Emulsifying Agents And Types Of Emulsifiers

Posted on by

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.

Adhd Symptoms And Magnesium Deficiency

Posted on by

Magnesium deficiency may bring about ADD and ADHDsymptoms. The reasons for this involve understanding what Magnesium is and how it works in our bodies.

Magnesium is a mineral. It is the 4th most abundant element in your body. ADHD studies have shown that Inadequacies in magnesium can bring on a host of problems and symptoms are among the symptoms that have been linked to nutritional Inadequacies of this mineral.

The majority of teen age children in this country have, according to Scientific studies performed by the Centers for Disease Control and Prevention and the Unites State Department of Agriculture, significant magnesium Inadequacies.

Magnesium is necessary for hundreds of chemical reactions in the body. Our muscle and nerve function depends on magnesium as do our skeletal system and our immune system. Magnesium is needed to maintain normal blood sugar levels and a normal blood pressure. Perhaps the most significant role that magnesium plays is in protein synthesis and energy metabolism.

Magnesium works with calcium to power the cells in our body but according to the 2006 National Health and Nutrition Examination Survey (NHANES) and published in the U.S. Department of Agriculture, What We Eat in America, 2006-2007 Report, most of our kids have magnesium Inadequacies. Many younger young kids and adults do as well but the statistics are most alarming for teens. Eighty-nine percent of boys and seventy percent of girls aged 14-18 have inadequate dietary intake of Magnesium.

Research Studies have found that magnesium can be used to improve a host of conditions including anxiety and depression. There is some scientific evidence that magnesium may be able to regulate neurotransmitter function. Deficiencies in magnesium, which can caused by excess perspiration or by decreased diet intake will worsen these conditions.

These Inadequacies may result in faulty neurotransmission as well as anxiety, depression, migraine headaches, mood disorders, hyperactivity and decreased concentration. Low magnesium has also been linked to sudden cardiac death, mitral valve prolapsed, diabetes and hypertension.

Several Research Studies have shown that supplementation with 80 mg to 200 mg of magnesium daily improves anxiety, depression and ADD and ADHD symptoms.

Most multivitamins have between 20mg to 50 mg of magnesium. This may be plenty of supplementation if you, or your children, are eating foods that are rich in magnesium such as green leafy vegetables, lot of whole grains, walnuts, cashews, and peanuts, beans, fish, pumpkin, bananas, avocados, raisins, milk products and tomato paste but is likely not enough if you are not and if this is the case then supplementation is required.

Magnesium is an essential nutritional element that may be deficient in the diet of most Americans. High schoolers in particular, are likely to have magnesium Inadequacies. Magnesium is lost through respiration and sweating and active people are more at risk for having borderline low magnesium levels than people who are sedentary. Eating foods high in magnesium or supplementing your diet with a magnesium vitamin is essential to avoid the poor health outcomes that result from low magnesium levels.

Check your multivitamin to insure that you and your children are getting enough magnesium. Those of us, who like hot chocolate and coffee, have yet another reason to drink more of these beverages. It turns out that cocoa and caffeine both contain a fair amount of magnesium. Some of the mood lifting effects of chocolate and coffee could be attributed to these magnesium levels.

The Attention Deficit Hyperactivity Disordercommunity has been quick to recommend fatty acid supplementation to improve the behavioral symptoms that bring on problems in people with Attention Deficit Disorder. The research community is only now learning that nutritional substances such as calcium, magnesium and zinc also play a role in moderating our mood and our behavior.

By supplementing our diets with magnesium we may avoid worsening the symptoms of ADHD and may, in the process not only improve our overall health but also diminish the incidence of developing conditions such as depression and anxiety that often accompany a diagnosis of ADHD.

Eleven Million in Sahel Face Severe Food Insecurity

Posted on by

A U.N. agency says 11 million people in Africas Sahel region still face severe food insecurity. At the same time, an emergency appeal for 113 million dollars has gone largely unmet.

De Capua report on Sahel food insecurity
The Food and Agriculture Organization says the Sahel has faced food insecurity crises in 2005, 2008 and again in 2012. Those crises, it says, have eroded the capacity of the poor to maintain or restore their livelihoods.

In Dakar, Patrick David, FAOs deputy coordinator for food security analysis for West Africa and the Sahel, said, There is still a lot of people in food insecurity. The people more and more find some difficulty to recover from the past crisis even if there is a good harvest because there have been pretty good harvests in 2012.

David said many people in the Sahel depend on a few cattle and a small piece of land for survival. So, its hard for them to stock up any reserve food or agricultural supplies in the event of drought, conflict or bad harvest.

While before it would take one or two years to recover, now its longer for those people to recover. Its difficult to restock cattle, for example. Its difficult for them to access agricultural credit to have good input[s] and to have fertilizer. And in some places in the Sahel, like in Burkina Faso and Niger, there [are] some dense populated area[s] where there is degradation of land and the loss of soil fertility. That means their agricultural
yield[s] are decreasing year by year, he said.

That compounds the problems they already face as the price for grains, such as sorghum, millet and maize, continues to rise.

David said, The poor and the very poor households, as soon as theyve exhausted their little harvest, totally depend [on] the market. So they have to buy the grain at higher and higher prices. So their purchasing power is decreasing every year.

Insecurity, such as the recent conflict in northern Mali, can also boost prices because agricultural products cannot get to market.

The FAO has appealed for $113 million for its programs in the Sahel. However, its only received less that $19.5 million so far.

The intervention of FAO strengthens the resilience of the affected households. But when the affected households cannot receive the good seeds and the good fertilizer or cannot recapitalize their livestock, they stay very vulnerable and its a problem for the next year. So we definitely need additional support for the farmers and agriculture in order to decrease the impact of the forthcoming crisis, he said.

Building resilience includes improving the storage, processing and transportation of goods as well as livestock food supplements, animal health campaigns and herd restocking. The Food and Agriculture Organization programs also include fixing irrigation systems.

The FAO said it would like these programs to be in place and making a difference during the next growing season which runs from October through April

Protect The Agriculture State Idaho From The Bad Effects Of Pollution Through Dumpster Rental

Posted on by

The contribution of agriculture towards GDP of the country is one percent but it still occupies place among the major sectors of the economy of the US. Idaho is the agriculture state and it is affected by the pollution generated from the industries. The waste that is transmitted from the industries is piped into streams and lakes and is contaminating water and affecting the agriculture sector in the state.

Idaho is an agriculture state and is a producer of nearly one third of potatoes grown in the US. The recent growth of industrialization is affecting the agriculture sector of the state. The agriculture land of the state is supplied water contaminated with the waste emitted from industries, the agricultural land is producing less than what it actually can.

The agriculture sector the main source of economy of the state can no longer yield the expected results if the same situation continues to exist. The waste generated by these industries is disturbing environmental balance of Idaho which is very important for proper growth of the crop. Immediate action should be taken to protect the environment from pollutants that are emitted from the industries and other projects that are carried in the state.

Government of Idaho has taken many steps in this regards. They focused at Ground Water Quality Protection, Surface Water Quality and BMP Evaluation, Idaho State Pesticide Management Plan, Smoke Management & Crop Residue Disposal. They run a special month namely Pollution Prevention month which encourages business organizations, communities, individuals, and schools to join in one of the activity that protects the environment of Idaho from the bad effects of pollution. some of these activates include Prevention, elimination, or minimizes the production of waste or pollutants at its source, Use non-toxic or less-toxic products, Conserves energy or water, Re-uses materials rather than throwing them away.

Number of industries participated in the activity and the state experienced significant reduction in the impact of pollution in that particular month. The importance of practicing these activities should be enlightened in the society. The residents of state should take initiative to participate in such activities but restricting these kinds of practices to a single month would yield no great results, it should be an ongoing process.

Environmental protection of the state is facing a great problem at this juncture. In spite of great benefits of these activities only few business organizations, individuals; industries come forward to share their responsibility in environmental protection. Most of them step back fearing that it is tough process. Not everybody in the state will be ready to sacrifice their comforts for the sake of protecting the environment.

Not a worry, a wonderful option is at your door step now; you can now put all these aspects into action without sacrificing any of your comforts. How? Dumpster rental Idaho is the one stop solution for all the problems. Minimization of waste production is always advisable. But it sometimes becomes inevitable, when you rent a dumpster in Idaho, the trash will be recycled in environmental friendly manner and the impact of trash generated will be less. Dumpster rental Idaho will recycle all the eligible trash and transfer the rest to the landfill so there is no chance for the dump to get disposed in the streams and lakes. Dumpster rental Idaho will help you to maintain the environmental balance and protect the water of state from being polluted there by helping in increase of agriculture production of the state.

The History And Agriculture Of The Wolfberry

Posted on by

Wolfberry is the name given to the Chinese and European variety of the Goji berry. It actually goes by many other names and has more than 100 species. The Lyceum Barbarum Wolfberry is the most popular species of this plant. It is the best tasting one and is used for making Goji juice and for medicinal uses in Asia and India.

The Wolfberry is a shrub that can grow up to 10 feet with trailing vines spreading to up to 20 feet. In China it is cultivated in large plantations for commercial use. These commercial farms use conventional chemical methods to grow the Wolfberry and protect it from insect damage. The largest growing area is the Ningxia Hui Autonomous Region, in Northern China. This is where they grow the Lyceum Barbarum Wolfberry. This species was originally taken from Tibet and the Himalayan region.

Other varieties of this plant can be found growing wild in various parts of the world including the UK. It is known as the Wolfberry and also has other names, like The Box Thorn Fruit and The Matrimony Vine Fruit. This plant grows wild in the cooler parts of Europe and Asia.

In Tibet and Inner Mongolia the Wolfberry is known as the Goji Berry. It is one of the protected medicinal plants in this area. Because of its use as a medicine plant the Wolfberry is grown organically there with no additional chemicals. The areas it grows in are labeled as “wild places” and are relatively untouched by urban development. An organization Co-op for the Goji farmers that ensures they get fair prices and help continue growing Wolfberry plants, was created in 1975. The Tanaduk Institute has also helped to protect the medicinal plants grown in this region. Several monasteries in India also grow medicinal plants including the Wolfberry. They are grown organically here and are sold on a limited basis.

The plants are quite easy to grow and can be started from seed. The seeds take around 7 days to germinate. The Wolfberry can also be cultivated from roots. It is resistant to drought and can withstand temperatures of -15 degrees Fahrenheit in winter and up to 100 degrees Fahrenheit in summer. The Wolfberry prefers light soil for optimum growth but will grow in any soil. Ideally the plant prefers full sunlight but will also grow in partial shade.

You can cultivate The Wolfberry in containers. If you do this, you need to hand pollinate the Wolfberry flowers, to get the fruit. The fruits are quite vulnerable to insect damage so you should take steps to protect the plants when they are producing fruit. The Wolfberry plants begin to bear fruit from the age of 1 year and will produce heavy crops when they are between 4 and 5 years old. They start to bloom in early summer and develop fruit in late summer. The Wolfberry will continue to bear fruit until the first severe frost. The best way to get the maximum health benefits from this plant is to try to grow it naturally without chemicals, herbicides or insecticides.
