Introduction

Sacha Inchi, also known as the "Inca Peanut," is a seed crop from the Amazon regions of Peru, Ecuador, and Brazil. Indigenous people have eaten it for its great nutrition. Recently, it has become popular worldwide as a superfood and eco-friendly crop. With more people wanting plant-based oils and proteins, Sacha Inchi oil and seeds are a strong alternative to regular crops. They are becoming important in markets for health supplements and sustainable foods. This review covers what we know about Sacha Inchi's nutrition, health benefits, how it's grown, and its economic value.


Botanical Description

Plukenetia volubilis, part of the Euphorbiaceae family, is a long-lasting climbing plant known for growing quickly and producing many seeds. It grows well in tropical areas with warm temperatures (20°C to 30°C) and plenty of rain (1,500 to 2,500 mm per year). Sacha Inchi has big, divided leaves and small white to yellow flowers that turn into pods with 10-15 seeds each. The seeds are oval, flat, and covered in a fiber layer, from which Sacha Inchi oil is made. The plant is tough against pests and diseases and can grow in various soil types, making it a great choice for eco-friendly farming.


Literature Review

  • Nutritional Profile of Sacha Inchi

    Many studies show that Sacha Inchi seeds and oil have outstanding nutrition. Smith and Perez (2022) found that Sacha Inchi oil has 48-60% alpha-linolenic acid (ALA, ω-3), which is more than what is in flaxseed oil. Also, Sacha Inchi seeds have 30-35% protein, similar to soybeans (Smith & Perez, 2022; Lee & Kim, 2020). But, Sacha Inchi has a better mix of amino acids, especially lysine, making it a better protein source (Gonzalez et al., 2021).

    Compared to flaxseed and chia seeds, Sacha Inchi has more ALA. Flaxseed oil has about 50-60% ALA, like Sacha Inchi, but Sacha Inchi has more ALA than chia seeds, which have around 30-35%. Plus, Sacha Inchi has a better balance of omega-6 to omega-3 fats, which helps reduce inflammation in the body.

  • Health Benefits

    Many studies look at the health advantages of Sacha Inchi. Gonzalez et al. (2021) showed that the omega-3 fats in Sacha Inchi oil lower triglycerides and blood pressure, which improves heart health. Also, Lee and Kim (2020) discovered that regularly using Sacha Inchi oil protects the brain, improves thinking, and slows down memory loss as people age.

    Comparison with Other Plant Proteins

    Sacha Inchi has slightly less protein than soybeans (36-40%), but its amino acids, especially lysine, are better. This makes Sacha Inchi a more complete protein for plant-based diets.

  • Agricultural Practices and Sustainability

    Alvarez and Torres (2023) highlighted how important eco-friendly farming methods are for growing Sacha Inchi. They found that using integrated pest management (IPM) and organic fertilizers helps keep the soil healthy and produces high-quality crops. Sustainable farming boosts productivity and helps protect the Amazon rainforest environment (Alvarez & Torres, 2023).

  • Economic Potential

    Sacha Inchi has great financial potential, especially in new markets for health supplements and eco-friendly foods. Lee and Kim (2020) pointed out that South American countries can become top exporters of Sacha Inchi products if they build strong supply systems and meet global quality standards.


Methodology

We performed a thorough review of scientific papers to study Sacha Inchi's nutrition, health benefits, farming methods, and economic value. We searched databases like PubMed, Google Scholar, ScienceDirect, and JSTOR with specific keywords from 2010 to 2023. We included trusted studies, clinical trials, and reviews. We gathered data on nutrition, health benefits, farming practices, and economic analysis. We checked the quality of these studies using standard methods to ensure they are reliable and accurate.


Nutritional Composition

  • Fatty Acid Profile

    Sacha Inchi oil is well-known for having lots of healthy polyunsaturated fats, especially alpha-linolenic acid (ALA, ω-3) and linoleic acid (LA, ω-6). The typical fat breakdown is:

    • ALA (ω-3): 48-60%

    • LA (ω-6): 15-20%

    • OA (ω-9): 15-20%

    • Palmitic Acid: 10-15%

    This good balance of omega-3 and omega-6 fats helps keep the heart healthy, lowers inflammation, and supports overall body functions.

    Comparison with Other Oilseeds

    Compared to flaxseed and chia seeds, Sacha Inchi has more ALA. Flaxseed oil has about 50-60% ALA, like Sacha Inchi, but Sacha Inchi has more ALA than chia seeds, which have around 30-35%. Also, Sacha Inchi has a better balance of omega-6 to omega-3 fats, helping to reduce inflammation in the body.

  • Protein Content

    Sacha Inchi seeds have about 30-35% protein, making them a great plant-based protein source. They are high in essential amino acids like lysine, which many other plant proteins lack. This makes Sacha Inchi protein very useful for vegetarian and vegan diets, helping to repair and grow muscles.

    Comparison with Other Plant Proteins

    Sacha Inchi has a bit less protein than soybeans (36-40%) but has a better mix of amino acids, especially lysine. This makes Sacha Inchi a more complete protein source for plant-based diets.

  • Vitamins and Minerals

    Sacha Inchi is a great source of vitamin E (tocopherols and tocotrienols), which are powerful antioxidants. The seeds also provide important minerals like magnesium, potassium, and calcium, essential for strong bones, muscle health, and maintaining electrolyte balance.

    Comparison with Other Nutrient-Dense Seeds

    Compared to pumpkin seeds, which are high in magnesium and zinc, Sacha Inchi provides a wider range of vitamins, especially vitamin E. This makes Sacha Inchi a great source of both essential minerals and antioxidants.

  • Antioxidants

    Sacha Inchi oil has antioxidants like flavonoids and phenolic compounds that make it more stable and healthier. These antioxidants fight free radicals, reducing oxidative stress and lowering the chance of long-term diseases.

    Comparison with Other Antioxidant-Rich Foods

    Although blueberries and dark chocolate are famous for their antioxidants, Sacha Inchi offers a special mix of antioxidants in a nutrient-packed seed form, making it easier to add to your daily diet for continuous antioxidant benefits.


Health Benefits

  • Cardiovascular Health

    Sacha Inchi oil is rich in omega-3 fats, which help lower triglycerides, reduce blood pressure, and decrease the risk of atherosclerosis (hardening of the arteries). Eating Sacha Inchi regularly can improve cholesterol levels and heart health, making it a great addition to diets that aim to prevent heart diseases.

Agricultural Practices

  • Cultivation Requirements

    Sacha Inchi grows best in tropical areas with regular rainfall and rich, well-drained soil. It prefers soil with a pH between 5.5 and 7.0. While it can handle some drought, Sacha Inchi grows better with steady moisture, making it suitable for places with different rain patterns.

  • Propagation and Harvesting

    Sacha Inchi is usually grown from seeds, which need to be scratched or treated (scarification) to help them sprout. The plants become ready to harvest in 6-8 months. Harvesting is done by hand to collect the seed pods. Using effective harvesting methods is important to reduce seed loss and get high-quality crops.

  • Pest and Disease Management

    Although Sacha Inchi is generally resistant to pests and diseases, it can still face issues like fungal infections and insect attacks. Using integrated pest management (IPM) methods, such as rotating crops, using natural predators, and minimizing pesticide use, helps keep the plants healthy and prevents financial losses.

    Related Studies

  • Sustainable Practices

    Using eco-friendly farming methods like rotating crops, using organic fertilizers, and limiting pesticide use is vital for keeping the soil healthy and the environment balanced. Sustainable farming boosts crop production and ensures that Sacha Inchi can be grown successfully for many years.
