Emulsifying agents are soluble in fat and water to allow uniform dispersion of fat in water. Emulsifying agents are also called emulsifiers and present in the food like butter, mayonnaise and salad dressing. These have one hydrophilic and one lipophilic part. These agents surrounds the oil droplets in water and reduces the tension between the two liquids thus impart stability.

Classification of Emulsifiers
These can be classified on the basis of chemical structure and mechanism of action. Under chemical structure category are synthetic, natural, auxiliary agents and finely dispersed solids. In the category of mechanism of action comes the monomolecular, multimolecular and solid particle films.

Natural emulsifying agents are derived from plant and animal tissues and mostly in the form of hydrated lypophilic colloids. These emulsifiers make the protective sheath around the droplets, give droplets a charge so that they repel each other and swell to step-up the viscosity of the liquid.

Natural ones are derived from vegetables, animals, semi synthetic and synthetic agents. Although natural agents are inexpensive, safe and non toxic but these are slow in action. So large quantity of emulsifier is required for proper action. Also the natural emulsifiers need preservatives as these are subjected to microbial growth.

The animal derivatives are stronger than the plant ones. The best example of this is lecithin and cholesterol. Some people are allergic to these so must be consumed after knowing the derivatives.

Both semi-synthetic and synthetic emulsifying agents are strong and require no preservative as these are not prone to microbial growth.

Applications of Emulsifying Agents
Emulsifiers are used in many types of food for stability and to reduce tension. Like vinaigrette if prepared only with oil and vinegar leads to unstable emulsion. To stabilize mayonnaise egg yolk lecithin is used as emulsifiers. Both natural as well as synthetic emulsifiers are used in food industry. Egg, soybean, rapeseed oil and palm oil are the common natural agents. Dairy products like cheese and ice creams use the emulsifying agents to improve the texture. Also the crystallization of candies is improved by them. Jarred peanut-butter and sauces are given more life with the use of correct emulsifier.

It is extensively used in pharmaceutical industry to make medicines more good to taste and easy to take. In pharmaceutical oil and water emulsions are basically used. These are also used in other industries like agriculture, paints and inks. Fertilizers and pesticides are given more stability with these.

Harmful Effects
Although the one used in food are completely safe and more over natural ones are safer than synthetic. But in some cosmetics certain harmful emulsifiers like polyethylene glycol (PEG) compounds, have been found that are carcinogenic. Also the emulsifying agents in body care products causes mild or severe allergies of skin.

The arrival of tropical storms, like this year’s Tropical Storm Barry, coincides closely with the typical date for onset of Florida’s so called ‘rainy season’ that generally runs from late May to October. Although Florida fishermen experienced a record ‘dry season’ this year, the occurrence of drought during the cooler winter and spring months was hardly unusual. Bass fishing in [tag-ice]Lake Okeechobee suffered as water levels reached all-time lows, exposing large areas of lake bottom and leaving many boat ramps high and dry.

There has been a silver lining to the drought for the Florida strain of largemouth bass living in Lake O, as some locals call it. The Army Corps of Engineers began a project last year to scrape decades of accumulated “muck” off the exposed lake bed. Phosphorus and nitrogen runoff from fertilizers used on farms, golf courses and lawns has been building up in Okeechobee ever since the natural flow of water out of the lake was reversed early in the 20th century to help retain a supply in Lake O for agriculture and drinking water. These chemicals generate unnatural spread of certain plants and algae which overgrow then die off and coat the bottom this the toxic “muck.”

The bass fishing in Okeechobee should benefit both from Barry’s rain and the new sections of the natural sandy bottom of Lake O revealed after the dredging. As the water levels rise, natural grasses will reclaim the cleaned areas, dissolved oxygen levels should increase in the absence of the artificial plant blooms, and much new spawning habitat will open to the monster bass Lake Okeechobee is famous for.

Bass fishermen headed to Lake O should expect to find the bass in heavy grass cover. Try the new Okeechobee Rig, a lure developed specifically for fishermen flipping for bass in dense brush or grass cover. You’ll need to be casting strong braid or mono to effectively haul out hooked bass – at least 20lb test, but 30-60lb braid is commonly used on the tournament trail. I set up with Power Pro rigged with a Seaguar Flourocarbon leader.

EDTA is a well known chelating agent used in food and Pharmaceutical industries for preparing various formulations. It actively binds with several toxic metals like cobalt, lead, mercury that makes them inactive-nontoxic to dissolve in blood and excrete out from the body organs. Due to this property they are widely used in agriculture, horticulture, food and pharmaceuticals.
Various combination of EDTA with several minerals has increased their industrial usages. The active formation of Disodium with EDTA is used in molecular biology as an inhibiting agent. The mineral formations of EDTA contains different molecular weight and PH values applicable differently. Due to their chemical actions on human body, these EDTA products are applied widely in producing high quality crop in bulk quantity. Even minerals enrich EDTA also used in preparing human food as well for animal feeds.
Applications of Various EDTA Products
EDTA Tetrasodium is having the best cleansing property used in preparing cleansing materials, also used in agriculture to fulfill the Tetrasodium requirement of soil for better quality plantations.
EDTA Zinc is used in manufacturing zinc enrich fertilizer that is widely demanded in agriculture industry now-a-days. EDTA Zinc fulfills the requirement of Zinc to the soil and helps the crop growing well.
EDTA Copper provides the nutritional element of copper for better agriculture production. This creates a great combination while mixing with other EDTA products in fertilizer and increases the fertility of the land. Every farmer should know the content ingredient of the fertilizer while purchasing them.
The high grade EDTA Manganese is used in several fertilizers to provide the manganese to the soil. The pure EDTA manganese are pinkish color powder with minimum metal content increase the manganese level of the soil that is required for better growth of plantation and crop and ultimately gives bulk agriculture production.

The role of EDTA Magnesium is quite important in fertilizer industry as it promotes the photosynthesis process in the plants, also increase the absorption value of irons in them. It stimulates the enzymes in plants for fast processing. EDTA Magnesium is one of the most important and widely demanded ingredients in agriculture industry.
EDTA Calcium is another chelating agent effectively works on metal and makes them non-toxic. The chelated calcium also used as fertilizer to increase nitrogen metabolism and gives hard structure to the plants. It also applies in healing process in pharmaceuticals and agriculture.

EDTA Ferric has also a contributing to enrich the soil with ferric, when used in fertilizer. It is good water soluble micronutrients that provides better nourishments to the plants and grow them well. Dried Ferrous Sulphate is used to stimulate the growth in animal body as well having good importance value in agriculture fertilizer to increase the crop production.
Shivam Agro Industries is a leading manufacturer of EDTA (Ethylene Diamine Tetra Acetic Acid) products including EDTA Acid, EDTA Disodium, EDTA Tetrasodium, EDTA Zinc, EDTA Copper, EDTA Manganese, EDTA Magnesium, EDTA Calcium, EDTA Ferric and Dried Ferrous Sulphate at the most affordable rates.
