Phosphatidylcholine (PC) represents the most abundant class, fol lowed by phosphatidylinositol (PI), phosphatidylglycerol (PG), and phosphatidic acid (PA). The total PL content is comparable to that of almonds and cashew nuts. In terms of PL structures, pumpkin seeds feature a higher abundance of C18:2-containing PL isomers, a preferential esterification of C18:1 and C18:2 at the sn-2 position as well as a predominant Δ9/Δ9,12 double bond locations for C18:1 and C18:2 respectively. This is the first systematic study on PLs of pumpkin seeds to our knowledge. Our findings add further evi dence on the potential value of pumpkin seeds as a functional food or as a source material for making plant-based drink.

abundant phosphatidylinositol. Fewer plasmalogens but more lyso-glycerolphospholipids were found in ultra-high-temperature (UHT) sterilized milk than in pasteurized milk, and higher pro portions of lyso-glycerolphospholipid/total phospholipid were observed in both cream and skimmed/semi-skimmed milk than whole milk, indicating that UHT and skimming processes improve glycerolphospholipid degradation and phospholipid nutrition loss. Meanwhile, more diacyl-glycerolphospholipids and less of their degradation products make yogurt a better phospholipid resource than whole milk. Comprehensive analysis of phospholipids in pumpkin (Cucurbita maxima) seeds: Comparison with cashew nuts and almonds Wang, W., et al. , Journal of Food Composition and Analysis , 135, 106602, 2024. https://doi.org/10.1016/j.jfca.2024.106602 Pumpkin (Cucurbita maxima) seeds have gained increas ing attention due to their high nutraceutical value; however, data regarding the phospholipid (PL) profile of this oily seed are scarce. Through the combination of RPLC-MS/MS, HILIC-MS, and Paternò-Büchi photochemical reaction, we comprehensively char acterized PLs in three accessions of pumpkin seeds. We iden tified a total of 183 PL molecular species across eight classes.
