Peanuts 

Peanuts, though often grouped with tree nuts, belong to the legume family alongside soy and lupin. They hold a unique position in the global food industry due to their affordability, widespread availability, and distinct flavor. Their rich nutritional profile and versatility make them a popular ingredient in baking and confectionery, offering depth of taste and texture to various products.

Peanut Production and Nutritional Value

Peanuts originated in South America and are now cultivated worldwide, with India and China as the largest producers. Their global popularity has grown steadily since the 19th century, and they play an essential role in many cuisines. In Asia, peanuts are used in sauces and savory dishes, while in North America and Europe, they are commonly found in peanut butter, confectionery, biscuits, and coated chocolate products.

Nutritionally, peanuts are high in protein (25.4%) and fat (48.4%), making them a valuable energy source. Peanut oil, also known as groundnut oil, consists primarily of unsaturated fatty acids, with over 40% oleic acid, which has gained recognition for its health benefits. Its high heat stability makes it ideal for roasting peanuts and for use in food production. However, peanuts must be properly dried (to 7% moisture) after harvest to prevent spoilage and contamination by aflatoxins, a harmful toxin produced by certain molds.

Varieties, Quality Standards, and Allergy Concerns

There are four main types of peanuts:

• Spanish Peanuts – Small and round, ideal for confectionery and decoration.
• Runner Peanuts – Common in the U.S. and Africa, widely used for salted peanuts.
• Virginia Peanuts – Large in size, valued for their texture and appearance.
• Valencia Peanuts – Smooth and flavorful, often used in sauces and specialty foods.

Strict quality standards ensure safe peanut consumption. They must be free of insect damage, maintain the correct moisture content (7-8% unroasted, 1.5-2% roasted), and have a fresh, clean taste. Aflatoxin levels must remain below 10 ppb, and microbiological controls prevent bacterial contamination. Another major concern is peanut allergies, which can cause severe reactions, making labeling and cross-contamination prevention essential in bakeries.

Peanuts in Baking and Confectionery

Roasting is a critical step before incorporating peanuts into baked goods, as it enhances flavor and texture. However, oxidation occurs quickly after roasting, so peanuts should be used immediately or stored properly to prevent rancidity. Some key baking and confectionery applications include:

• Chocolate-coated peanuts for snacks and confectionery.
• Peanut shavings in pastry and cake decoration.
• Roasted peanuts in cookies and biscuits for added crunch.
• Coated roasted peanuts in candy bars.
• Peanut butter as a fat or shortening replacer in cookies and waffles.

To maintain quality, peanuts should remain dry in baked goods, as moisture negatively affects their flavor, giving them a heavy, earthy taste. This is particularly relevant when using peanuts in sponge cakes, peanut-covered pastries, or nut-based coatings.

Peanuts continue to be a staple ingredient in bakery products, offering a rich, nutty taste, a satisfying crunch, and functional benefits in confectionery. Whether whole, chopped, roasted, or in paste form, they add value to baked goods, making them a timeless favorite in the industry.
