HERE COMES THE LATEST FAT BUSTER-GEAR UP YOUR PALATE!

The Indian traditional culinary preparation, "The Curry" has been ridiculed so often by those who cannot tolerate the spices contained in the product that new generation products, modified curries, are being made in many modern day homes and restaurants, which are practically bland devoid of important spices like Chilli, Turmeric, Coriander, Asafoetida etc. Is it not a tragedy that the modern day generation of youngsters born to Indian parents shy away from such traditional preparations and flock to junk foods like burgers, hot dogs, sandwiches, pizza etc? It has been known for quite some time that many spices and herbs are treasure houses of many proven health protecting phytochemicals and older generation Indians and Chinese to some extent recognized the precious value of these ingredients hundreds of years ago, making their regular consumption as a part of daily diet. Chilli is a spice studiously avoided by the western population, possibly because of the "heat" it generates on the palate not generally tolerated by them. But is it not a fact that Mexican foods reputed for high pungency are popular in many parts of the world including the US and Europe and restaurant chains like Chipotle, Taco Bell etc are omnipotent by their presence every where?  Recent assertion by a group of scientists that Chilli can be beneficial in reducing body weight  through busting the belly fat and suppressing hunger significantly is bound to bring more focus on this simple spice in coming years.  

A research group in Netherlands has  recently come out with its findings on the effect of Chilli on weight reduction According to them this hot spice can work in three different ways, the ultimate effect being a net lose of body weight. They are capable of burning fat, suppress hunger pangs and boost overall calorie-burning rates in the body. It appears that the chemical capsaicin in Chilli responsible for its heat, triggers rapid secretion of the hormone adrenalin  from the glands which in turn stimulates the brain to send messages to burn fat cells selectively. Interestingly such a fat burning spree is confined to that present around the belly which was found to be burned most rapidly. Midriff fat is considered the most dangerous because it significantly increases the risk of heart disease in human beings.

Scientific evidence to support the above claims may not be very substantial but what ever data have been generated do show that there is some thing significant about the effect of Capsaicin on humans that deserves to be investigated further. For example this Chilli constituent has been found to be suppressing action of Ghrelin, a hormone known to be involved in promoting hunger which indirectly goes to show that Chilli consumption can suppress appetite. Studies with human beings who consumed Chillies before a meal showed significantly lesser appetite than normal subjects. Similarly Chilli consumption considerably rev up thermogenesis in the body and since there was no perceptible increase in metabolic activity, it is assumed that fat is being burned in preference to carbohydrates. Both these deductions may be valid and appetite suppression combined with preferential fat burning can accomplish weight reduction over a continued period of Chilli consumption. It is however not clear whether other analogs of Capsaicin like Dihydrocapsaicin, Nordihydrocapsaicin, Homocapsaicin and Homodihydrocapsaicin will also be effective in fighting obesity. The synthetic version Nonivamide is also another candidate worth testing.

Capsaicin is suggested as a supplement for aiding digestion as it stimulates production of digestive juices in the stomach besides fighting undesirable bacteria with pathogenic potential. Capsaicin is also implicated in preventing heart disease as it appears to retard blood clotting, reduce blood cholesterol and prevent hardening of arteries. But its fat busting properties are only reported now and it is theorized with some evidence that Capsaicin stimulates certain proteins that is known to break down fat while inhibiting action of other proteins that synthesize fat in the body. An imponderable factor in using Capsaicin for weight reduction programs is whether the lost weight will return once the consumption is stopped and this needs to be explored before it can become a standard diet supplement for people intending to lose weight..

Even assuming that there is adequate scientific support to the above claim, the million dollar question is how can people intolerant to Chilli heat can be made to consume the same without creating any trauma? Response to Chilli ingestion varies from person to person with some people seriously affected by even small levels of Chilli in the food. In some consumers it causes diarrhea while in others it creates intense discomfort in the GI tract. Probably technologies like encapsulation and micro encapsulation can by pass the palate reducing the intense pungency in the mouth. Organic chemists may even come out with modified Capsaicin molecules which can exert same effect as natural Capsaicin on the metabolic dynamics of human body. Another route to is to train people slowly in consuming Chilli over a period of time as there are hundreds of varieties of Chilli with varying "Scoville" score, reflecting the heat generating capacity on the tongue. Possibly those varieties with lower heat value can be made popular in the first instant among Chilli "haters" to get them acquainted with the heat properties and it is a question of time before they can be hooked on to regular Chillies.

SPICE OLEORESINS-FOOD OR NUTRACEUTICAL?


India is universally recognized as the "spice country" because of the occurrence of a wide variety of spices, condiments and herbs which are used in culinary preparations by population across the country. However the major focus for the spice extractive industry has been on Chilli, Black pepper, Ginger, Turmeric and Cardamom. While Cardamom oil is a much valued flavor material for hundreds of food preparations and beverages, whole spice extractives, more commonly referred to as oleoresins, have become important ingredients for the food industry for incorporation in many processed food products. Oleoresins with standard and reliable "active constituent" concentration have several advantages compared to use of whole spices, hence the preference by the industry.

Oleoresin technology remained an exclusive possession of some multinational companies covered by patent protection till the monopoly was broken by India through the efforts of CFTRI, Mysore. Attempts to stifle this indigenous development were made by changing the product specifications to restrict solvent residue levels and banning some of the solvents found to be efficient in getting increased yields. It is a tribute to Indian scientists that they were able to overcome these hurdles and enabled Indian spice industry to attain dominance in the international market. With an export of 6850 tons of oleoresins last year India accounted for more than 70% of global supply in this category. To day India has the awesome capability to extract about 42 different spices to meet every demand from the industry.

Against the above background comes the news that India has imported 400-500 tons of Chilli oleoresins from China which is not known to be a major producer of spice extractives. Probably the reputation Chinese have in dumping industrial products at ridiculously low cost must have lured some users to import from China and the lax import procedures also must have helped in clearing the imports without necessary safety assessment, especially with respect to solvent residue in the product. Whether China has developed its own technology or copied from others or the product really conforms to international standards is a mute question but India must be ready to face the "Dragon" in the coming years through constant technology upgrade for which adequate R & D investment is inevitable.

The above news may be alarming because oleoresins are increasingly becoming important for pharmaceutical industry with many applications being considered effective in treating several human afflictions. Curcuminoids in Turmeric, Piperine in Black pepper and Capsaicin in Red Chilli, are the three major materials of commercial importance. These phytochemicals have been proved to be of excellent nutraceutical value capable of preempting or curing most of the disease conditions that human race faces to day. Recent revelation that curcumin and piperine are effective in killing stem cells that differentiate into breast cancer cells, is of prime importance to the medical community. Similarly capsaicin has been proven to be effective in treating prostate cancer besides an excellent resource to treat inflammation, pain relief, fight sinus infection, irritable bowel syndrome, burning body fat, reducing cholesterol and triglycerides, dissolving clot inducing fibrin, preventing platelet aggregation and protecting the heart, relief from arthritis, psoriasis and diabetic neuropathy.

If these claims are true a time may come when oleoresins may not be available to the food industry with demand from the pharmaceutical industry outstripping that from the former. Probably cultivation of crops like Chilli, B. Pepper and Turmeric may expand several fold as commercial non-food crops! Such developments may also spur synthetic organic chemists to look for synthetic routes to make these much valued substances. Already synthetic capsaicin is available in the market and time may not be far off when synthetic versions of others start appearing. The present preference for natural sources for internal consumption is the only constraint that stands in the way of synthetic analogs dominating the market.
