Believe It or ‘Nut’: Why It Is Time to Set the Record Straight on Nut Protein Quality: Pistachio (Pistacia vera L.) Focus

There are growing public health movements to transition towards diets that are plant-based. However, confusion exists with concerns that plant-based proteins (including nuts) may be inferior with respect to protein quality. The present publication evaluates the evolution of protein quality concepts and explains the protein science related to pistachios. Pistachio nuts are a plant-based complete […]

Determination of ochratoxins in nuts and grain samples by in-tube solid-phase microextraction coupled with liquid chromatography-mass spectrometry.

A simple and sensitive method for the determination of ochratoxins A and B in nuts and grain samples was developed using an automated in-tube solid-phase microextraction (SPME) coupled with liquid chromatography-mass spectrometry (LC-MS). Ochratoxins were separated within 5 min by high-performance liquid chromatography using an Inertsil ODS-3 column with 5 mM anmonium acetate/acetonitrile (65/35 v/v) […]

Influence of light on food relevant fungi with emphasis on ochratoxin producing species

The influence of light of varying wavelength on growth and ochratoxin A biosynthesis of Aspergillus carbonarius; A. niger; A. steynii and on Penicillium nordicum and P. verrucosum was analysed. For comparison the influence of light on various other food relevant fungi; including citrinin producers; was also tested. Generally the Aspergilli seem to be more resistant […]
