Abstract

Sacha Inchi (Plukenetia volubilis Linneo, Euphorbiaceae) is known as a Peruvian seed containing a high level of unsaturated fatty acids, such as α-linolenic acid (Omega-3), linoleic acid (Omega-6), and oleic acid (Omega-9). These essential fatty acids are important functional foods due to their benefits for human health. Considering its benefits, it is necessary to find the right cultivation conditions to develop Sacha Inchi in Indonesia, where it has not been widely cultivated. This study aimed to determine the adaptability of Sacha Inchi to different cultivation conditions and the effects of these conditions on seed production and oil quality. Sacha Inchi plants were cultivated under three different cultivation conditions (open area, mixed cultures, and agroforestry) and the seeds were harvested monthly to determine the seed production and oil quality. The results showed that seed production in the open area was higher than in other conditions. The highest oil yield from monthly harvesting was found in mixed cultures. Interestingly, the level of Omega-3 content in the agroforestry condition was higher compared to other conditions. The level of Omega-6 and Omega-9 content in the open area was higher than in mixed cultures and agroforestry. However, the content of unsaturated fatty acids in the three different cultivation conditions was not significantly different, being 91.88% in the open area, 92.53% in mixed cultures, and 92.97% for agroforestry. In conclusion, the cultivation of Sacha Inchi under open areas is recommended due to its seed productivity which will affect the total oil production.

Highlights

Humans can synthesize all lipids except those that are long-chain fatty acids (FAs), which are grouped into three omega-families: Omega-3, Omega-6, and
Alpha-linolenic acid (ALA) and linoleic acid (LA) are members of the Omega-3 and Omega-6 families, respectively, and are essential FAs as they cannot be produced by mammalian cells and must be obtained from the food in sufficient proportions [3]

Summary

Introduction

Dietary lipids are required by the human body since they are an important component of all living cells. Humans can synthesize all lipids except those that are long-chain fatty acids (FAs), which are grouped into three omega-families: Omega-3, Omega-6, and. Omega-3 and Omega-6 are polyunsaturated fatty acids (PUFAs), whereas the majority of the Omega-9 FAs are monounsaturated fatty acids (MUFAs) [2]. Alpha-linolenic acid (ALA) and linoleic acid (LA) are members of the Omega-3 and Omega-6 families, respectively, and are essential FAs as they cannot be produced by mammalian cells and must be obtained from the food in sufficient proportions [3]. Oleic acid (OA) is a member of the Omega-9 family and a non-essential FA which can be produced naturally by the body in the presence of enough Omega-3 and Omega-6 [4].
