Foaming properties and olfactory profile of fermented chickpea aquafaba and its application in vegan chocolate mousse.

Aquafaba, the cooking water of chickpeas and other pulses, is used as a vegan egg white substitute because of its favorable technofunctional properties. Nonetheless, its application is often restricted by a "beany" flavor and poor foaming properties compared to egg white. To overcome these limitations, aquafaba was fermented with two edible basidiomycetes.

Improved Generation, Physicochemical Characteristics, and Food Application Studies of a Red Colorant Obtained from Oxidative Coupling of Chlorogenic Acid and Tryptophan.

Due to a widespread consumer reluctance toward synthetic food dyes, the interest in natural compounds from plants has increased. This study aimed to optimize the oxidation process between chlorogenic acid (CQA) and tryptophan (Trp) using sodium periodate (NaIO) to obtain a red-colored pigment. The impact of temperature and different ratios of Trp to NaIO on the reaction progress was investigated.

Fatty Acid Composition, Tocopherols, Volatile Compounds, and Sensory Evaluation of Low Morphine Yielding Varieties of Poppy ( L.) Seeds and Oils.

Low morphine yielding winter ('Zeno Morphex') and summer ('Viola', 'Mieszko', 'Borowski') poppy varieties were investigated for their chemical composition and sensory properties. The oil content of the 13 seed samples as well as that of fatty acids, tocopherols, and volatile compounds in the respective oils were determined, and the sensory profiles of the seeds and oils were established. Linoleic acid made up 70.

Characterization of phenolic and other polar compounds in peel and flesh of pink guava (Psidium guajava L. cv. 'Criolla') by ultra-high performance liquid chromatography with diode array and mass spectrometric detection.

Pink guava (Psidium guajava L.) is a highly consumed fruit in tropical countries. Despite of interesting research on health effects of this fruit, investigations into the profile of secondary plant metabolites are scarce.

Growth suppression of Fusarium culmorum, Fusarium poae and Fusarium graminearum by 5-n-alk(en)ylresorcinols from wheat and rye bran.

Alk(en)ylresorcinols (AR), a class of phenolic lipids, are regarded as antifungal compounds showing high potential for the use in plant protection, especially against Fusarium head blight (FHB). In view of the very limited knowledge of the activity of single AR against Fusarium species, the antifungal effect of crude extracts, fractions and isolated homologues from wheat and rye bran was determined. It was shown that the saturated AR are the active compounds in the extracts, whereas the presence of unsaturated molecules leads to an antagonistic effect.

Differentiation of Brazilian Peppertree (Schinus terebinthifolius Raddi) and Peruvian Peppertree (Schinus molle L.) Fruits by UHPLC-UV-MS Analysis of Their Anthocyanin and Biflavonoid Profiles.

The objectives of this work were to determine the phenolic profile of Schinus terebinthifolius and Schinus molle fruits and to develop a reliable method for the differentiation of these two similar spices both known as pink pepper. Anthocyanins, biflavonoids and gallotannins, some of which are reported for the first time in these species, were identified by UHPLC-UV/vis-MS/MS. Consideration of the relative and absolute amounts of phenolics as well as indicator compounds from 18 samples revealed that the relative amounts of anthocyanins and biflavonoids are the most trustworthy parameters.

Carotenoid Profile, Antioxidant Capacity, and Chromoplasts of Pink Guava (Psidium guajava L. Cv. 'Criolla') during Fruit Ripening.

Pigments of pericarp and pulp of pink guava (Psidium guajava L. cv. 'Criolla') were investigated to elucidate the profile and the accumulation of main carotenoids during four stages of fruit ripening by using HPLC-DAD and APCI-MS/MS analysis.

Pressurized liquid extraction of anthocyanins and biflavonoids from Schinus terebinthifolius Raddi: A multivariate optimization.

Response surface methodology was employed to investigate the effects of pressurized liquid extraction (PLE) parameters on the recovery of phenolic compounds (anthocyanins, biflavonoids) from Brazilian pepper (Schinus terebinthifolius Raddi) fruits. The effects of temperature, static time, and ethanol as well as acid concentration on the polyphenol yield were described well by quadratic models (p<0.0001).

Separation and isolation of saturated and unsaturated 5-n-alk(en)ylresorcinols from rye bran.

Alkylresorcinols (AR) are a class of phenolic lipids which are found in a number of plants and microorganisms and which are associated with various biological activities. In view of the very limited availability of reference compounds, we developed a process for the isolation of AR from rye bran. For this purpose, a crude extract was subjected to deep bed filtration at -80 °C, whereby the crystallized saturated AR were separated from the unsaturated homologues.

Evidence for the Formation of Benzacridine Derivatives in Alkaline-Treated Sunflower Meal and Model Solutions.

Sunflower extraction meal (SEM) is an economically interesting protein source. During alkaline extraction of proteins, the presence of chlorogenic acid (CQA) in the meal gives rise to the formation of o-quinones. Reactions with nucleophiles present in proteins can lead to green discoloration.

Characterization of phenolic compounds in Brazilian pepper (Schinus terebinthifolius Raddi) exocarp.

The objective of this study was to characterize the phenolic composition of Brazilian pepper (Schinus terebinthifolius Raddi) exocarp extract. Using UHPLC-DAD-MS/MS analysis, four anthocyanins, three biflavonoids, gallic acid, and two types of hydrolyzable tannins (galloyl glucoses, galloyl shikimic acids) were tentatively identified. The structure of the so far unknown 7-O-methylpelargonidin 3-O-β-D-galactopyranoside was elucidated by 2D NMR.
