BR102018074782A2 - process of obtaining raw material for the production of tocopherols / phytosterols / squalene / carotenoids and tocotrienols - Google Patents

Abstract

this invention deals with a process for obtaining the distilled extract (ed), from a specific evaporation process, which may have a next stage of stereification. in particular this invention allows the use of the biodiesel production process to obtain ed. this process of obtaining described in this invention allows the use of a new raw material (distilled extract - ed), alternatively the only source of raw material of natural origin which is ddov, for the production of tocopherols and sterols, and which currently has very low availability. technically, in the middle of the process of obtaining biodiesel it will be possible to install an evaporator specially sized to remove the ed, so as to enable the production of tocopherols, carotenoids, squalene, phytosterols and tocotrienols apart from a source of raw material natural, that currently due to the problem of availability of ddov, these products are very scarce.

Description

PROCESS OF OBTAINING RAW MATERIAL FOR THE PRODUCTION OF TOCOPHEROLS / PHYTOSTEROLS / SQUALENES / CAROTENOIDS AND TOCOTRIENOS.

DESCRIPTIVE REPORT

FIELD OF THE INVENTION

[001] Tocopherols (vitamin E), carotenoids (vitamin A), phytosterols, squalene and tocotrienols, derived from raw materials with their natural origin are obtained through the residue from the refining process of edible oils.

[002] This residue has very limited availability worldwide, and is known as Deodorized Vegetable Oil Distillate (DDOV or VOD).

[003] As the amount of biodiesel in Brazil is very large, mainly from Soy, the purpose of this invention is to develop a new alternative of raw material that has greater availability for the manufacture of the products mentioned in the title of this patent.

[004] Such innovation belongs to the field of activity of biotechnology, which, after research, found an alternative to obtain this raw material through the biodiesel manufacturing process.

[005] We will call this raw material distilled extract, which after obtaining it, will be processed by a molecular distiller to obtain the products mentioned in the title.

[006] Such products will have their applications for the pharmaceutical, nutraceutical, cosmetic, human food and animal feed industries.

[007] The invention registered under number BR1020120233983A2 of 17/09/2012 deals with the segregation and purification of the components of VOD Distilled Vegetable Oil, which are also tocopherols and sterols, obtained from the deodorization of

2/5 refined vegetable oil, but it does not deal with the use of raw material obtained through the production of biodiesel to obtain tocopherols and sterols.

[008] The invention registered under number PI0900438-6A2 of 06/02/2009 deals with the use of sterols and tocopherols obtained from the refining of soybean oil in the development of functional cardioprotective and cholesterol-reducing foods, but does not address the use of raw material obtained through the production of biodiesel to obtain tocopherols and sterols.

GENERAL DESCRIPTION

[009] Tocopherols, phytosterols, carotenoids, tocotrienols and equalene (all these products are unsaponifiable material) obtained from natural origin, use DDOV as a raw material in its manufacture, which has a very limited availability, thus configuring a great problem.

[010] This raw material (DDOV or VOD), which is obtained through the refining process of edible oils, represents only about 0.3 - 0.8% of the total amount of refined oil.

[011] The removal of DDOV in the process of refining edible oil, aims to remove the characteristic odor, which for food purposes, is very inconvenient.

[012] However, after discovering that DDOV can be used for the extraction of vitamins and their derivatives, some oil refining companies adapted their process in order to try to obtain higher concentrations of DDOV to be extracted from the refining process of edible oil . The big problem is that DDOV provides the antioxidant effect to edible oil, and it was observed that extracting DDOV in larger quantities, the final product (edible oil), had its useful life reduced, as it oxidized easily. Thus, as this was not the focus of oil producing companies, this adaptation was abandoned.

[013] In the case of this invention, a new raw material (distilled extract - ED) is extracted from the production process of biodiesel or substances with

3/5 similar molecular chains. This extraction is done from an evaporator specially designed in terms of efficiency and dimensions. For this description we will use biodiesel as an example, and the application of this process has no influence on the final quality of biodiesel, thus making it possible to take advantage of the abundance of Brazilian biodiesel to solve the current problem of lack of availability of DDOV obtaining tocopherols, phytosterols , carotenoids, tocotrienols and squalene (all of these are classified as unsaponifiable matter).

[014] The biodiesel extraction process modified by this invention, consists of 07 stages, according to figure 1, which shows the macro scheme of biodiesel manufacture, with the addition of the evaporation stage for extraction of ED. Below are the more detailed stages:

[015] Step 1 - It is the stage where the crude oil starts from the oil extraction process;

[016] Stage 2 - Stage in which the degumming of the crude oil is made, to obtain the degummed crude oil;

[017] Step 3 - This degummed crude oil is submitted to the neutralization process to remove the sludge, which is a residue of the process;

[018] Step 4 - After removing the sludge, a clarification is made with clay, which after the process is removed and considered as used clay;

[019] Step 5 - This is the step where the specially designed evaporator is introduced to extract the ED;

[020] Step 5 characterizes the additional step related to the invention for removing ED, which is best described in the substeps below, which is represented by Figure 2:

[021] Step 5.1 - Dexodidation Process, for removing oxygen and also drying the product, in order to avoid oxidation of the oil and increase in acidity;

[022] Step 5.2 - Circulation and recirculation process of the oil, combining vacuum and temperature, to allow the gradual extraction of the ED, which are the

4/5 unsaponifiable materials + free fatty acids (AGL);

[023] Step 5.3 - Chemical esterification, using sodium methylate and other equivalent substances, to allow separation of the unsaponifiable materials of the AGL.

[024] Note: Step 5.3 is optional.

[025] Step 6 - An esterification was performed to remove glycerin;

[026] Step 7 - After esterification and removal of glycerin, biodiesel is obtained;

[027] It is important to note that the basis of this research was the search for obtaining a raw material from plant origin, with the goal of also enabling the increase in the antioxidant power of the final product when compared to the same products of synthetic origin. It is also a fact to highlight that this idea is fully aligned with the population's growing search for products with natural origin, which tends to grow a lot in the coming years.

[028] For this invention, and step 5 was carried out from different types of evaporators. However, this invention is not restricted only to the evaporators used, but can also be used from other evaporators with similar effect.

PREFERRED EMBODIMENTS

[029] The first preferred modality for this invention, is obtained from descending film evaporation in specially designed equipment, followed by an esterification (step 5.3), to increase the concentration of unsaponifiable matter in the ED, separating the AGL. This process, has a short residence time, also has a small differential of the heating temperature, uses a thin film descending through gravity. These characteristics mentioned do not affect the quality of the evaporated material.

[030] The second preferred modality consists of the inventive process described above applied to the extraction of ED from the biodiesel production process.
