Marketed by some as the best part of waking up, coffee is a crucial ingredient in the morning routines of many people around the world. While most of the global coffee supply ends up ground and brewed to create the classic breakfast beverage, the unique properties of the bean and the oil it contains give…
When the outer layer of brown rice, or bran, is removed to make white rice, it sets off a ticking time bomb for processors. The milling process activates an enzyme in the bran that quickly breaks down lipids—destroying the valuable fat that could otherwise be extracted as rice bran oil. Moreover, raw rice bran has…
As the world’s most abundant oilseed crop, soybeans supply the most common source of vegetable protein in animal feeds and human foods. Although soy’s prime purpose is to produce meal for animal feed, the meal remaining after oil extraction can be further processed into other useful ingredients. In the form of texturized soy protein (TSP),…
It’s no wonder why the source of cocoa beans, the cacao tree, was named “food of the gods” (Theobroma). The distinctively chocolatey flavor of cocoa products has been a favorite of countless civilizations throughout time—satisfying cravings both bitter and sweet, while supplying a bounty of beneficial qualities beyond food. However, many overlook the complexities of…
Although large-scale soybean processors dominate the commodity vegetable oil markets, these solvent extraction plants can’t produce organic products because of the hazardous chemicals they use. So, while small-scale mechanical oil mills may not be able to compete in terms of overall production volume or oil recovery rates, they can differentiate themselves by specializing in organic…

Sticks and stones may not break your bones, but they can certainly wreak havoc on an oil seed processing plant. No matter what material you process or which market you serve, the quality of the seeds you crush determines the quality of the oil and other byproducts. Foreign objects can impede this process and degrade…
As the primary source of protein in most animal feed formulations, soybean is highly valued for its unique amino acid profile as a low-cost nutrient supply. Unfortunately, as nutritional as soybean can be, it also contains some anti-nutritional factors that can harm animals and humans. The most problematic enzyme, soybean trypsin inhibitor, must be properly…
The ultimate goal of pressing oilseeds is to separate the oil from the solid seed material. Even in the most efficient processing plants, the oil leaving the press could still contain up to 10-20% solids by weight, which impacts the final product quality. Processors have a few options to remove these remaining particles and clarify…
