Chemical and Biological Yeast in Low Carb – Hello, welcome to the Low Carb Diet Blog, and today we are going to learn a little about Chemical and Biological Yeast in the Low Carb Diet.
Chemical and Biological Yeast in Low Carb
Chemical and biological yeast – Just like bicarbonate, yeast plays a fundamental role in the preparation of low carb recipes, influencing the texture of food.
Yeast is a widely used ingredient in cooking. Thanks to it, we can taste soft, easily digestible and pleasant-tasting foods.
When it is added to the dough, several processes (chemical or biological) occur, which end up producing gaseous compounds.
These gases expand the dough of breads and cakes and create small holes, which makes it soft. The difference between chemical and biological yeast is in its composition: the chemical one is made up of sodium bicarbonate (NaHCO3); and the biological one has a yeast-type fungus.
Node chemical yeast, decomposition reactions occur when bicarbonate generates carbon dioxide and water, causing the mass to increase in volume.
This reaction is aided by the increase in temperature and only stops when all the yeast has reacted.
Biological yeast, in order to react, needs glucose, which feeds the yeast: the fungus ingests the glucose, and its metabolism transforms it into carbon dioxide and alcohol, which, with heat, expands the dough.
Because biological yeast is formed by a living organism, the conditions for producing the dough must be more controlled: the temperature, for example, must be between 30 and 50°C — this is why we let dough made with biological yeast rise before baking, while dough made with chemical yeast must go straight into the oven.
understand what Chemical and Biological Yeast is.
Chemical leavening agents are intended to be used in the preparation of special breads, cornbread, biscuits, cookies and similar confectionery products.
What is Chemical Yeast?
Chemical yeast is the product formed from a substance or mixture of chemical substances that, due to the influence of heat and/or humidity, produces gaseous release capable of expanding doughs made with wheat flour, low carb flour, starches or starches, increasing their volume and porosity.
It is composed of Acids, Bicarbonates, Carbonates, Dihydrogens, etc. in addition to substances suitable for food use, such as: sugars, flours, starches, enzymes, etc.
The label states the following recommendation: “Store away from moisture” or “Store in a dry environment”, or equivalent expressions, so do not place it in the refrigerator.
What is Biological Yeast?
Biological yeast or yeast is a living microorganism whose scientific name is Saccharomyces cerevisiae.
It is an essential ingredient in baking, as it is responsible for the rise of bread and pizza dough.
What is the difference between chemical and biological yeast?
Baking powder is responsible for the rise of cake batter, which occurs through a chemical reaction during baking.
Biological Yeast (tablet) promotes the growth of bread dough through fermentation that occurs before baking.
Yeast ingests the nutrients in the dough and, as a result, releases gases and aromatic substances, responsible for the volume, texture, aroma and flavor characteristic of bread.
For this reason, it is always necessary to let the dough rest after kneading and before putting it in the oven.
Tips for fresh yeast:
- Do not blend the yeast in a blender, as friction destroys the yeast.
- Prefer to buy the product close to its intended use and use it as soon as possible after purchase.
- Avoid placing yeast near strong smells, as yeast absorbs these odors.
- Because it does not contain preservatives and has water in its composition, fresh biological yeast is a sensitive product that requires care, especially in the summer.
- Store fresh biological yeast between 1 and 8ºC, the appropriate temperature and the main temperature responsible for preserving the product.
- Prefer to buy the product close to its intended use, as it is a perishable product.
Leave the product for purchase until the end of your shopping trip to avoid leaving it out of the refrigerator for too long. Yeast exposed to temperature variations has a reduced shelf life.
Do not freeze fresh yeast, as temperatures below zero damage the yeast cells and reduce their fermentative activity.
Always check the validity of the product before using it in the dough.
Do not blend the yeast in a blender, as the product's blade breaks the yeast cells, resulting in a loss of fermentative power.
Avoid placing yeast near products with strong odors, as yeast absorbs these odors.
Do not mix yeast directly with salt.
Prefer to buy fresh yeast in places with good storage conditions;
Always check the temperature where the product is displayed between 1 and 8ºC. If the display is not within the standard, inform the management of the location.
The best way to use Fresh Yeast is to dissolve it in half the amount of water that will be used in the recipe, or to crumble it over the dough. Then, simply mix until the dough is smooth.
