कृत्रिम ट्रांसफैट कैसे तैयार किये जाते हैं ?

माजरीन कृत्रिम मख्खन को आप कह सकते हैं यह पशु या वनस्पति से बना मख्खन जैसा खाद्य पदार्थ है। और कृत्रिम ट्रांस फेट के एक उदाहरण के रूप में आप इसे ले सकते हैं। 


कृत्रिम ट्रांसफैट कैसे तैयार किये जाते हैं ?


(खाद्य )तेलों (liquid oils )की भंडारण अवधि बढ़ाने के लिए इन से तैयार खाद्यों का स्वाद बढ़ाने के लिए    इन्हें ठोस चिकनाई (solid fats ) में तबदील कर दिया जाता है। इस प्रक्रिया को तेलों का हाड्रोजनीकरण कहा जाता है। ऐसा करने से तेलों की ठोस रूप में भंडारण अवधि बढ़ जाती है। इनसे तैयार खाद्य जल्दी सड़ते नहीं हैं। सुस्वादु भी बने रहते हैं। 

इन्हें खाद्य  संरक्षी भी कहा जाता है। अमरीकी खाद्य एवं दवा निगरानी संस्था FDA ने इन्हें खाद्य श्रृंखला से बे -दखल करने की मुहिम  छेड़ दी है। इनकी कोई सुरक्षित सीमा (न्यूनतम सुरक्षित समझे जानी वाली मात्रा )नहीं है। फिलवक्त  अमरीकी समाज औसतन एक दिन में एक ग्राम ट्रांस फेट का सेवन कर रहा है। संस्था के अनुसार इस मात्रा को और भी कम कर देने से हर साल अमरीका भर में २० ,००० दिल के दौरों और परिहृदय धमनी रोग (CAD -coronary artery diseases )के ७ ,००० नए मामलों से देश को बचाये रखा जा सकता है। 

CSPI अमरीकी संस्था सेंटर फॉर साइंस इन पब्लिक इंटेरेस्ट के अनुसार अभी भी ट्रासंफेट अमरीकी खुराक में अपनी जगह बनाये हुए हैं। भले कई खादय निगमों ने पहल करके इसकी मात्रा को कम ज़रूर  किया है।

Put down that doughnut: FDA takes on 

trans fats




(CNN) -- So long, margarine: Artificial trans fat in foods may eventually become a thing of the past.

The Food and Drug Administration on Thursday took a first step toward potentially eliminating most 

trans fat from the food supply, saying it has made a preliminary determination that a major source of 

trans fats -- partially hydrogenated oils -- is no longer "generally recognized as safe."

If the preliminary determination is finalized, according to the FDA, then partially hydrogenated oils will 

become food additives that could not be used in food without approval. Foods with unapproved 

additives cannot legally be sold.

Trans fat can be found in processed foods including desserts, microwave popcorn products, frozen pizza, 

margarine and coffee creamer, and has been linked to an increased risk of heart disease.


Partially hydrogenated oil is formed when hydrogen is added to liquid oils to make solid fats, like 

shortening and margarine. It increases the shelf life and the flavor of foods. Partially hydrogenated 

vegetable oil, or shortening, was used in American kitchens as early as 1911.


However, in recent years many food manufacturers have taken steps to limit or eliminate trans fat from 

their products.

McDonald's, for instance, stopped cooking its french fries in trans fat more than a decade ago. The 

company's website says all its fried menu items are free of trans fat.

New York City in 2007 adopted a regulation banning partially hydrogenated vegetable oils and spreads 

in restaurants.

Mayor Michael Bloomberg said Thursday that he was encouraged by the FDA's move.


"The groundbreaking public health policies we have adopted here in New York City have become a 

model for the nation for one reason: They've worked. Today, New Yorkers' life expectancy is far higher 

than the national average, and we've achieved dramatic reductions in disease, including heart disease. 

The FDA deserves great credit for taking this step, which will help Americans live longer, healthier 

lives," Bloomberg said.


Trans fat intake among American consumers decreased from 4.6 grams per day in 2003 to about a 

gram a day in 2012, according to the FDA.


However, "current intake remains a significant public health concern," FDA Commissioner Margaret 

Hamburg said in a written statement.


There is no safe level of consumption of trans fat, Hamburg said. It has been shown to raise the "bad," 

or LDL, cholesterol.

"Through our efforts at product reformulation and the development of suitable alternatives, trans fats 

that are not naturally occurring have been drastically reduced in the food supply," the Grocery 

Manufacturers Association, which represents more than 300 food, beverage and consumer product 

companies, said in a prepared statement.

"Since 2005, food manufacturers have voluntarily lowered the amounts of trans fats in their food 

products by over 73%."

Other countries are also working to reduce trans fat in the food supply. Policies in Brazil, Costa Rica, 

Denmark, the Netherlands, South Korea and the United States have proved effective over the past two 

decades, the World Health Organization said in April. The WHO has called for eliminating trans fat from 

the global food supply.


The FDA has opened a 60-day comment period on the determination "to collect additional data and to 

gain input on the time potentially needed for food manufacturers to reformulate products that currently 

contain artificial trans fat should this determination be finalized," the agency said.


There are two phases to the process, FDA officials said Thursday. The agency will evaluate the 

comments and evidence received during the comment period.

"If we finalize our conclusion, then we are inviting comments from industry on what would be an 

appropriate phaseout," said Michael Taylor, the agency's deputy commissioner for foods.

"The timeline would be based on the comments we get. Given the public health impact, we want to move 

as quickly as we can."

The National Restaurant Association noted in a statement the industry's "tremendous strides" in 

reducing or eliminating trans fats.

"We plan to discuss the impact of this proposal on the industry and submit comments, and we will 

continue to work with our members and the manufacturing supply chain to address any new federal 

standards that may arise out of this process," said Joan McGlockton, the association's vice president of 

industry affairs and food policy.

Hamburg called Thursday's move "an important step toward protecting more Americans from the 

potential dangers of trans fat."

The American Heart Association, the American Medical Association and the Center for Science in the 

Public Interest were among those praising the move.

"The scientific evidence is clear -- eating food with trans fat increases production of 'bad' cholesterol, 

which is a risk factor for heart disease," the AHA said.

So what should consumers do in the meantime? Choose products that have the lowest combined 

amount of saturated fat, cholesterol and trans fat, the FDA said.

Under current regulations, companies can claim their food has 0 grams of trans fat if the food contains 

less than 0.5 grams of trans fat per serving, according to Mical Honigfort, a consumer safety officer at 

the FDA. But if partially hydrogenated oil is listed in the ingredients, there may still be a small amount of 

trans fat present.

Nancy Brown, the Heart Association's CEO, said she hopes the FDA goes a step further and revises 

labels for foods that are trans fat free.

The preliminary determination was based on "available scientific evidence and the findings of expert 

scientific panels," the FDA said.

The determination covers only partially hydrogenated oils, not trans fat that naturally occurs in some 


meat and dairy products. Trans fat is also present at very low levels in other edible oils, such as fully 

hydrogenated oils, where it is "unavoidably produced during the manufacturing process," according to 

the FDA.

Avoiding foods containing artificially produced trans fat could prevent 10,000 to 20,000 heart attacks 

and 3,000 to 7,000 coronary heart disease deaths each year, according to one study from the U.S. 



"Artificial trans fat is a uniquely powerful promoter of heart disease, and today's announcement will 

hasten its eventual disappearance from the food supply," said Michael Jacobson, the Center for 

Science in the Public Interest's executive director. "Not only is artificial trans fat not safe, it's not 

remotely necessary. Many companies, large and small, have switched to healthier oils over the past 

decade. I hope that those restaurants and food manufacturers that still use this harmful ingredient see 

the writing on the wall and promptly replace it."
