What can you tell us about the following ingredients and how they might ease processing and improve quality in high-end manufactured desserts?
Stabilizers for whipping and aeration, or perhaps freeze/thaw stability
Foam structures are held in place when air heated cells expand and egg proteins coagulate. Eggs naturally leaven but with a stabilizer like sodium lauryl sulfate, a whipping aid added to egg whites to produce more aeration and bubbles to bake around. Salt is a natural inhibitor of foam because of its ability to weaken protein bonds around the air cells. Sugar aids the foaming process but must be added carefully and at the right time for full volume to be achieved. Desserts contain functionality that support the control of water crystallization, water migration and only need in some cases a moisture retaining gum to hold minimize drying out over longer freezing periods.
Texturizers to maintain crumb quality or filling smoothness
To maintain crumb quality sugar, fat, and leavening aids are added to tenderize products. This is because they shorten gluten strands. Eggs tenderize because they provide aeration. These same items will also affect the texture by adding moisture to the crumb. Additives are sometimes added to flour to help control the outcome of the crumb. Oxygen is added to the flour to strengthen the gluten so that it will be more elastic. Potassium bromate is added to make a more elastic dough easier to handle once fermented; this product will produce a wider crumb when baked.
Starches, hydrocolloids and other ingredients for moisture management
Liquids from products like eggs, water and milk provide the moisture needed for the starch or hydrocolloid to activate and hydrate. The development of gluten maintains the moisture of the baked item.
Preservatives for microbial stability
Mold inhibitors are added to bread ingredients to prevent growth of spores especially when there is an increase in humidity or temperatures in the area. The use of mold and rope inhibitors is an extra precaution just in case the final baking does not kill any spores. Propionates are added to combat molds and rope bacteria. Calcium carbonate is added to the liquid and can be used to adjust the pH of a dough so that the likely hood of growth can be controlled. Invert sugar, salt and spices are often added to cookies or cakes to provide preservation as well.
Premade batters and mixes to ease production
Many shops are now using dry mixes with the addition of liquids, at their own ratio. This is because of the quality and the convenience the products provide is just as good as a fresh product. Most bakers will add their own enhancements to the mix. Normally all of the dry ingredients would be mixed together in the processes, so it does not hinder them to be combined beforehand.
