Stereospecific Positional Distribution of Fatty Acids of Camellia (Camellia japonica L.) Seed Oil

Abstract

The stereospecific positional distribution of fatty acids of camellia seed oil (also called camellia oil) was determined. The camellia oil was mainly composed of neutral lipids (88.2%), and the oleic acid (86.3%) was found to be a major fatty acid of neutral lipids. In the glycolipids and phospholipids, the oleic acid was also found to be a major fatty acid at 62.5% and 54.2%, respectively. The oleic acid was distributed abundantly in all sn-1, 2, and 3 positions. It was found that the oleic acid was present more at sn-2 (93.6%) and 3 positions (94.7%), than at sn-1 position (66.0%). Practical Application: The information of stereospecific positional distribution of fatty acids in the camellia oil can be used for the development of the structured lipids for food, pharmaceutical, and medical purposes.

Production of 1, 3-dioleoyl-2-palmitoyl glycerol as a human milk fat substitute using enzymatic interesterification of natural fats and oils

“…The fatty acid compositions of the fats and oils tested were all consistent with reported values (10,16). The oleic acid contents in camellia oil and chufa oil were 81.6 (by chromatogram area) and 69.7%, respectively.…”

“…Camellia oil was the most efficient oleic acid source for OPO production with both palm oil and lard. The oleic acid content at the sn-1 and 3 positions in camellia oil was 80.4% (10). Values for olive oil and chufa oil were 72 and 60.8%, respectively (9,24).…”

“…Preparation of concentrated reaction substrates, however, increases the processing cost. Camellia oil and chufa oil (also called earth almond oil) are known to contain large amounts of oleic acid and can be used as oleic acid sources, in addition to olive oil (9,10). The objectives of this study were 1) to determine reaction yields of OPO when non-preprocessed natural fats and oils were used, and 2) to compare reaction yields using novel oleic acid sources of camellia oil and chufa oil rather than the conventional source of olive oil.…”

Physiochemical characteristics, fatty acid profile and tocopherol composition of the oil from <em>Camellia oleifera</em> Abel cultivated in Henan, China

“…As a comparison, the oleic acid in the sn-1, 2, and 3 positions of C. japonica L. oil were 66.0%, 93.6% and 94.7%, respectively (Noh and Yoon, 2012). For other high-oleic acid vegetable oils, such as Chufa tuber oil, the major fatty acid composition of the oil was 15.4% palmitic, 65.5% oleic, and 16.2% linoleic, while the major fatty acid composition on its sn-2 position was 75.1% oleic and 23.1% linoleic (Kim et al, 2007).…”

Determination of benzo[a]pyrene in camellia oil via vortex-assisted extraction using the UPLC-FLD method

“…Camellia oil contains rich unsaturated fatty acids and antioxidative substances (9), similar to olive oil. Many studies have shown that camellia oil is beneficial to human health; moreover, it is increasingly favored by East Asian consumers (10).…”
