• How is soybean oil extracted?
  • Two common soybean oil production processes are solvent extraction (chemical) and mechanical extraction using a screw press. The most conventional method is to extract oil by mechanical oil processing machines. The oil obtained from screw press, known as crude oil, usually undergoes a filtration process before being consumed as food.
  • Why do we need improved cultivars for vegetable oil extraction?
  • Limited land availability and growing demands for vegetable oils call for the development of improved cultivars for harnessing higher yields as well as more efficient oil extraction technologies to augment oil recovery from different oilseed crops without compromising with the oil quality.
  • Why is automatic soybean oil processing plant necessary?
  • Automatic soybean oil processing plant is necessary because of the low efficiency of the oil extracted by hand operated machines.
  • What is the difference between conventional oil extraction and mechanical pressing?
  • The traditional methods of oil extraction are exhaustive and have low efficacy, while conventional method of mechanical pressing is simple and involves low cost but considered as an inefficient method because of low oil recovery when compared with chemical extraction methods.
  • What are the eco-friendly methods for edible oil extraction?
  • New advanced eco-friendly techniques namely, enzyme-assisted extraction, microwave-assisted extraction, ultrasound-assisted extraction, and supercritical fluid extraction can easily overcome the shortcomings of the conventional methods and holds the potential to meet the ever-increasing demand of edible oils.
  • How vegetable oil is obtained from different matrices?
  • The vegetable oils are obtained from the oilseeds and also from other oil bearing parts of plants like fruits (mesocarp and/or stones), tubers, germs, sprouts, and so on. A host of methods are employed to obtain the oil from different matrices and each method has its own set of advantages and disadvantages.
