SCRAPING OF COCONUTS.

Shown above is an improved coconut scraping machine used for medium or large manufacturing process

DRYING OF SCRAPED COCONUT.

SCRAPED COCONUTS ARE DRIED . Moisture of coconuts is removed and oil should be felt when pressing by finger tip .

EXTRACTING OF VIRGIN COCONUT OIL.

Above method is suitable for domestic extraction of virgin coconut oil.However more improved machinary is used for medium and large scale production.

Special Scientific Processes.

2011-08-25T22:27:00.000-07:00

There are several scientific processes involved with manufacture of white coconut oil.

DEHYDRATION ; It is the process of removal of moisture from shred coconut .If coconut scrapings are not well or properly dehydrated the oil become rancid .It is done by sending steam through scrapings. The moisture content should be 0.5% maximum.

DOUBLE BOIL METHOD ; Water is filled to the vessel. Then oil is added and temperature is kept at 60 degrees maximum using a thermometer .Then it is heated for 10-15 minutes .

Scientific Explanation-The moisture particles in the oil sample is evaporated.

LABORATORY TESTINGS- There are 10 lab tests .Some of them are;

1. Moisture Content Test

2. FFA Content Value

FFA content the free fatty acid content .It should be 0.2% maximum. For any oil the free fatty acid content value should be of low value. The fats and oil or the triglycerides are digested in to the simplest form of fatty acid and glycerol. But in virgin coconut fatty acid are found freely. Our stomach can not digest fatty acid and thus digested in small intestine and liver. If the content of fatty acid is high, the acidity in digestive cavity can cause irritations. But in virgin coconut oil the Free Fatty Acid content is very low, thus reducing the above risk.

3. IV Value test(Iodine Value Test)

4. Refractive Index test.

For this test special equipment called Spectrophotometer is used. Using this experiment, a gas sample is placed on the device and a light ray is passed through it and refractive index is measured.

Process.

2011-08-25T00:56:00.000-07:00

There are several methods of production of virgin coconut oil .They are ;

C COLD PRESS METHOD

· CENTRIFUGAL SYSTEM

· FERMENTATION SYSTEM

Virgin coconut oil can be manufactured at room temperature.

COLD PRESS METHOD

1. Coconuts are selected .The factors concerned in selecting coconut is the age of coconut. Coconuts should be 3 weeks older after plucking.

2. The coconuts are husked ,scraped or shred in to tiny particles.When scraping , only the kernel should be shred and the bran should not be added.

3. Then the coconuts are dried for 1- 2 hours.For this, dryers can be used .For small scale industries , sun drying can be done for domestic purpose and also dehydration should be done as soon as possible. If not Salmonella develops on folds , colour changesand begin to sting.If they are dried up to suitable extent , if a coconut particle is pressed from finger tips, oil should be released.

4. Then the moisture of coconut scrapings is reduced to 8-10% by placing 3 hours in dryer or in sun and moisture meter is used for measuring the moisture while an oven can be used for domestic industry.

5. Press the dried coconut oil using the machines ( a modified string hopper mould can also be used.)

6. Filter the coconut oil.Still the coconut oil is having colour and is yellowish due to suspension of protein.For filtering

· Filter paper

· Blotting paper(according to size of coconut folds can be used)

· a clean cloth are suitable.

* Advantages of Cold Press Method is 300ml of virgin coconut oil can be obtained from 1kg of coconut.

* Cold Press Method is also beneficial as it has no high moisture content like fermented oil and doesn’t become rancid early.

Machinary

2011-08-24T22:36:00.000-07:00

1.SCRAPERS –Either manual or electric scrapers are used in domestic level while electric scrapers are used in medium or large scale industries .The function is scraping coconut to very minute shreds without addition of bran.

2.DEHYDRATORS- Drum Type Rotary Dehydrator.

Fuel is saw dust and combustion occur here.Water is sent through a pipe system in the boiler and saw dust is packed inside and subjected to combustion.Then water inside is boiled with no direct contact with saw dust preventing addition of impurities.Then the steam produced is sent through drum shaped rotary and coconut scraping are made to agitate and moisture is removed. Then remnant coconut scraping is obtained separately.

3.OIL EXTRACTING MACHINARY- There are of two sizes of 3 manual equipments.

· Domestic Machine-It can extract oil of only one coconut per once.Thus it is not efficient.

· Medium Scale Machine 1-It can extract oil of 5/6 coconuts at once.It is suitable for medium scale industries.It is worth Rs 19 000.00 Capacity is 750g of scraped coconut.

· Medium Scale Machine 2 –It can extract oil of 18 coconuts ,(2.2kg).It also is suitable for medium scale industry.It is Rs 85000.00 worth.It can be operatd by a hydrolic jak.

4.INDUSTRIAL LEVEL EXTRACTING MACHINE-

It runs by single phase current.It can extract oil of capacity of 700 coconuts a day.It needs an input of 15 kg scraped coconuts a day. It is operated by a motor.

4.DOUBLE BOILER-This is used for heating the scraped for 10-15 minutes.

OTHER MATERIALS NEEDED-         Filter papers
                                                    Blotting papers or cotton wool for
filtering.

Specificity of Virgin Coconut Oil.

2011-08-23T05:20:00.002-07:00

Virgin coconut oil contain all the nutrients that can be obtained from coconut oil, well preserved and protected.
It has no colour and is a clear oil because it contain no impurities.(sediment free)
The process of manufacturing also doesn't involve caramalysation.Caramalysation is the melting of sugar in coconut scraping .It 's due to this that normally coconut oil is yellowish.But virgin coconut oil is clear and pure.
It has natural ,fresh coconut scent , free from rancid and has 20% moisture and it is a volatile liquid preventing rancidity.
Virgin coconut oil is extracted from fresh coconut oil meat (not copra) by mechanical and natural means .It can be obtained with/without heat.
In order to protect the oil's essential properties , it doesn't undergo any chemical refinning ,bleaching and deodrizing.
Unlike common coconut oil it has high shelf life.and can be used in infant and baby food formulations,ice cream,frozen deserts and confectioneries , widely.
RDB oils are hydrogenated ; artificially pressed in to molecules to create oil with higher melting points.Trans Fatty acids in them are highly toxic.
MCFA in virgin coconut oil doesn't break / destroy at high temperature.Thus beneficial nutrients ara retained and not harmed.

Unique Qualities of Virgin coconut Oil

2011-08-23T05:20:00.000-07:00

Virgin coconut oil has special qualities in comparision to the normal traditional coconut oil .

Virgin coconut oil is

Rich in Vitamin E.
It is free from impurities and can be eaten raw without cooking.
It has features of an energizer such as glucose.
It has special ability of breaking / dissolving the lipo-protein envelope of some viruses such as HIV.
By scientific experiments , it is proved virgin coconut oil has a nutritional value equal to breast milk.
The virgin coconut oil manufacturing can be done under room temperature (25 degree Celsius) unlike other coconut oil types.
Normal coconut oil is saturated and has MCFA / good fats with 92% of saturated fatty acid content which causes health effects.But ,a recent discovery proves 62% MCFA is coconut oil .Unsaturated has high concentration of LCFA ,easily absorbed with less energy,few enzymes and improving digestion.
