At this point, the oil extraction rate is mass transfer controlled. The oil diffusion rate from the interior to the surface of the particles is low compared to the initial mass transfer rate.
Supercritical carbon dioxide extraction of apricot kernel oil
The purpose of this research was to determine the solubility of apricot (Prunus armeniaca L.) oil in supercritical carbon dioxide (SC-CO 2 ), effects of parameters (particle size, solvent flow rate,
Feb 1, 2001A simple mathematical model to characterize the supercritical extraction process has been proposed in this paper. This model is primarily based on two mass transfer mechanisms:
- How is apricot kernel oil extracted?
- Gupta and Sharma (2009a) worked on apricot kernels oil extraction by using table oil expeller, baby oil expeller, and oil press (power Ghani) and reported oil yield as 37.5–38.5%, 31.5–32.0%, and 28.5–29.0%, respectively.
- How apricots are processed?
- The processing of apricots results in by-products (i.e., kernel or seeds), which contain valuable biological compounds. Kernels are rich in fiber, lipid, and protein. Due to this chemical richness, kernels are processed into different products such as flour, oil, biodiesel, bio-oil, char, and protein isolates.
- Does supercritical carbon dioxide affect apricot kernel oil recovery?
- Özkal et al. (2005) worked on the application of supercritical carbon dioxide for apricot kernel oil extraction for higher oil recovery. They reported parameters viz. solvent flow rate, temperature, pressure, and co-solvent concentration produce a significant effect on oil recovery.
- Can apricot be extracted by solid-phase microextraction method?
- According to the authors, the most characteristic aroma of apricot could be obtained by solid-phase microextraction method due to the highest number of extracted aroma compounds. Such component groups as esters, aldehydes, and alcohols could be extracted using this method. In contrast, they could not be extracted by any other tested methods.
- What are the by-products of apricot processing?
- Figure 22.1 summarizes various by-products generated from apricot processing. An important by-product of apricot processing is the kernel or seed. The proximate composition of seeds varies according to cultivar, location, and harvesting time.
- Why is apricot kernel a good source of oil?
- Oil from the apricot kernel is valued by the richness of unsaturated fatty acids, the high proportion of oleic acids, phenols, and tocopherol content. Oil yield with quality from apricot kernel varies with region, variety, and adopted method of oil extraction.
