Embodiment 1

[0150] Composition of Soybean Deodorized Distillate

[0151] The market for oils, more particularly soybean oil and DD, is severely constrained by the global availability of seeds and the growing need to develop vitamin E and phytosterols relevant to food, cosmetic or pharmaceutical applications.

[0152]This need has prompted the oil industry to optimize the deodorization process in order to obtain DD with a composition that is very conducive to the recovery of the unsaponifiable fraction.

[0153] Modifications made to the deodorizing plant were mainly aimed at increasing the deodorizing temperature and installing specific condensers capable of collecting a deodorizing distillate particularly rich in tocopherols and phytosterols.

[0154] It is this quality of DD that will preferably be addressed by the new invention.

[0155] As an example, the composition of a deodorized distillate of soybean is as follows:

[0156]

Embodiment 2

[0158] Distillation of deodorized distillates from soybeans

[0159] In the case of DD with a reduced concentration of unsaponifiables, the process of the invention can advantageously comprise a pretreatment by molecular distillation. It is applied to eliminate a portion of the light fraction of DD, mainly composed of fatty acids, in order to obtain the unsaponifiable-rich feedstock used in the process.

[0160] The test was carried out on a centrifugal molecular still with a maximum capacity of 25 kg / hour. The device consists of the following elements:

[0161] A conical circulating rotor with a diameter of 38 cm,

[0162] A water circulation coil (condenser),

[0163] Two recovery tanks for residue and distillate,

[0164] An induction heating system.

[0165] The vacuum unit consists of a vane pump (low vacuum) and an oil diffusion pump (molecular vacuum).

[0166] The product to be treated is first pumped into a continuous degasser consisting of a thin film, falling ...

Embodiment 3

[0175] Distillation of the deodorized distillate of sunflower

[0176] The test was carried out on the same apparatus as in Example 2.

[0177] The parameters used for this operation are as follows:

[0178] Feeding rate: 18.5kg / h

[0179] Vacuum degree: 10 -2 mmHg

[0180] Distillation temperature: 100°C

[0181] Distillation rate: 82.5%

[0182] Composition of the product:

[0183] Compound in g per 100g

Abstract

The invention relates to the use of at least one coproduct of the vegetable-oil refining industry for obtaining a purified total unsaponifiable vegetable oil product which is free of the impurities initially found in said coproduct, and which is advantageously free of sapid and odorant compounds and / or of chemical compounds resulting from the breakdown and decomposition of vegetable oils. The invention also relates to a method for obtaining a purified total unsaponifiable vegetable oil product from at least one coproduct from the vegetal-oil refining industry. The invention also relates to a purified total unsaponifiable vegetable oil product that can be obtained by said method, and to compositions containing such an unsaponifiable product. The invention further relates to such unsaponifiable products or such compositions for the use thereof as a drug, medical device, dermatological agent, cosmetic agent, or nutraceutical agent for humans or animals.

Description

technical field [0001] The present invention relates to the use of at least one by-product of the vegetable oil refining industry for obtaining purified total unsaponifiables of vegetable oils free of the impurities originally present in the above-mentioned by-products and advantageously free of taste and / or odorous compounds and / or are free of chemical compounds caused by the deterioration and decomposition of vegetable oils. The invention further relates to a process for obtaining purified vegetable oil total unsaponifiables from at least one by-product of the vegetable oil refining industry. The invention further relates to purified total unsaponifiables of vegetable oils obtainable by this method, and compositions containing said unsaponifiables. The invention further relates to said unsaponifiables or said compositions for use as human or animal medicine, medical device, dermatological agent, cosmetic agent or nutritional agent. Background technique [0002] After a s...
