What is Yeast Extract Used for?
Yeast extract is a concentrated liquid obtained by hydrolyzing and extracting yeast cells. It is rich in amino acids, nucleotides, vitamins and minerals. These ingredients give yeast extract its unique flavor and nutritional properties. Amino acids and nucleotides are key components in yeast extract and are responsible for enhancing the umami and savory flavors of food, thus improving the overall taste of the food.
In the food industry, yeast extract is often used as a flavoring agent to enhance and balance the flavor of food. It not only enhances the umami taste of food, but also provides strong umami flavor and aroma, making food more delicious. Due to its concentrated natural flavor substances, yeast extract is widely used in preparing various soups, sauces, and various foods such as meat products, breads, biscuits, and vegetarian products, giving these foods a richer taste and flavor. smell.
In addition, yeast extract is also regarded as a nutrient-rich food additive. It is rich in vitamin B complex and minerals, providing additional nutritional value to food. Therefore, yeast extract is not only a flavoring agent, but also a food additive that is rich in nutrients and plays a key role in the taste and flavor of food, providing a variety of uses and value to the food industry.
How Yeast Extract is Made？
The production process of yeast extract usually includes the following steps:
1. Cultivation of yeast cells: First, select a high-quality yeast strain and culture it in an appropriate medium to promote the reproduction and growth of yeast cells.
2. Harvest yeast cells: When the yeast cells reach the appropriate number and state, they are harvested, and the yeast cells are usually separated by centrifugation or filtration.
3. Hydrolysis: Harvested yeast cells undergo hydrolysis. This step is designed to break down the cell walls and release the nutrients within the cells.
4. Extraction: The hydrolyzed yeast cells are then extracted, usually using solvents or other extractants to separate and concentrate the required compounds, such as amino acids, nucleotides, etc.
5. Concentration: The extracted liquid is concentrated to remove excess water and obtain a concentrated liquid form of yeast extract.
6. Filtering and Refining: Finally, yeast extract may go through a filtration and refining process to remove impurities and further refine target ingredients, ensuring the purity and quality of the final product.
Through these steps, yeast extract is prepared, which is rich in nutrients such as amino acids and nucleotides and has unique flavor characteristics.
