Sesame oil (also known as gingelly oil or til oil) is an edible vegetable oil derived from sesame seeds. Besides being used as a cooking oil in South India, it is often used as a flavor enhancer in Chinese, Japanese, Korean, and to a lesser extent Southeast Asian cuisine.The oil from the nutrient rich seed is popular in alternative medicine - from traditional massages and treatments to modern day fads. The traditional Indian medical practice of Ayurveda uses sesame oil to pacify stress related symptoms. Ongoing research also indicates that the rich presence of antioxidants and polyunsaturated fats in sesame oil could help control blood pressure.The oil is popular in Asia and is also one of the earliest known crop-based oils, but world-wide mass modern production continues to be limited even today due to the inefficient manual harvesting process required to extract the oil.
Coconut oil is an edible oil that has been consumed in tropical places for thousands of years. Studies done on native diets high in coconut oil consumption show that these populations are generally in good health, and don’t suffer as much from many of the modern diseases of western nations where coconut oil is seldom consumed anymore.Coconut oil was once prevalent in western countries like the United States. With a long shelf life and a melting point of 76 degrees, coconut oil was a favorite in the baking industry. But a negative campaign against saturated fats in general, and coconut oil in particular, led to most food manufacturers abandoning coconut oil in recent years in favor of hydrogenated polyunsaturated oils that come from the main cash crops in the US, particularly soy.
Mustard is a well-known oil seed and an annual crop. It has round stem with long inter-modes, simple, alternate and very soft yellowish green leaves. The fruit is a pod containing seeds. Dry mustard seeds are small, round and darkish-brown or grayish-brown in color. They have no smell, but when pounded and moistured with water, they emit a peculiar strong smell.Mustard oil is of vegetable origin and is obtained from seeds of the black and white (Sinapis alba) mustard plants. In the crude state, black mustard oil (Brassica nigra, light color) has a spicy odor and a strong taste. When refined it is neutral in odor and taste.
