Phytonutrients and potential health benefits of California almonds: a comprehensive analysis of bioactives

This study provides a comprehensive metabolomic and lipidomic analysis of various almond varieties (Monterey, Nonpareil, Independence) and their pasteurized and non-pasteurized forms, identifying 530 phytochemicals (metabolites and lipids), including 17 bioactive substances, six of which were previously unreported in almonds. Using LC-MS and advanced data processing techniques, we explored the impact of pasteurization on almond composition, revealing alterations in fatty acid profiles and increases in polyphenols and flavonoids. Pasteurization was found to enhance oxidative stability while affecting nutrient content, notably increasing the oleic/linolenic ratio. Consistent bioactive compounds such as Beta-Sitosterol and Isorhamnetin underscore the known health benefits of almonds, including cardiovascular and cognitive support. Overall, this research highlights the significant health-promoting properties of almonds and the influence of processing on their nutritional profile, suggesting their continued inclusion in health-conscious diets.
