Overview
Raw cashew nuts are the seeds extracted from the cashew apple, the fruit of the tropical cashew tree. Unlike most nuts sold commercially, cashews are always sold shelled because their shells contain a toxic resin called urushiol, which must be carefully removed during processing. Cashew nuts are prized for their rich, buttery flavor and versatile culinary applications. They are a significant global agricultural commodity, with major production in Vietnam, India, Ivory Coast, and Brazil. The nuts undergo several processing steps including steaming, shelling, drying, and peeling before being suitable for consumption or further processing.
Product Features
Raw cashew nuts are characterized by their distinctive kidney shape and smooth, creamy texture. They have a mild, slightly sweet flavor that intensifies when roasted. Nutritionally, they are an excellent source of monounsaturated fats (about 75% of their fat content), protein (about 18% of weight), and important minerals including magnesium, zinc, and iron. The nuts have a relatively high oil content (about 47% by weight), which makes them valuable for both food and industrial applications. Their natural composition includes antioxidants like tocopherols and phenolic compounds. Properly processed raw cashews have a moisture content of about 5-7%, which is critical for shelf stability.
Main Uses
In culinary applications, raw cashew nuts serve as a base for numerous products. They are commonly used in vegan cuisine to create dairy alternatives like cashew milk, cheese, and cream due to their creamy texture when blended. The confectionery industry uses them in chocolates, nougats, and as toppings for desserts. Industrial applications include the production of cashew butter, which serves as a peanut butter alternative, and cashew oil used in cooking and cosmetic formulations. In many Asian cuisines, cashews are essential ingredients in curries and stir-fries. The nuts are also popular as a healthy snack, either raw or roasted, and often included in trail mixes and granola products.
Culture and Development
The cashew tree originated in northeastern Brazil, where indigenous tribes used both the nut and the cashew apple. Portuguese colonists introduced the tree to India and East Africa in the 16th century, primarily to combat soil erosion, but its commercial value was soon recognized. Today, India initially dominated global cashew processing, but Vietnam has become the world's largest exporter since the 1990s. The industry has faced challenges regarding labor conditions in processing facilities, leading to increased mechanization. Cashew production supports the economies of several developing nations, with the global market valued at over $6 billion annually.
B2B Procurement Guide
When procuring raw cashew nuts in bulk, buyers should consider several factors. Origin significantly affects quality and price - Vietnamese W320 grade is currently the global benchmark. Moisture content should be verified (ideally ≤7%) to prevent mold growth during storage and transportation. Processing method is crucial - steam or oil bath processing affects the final product quality. Buyers should request certificates for aflatoxin levels (should be <10 ppb), pesticide residues, and processing standards. Minimum order quantities typically range from 1-10 metric tons for wholesale purchases. Payment terms commonly involve 30-50% advance with balance against shipping documents.
