What is the Use of Sodium Hydroxide in Food Processing？

Sodium hydroxide in food processing is a broad and complex subject. Sodium hydroxide food processing is the first step in a long production process. This article will take a brief look at how sodium hydroxide is used in food processing, as well as what it does to alter the food product. But here are some of the basics:

1.Sodium hydroxide is often used as a leavening agent in breads

This is one of the most widely used applications of sodium hydroxide as a food processing ingredient in breading and dough processing. In the dough, it acts as a binder so that a dough can be pulled, shaped, and baked like an ordinary bread. In flour and other dry ingredients, it is used as a filler to increase bulk and to improve quality of the raw materials.

2.Sodium hydroxide can be also used as a food preservative.

This is because of two reasons, firstly, it is an anti-microbial food additive. Sodium hydroxide usually used in preserves to control acidity and prevent mold growth. Secondly, sodium hydroxide is a binding agent that facilitates the solidification of food products such as candies or syrups.

3.Sodium hydroxide can also be used in food packaging

Sodium Hydroxide can be found in several food packaging materials. This is because it can be used to make plastic resins that are highly resistant to water and other elements. These resins are used to coat or line steel cans for foods such as baked beans and soups among others.

4.Alkalizing beverages.

This is because sodium hydroxide is a basic substance and therefore have the ability to neutralize acids. In commercial soft drinks and bottled mineral water, sodium hydroxide is used to give the product an alkaline pH. This changes the taste.

5.Cheese processing

Sodium hydroxide in food processing like cheese. Sodium Hydroxide is often added in powdered milk to create cheese curds and other dairy products such as cottage cheese. The modification of pH using sodium hydroxide will change the physical structure of casein proteins, making them soft enough for cutting, shaping or twisting for convenience purposes when making cheese on a commercial scale.

6.Sodium hydroxide is also used in the production of artificial metallic honey.

This is because sodium hydroxide can break down the complex sugars and proteins in honey, allowing you to make a syrup-like substance from regular sugar or honey. This has a huge advantage because it allows one to produce an identical product without using any natural ingredients such as bees or flowers. It also reduces cost of production and increase profit margin.

7.Sodium Hydroxide has been widely used in the manufacturing of bio-ethanol in third world countries.

This is mainly because it can be used as an alternative to scarification which could lead to contamination and a low production yield. This makes sodium hydroxide one of the most environmentally friendly additives for ethanol production.

What are the sources of Sodium hydroxide

Sodium hydroxide is commercially prepared from mined or seawater sodium chloride (NaCl) and washing soda or ammonia.

Mined sodium chloride can also come from hydrochloric acid. Ammonia is obtained as a by-product when coal or natural gas is processed and fuels are made. The washing soda is produced by treating the ammonia with carbon dioxide to produce sodium carbonate. Methane gas, or natural gas, can be used to produce washing soda in some areas of the world.

World production of sodium hydroxide was about 1 million tonnes for 2003 with about 80% coming from washing soda and 20% from synthetic sodium chloride containing more than 5% NaOH and moisture. About 90% of the sodium hydroxide is used for food processing and about 10% for industrial uses.

Sodium hydroxide is the most commonly used chemical in the world in soft drink manufacturing, and because of this, it is a common by-product that can be disposed of in a number of mediums.

The fate of sodium hydroxide after production varies depending on its application. The overall process looks like: In food processing; sodium hydroxide reacts with protein during pH adjustment (which alters how sensitive the food will be to microorganisms), as well as forming an insoluble precipitate when it is cooled, releasing free carbon dioxide. Sodium hydroxide in food processing. Additional impurities are removed by filtering. The liquid that is left after filtration is sent to the storage tank where it will wait to be used in other food products. The sodium hydroxide can either be disposed of in the air or water, but additional experiments need to be done to determine the best method since sodium hydroxide is caustic and corrosive; therefore, it can not just be dumped into a lake, sea, or somewhere else untreated.
