Description
DESCRIPTION
METHOD FOR REMOVING GOSSYPOL
FROM THE COTTONSEED
FIELD OF ART
The invention relates to the field of human needs and specifically to the field of food. Even more specifically to the field of animal feed and in particular to the field of feed for animals from material of plant origin, such as for example from roots, seeds or hay. Specifically, it relates to a method of removing gossypol from cottonseed and cottoncake for animal feed production. It further relates to a method of producing gossypol powder and cottonseed oil.
BACKGROUND OF THE INVENTION
The method disclosed in the present invention for removing gossypol from cottonseed and cottoncake has not been disclosed in the prior art.
Cottonseed is a by-product, which until today cannot be used as food for monogastric animals or even for humans, because it contains a toxic plant substance, gossypol, which in certain concentrations causes various side effects, such as sterilization.
Gossypol is a highly toxic polyphenolic compound found in cotton (genus Gossypium) and especially in its seed. Its concentration in cottonseed varies and can exceed 7.000 and 14.000 mg/kg, as free and total gossypol, respectively. Its free form is the biologically active one and is responsible for its toxicity. For the above reason, free gossypol should be removed, reduced and/or inactivated - degraded from cottonseed products (e.g. flours, placentas and oils) intended for animal feed and human food.
According to the European legislation in force, the concentration of free gossypol in cotton seed and cotton placenta / cotton flour may not exceed 5.000 and 1.200 mg/kg (ppm), respectively. In addition, the concentration of free gossypol in the final rations of production animals depends on the species of animal and starts at 20ppm for laying hens and reaches up to 500ppm (there are newer proposals for 700ppm) for ruminants.
To inactivate and reduce gossypol from cottonseed and its products, various technological applications have been studied, such as thermal treatment combined with steam and pressure, use of ethanol or isopropanol steam, use of ozone and radiation, solid phase fermentation processes, as well as nutritional interventions through the addition of ferrous sulfate, sodium selenate and vitamin E.
From the relevant literature it appears that out of the technological processes that have been studied for the reduction of free gossypol, thermal treatment currently has the possibility of effective application on a production scale. Thermal treatment combined with steam and processes of swelling and extrusion of the cotton seed and cotton placenta (after extracting the oil) seem to give the best results with the residual free gossypol being significantly reduced and in the best processes being less than 0,2%. Of course, the final result also depends on the oil extraction procedures, as a significant percentage of the free gossypol can be removed with the oil, which must then be purified. At this point it should be noted that during heat treatment the free gossypol reacts with amino acids of the cottonseed protein and mainly 4-lysine and turns into a conjugated - non-toxic form. The aforementioned inactivation of free gossypol, with the methods applied to date, unfortunately degrades the biological value of the protein and, by extension, its dietary value.
The development of new methods-procedures for processing cotton seed or cotton cake with the aim of producing safer and better quality products for consumption by humans and animals is of particular interest, especially in times when the cost of the main animal feed is increasing rapidly. The new processes should be on the one hand more economical than the existing ones, in order to be able to be applied on a large scale, and on the other hand to reduce free gossypol to a greater extent. In addition, when developing new processes, it is advisable to take into account the preservation and if possible the improvement of the nutritional characteristics of the products produced. Possible requirements for the simultaneous reduction of other anti-dietary agents (e.g. mycotoxins) that may be present in the cottonseed should also be taken into account. Finally, the new process-methodology should be able to be optimized and customized per
application case in order to be able to be integrated into a larger range of production facilities.
It is thus an object of the present invention to advantageously address the aforementioned disadvantages and shortcomings of the prior art by proposing a new method of removing gossypol from cottonseed or cotton cake.
It is a further object of the present invention to provide a method of removing gossypol from cottonseed, which provides a cottonseed meal with minimal toxicity, preferably below 200ppm.
A further object of the present invention is to provide a method of removing gossypol from cottonseed or cottonseed cake, which provides a protein with good convertibility in the body and thus good nutritional value.
A further object of the invention is to provide a new method of removing gossypol from cottonseed, which allows the production of good quality oil.
A further object of the invention is to provide a method for removing the plant toxic substance of free gossypol, so that it can be included in the diet of both humans and monogastric meat production animals.
Another object of the invention is to obtain separate by-products, such as gossypol powder, cottonseed oil, pure fiber and hulled fiber, which can be further used in different industries and applications.
An advantage of the present invention is also the recycling and separation of water from the toxic substance of gossypol, thereby reusing it in the process.
These and other objects, features and advantages of the invention will become apparent in the following detailed description.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
By describing exemplary embodiments of the use of the method, it will be sought to understand the method of removing gossypol from cottonseed or cotton cake and the advantages it presents.
The raw material used is cottonseed or cotton cake, which is crushed. For crushing, a 6 mm crushing silo is indicatively used, but this is not limiting. Crushed cottonseed
consists of cotton seeds, which make up the crumb, and cotton fibers, the two materials being separated from each other by sieving. Cotton fibers are separated into hulled fibers and pure fibers. Hulled fibers are stored for sale as animal feed, while pure cotton fibers are stored for sale separately.
The cotton seed is transferred to a stirring and boiling tank. There it is enriched with water, while at the same time it is stirred to create a slurry, which boils at temperatures from 60 to 105 °C. By way of example, the enrichment in water is approximately 130% of the quantity of the seed. The massage lasts approximately 25 minutes, the ideal temperature being 95 °C. The slurry that has been produced is transferred to a separator for its separation, through centrifugation. This process takes place in a three-phase horizontal centrifugal separator, at different speeds. The purpose of the centrifugation is to remove the water that is now impregnated with the essence of free gossypol, while at the same time two other products are obtained, the oil of the cottonseed and its fresh crumb. The fresh and gossypol-free seed must be dried and that is why it is first taken to a vertical dryer, where it is dried, approximately at 180°C, without the temperature being restrictive. It is then sent to a horizontal cylindrical dryer, for gentle freezing of the seed, before its final storage, in a floury texture, without containing the toxic plant substance of gossypol.
Accordingly, the solution created during centrifugation, which contains both cottonseed oil and water, is sent for further separation, indicatively in a vertical centrifugal separator, so as to obtain cottonseed oil, without moisture, which can be put into the market as a final product.
The water that has been separated during the centrifugation of the slurry, as well as the water from the separation of the oil, is rich in the plant toxin gossypol. For this reason, they are led and mixed in a condenser, where clean, environmentally friendly water is obtained from the condensate, which is used in the remaining stages of the process, as described above, and concentrated water with gossypol. This intermediate product is further dehydrated, preferably in a cylindrical dryer, in order to obtain a powder from the plant toxic substance of gossypol, which can be put into other uses, such as for example in pharmaceutical applications.
It should be noted at this point that the description of the invention was made with reference to indicative embodiments to which it is not limited. Consequently, any change in the steps of the method, in the conditions of its application, in the order in which they are applied, as long as they do not constitute a new inventive step and do not contribute to the technical development of what is already known, are considered to be included in the aims and objectives of the present invention as summarized in the following claims.
