Nut and seed butters: lipid component quality and its changes during storage

Popis výsledku v původním jazyce

Nowadays, pure nut and seed butters are a popular food category perceived as health-beneficial. However, only limited attention is paid to potentially toxic/antinutritional products of lipid oxidation. This study assessed lipid component quality and its changes in 40 different nut and seed butters (peanut; almond; hazelnut; walnut; cashew; sunflower, hemp, and pumpkin seed) available on the Czech market. Within the 7-month storage, acid values were stable or only slightly increasing except the walnut samples with up to 8× increase. Peroxide values varied depending not only on sample type, but also between individual samples; in general, cashew and hazelnut samples had the lowest peroxide values, while significant differences were found between peanut butters produced from high-oleic and standard peanut varieties. For a deeper insight into ongoing processes, triacylglycerol oxidation products were screened by supercritical fluid chromatography coupled to high-resolution tandem mass spectrometry (SFC-HRMS/MS). Moreover, fatty acid composition, determined by gas chromatography coupled to flame ionization detector (GC-FID), and TAG composition, profiled by SFC-HRMS/MS, were compared with the literature, and no adulteration by replacing/adding other than declared nuts/seeds was detected.
