Subcritical low temperature extraction technology and its application in extracting seed oils

Abstract

Seed oils are of increasing interest to research and industry because they are a renewable, relatively inexpensive resource, they have valuable mechanical and chemical properties, and they have considerable nutritional benefits. Besides the traditional oil extraction methods, subcritical low temperature extraction as an innovative, clean, and environmentally friendly technology has attracted considerable attention recently. This new technique has many excellent properties, such as low temperature and pressure, short time, better selectivity, environmental compatibility, process simplicity, and the elimination of residual solvent. This review describes the technique of

Nutritional composition, health-promoting effects, bioavailability, and encapsulation of tree peony seed oil: a review

“…This can produce harmful substances such as polycyclic aromatic hydrocarbons and trans -fatty acids, which can negatively impact the quality and inherent flavor of oils and fats. 84 Additionally, the presence of residual organic solvents can pose potential health hazards.…”

“…41 Subcritical extraction of TPSO surpasses solvent extraction and pressing methods in terms of oil yield, quality, and appearance. 84 Lastly, aqueous enzymatic extraction is a desirable alternative as it eliminates the need for n -hexane, which poses health, safety, and environmental concerns. Consequently, the resulting product is free from solvents and boasts a remarkable nutritional value.…”

Development of Agarwood Oil Research and Benefit: Bibliometric Analysis

“…The production of agarwood oil involves various extraction methods, with hydrodistillation being the preferred method for determining the essential oil content of agarwood [8]. Agarwood oil is widely used in cosmetic, perfume, and medicinal applications due to its unique characteristics and high medicinal value (Wang et al, 2021). Moreover, agarwood oil has been explored for its potential as an antifungal agent and for its application in edible films and hydrosol-based drinks [9], [10].…”

Temperature prediction of subcritical extraction vessel based on Informer

“…The industrialization of low-temperature subcritical extraction technology for oil and fat extraction began in China in the early 1990s. It has many advantages in extracting the fat-soluble components of natural products, such as high extraction activity, low operating cost and stable product quality [1][2][3] . Extraction temperature is an important indicator of lowtemperature subcritical extraction technology, and the temperature in the vessel during extraction is generally maintained at 30-45 °C.…”
