Introduction This note explains briefly what is meant by cleaning, why it is necessary in the fish industry, and what cleaning materials and equipment are available for different jobs. The main types of detergents and sterilizers are described, and some advice is given on the selection and use of cleaning agents for the removal of the many kinds of dirt that are typically encountered in fish processing. In the food industry, cleaning is one of the commonest, and certainly one of the most important, operations. In the fish industry, cleaning in the past has almost always been done by scrubbing by hand and hosing with cold water; hot water has often not been available, and there is in any event probably some truth in the belief that fish slime is more difficult to remove with hot water than with cold. Cleaning agents are now available in bewildering variety, and many that are designed for a particular operation are of little value when used for any other purpose.

Soaps And Detergents. In today's time, everyone wants cleanliness around them, the substances like soaps and detergents bring the cleanliness, so today we are going to talk about soap and detergents briefly. Soap - Soap is the sodium or potassium salts of organic fatty acids with the high molecular weight. Soap is a household product which is mainly used in washing, bathing, and some other types of householding.
In the action of saponification, by heating the vegetable oil or aqueous solution of fat and caustic soda or caustic potash, the soap is produced by the chemical reaction, and the glycerol gets free. Soap is an organic mixture generates foamy froth in the water.
Its aqueous solution is alkaline which gives the blue color to red Litmus. Soaps are fatty salts of fatty acids. Such fatty acids can contain 6 to 22 carbon atoms. Generally, soap is not prepared from fatty acids.
Glycerides of fatty acids are found in the form of oil and fat. Due to these glycerides, most of the soap in the world is prepared with bacterial decomposition with sophisticated soda. Glycerin is obtained as a substance in the formation of soap which is a very useful substance. This company has imported soaps and market them here; Although North West Soap Company was the first company to plant a factory here in In a key part of the soap's success, Jamshedji Tata bought OK coconut oil mills at Kochi in Kerala in and established the country's first indigenous soap manufacturing unit.
Its name was changed to Tata Oil Mills Company, and its first branded soap market began to appear from the beginning of Raw Material for Soap - Oil, and fats are used in making large amounts of soap.
Rosin is also used in addition to these oils and fats. Most of the soaps are not made with one oil, although there are some oils that can make soap. Several oils and fats are used for manufacturing good quality soaps. Different types of soaps are made for different use.
Soap should be cheap for washing. But bath soaps can be expensive. The color of soap depends on the color of oil itself. Cleaning of oil and color for white soap is absolutely essential. The cleaning of the oil is done by heating a solution of some sodium hydroxide in the oil.
Sodium salts are made of rosin acid in soap. To make soap soft or flavoring and adhesive, a little ammonia or tri-ethanolamine are used. In the soap used for shavings, the above mentioned Chemical materials are required to be used. Making of Soap - To make soap, mix oil or fats with a solution of caustic soda and boil them in large pots or kettle. Size of the kettle can vary. Generally, the vertical cylinders of 10 to tonnes of hydration are made of soft steel. They are heated from the steam wound.
There are two sequences of pure soap: In a sequence, oil and fat are dissolved in water, resulting in glycerin, and fatty acids. Distillation can be a refinement of fatty acids. In the second order, the fatty acids tend to be depressed by the alkalis.
Use soda ash for potassium soap and potash base for soft soap. Methods of mixing and heating oil and alkali in the pan can vary in different factories.
Put oil in a pan somewhere and heat it and add soda solution to it. They take oil from somewhere and on the other hand soda solution is brought and is warmed.
Soap on the upper floor and the aqueous solution separates at the bottom. Put the concentration of alkali in soap 8 to 12 percent and then heat it for three hours. This completes the Soapization. If the color of soap is to be lightened, then put a little Sodium Hydrosulfite. Thus, the preparation of soap can take 5 to 10 days.
If the garment-washing soap is to be made, then add a little sodium silicate in it, frosting it, cutting it into the ticks and stamp on it. If you want to make a bath soap, then cut dry soap and grind it with essential color and aromatic stuff, then press it in the press and make the bar and cut it small by stamping it.
Soap doesn't work properly with hard water, and this is the biggest drawback of soap. Detergent - Detergent is a chemical liquid or powder which used to clean things.
Basically, detergent is the mixture of surfactants with the cleaning properties in the liquid form. Detergent is usually Alkylbenzene sulfonates, a compound which is similar to the soap but more soluble in hard water because the polar sulfonate of detergent is less than the polar carboxylate of soap bind to calcium and other ions which are found in the hard water.
The properties of detergent and soap are almost the same although detergent is more soluble, and because of this detergent gives good cleaning result in hard water too.
Anionic detergents - Anionic detergents are Alkylbenzene sulfonates. In Anionic detergents, the alkylbenzene is lipophilic, and the sulfonate is hydrophilic. According to one report, around 6 billion kilograms Anionic detergents are being produced per year for the domestic market. Cationic detergents - Cationic detergents are nearly the same as the Anionic detergents. The main difference between Anionic detergents and Cationic detergents is that the cationic surfactants have quaternary ammonium as the polar end.
Non-ionic Detergents and Zwitterionic Detergents - Uncharged, hydrophilic head groups are the characteristics of Non-ionic Detergents which is generally based on polyoxyethylene or a glycoside. Without altering the native charge of the protein molecules, Zwitterionic detergent protects the native state of proteins. It is used for isoelectric focusing and 2D electrophoresis. These detergents are known as sulfobetaines too. Germany was the first ever country to produce synthetic detergent.
Cleaning - The major application of detergents is household cleaning including dish Washing and washing laundry. Due to the supreme cleaning, the demand for detergent gets always high in the domestic market. Fuel additives - The components of carburetors and fuel injector of an Otto engine get benefited from detergents in the fuels to prevent fouling. Biological reagent - Reagent grade detergent is used for the isolation and purification of integral membrane proteins which is found in biological cells.

The first soaps were manufactured in ancient times through a variety of methods, most commonly by boiling fats and ashes. Archeologists excavating sites in ancient Babylon have found evidence indicating that such soaps were used as far back as B. By the second century A. In Europe, the use of soap declined during the Middle Ages.

The arrangements for cleaning equipment that comes in contact with products are an essential part of a food processing plant. It must be kept in mind that food manufacturers are always obliged to maintain high hygienic standards; this applies both to the equipment and, naturally, to the staff involved in production. This obligation can be considered under three headings:. Good, wholesome, clean products that keep well and are free from health hazards are obviously good for trade; customers will buy the same product again. However, if a product is contaminated, does not keep well or is the subject of complaints to the authorities, the reverse is true, and the resulting publicity is very damaging.SEE VIDEO BY TOPIC: SpecTank Demo
Healthy Cleaning This section is intended to be a valuable information resource about cleaning products for consumers, educators, students, media, government officials, businesses and others. Water, the liquid commonly used for cleaning, has a property called surface tension. In the body of the water, each molecule is surrounded and attracted by other water molecules. However, at the surface, those molecules are surrounded by other water molecules only on the water side. A tension is created as the water molecules at the surface are pulled into the body of the water. This tension causes water to bead up on surfaces glass, fabric , which slows wetting of the surface and inhibits the cleaning process. You can see surface tension at work by placing a drop of water onto a counter top. The drop will hold its shape and will not spread. In the cleaning process, surface tension must be reduced so water can spread and wet surfaces.
