Culinary Uses
Peanut oil is one of the widely used vegetable oils of the world. A pretty common cooking oil in Asian countries, this oil is also used in western countries. It also has numerous  applications in Asian cooking. In west, it is widely used for frying foods, particularly french fries, turkey and chicken. This edible oil is often used in salad dressings, marinades, and baked goods.

It is the most widely used cooking oil in the South Indian state of Andhra Pradesh. It is one of the healthiest cooking oils for day to day needs and a tablespoon (approximately 15 grams) of peanut oil has just under 120 calories. In China, the peanut oil used is less refined, retaining a little bit more of the protein of the peanut and producing a stronger peanut flavor.

Uses of Palm Oil
As much as 90% of the palm oil produced finds its way into food products, while remaining 10% is consumed by various industries. It is widely used preparing margarine, shortening, and vegetable cooking oil. In many parts of the world, it is still consumed in its unrefined state to obtain a distinctive colour and flavour. Palm oil is extensively used in preparing dry cake mix used for baking biscuits, cakes and sponge cakes, soaps, sauces, fat substitutes, etc. Recently, palm and kernel oils have been increasingly used as biodiesel fuel.

Types of Olive Oil
There are three main types of olive oils. They are classified into the following as per the International Olive Oil Council, a premier body which deals with olive

• The first type of olive oil is the Extra Virgin Olive Oil. This oil is rich in flavour and is the best quality. It is extracted by an process whereby the olives are first pressed or crushed to extract the liquid oil. This requires the least amount of processing
• The second type of oil used is the Virgin Olive Oil. It is extracted from the first pressing alone and is of a reasonably good quality.
• The third type is the Pure Olive Oil. This type of oil undergoes chemical treatment and other refining or filtering procedures so that the taste, flavour and the richness of olive oil is brought out. Refined and pure olive oils are combined in this process.
• Another heavily processed form of the oil is the extra light olive oil and it is different from the original to a large extent in taste and flavour.

A crunchy biennial plant, Celery is a herb in the Apiaceae family, which has been cultivated for centuries in various forms. It was primarily cultivated for its medicinal properties; but now it has become the part of daily diet of consumers around the world. All parts of a celery plant are edible and usable including the root, also known as celeriac, crisp stalks, seeds, and feathery green leaves. Its leaves are also used as seasoning in preparing many recipes.

Celery is a biennial plant in the family apiaceae, and is related to dill, carrots, fennel, and parsley. It requires deep, well drained soil with plenty of organic matter and a pH between 6.5 and 7.5. Its leaves are finely divided and light to dark green in colour. The flowers are creamy-white which are 2-3 mm diameter and produced in dense compound umbels. The seeds are broad ovoid to globose, 1.5-2 mm long and wide

Uses of Castor Oil

Food Industry: Food Grade Castor Oil is widely used in the food processing industry. It is used as food additives, lavorings, candy (i.e., chocolate), as a mold inhibitor, and also in packaging. The food stuff industries also use polyoxyethylated castor oil (eg. Cremophor EL) as a vehicle for oral and intravenous administration of water-insoluble compounds

Uses in Medicinal Science: From centuries, castor oil has been widely used as home remedy for many disorders. This unsaturated fatty acid contains ricinoleic acid, a unique subtance with great healing capabilities. Ricinoleic acid inhibits the growth of many viruses, bacteria, yeasts and molds. The most common and most frequent of the medical uses for castor oil are the way it is used for treating constipation. Application of the castor oil is also beneficial in cases of ringworm, keratoses, skin inflammation, abrasions, fungal infections, and acne. One study has found that castor oil decreased pain more than ultrasound gel or vaseline during extracorporeal shock wave application.

Canola oil is the preferred oil for use in both countries because it is the oil lowest in saturated fats. Canola meal is the by-product of canola oil processing. It is used as a high-protein feed ingredient in the rations of poultry, swine, cattle and fish.

These food and feed applications are possible through strict procedures used in the processing of canola seed into oil and meal. This document describes the processing methodologies that are used by the canola industry to produce high quality oil and meal products.

The production of edible vegetable oils including canola oil involves two overall processes, mechanical pressing and extraction, and further processing to remove impurities. The techniques used are similar for most vegetable oils produced from the seeds of plants. The crushing and extraction processes utilized by the canola industry today produce very little change to the fatty acid profile of the oil and the nutritional qualities of the meal.
