Enzymes are proteins found throughout nature. When one substance needs to be transformed into another, nature uses enzymes to speed up and control the process. This is catalysis, so enzymes are catalysts. Enzymes are also highly specific. Each one has a specific function; to break down a specific substance. This substance is the enzymes substrate. So the role of each type of enzyme in bread making depends on which substrate it works on. Amylases, for example, work on starch. Theyre one of the most widely used enzymes in bread making.

Enzymes are widely used in the baking sector. The first basic ingredient of cake is flour. On average, flour contains 82% starch, 12% protein and 3% fibre. Flour also contains natural enzymes in the presence of water. These are involved in the process by which the dough gets its proper consistency. These enzymes include amylases, which produce a substrate for the yeast enzymes that carry out alcoholic fermentation, proteases, which increase the volume of the dough, and xylanases, which increase the elasticity of the dough.
A major part of designing an enzyme system for a customer is to determine where this material is best needed. I think it is safe to say that in most cases it works during the preparation of the dough and perhaps also during the fermentation of the dough. That is when you will chop the small pieces of starch. But it actually only works if you take it out of the oven.
And over time, the larger starch molecules might crystallize or want to be reversed. But the small pieces of starch that you have created in the mixing process are still there and ready to prevent this crystallization. That is correct. The active effect of the enzyme occurs during the production of the dough. But the functionality occurs after baking.
That was one of the challenges in the premature release of the enzymes, because people dont know that something has happened in a ball and a fermentation process and whether it is deactivated. They do not want to activate the enzymes in the product after cooking.
Decades ago, people did not really know how and when to use them. Bakers have had many bad experiences by using either the wrong type of enzyme or too much of it. An extreme example is when you had to put too much amylase in your dough. This amylase would start to break down the starch in all directions. And you could end up with an almost liquid dough. So this is an extreme example of the excessive use of an enzyme. Most amylases available today are designed to be deactivated during baking.
There are many interactions between the different aspects of baking. This also applies to the way enzymes interact with baked goods. If I give you an example, there are several ways to influence volume. One of the enzymes we work with is a class of enzymes called proteases.

And instead of breaking down carbohydrates or starch, as we talked about amylase, the beet enzymes break down the protein, they break down the gluten. So they can weaken the gluten network. So if you have just the right amount of enzymes, you might be able to reduce the tension in the dough and make it rise a little more. So this is one possible approach.
Another approach would be to use an enzyme that produces carbohydrate fragments, so that the yeast can make use of its food and make the yeast more productive by producing more gas. And then you have more pressure to increase the volume. So I think what I am trying to say is that there are a lot of multiple interactions and we try to keep that in mind when we design an enzyme system.
Rarely do we design an enzyme system with one type of enzyme or one enzyme that is measured by trying to affect several functions simultaneously. And it depends very much on the specific application. It depends on the process used by the customer.
Because, you know, you cannot add more yeast, and adding more years is not the solution. So the solution that Aaron Clinton proposed was to add an enzyme to the clote, cut up the carbohydrates and give these foods more nutrition. We may have to turn more knobs than just providing carbohydrate fragments or yeast. We may also have to play with other features to make it a complete success. But yes, the logic you have set out is absolutely correct. It is the kind of thing where you can use an enzyme to solve a problem that you have here
Yes, it is very common for industrial bakers to face difficulties due to fluctuations in their flour supply. And they may have a recipe and a process that is set up in such a way that, for example, we develop a sub-rule that perfectly fills the dependencies of each one, perfectly shaped, in the whole tray. And then a new batch of flour arrives and suddenly the moulds are no longer full and the dough is too firm.
We are able to provide suppliers with formulated tools that allow them to modulate this extensibility to compensate for variations in their incoming flour. Sometimes we do this for a customer, and it only needs to be done once, and he is satisfied with the performance of his dough. In other cases, we have to show a baker how to use this particular tool and he adjusts the amount used when the type of flour changes.
We have ready-to-use products that customers can try to see if this solves their problem. But we are also happy to formulate a specific solution for them to do that. This specific solution means that you dont use the baking enzymes in every production. It would be in production. The dough seems to be more Buckie.
