Code and Title of the Paper: F01FS Food Science Code and Title of the Module: F01FS64 Spices and Condiments Active Principles Name of the Content writer: Dr. M. Amirthaveni Spices and Condiments –active principles Introduction Food substances, which enhance flavour, are known as spices. Spices are usually dried roots, barks; seeds used whole or crushed, powered and are aromatic. With its flavor and fragrance they give food a glorious touch. Usually spices are an ingredient used to season a dish in the meal during its preparation and condiments are for using at the table to enhance the dish as each individual's tastes prefer. What Is A Condiment? A condiment is generally something “extra” that is added to a food for “flavor” or taste stimulation or even for its preservative properties (like salt and vinegar). In other words, condiments are used for the taste “satisfaction” that it might provide and not for any nutritional value. Is a condiment also a food? Generally not. A substance that is eaten is either a natural part of the human dietary or it is a nonfood item that is used for some reasons other than nutritive ones. Condiments have little or no nutritional value. A true food may be eaten in such quantities that it can be a complete meal by itself. You can eat all you desire of a natural food, to repletion and satisfaction, and suffer no harmful effects. Of course, you can over eat any food, natural or otherwise, but generally speaking, you can certainly eat several mouthfuls of a natural food quite safely. Significance of spices and condiments Spices and condiments applies to such natural plant or vegetable products and mixtures thereof, used in whole or ground form, mainly for imparting flavor, aroma and piquancy to foods and also for seasoning of foods beverages like soups. The Code and Title of the Paper: F01FS Food Science Code and Title of the Module: F01FS64 Spices and Condiments Active Principles Name of the Content writer: Dr. M. Amirthaveni great mystery and beauty of spices is their use, blending and ability to change and enhance the character of food. Spices and condiments have a special significance in various ways in human life because of its specific flavours, taste, and aroma. Most of the spices and herbs have active principles in them and development of these through pharmacological and preclinical and clinical screening would mean expansion of considerable opportunities for successful commercialization of the product. Spices can be used to create these health promoting products. The active components in the spices phthalides, polyacetylenes, phenolic acids, flavanoids, coumarines, triterpenoids, serols and monoterpenes are powerful tools for promoting physical and emotional wellness.  Spices add flavour, colour to food and make the food palatable.  It stimulates salivation and acid secretion of digestive enzymes like amylase.  It has anti inflammatory, antibacterial and antioxidant properties. It reduces cholesterol levels useful in preventing heart diseases. Production of Spices Spices today, command the same respect as in earlier ages. Generally spices like chili, ginger, garlic and onion are grown in Maharashtra and like cardamom, cinnamon, clove, black pepper are grown in south India on large scale. Chillis is grown throughout India in over 9 lakh hectares of land. Andhra Pradesh and Karnataka are leading states in production. Rajasthan is the largest producer of coriander whereas Kerala, Meghalaya, Orissa and West Bengal form over 60%of the country’s production. Gujarat and Madhya Pradesh share the hours in garlic production. Kerala is considered as the land of spice crop, the plantation is concentrated in Idukki, Wayanad, and Kannur districts. Code and Title of the Paper: F01FS Food Science Code and Title of the Module: F01FS64 Spices and Condiments Active Principles Name of the Content writer: Dr. M. Amirthaveni Active Principles in Spices and Condiments Spice active principles are reported to have anti-diabetic, anti- hypercholesterolemic, antilithogenic, anti-inflammatory, anti-microbial and anti-cancer properties. Spices and their active principles inhibit 5-lipoxygenase and also formation of leukotriene C4. Modulatory effect of spice active principles viz., eugenol, capsaicin, piperine, quercetin, curcumin, cinnamaldehyde and allyl sulphide on in vitro human platelet aggregation has also been reported. spice active principles inhibit platelet aggregation induced by different agonists, namely ADP (50microM), collagen (500microg/ml), arachidonic acid (AA) (1.0mM) and calcium ionophore A-23187 (20microM). Spice active principles showed preferential inhibition of arachidonic acid- induced platelet aggregation compared to other agonists. Among the spice active principles tested, eugenol and capsaicin are found to be most potent inhibitors of AA- induced platelet aggregation with IC50 values of 0.5 and 14.6microM, respectively. The order of potency of spice principles in inhibiting AA-induced platelet aggregation is eugenol>capsaicin>curcumin>cinnamaldehyde>piperine>allyl sulphide>quercetin. Eugenol is found to be 29-fold more potent than aspirin in inhibiting AA-induced human platelet aggregation. Eugenol and capsaicin inhibited thromboxane B2 (TXB2) formation in platelets in a dose-dependent manner challenged with AA apparently by the inhibition of the cyclooxygenase (COX-1). Eugenol-mediated inhibition of platelet aggregation is further confirmed by dose-dependent decrease in malondialdehyde (MDA) in platelets. Further, eugenol and capsaicin inhibited platelet aggregation induced by agonists- collagen, ADP and calcium ionophore but to a lesser degree compared to AA. These results clearly suggest that spice principles have beneficial effects in modulating human platelet aggregation. Types of spices and their use  All spice or Pimento It is a small berry, size of the pea, dried to a dark brown colour.

Curcumin, the yellow coloring matter of turmeric (haldi) has likewise a powerful antibacterial action and asafetida destroys coliforms and anaerobes in the cecum. The curcumin of turmeric is an antioxidant that can prevent the food from oxidative spoilage, a very common occurrence if an oil is present. Medicinal value Protective factors in turmeric help in detoxifying harmful drugs or chemicals that are converted to toxic metabolites. Turmeric also helps in increasing the mucin content of gastric juice and reduces irritation in stomach. It is also used to relieve sore throat, cough, cold and against flatulence. Studies carried out at National Institute of Nutrition Hyderabad suggest that turmeric can be a potent anticancer agent. Turmeric isolated from turmeric showed a potent antioxidant and anticarcinogenic properties. The active principle of turmeric, curcumin is known for its inhibitory action on bacteria and arrests the growth of fungi. Turmeric and curcumin have been reported to reduce the levels of cholesterol in experimental animals given high cholesterol containing diet. Turmeric volatile oil markedly reduced the secretion of hydrochloric acid in the stomach. Curcumin (from turmeric) lowered the levels of blood and liver cholesterol and had shown indication of being of value in the management of diabetes.  Vanilla Vanilla beans are being cultivated in Kerala.
