DuPont dough strengtheners

ASCORBIC acid is an ingredient used by baking industry manufacturers to strengthen dough. It is usually sourced in China, where regulatory measures on environmental compliance and control are triggering price increases, shared DuPont.

Bakery manufacturers can also opt for substitutes to ascorbic acid including those offered by DuPont in its Hexose Oxidase portfolio. Unlike existing oxidative enzymes, the hexose oxidase technology present in the DuPont™ Danisco® GRINDAMYL™ SUREBake product range can utilise many different sugar molecules as a substrate rather than just glucose alone. There is an improvement in the gluten network in dough systems through oxidization during mixing and fermentation, forming stronger bonds between the gluten, thereby giving a better production with a drier dough and thus no stickiness issue.

The GRINDAMYL™ SUREBake product range can be used in any process where flour requires an extra oxidative effect to create the desired properties and improvement of flours. The Hexose Oxidase provides an excellent dough strengthening effect in the presence of oxygen and react with either mono or disaccharides – unlike glucose oxidase, which is more dependent on flour variations and procedures. Hexose oxidase has a strong affinity for its substrates, which makes it a powerful biological oxidant.

The strengthener can be used in various procedures and applications where a highly stable system is required. With the GRINDAMYL™ SUREBake product range, millers and bakers can expect to gain benefits in:

• Increased tolerance towards variations in processing parameters
• Reduced dough stickiness
• Increased water absorption
• Supplementation of chemical oxidants (including ascorbic acid, ADA etc)
• Improved shape and dimensions of the final bread product
• Increased bread volume

Manufacturers who have used a GRINDAMYL™ SUREBake product have seen improved bread quality in various applications. The strengthener can also be used in various procedures where a highly stable system is required, such as frozen dough.

“The price of ascorbic acid is still rising,” said Lee Lai See, Food Enzyme Business Director for ASPAC. “As many ASEAN manufacturers buy ascorbic acid from China, an increasing number of customers are switching to a GRINDAMYL™ SUREBake product fully or partially to buffer their cost. By using GRINDAMYL™ SUREBake, bakers will be able to reduce their production cost while maintaining the dough processability with improved baking performance such as better water absorption that result in bigger bread volumes.” she added.
