• How is edible oil extracted?
  • In a typical edible oil processing plant oil is extracted from the seed first using mechanical extraction (expeller press) followed by chemical extraction (hexane extraction). By using both methods less than 1% of the oil is left in the meal that is produced. The majority of this meal is sold for use in animal feed rations.
  • What is edible oil standardization?
  • The key word is standardization. It is the aim of standardization of edible oils to define grades for the final products, specify purity and quality parameters, establish requirements for labeling, and list adequate methods of analysis.
  • What are the international standards for edible oil?
  • International policies in the edible oil sector have evolved, and the levels of standardization at the international level are found. Codex Alimentarius standards are voluntary but serve as a reference in the settlement of international trade disputes. In Europe and USA, the regulation on the marketing and analysis of oils is harmonized.
  • Can edible oil-based nanomaterials be used in industrial applications?
  • Before realizing the industrial application of vegetable oils, the abovementioned problems need to be solved in a timely and effective manner. In addition, the preparation of edible oil-based nanomaterials and their synergy with other active ingredients are a focus of future research.
  • How much oil can be extracted from vegetable oil crops?
  • Table 1. Extraction of vegetable edible oils from oil crops. Maximum oil extraction yield = 55.47%. T = 60¨C65 ¡ãC, Solvent = n-hexane.
  • Which methods are used in vegetable oil extraction?
  • From the preceding analysis, it is observed that recent research on vegetable oil extractions has been focused more on the assisted methods (microwave and ultrasound) and supercritical fluid extraction compared to the conventional solvent and mechanical extraction methods.
