Problems solved by technology

[0013] Therefore, when conventional refining methods including de-sticking, neutralizing, decolorizing, freezing and deodorizing are carried out, various treatments are not effective enough to ensure that unstable compounds are completely removed, or that they are not degraded into secondary derivatives

Embodiment 1

[0166] Raw materials: It consists of fresh avocados of the Fuerté variety, of South African origin. The average amount of oil in fresh avocados is 16% by weight.

[0167] Dried fruit: 20 kilograms (kg) of whole fresh avocados were sliced ​​into 2 millimeter (mm) to 50 mm slices using a disc knife and distributed in trays at a thickness of 4 centimeters (cm) to 5 cm. Drying was carried out in a thermally regulated oven at a temperature of 70° C. for 48 hours. Then, the dried fruit was ground in a drum mill. The recovered dry fruit weighed 5.56 kg, ie 27.8% of the raw material.

[0168] Oil extraction: This operation is carried out in a laboratory press of Komet type. The extracted oil was filtered in a Buchner flask and then stored under nitrogen, away from light and moisture. The extraction yielded 1750 g of unrefined avocado oil, ie 31.5% of the dried fruit used.

[0169] The obtained unrefined oil was divided into two parts, and two comparative refining experiments were...

Embodiment 2

[0223] Comparative analysis of the glyceride composition of the oil obtained by the method of the present invention and the oil obtained by the method of the prior art including cold-press extraction and chemical refining:

[0224] Trials 1 and 2 were compared to two oils of the invention starting from two different raw materials using the method described in Example 1.

[0225] Samples 1 and 2 are samples of commercially available prior art oils.

[0226] A comparative analysis of the glyceride compositions is shown in Table 1 below.

[0227] Table 1

[0228] product

[0229] These comparative analyzes demonstrate the effect of using molecular distillation to prepare Test Oils 1 and 2 (as described in Example 1) on fractionating avocado oil glycerides. This method demonstrates removal of partial glycerides (mono- and diglycerides) and enrichment of triglycerides.

Abstract

Process for obtaining triglyceride rich refined avocado oil, comprises controlled dehydration of fresh avocado fruits having undergone preliminary transformations preferably at -50-120[deg]C, extraction of the oil from the dehydrated fruits, fractionation of oil to its triglyceride rich fraction and refining of the triglyceride rich oil fraction. Independent claims are included for: (1) the triglyceride rich refined avocado oil comprising a unsaponifiable fraction rich in sterols; and (2) a composition comprising the triglyceride rich avocado oil at 5-95 wt.%. - ACTIVITY : Dermatological; Cardiovascular-Gen; Antiarthritic; Osteopathic; Antirheumatic; Antiinflammatory. - MECHANISM OF ACTION : None given.

Description

technical field [0001] The present invention relates to a process for preparing refined avocado oil rich in triglycerides. The invention also relates to the refined triglyceride-rich avocado oil obtained by said method. Advantageously, the refined avocado oil of the present invention comprises a sterol-concentrated unsaponifiable fraction. Advantageously, the refined avocado oil of the present invention is substantially free of acetogenins and furan lipids. The invention also relates to compositions comprising said oil. The invention also relates to the pharmaceutical, dermatological, cosmetic or nutraceutical use of such compositions for human or animal use. Background technique [0002] Avocados, which originated in Mexico, were brought to Europe by the Spanish conquistadors. The fruit became a very popular food. Avocados are rich in oil, as lipids make up 10 to 20 percent of the fresh fruit. A high fat content is one of the characteristics of said fruit. The oil, w...
