Yeasts are extremely versatile organisms that have accompanied humanity in the production of food and beverages for centuries. They are responsible for the fermentation process that transforms raw materials such as flour, fruit juice and malt into products such as bread, beer, wine and whiskey. In this article, we will take a closer look at the characteristics, properties and uses of yeast and find out when it is worth using preparations with them.
Yeast – what is it?
Yeasts are single-celled microscopic organisms belonging to the yeast fungi. The most popular species of yeast is Saccharomyces cerevisiae, but there are many other species that are used in various areas of food and industrial production. They are characterized by the ability to convert sugars into alcohol and carbon dioxide during the fermentation process.
Properties and uses of yeast
Yeast has many interesting properties that make them irreplaceable in the production of food and beverages. They are a source of B vitamins, such as vitamin B1 (thiamine), B2 (riboflavin) and B3 (niacin). Additionally, they contain large amounts of protein, which makes them a valuable dietary component.
In the food industry, yeast is used to produce bread, rolls, cakes, as well as alcohols such as beer, wine, whiskey and vodka. In medicine, yeast is used to treat certain fungal infections and as a dietary supplement due to its beneficial nutritional properties.
What is the difference between baking, brewing, wine and distilling?
There are many different types of yeast, tailored to specific uses. Baker’s yeast, as the name suggests, is intended for baking bread and confectionery. They are resistant to high temperature and salt, which makes them perfect for baking.
Brewery and wine yeast are used to produce alcoholic beverages. Brewer’s yeast converts sugars in beer, while wine yeast converts sugars in wine. They have different taste and aromatic characteristics that influence the final character of the drink.
Distiller’s yeast is used to produce stronger alcohols such as whiskey or vodka. They have the ability to convert more sugars into alcohol, which is necessary in the production of these drinks.
Yeast – nutritional values, vitamins, kcal
One teaspoon of dry yeast contains about 20-30 kcal, which makes it a low-calorie dietary component. They are a source of B vitamins, which play an important role in the proper functioning of the body. Additionally, yeast provides protein that is necessary for the construction and regeneration of tissues.
Yeast – where and what to buy? how to store? can yeast be frozen?
Yeast is widely available in grocery stores, both fresh and dry. When choosing yeast, it is worth paying attention to the expiration date and the type of yeast needed for a specific production.
Storing yeast is relatively simple. Dry yeast is best stored in an airtight container in a cool and dry place. Freezing yeast is not recommended as it may affect its quality.
Yeast preparations – when to use?
Yeast preparations can be used to supplement the diet with B vitamins and protein. They are especially recommended for people leading an active lifestyle, athletes, and vegetarians and vegans who may have difficulty obtaining the right amount of these ingredients in their diet.
Contraindications to consuming yeast
Although yeast is a valuable dietary component, some people may have contraindications to consuming it. People allergic to yeast fungi should avoid products containing yeast. Additionally, people with gluten intolerance should choose gluten-free yeast.
