Virgin Coconut Oil

Coconut oil obtained from coconut milk is called virgin coconut oil. Traditional and modern methods are available for the manufacture of virgin coconut oil. In the traditional method, milk extracted from grated coconut kernel is boiled to get oil. Of late, the traditional method has been partially mechanized using a bridge press and mechanical grater. The modern method of extracting oil from fresh coconut kernel is known as wet processing.

The Virgin coconut oil is considered superior for use as edible oil, hair oil and baby oil because of its pleasing aroma and purity. It is applied on the body of babies to protect from skin diseases. Because of its low FFA content, this oil has a longer shelf life.

Coconut milk is obtained by extraction of fresh coconut wet gratings with or without water. This is an instant product, which can either be used directly/diluted with water to make various preparations such as fi sh & meat dishes, curries, sweets, deserts, puddings, cocktails, cakes, cookies, coconut jam, ice creams etc. It can also be used in the manufacture of bakery products and for coconut milk fl avouring food stuffs. Preserved forms of coconut milk such as canned cream or milk and dehydrated whole milk are now available in many coconut growing countries. Commercial production of these products has been promoted in the Philippines, Thailand, Indonesia, Western Samoa, Sri Lanka and Malaysia and to some extent in India. Indonesia is the leading exporter of coconut milk followed by Sri Lanka, Thailand and Philippines.

Coconut Skimmed Milk

plant protein and is an invaluable material for the preparation of milk substitutes. Coconut skimmed milk is a solution of the soluble components of coconut after the cream is separated in a cream separator. Skimmed milk is a good source of quality protein suitable for the preparation of many useful food products or as supplemental protein source, especially in regions deficient in animal proteins. Freshly prepared coconut milk from pared kernel is filtered through a 120 mesh vibrating screen and the pH of the filtered milk is raised from 6.3 to 7.0 with the additions of sodium hydroxide. The milk is then pasteurized at about 60oC for one hour and subsequently centrifuged in a cream separator to yield the aqueous phase or the protein rich skimmed milk.

Spray Dried Coconut Milk Powder

Spray drying is the best method for the preservation of coconut milk. Spray dried coconut milk powder is reconstituted into coconut milk by adding water which can be used to make various food preparations.

Coconut Oil

Coconut oil is rather a unique cooking oil as it contains the short and the medium chain saturated fatty acids. It fi nds extensive use in the food industry due to its characteristics such as easy melting behaviour, resistance to oxidative rancidity, pleasing fl avour and good digestibility. Coconut oil has gained importance as a dietary fat because of its high content of lauric acid, the source of monolaurin in the body and 16W content of Omega 6. It can be used for manufacturing margarine and shortenings. Coconut oil is preferred as a fat in the preparation of fi lled milk, infant milk powder, ice-cream and confectionery and bakery products. Because of its stable character, coconut oil is the preferred fat for deep frying.

Studies undertaken by the Biochemistry Department, University of Kerala showed that coconut oil:

  • Does not elevate blood total cholesterol and increases blood HDL cholesterol
  • If consumed along with coconut kernel, lowers blood cholesterol
  • Does not elevate LDL cholesterol or LDL cholesterol/HDL cholesterol ratio
  • Decreases serum triglycerides
A large number of branded coconut oil in consumer packs are marketed in the country. Coconut oil is refi ned for industrial use. The refi ned coconut oil is water white in colour with no aroma. Since coconut oil has the lowest level of unsaturated fatty acids among all vegetable oils, the cost of hydrogenation is much less than all other oils.

Coconut Shell Based Products Back to Top

Coconut Shell Powder

Coconut shells free from contamination of coir pith, etc., are broken into small pieces and fed into a pulveriser. The powder from the pulveriser is fed into a cyclone and the parallel product is collected in bag filters. The shell powder is then fed into a vibrating sieving machine and packed according to mesh size requirements for various end uses. The rejects from the sieving machine can be recycled in the pulverizer for size reduction. The main requirements for consistent good quality of coconut shell powder are proper selection of shell of proper stage of maturity and efficient machinery.

Coconut Shell Charcoal

Shell Charcoal is obtained by burning the shell of fully matured coconuts with a limited supply of air so that they do not burn away to ash but are only carbonized. The manufacture of shell charcoal shows from the coconut shell has become a very important economic and commercial activity. Furthermore, coconut shell charcoal, which was relatively a minor product in the past, has now developed into a general commercial commodity due to its intrinsic value as a raw material for the manufacture of activated carbon. Coconut shell charcoal are of two types: viz Coconut shell charcoal and granulated shell charcoal.

The quality standards for shell charcoal as per Asian and Pacific Coconut Community (APCC) are as follows:
Moisture Less than 10%
Ash Not more than 2%
Volatile matter Not more than 15%
Fixed carbon Not more than 75%
Foreign matter Not more than 0.5%
Colour Black
Size Not more than 5%, shall passa 0.63 cm mesh sieve.

Activated Carbon

The process of activation is carried out in two stages. Firstly the coconut shell is converted into shell charcoal by carbonization process which is usually carried out in mud-pits, brick kilns and metallic portable kilns. The coconut shell charcoal is activated by reaction with steam at a temperature of 900oC -1100oC under controlled atmosphere in a rotary kiln. The reaction between steam and charcoal takes place at the internal surface area, creating more sites for adsorption. The temperature factor, in the process of activation is very important. Below 900oC the reaction becomes too slow and is very uneconomical. Above 1100°C the reaction becomes diffusion controlled and therefore takes place on the outer surface of the charcoal resulting in loss of charcoal.
