However, significant differences in fruit oil content between <i>Pa</i> populations were observed. Further, FA composition varied significantly among species and between <i>Pa</i> populations. The main FAs were oleic (17%–73%), palmitic (17%–41%), linoleic (2%–32%), and stearic (3%–13%) acids. The mesocarp oil of some <i>Pa</i> palms contained a high amount (&gt;20%) of linoleic acid and a low amount of saturated FA (&lt;25%). A high variability of total tocochromanol (89, 122, and 145 mg/kg oil for <i>Pa</i>, <i>An</i>, and <i>Ad</i>, respectively) and total carotenoids (96, 42, and 157 mg/kg for <i>Pa</i>, <i>An</i>, and <i>Ad</i>, respectively) content was also found.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The fruits of the neglected Phytelepheae palms may represent a valuable source of lipids, including the essential FA linoleic acid and lipid-soluble vitamins, and help to diversify dietary lipid sources in Ecuadorian geographical areas where there is a high rate of saturated fat consumption.</p>\u0000 </section>\u0000 </div>","PeriodicalId":93795,"journal":{"name":"JSFA reports","volume":"3 11","pages":"549-560"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135804750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
