3. PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it has to be performed.




TECHNICAL FIELD OF INVENTION:
The present invention relates to an efficient process of extracting oil from oil seeds in a good yield. More particularly the present invention relates to a process of extracting oil from oil seeds applying a blend of Bioenhancers and Antioxidants using sparging techniques to make an oil-extraction plant more viable and profitable by reducing the time and energy.
BACKGROUND OF THE INVENTION:
Normally, vegetable oils are obtained from germs, seeds and fruits by expelling and/or extracting with organic solvents in a continuous or discontinuous process. The pre-treatment or conditioning of the raw material is important for obtaining an economically justifiable yield of high quality oil. The aim of conditioning, in which the degree of mechanical crushing, the moisture content of the basic material, the temperature and the time are important factors, to facilitate the escape of the oil (in expelling) or the penetration of the extraction agent (in extracting) by destroying the plant cells and by causing thermal expansion of the cell contents.
Patent No. CA 1325220 discloses a process for extracting vegetable oil from an oil bearing material such as oil seeds, corn and the like. The process comprises adding a food oil of preferably the same type as will be extracted from the oil bearing material to form a slurry mixture. Selected enzymes present in the slurry are deactivated and the slurry is heated to a pre selected temperature for a pre selected period of time, preferably under a partial vacuum. This processing reduces the phospholipids and trace metal content in the oil extracted from the oil bearing material. The oil product produced is light in color, shows no turbidity and exhibits a minimal amount of phosphorus, calcium, magnesium and iron. The oil is ready for physical refining.
Patent No. W09113956 discloses a process for the preparation of a vegetable-oil product from oilseed, such as rapeseed, and the product obtained by the process. In the process the seed is comminuted, possibly heat-treated, and slurried in water. According to the
2

invention, an enzyme is added to this slurry, the purpose of the enzyme being to retain in the aqueous phase the phosphatides present in the seed, while the oil separates to form a separate phase of its own, which is separated mechanically by centrifugation, for example. The obtained crude vegetable oil, which does not contain organic solvent residues and is substantially devoid of phosphatides, is refined physically to produce a final product, the refining comprising a treatment with an adsorption agent and/or a deodorization.
The present invention improves the conventional processes of obtaining vegetable oil from low oil content seeds such as soya, or from high oil content seeds, such as the sunflower seeds, applying enzymatic treatment to the soya before and during the process of extraction with solvents and to the sunflower before the pressing. This treatment is carried out by multiple enzyme complexes: cellulase, glucanase, hemicellulase, pectinase and proteases which permit an easier release of the oil from the oil cells. The modification can be implemented over the existing installations without substantial changes in the conventional course of the operation. The enzymatic treatment results in predigested oil cake with residual flavour and oil which can be obtained during the process, which can be used as an animal alimentation.
OBJECTIVE OF THE INVENTION:
The main objective of present invention relates to the use of bioenhancers and
antioxidants using sparging technique to make an oil extraction plant viable and
profitable.
Another object of present invention relates to the fact that the properties of the oil
extracted after treatment with bioenhancers does not change the physical and nutritional
properties.
SUMMARY OF THE INVENTION:
The present invention discloses a process of extracting oil from oil seeds applying a blend of Bioenhancers and Antioxidants using sparging techniques thus making the oil-extraction plant more viable and profitable thereby reducing the time and energy and
3

improving yield of extracted oil and thus the deoiled cake obtained by above said process has more digestive property which is beneficial to the cattle feed industry.
DETAILED DESCRIPTION:
The present invention describes the energy saving, yield efficient process of extracting oil from oil seeds applying a blend of Bioenhancers and Antioxidants using sparging techniques to make an oil- extraction plant more viable and profitable. The application of blend of Bioenhancers and Antioxidants using sparging techniques on oil seeds increase the oil extractability and ultimately achieves reduction of oil in de-oiled cake also improve the digestibility of deoiled cake.
This step is inventive, over the conventional method in tapping the biochemical energy of
Bioenhancers and replacing the much costlier mechanical/ electrical energy. The use of
blend of bioenhancer and Antioxidants leads to
(i) Improving the quality of extracted oil by increasing its saturation value.
(ii) reducing the chances of rancidity in final extracted oil.
Use of Sparging technique enables uniform application of the blend of Bioenhancers and Antioxidants on the oil-bearing seeds thus yielding the better results.
Synergetic action of blend of Bioenhancers and Antioxidants are as follows: The gums/fibres bind the oil (fat) and protein in the seed. The perfect blend of cellulase, hemicellulase, pectinase, amylase and proteases which break the cell wall structure at different points on the cell and also cause loosening of fibers (gums) present in the seeds, improving the oil extraction process and ultimately leading to increased oil yield. This results in saving of energy during the stages of cooking of seed, flaking, solvent extraction, and during recovery of solvent in desolventizer toaster. At the same time, due to Antioxidants' action on seed, increase in the saturation value of extracted oil is observed, thus decreasing substantially the chances of rancidity in the final extracted oil.

Seed + blend of Bioenhancers and Antioxidants ►
(i) Reduction in energy and Time required for oil extraction
(ii) Increasing the oil yield
(iii)Quality of the oil (reduce the chances of rancidity and increases saturation
value of extracted oil)
The present invention claims the composition which consists of blend of bioenhancers and antioxidant wherein the said bioenhancers comprises especially cell wall degrading pentosanases which acts on pentosans like pectin, xylan, cellulose present in the cellular lining of the oil seed. The bioenhancers are formulated in conjunction with antioxidant like ascorbic acid, tocopherol, Butylated hydroxyl toluene, tertiary butyl hydroxyl quinone. The rate of action of bioenhancers and antioxidant agents is the synergistic effect of improving extracted oil yield as well as improving the shelf life of extracted oil by reducing the rancidity.
The present invention discloses process in which the blend of bioenhancer and antioxidants wherein the said bioenhancer comprising pentosanases such as Pentosanase - 0 - 5%, Antioxidants - 0 -1% with dextrin, maltodextrin as inert filler. (l)Bioenhancer The mechanism of bioenhancers can be exploited for the increase in yield of extracted oil
1. Bioenhancers break down the cell wall structures at different points on the cell wall of the oil seeds which improve the rate of oil extraction.
2. Bioenhancer Causes loosening of fibers (gums) present in the seeds, improving the oil extraction process and ultimately leading to increased oil yield
(2) Antioxidant
Antioxidants are the compounds used to preserve the food material such as oil, by retarding deteoriation, rancidity or discolouration due to oxidation reaction naturally occurring within the foods which involve the removal of electrons from atoms and molecules and lead to the reduction of recipient compound. Due to Antioxidants' action on seed cell wall, increase in the saturation value of extracted oil is observed, thus decreasing substantially the chances of rancidity in the final extracted oil. Thus the extracted oil has better shelf life by reducing rancidity.

According to the present invention, Bioenhancers were prepared by fermentation using controlled conditions with the help of pressure, adjustments in temperature and using suitable fermentation medium referring to the environment. The fermentation process is carried out by using the fermentation substrate and the carbohydrate source that is metabolized by the fermenting microorganism(s). The fermentation media includes fermentation substrate and other raw materials used in the fermentation process. In the present invention, the fermentation media can bring out liquefaction and saccharification processes or other desired processes prior to or simultaneously with fermentation.

Effect of blend of bioenhancer and antioxidant in improving the shelf life of oil by reducing rancidity.
The peroxide value of oil extracted after treatment with blend of bioenhancer and antioxidant and without treatment is compared. The oils after treatment with blend of bioenhancer and antioxidant is checked for its peroxide value after 1 month also.
The results are as follows:

Blend of bioenhancer and antioxidant dosage Peroxide value in milli equi /kg
0.1 0.54
0.2 0.48
0.3 0.37
0.4 0.28
0.5 0.19

Analytical process:
Determination of Saponification Value:
The saponification value is the number of mg of potassium hydroxide (KOH) to saponify the esters in 1 g of the sample and neutralize the free acids in 1 g of a sample.
Procedure:
Unless otherwise specified, proceed as follows: Weigh accurately about 1 g of the sample, transfer into an Erlenmeyer flask, add 40 ml of ethanol, and dissolve while warming if necessary. Add 20 ml of ethanolic potassium hydroxide TS, accrately measured, equip the flask with a reflux condenser, and heat in a water bath for 30 minutes while shaking the flask occasionally. Cool, add a few drops of phenolphthalein TS, and immediately titrate excess potassium hydroxide with 0.5 mol/1 hydrochloric acid. Perform a blank test, and calculate the saponification value by the formula
Saponification Value = (a-b)* 28.5 / weight of sample in gm
Where
a = volume (ml) of 0.5 mol/1 hydrochloric acid consumed in the blank test, b = volume (ml) of 0.5 mol/1 hydrochloric acid consumed in the test.
Determination of Acid Value:
The acid value is the number of mg of potassium hydroxide (KOH) required to neutralize
1 g of a sample.
Hereinafter in the Monographs, such specification as not more than 15 (Fats and Related Substances Tests) indicates that when determined as directed in the following procedure, the acid value is not more than 15.
Unless otherwise specified, proceed as follows: Weigh accurately the specified quantity of the sample given in the table, according to the acid value of the table, and, unless otherwise specified, add 50 ml of an ethanol ether mixture (1 : 1).
18

Dissolve while heating if necessary, and use this solution as the test solution. Cool, add a few drops of phenolphthalein TS, titrate with 0.1 mol/1 ethanolic potassium hydroxide until the pink color of the solution persists for 30 seconds, and calculate the acid value by the formula below. Before using the solvent, add 0.1 mol/1 ethanolic potassium hydroxide to the solvent until its pink color persists for 30 seconds, using phenolphthalein TS as an indicator.
Acid value = [vol of 0.1 M ethanolic KOH consumed/weight of sample] * 5.611
Determination of Iodine Number
In this experiment iodobromine adds to the double bond.
I Br
II
C = C + IBr fC-C
The Hanus solution (IBr in acetic acid) is added in excess. After the reaction is complete, excess iodobromine is reacted with iodide forming 12, IBr +1-012 + Br-, which in turn is determined by standard thiosulphate titration.
Warning: Be careful when handling the iodobromine solution. Treat any spill immediately with thiosulphate solution.
Reagents and Apparatus: Unknown sample, 0.2000 M Hanus solution, dichloro-methane,15% KI solution in distilled water, distilled water, 0.2000 M sodium thiosulfate, starchindicator, erlenmeyer flasks (3 x 500 mL), buret (50 mL), graduated pipette (2 mL), measuring cylinders (10 and 100 mL), volumetric pipette (25 mL), aluminium foil.
Procedure: Pipette out aliquotes (1.00 mL) of the unknown mixture into erlenmeyer flasks (500 mL) and add 10 mL of dichloromethane. With a pipet add 25.0 mL Hanus solution, cover the opening with aluminiumfoil and place your labelled flasks in the dark in the cupboard (under the fume hood) for 30 min. with occasionally shaking. Add 10 mL
19

of the 15% KI solution, shake thoroughly and add 100 mL of dist. water. Titrate the solution with 0.2000 M sodium thiosulphate until the solution turns pale yellow. Add starch indicator (3mL) and continue titration until the blue colour entirely disappears. Calculate the iodine number.
Determination of Specific Gravity:
The specific gravity is determined by specific gravity bottle method. Note down the weight of empty bottle, bottle filled with water and bottle filled with sample. Calculate the specific gravity of the given material as follows.
Specific gravity = (weight of bottle + sample) - (weight of bottle)
(weight of bottle +water) - (weight of bottle)
Determination of Protein Content:
The protein content of flour can be done by KJELDAHL METHOD. The total nitrogen can be determined as approximately 1.5 g. The crude protein can be calculated using the factor N* 5.7
Determination of peroxide Value:
Weigh accurately 4-5 gms or less when clearly rancid into a dry conical flask. Add 10 ml of chloroform. Dissolve the fat by swirling. Add 15 ml of glacial acetic acid and 1 ml of aqueous KI solution. Stopper the flask for 1 min in dark. Add 75 ml of distilled water and titrate liberated iodine against thio. Carry out the reagent blank which should not exceed 0.5mlof0.01Nthio.
