Overview
Peanuts (Arachis hypogaea) are a nutrient-dense legume cultivated worldwide for their edible seeds. Despite being classified as a nut in culinary contexts, they are botanically legumes. Peanuts grow underground, unlike tree nuts, and are a staple in diets across Asia, Africa, and the Americas. Globally, China, India, and the U.S. are the top producers. Peanuts are valued for their high protein content (25–30%) and healthy fats, making them a cost-effective source of nutrition. They are consumed raw, roasted, or processed into products like peanut butter and oil.
Product Features
Peanuts are rich in monounsaturated and polyunsaturated fats, which support heart health. They also provide vitamin E, B vitamins (especially niacin), and minerals such as magnesium, phosphorus, and zinc. Their antioxidant content, including resveratrol, contributes to anti-inflammatory benefits. Peanuts have a long shelf life when stored properly, thanks to their low moisture content. However, they are prone to aflatoxin contamination if exposed to humidity, requiring strict quality control in storage and transportation.
Main Uses
Peanuts are versatile in culinary applications. They are eaten as snacks, used in confectionery (e.g., peanut brittle), and pressed for oil, which has a high smoke point ideal for frying. Peanut butter is a popular spread, while peanut flour is used in gluten-free baking. Industrially, peanut oil is employed in cosmetics and lubricants. The protein-rich meal leftover from oil extraction serves as animal feed. In some cultures, peanuts are fermented into sauces or incorporated into savory dishes like satay and kare-kare.
Culture and Development
Peanuts originated in South America, with archaeological evidence dating back to 7,600 years in Peru. Spanish and Portuguese traders introduced them to Africa and Asia, where they became dietary staples. The U.S. popularized peanut butter in the early 20th century, driven by innovators like George Washington Carver. Today, peanuts are a symbol of sustainability due to their nitrogen-fixing properties, which improve soil health. China leads global production, accounting for nearly 40% of the supply, followed by India and Nigeria.
B2B Procurement Guide
For bulk procurement, prioritize suppliers with certifications (e.g., ISO, HACCP) to ensure quality and safety. Key metrics include moisture content (≤10%), aflatoxin levels (≤20 ppb), and kernel size uniformity. Contract farming or direct sourcing from cooperatives can reduce costs. Shipping and storage require climate-controlled environments to prevent mold growth. Prices fluctuate based on crop yields and global demand—monitor markets in Q3/Q4, when harvests peak. Consider processed forms (e.g., blanched, oil) for longer shelf life in export markets.
