DNA Barcoding Coupled With High-Resolution Melting Analysis for Nut Species and Walnut Milk Beverage Authentication.
Background: Walnut (Juglans regia L.) is one of the most widely cultivated nuts. Walnut milk beverage is very popular in China due to its nutritional value. However, adulterated walnut milk ingredients have been detected in the Chinese market. Peanut and soybean are sold at much lower prices than walnut and are reported as common adulterated species […]
Cultivation of black soldier fly larvae on almond byproducts: impacts of aeration and moisture on larvae growth and composition.
BACKGROUND: The increasing production of almonds worldwide has resulted in the significant generation of byproduct streams that require end uses. One potential use for byproducts is for cultivation of additional food sources including insects. Studies were performed to determine if black soldier fly larvae (Hermetia illucens L.) could be cultivated on almond byproducts (hulls and […]
Untargeted metabolomics with multivariate analysis to discriminate hazelnut (Corylus avellana L.) cultivars and their geographical origin.
BACKGROUND: In the present study, a metabolomic-based approach was used to discriminate different hazelnut cultivars as well as to trace their geographical origin. On this basis, ultra-high-pressure liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry (UHPLC-ESI/QTOF-MS), able to profile phenolic and sterolic compounds, was set up. RESULTS: Compounds identification was achieved thanks to accurate monoisotopic mass […]
Water‐soluble vitamin content of sun‐dried Corinthian raisins (Vitis vinifera L., var. Apyrena).
BACKGROUND: Corinthian raisins are dried vine products, representing approximately 3% of the world dried vine fruit production. The majority of Corinthian raisin production is of Greek origin. Studies on the B-group vitamin content of Corinthian raisins produced in Greece as well as on the effect of region and cultivation altitude on the B-group vitamin content […]
Functional and Sensory Properties of Pistachio Nuts as Affected by Cultivar.
BACKGROUND: Modern agriculture allows farmers to choose among different cultivars of the same fruit to fulfill their agronomic needs and consumers' demands; however, there are only few studies describing and comparing key functional and sensory properties of different pistachio cultivars. The main objective of this study was to compare eight pistachio cultivars by analyzing key […]
Comprehensive comparison of multiple quantitative near‐infrared spectroscopy models for Aspergillus flavus contamination detection in peanut.
BACKGROUND: Aspergillus flavus is a major pollutant in moldy peanuts, and it has a great influence on the taste of food. The secondary metabolites of Aspergillus flavus, including aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2), are highly toxic and can expose humans to high risk. Total molds count (TMC) is an important index to determine […]
Selected nutrients and anti‐nutrients in peanut cultivars harvested in Brazil.
BACKGROUND: There are more than 30 peanut cultivars registered in Brazil. However, there is no published data about the content of nutrients and anti-nutrients even in the most commercially important ones. Therefore, our objective was to characterize commercial peanut cultivars harvested in Brazil by determining proximate and fatty acid compositions and contents of selected minerals […]
Effects of a rotational UV‐C irradiation system and packaging on the shelf life of fresh pistachio.
BACKGROUND: In this study, fresh pistachio was exposed to UV-C irradiation (2.1 and 4.5 kJ m-2) in a rotating cylindrical system with seven germicidal UV-C lamps and immediately packed in perforated and non-perforated polyethylene terephthalate (PET). The fruit were evaluated for weight loss, total phenolic content, enzyme activities, color indices (L*, a*, b* and browning […]
Water-soluble vitamin content of sun-dried Corinthian raisins (Vitis vinifera L., var. Apyrena).
BACKGROUND: Corinthian raisins are dried vine products, representing approximately 3% of the world dried vine fruit production. The majority of Corinthian raisin production is of Greek origin. Studies on the B-group vitamin content of Corinthian raisins produced in Greece as well as on the effect of region and cultivation altitude on the B-group vitamin content […]
Elucidation of Hulling Induced Changes in the Aroma and Aroma-Active Compounds of cv. Uzun (Pistacia vera) pistachio.
BACKGROUND: The purpose of this study was to define the effects of the hulling process on the aroma and aroma-active composition of cv. Uzun pistachio. Four different hulling processes including wet, wet-dry, dry-dry, and brine were applied. In addition, SAFE, SDE, and P&T extraction methods were also tested to obtain the best representative aroma extract. […]
