Problems solved by technology

[0018] In addition, this method, which appears to be very advantageous for the preparation of avocado oil intended for food or cosmetic applications, has major disadvantages for other applications: the method is selective and does not extract all possible unsaponifiable substances present in the fruit. thing
However, questions remain about their industrial development, the toxicity and chemical stability of the solvent or solvents used, and the feasibility of these methods from an economical and environmental point of view.
[0022] Also, because of the mechanical properties of this quality of fruit, the method of preparing avocado oil by drying avocados at higher temperatures and dehydrating them by pressing is not directly applicable to soft avocados
In fact, soft fruits are not suitable for the regular conditions of the cutting and drying operations normally used

example 1

[0164] Example 1: Extraction of oil from soft avocado fruit: Effect of particle size and pressing during grinding (1) (4) The effect of adding water (3) to previously dried avocados

[0165] 3 kg of soft avocados of the Aspen variety 18 gauge from Kenya were ground in a RETSCH knife grinder SM100 equipped with a sieve aperture of 20 mm, 10 mm or 1 mm, depending on the preferred particle size, with The hardness measured by the penetrometer is 0.1 to 0.3kg / cm 2 .

[0166] The ground product is stored at 0.158m with a thickness of 2cm 2 on the tray.

[0167] The trays were then placed in a ventilated heating room and dried with air circulation at 80±5°C for 72 hours.

[0168] The dried ground product was recovered and ground to homogeneity in a RETSCH model SM100 knife grinder equipped with a 20 mm aperture screen.

[0169] Residual moisture was measured by thermogravimetric method using IR drying.

[0170] After analysis, the milled product is then hydrated or not hydrat...

example 2

[0179] Example 2: Extraction of Oil from Soft Avocado Fruit Specifically Including Separate Grinding Steps of Different Parts of Avocado (1) and the effect of adding water (3) to dried avocados (2) before pressing (4)

[0180] 3 kg of soft avocados were depitted and depulped and then ground in two parts (pulp and pit+peel) according to the preferred particle size in a RETSCH grinder SM100 equipped with a sieve opening of 10 mm. The pears were obtained from Kenya as a 18-gauge Aspen variety, with a hardness of 0.1 to 0.3 kg / cm as measured by a penetrometer 2 .

[0181] The ground pulp fraction was remixed with its corresponding ground pit+peel fraction in the original ratio (analysis No. 7). The rest of the pulp was dried separately (analysis No. 6).

[0182] The different ground products are spread out on the tray with a thickness of 2 cm. The trays were then placed in a ventilated heating room and dried with air circulation at 80±5°C for 72 hours.

Abstract

The present invention relates to the use of whole soft avocados for preparing avocado oil rich in unsaponifiables, said unsaponifiables containing aliphatic acetogenins and / or derivatives thereof. Advantageously, the oil has an acid value of less than or equal to 3 mg KOH / g. The invention further relates to a method for preparing avocado oil rich in unsaponifiables from whole soft avocados, said unsaponifiables containing aliphatic acetogenins and / or derivatives thereof. The invention further relates to avocado oil which is rich in unsaponifiables and which can be prepared by said method. The invention further relates to the use of the avocado oil for preparing an avocado oil concentrate enriched with unsaponifiables, or avocado unsaponifiables that are rich in aliphatic furans. Finally, the invention relates to avocado unsaponifiables which are rich in aliphatic furans or to an avocado oil concentrate which is enriched with unsaponifiables, and which can be prepared from said avocado oil, for the use thereof as a drug, advantageously for the prevention and / or treatment of disorders of the conjunctive tissue, such as arthrosis, joint conditions, such as rheumatism, or periodontal diseases, such as gingivitis or periodontitis.

Description

technical field [0001] The present invention relates to the use of whole soft avocados for obtaining avocado oil rich in unsaponifiables. Advantageously, said unsaponifiables comprise aliphatic polyacetylenes and / or derivatives thereof. In particular, the oil has a low acid number, typically less than or equal to 3 mgKOH / g. The invention also relates to a method for obtaining avocado oil rich in unsaponifiables, advantageously comprising aliphatic paraacetyls and / or derivatives thereof, from whole soft avocados. The invention also relates to the avocado oil enriched in unsaponifiables obtainable by said process. The invention also relates to the use of avocado oil for the preparation of an avocado oil concentrate enriched in unsaponifiables or an avocado unsaponifiables enriched in aliphatic furans. Finally, the present invention relates to avocado unsaponifiables enriched in aliphatic furans or avocado oil concentrates enriched in unsaponifiables obtainable from said avoca...
