What are Succinylated Monoglycerides ?
Succinylated Monoglycerides are additives used as emulsifiers, dough conditioners and crumb improvers in baked goods and shortenings. They are available in powder form, which is insoluble in cold water but dissolves in hot water and alcohol. Their HLB value ranges from 5-7.1
In the baking industry, succinylated monoglycerides are used in the production of yeast- and chemically-leavened products including:1
The development of emulsifiers evolved in parallel to shortenings for baking purposes and the advancement in lipid chemistry.1
Succinylated monoglycerides are obtained from fats and oils through a succinylation reaction. In the US alone around 500,000 pounds of emulsifiers are used in the food industry, with the baking industry accounting for about half of the emulsifiers market.1
Succinylated monoglycerides have wide variety of functions in baked goods, some of which are:1
- Dough conditioning: increases mixing and dough mechanical stress tolerance
- Dough strengthener: improves gas retention and loaf volume
- Crumb softening: retards crumb hardening by decreasing free amylose
- Prevents staling: due to the retardation of starch retrogradation
- Blending: assist in blending and emulsification of ingredients
- Enhance shortening properties
- Moisture retention: shelf life extension
- Improves quality: aids the quality of baked goods production and compensates for variations in raw materials
- Increased aeration
Emulsifiers such as succinylated monoglycerides can significantly reduce non-waxy starch digestibility, thus reducing its glycemic index.3
Succinylated Monoglycerides are manufactured through the reaction of a distilled monoglyceride with succinic anhydride at a temperature range of 80-180 °C (175-350°F).3 At temperatures below 95°C (<200°F) an alkaline catalyst may be required to accelerate the reaction. However, at higher temperatures no catalyst is required.3
Succinylated Monoglycerides must meet the following specifications according to the FDA:
|Succinic Acid||14.8 – 25.6 %|
|Melting Point||50-60 °C (122 – 140 °F)|
A wide range of baked goods include succinylated monoglycerides. This emulsifier has an HLB range from 5-7, giving it a lipophilic nature. It is best used after dissolving it in the shortening or lipid phase of the baked good before mixing with the rest of the ingredients.
The following table shows usage limits, benefits and drawbacks of using succinylated monoglycerides in baked goods:1
|Yeast-raised products||0.5%||Dough conditioningCrumb improvingVolume and texture Reduced staling||Less effective volume improver than other monoglycerides|
|Cakes||0.5%||AerationEmulsificationCrumb softening||Less common than PGME* and SSL.**|
|Cookies and crackers||0.5%||Controls spreadImproves cuttingImproves texture||Provides less spread than SSL.|
*PGME: propylene glycol monoester
** SSL: Sodium Stearoyl Lactylate
Succinylated Monoglycerides can be safely used in foods providing they meet the FDA specifications. They can only be used in shortening as an emulsifier (≤ 3%) and in bread baking (≤ 0.5%) as a dough conditioner.4
They are not currently approved in the European Union, however they have an assigned E number, E 472g.5
