What are the products of fermentation in yeast?

In this brief article, we will provide an answer to the question, “What are the products of fermentation in yeast?”. Furthermore, we will elaborate on the composition, benefits and types of fermentation products.

What are the products of fermentation in yeast?

The products of fermentation in Yeast are as follows.

• Alcohol
  
• Glycerol
  
• Carbon dioxide
  
• Cheese
  
•  Wine

Cheese

Cheese is the product of fermentation. It is available in different ranges of flavours and textures. While manufacturing yeast, acidification of milk is carried out. Coagulation is necessary to make cheese. Some enzymes of rennet and bacterial enzymes help in coagulation. 

There are numerous types of yeast. These yeasts are distinguished because of the type of milk, the content of butterfat and whether these are pasteurised or not. To enhance the flavour of cheese, some flavouring agents like herbs, spices and wood smoke are used.

What are the components of cheese?

Cheese is composed of water, fat, lactose and protein. All of these elements play a crucial role in the texture and flavour of the cheese. Out of these, casein protein is the most important one.

Types of cheese

Some types of cheese are as follows:

Soft cheese: Soft cheese is a cheese that has not attained maturity. These cheeses can be sold after maturation. Examples are Brie and Neufchatel.

Semi-soft cheese: The moisture content of semi-soft cheese is high. Its taste is not extreme but it is mild. Examples of semi-soft cheese are Port and Sault.

Medium-hard cheese: The texture of medium-hard cheese is semi-soft to hard. Bacteria provide aromatic and sharp flavour to these and provide their eyes. Examples include gouda and edam.

Hard cheese: The low moisture content helps to harden cheese. The packing time of hard cheese into moulds is more as compared to the soft cheese. An example of hard cheese is Cheddar. The curd of cheddar is cut, piled and is stirred before being pressed into forms.

Functions of cheese

• Cheese is very effective in the prevention of osteoporosis.
  
• Cheese helps to maintain the PH of the mouth and helps in saliva production. Due to these characteristics, it is helpful in the prevention of cavities.
  
• A sufficient amount of calcium is present in cheese. Calcium is very important to maintain vascular functions, in the secretion of hormones and to ensure smooth transmission of nerves. Calcium also helps to keep blood pressure in control.
  
• Cobalamin present in cheese helps in the production of red blood cells, proteins and DNA.
  
• Vitamin B12 also boosts mental health functions. Furthermore, anaemia, lethargy and muscle weakness can be treated by using Vitamin B12.
  
• The protein present in cheese helps to maintain the strength of bones. Protein is also essential for the strength of teeth. 

Glycerol

Glycerol is characterised by the presence of a simple compound known as a polyol. Glycerol has no colour and is an odourless, viscous liquid. The taste of glycerol is sweet and it is not toxic. Glycerides are the backbone of glycerol present in lipids.

While filming scenes in which water is involved, to stop areas from drying out, glycerol is used. Furthermore, it also helps in the generation of a smooth smoky environment.

Properties of glycerol

The melting point of glycerol is 17.8 degrees while its boiling point is 290 degrees centigrade. Due to the presence of these hydroxyl groups glycerol is hygroscopic. Glycerol can absorb moisture from the air. The solubility of glycerol is good in the water. This is because polyol groups of glycerol can form hydrogen bonds with water.

The density of the glycerol is a little bit high as compared to the density of water. Due to its high density, glycerol can be easily poured into a container of water. Over time, glycerol gains mild agitation and forms an aqueous solution.

Applications of glycerol

Some applications of glycerol are as follows.

• Glycerol is employed in the food industry as a humectant, solvent and sweetener. It also helps to preserve food. Glycerol also serves the role of the filling agent in low-fat foods whose production is carried out at the commercial level. 
  
• Due to antimicrobial and anti-viral properties, glycerol is used in the treatment of wounds. Glycerol has the potential to reduce inflammation.
  
• Propylene glycol and glycerol are the two main components of e-liquid solutions. This solution is used with electronic vaporizers.
  
• For automotive applications, glycerol serves the role of anti-freezing agent. The minimum freezing point of a glycerol-water mixture is more in comparison to an ethylene glycol-water mixture.
