Inca Inchi® – Sacha inchi oil

This study was carried out in 2007 by ITERG on flaxseed oil and virgin Inca Inchi® oil for a comparison of ALA metabolism and intestinal absorption rates in rats.

Rats were fed a fat-free diet and then underwent a surgical procedure under general anesthesia to sample lymph. Upon recovery from the procedure, rats were fed oil containing an internal standard via gastric intubation. The internal standard used was glyceryl tri-isopalmitate , a triglyceride whose absorption rate is close to 100% and whose fatty acids (three iso-palmitic acid molecules) are strictly exogenous. The lymph of each rat was collected in a single fraction for 24 h, covering the lymph production period.

The study was done on eight rats for each tested oil.

Therefore, the percentage of polyunsaturated fatty acids (PUFAs) absorbed by rats fed Inca Inchi® oil was higher than that of rats fed flaxseed oil.

ALA absorption rate

The relative proportions of ALA and iso-palmitic acid (the internal standard) were measured using gas chromatography in both tested oils (RF) and in the lymph samples (RL). The absorption rates (T) of ALA for each oil is calculated from the proportion of ALA in the lymph samples with respect to the proportion of ALA in the tested oils.

Therefore, the percentage of polyunsaturated fatty acids (PUFAs) absorbed by rats fed Inca Inchi® oil was higher than that of rats fed flaxseed oil.

ALA absorption rate

The relative proportions of ALA and iso-palmitic acid (the internal standard) were measured using gas chromatography in both tested oils (RF) and in the lymph samples (RL). The absorption rates (T) of ALA for each oil is calculated from the proportion of ALA in the lymph samples with respect to the proportion of ALA in the tested oils.

Structure of lymphatic triglycerides and ALA bioavailability

During digestion, triglycerides contained in food are only partially hydrolyzed by pancreatic lipase that acts specifically on the sn-1 and sn-3 positions. The fatty acids at the sn-2 position are not released, but are absorbed as 2-monoglycerides. Free fatty acids are easily oxidized and are not absorbed: the sn-2 position of ALA thus favors its absorption and metabolism.

Therefore, the distribution of ALA among the internal and external positions of lymphatic triglycerides can be a good indication of how well ALA is metabolized.

All of the results obtained during this study suggest that the metabolic potential of ALA contained in Inca Inchi® oil is equivalent to that of flaxseed oil. (ITERG, 2010).

Inca Inchi® oil is thus naturally stable and does not require the addition of any anti-oxidants.

The Food Safety Authority of Ireland declared that Inca Inchi® oil is substantially equivalent to flaxseed oil. This authorization is valid for all of Europe and can be consulted via this link.

Sacha Inchi is into the 3rd list of the Belgian Arrêté Royal of 29 June 1997. Thus, it can be authorized in France by mutual recognition by Article 16 of the French Decree 2006-352.

It is important to notify that the products containing Sacha Inchi have to be conformed to Novel Food Regulation n°258/97 and 2283/2015 to be authorized..

The reference daily intakes of ALA and LA are respectively 2 g and 10 g. They are defined in a 2009 EFSA opinion.

Virgin Inca Inchi® oil naturally contains 1900 to 3200 ppm of gamma- and delta-tocopherols.

It is thus naturally stable and does not require any anti-oxidants.
