only be marked as edible flavors in the food label, and the ingredients in the flavors cannot be reflected, so when detected When using propylene glycol, it is impossible to appeal. (This is the current situation, see if there are related regulations to be adjusted in the future)
② When using in pastries, pay attention to the total amount of propylene glycol added to the amount of liquid flavor, although there will be baking loss, but the boiling point of propylene glycol is 188.2 ℃, the core temperature of the product is far from reaching, so the baking loss of propylene glycol It is not as big as drinking water, so be careful when using it.
3. Propylene glycol is also contained in some emulsifying additives, such as cake oil, bread emulsifier, etc. Therefore, in the selection of compound emulsifiers, use emulsifiers that do not contain propylene glycol as much as possible to avoid illegal use.
