Bioactivity and chemical composition of blackcurrant (Ribes nigrum) cultivars with and without pesticide treatment
Eleven blackcurrant cultivars grown with pesticide (PT) and without pesticide treatment (PF) were evaluated to compare the differences in plant growth and physical condition; total anthocyanin content; ascorbic acid content; total antioxidant capacity; effect on prostaglandin E2 (PGE2) production and anticancer cell proliferation activities. Results showed that the yield and growth of PT blackcurrants were […]
Chemical and Structural Characterisation of Almond Oil Bodies and Bovine Milk Fat Globules
Lipids in almonds are present as oil bodies in the nut. These oil bodies are surrounded by a membrane of proteins and phospholipids and are a delivery vehicle of energy in the form of triglycerides; similarly to the more studied bovine milk fat globule membrane. Chemical; physical and microscopic analyses revealed major differences in the […]
Profiling of bioactive compounds in cultivars of Runner and Valencia peanut market-types using liquid chromatography/APCI mass spectrometry
Peanuts are classified into four market-types (Runners; Spanish; Virginia and Valencia) Studies on their phytochemical composition have focused mainly on market-types other than Valencia. The objectives of this study are to evaluate the phytochemical composition of cultivars of Valencia and Runner market-types. Extracts of twenty-five peanut cultivars of Runner and Valencia market-types were analyzed using […]
Analysis of roasted and unroasted Pistacia terebinthus volatiles using direct thermal desorption-GCxGC-TOF/MS
The objective of this study was to determine the effects of roasting time on volatile components of Pistacia terebinthus L.; a fruit growing wild in Turkey. The whole fruit samples were pan roasted for 0; 5; 10; 15; 20 and 25 min at 200 °C. Volatile compounds were isolated and identified using the direct thermal […]
Phenolic compound content of fresh and dried figs (Ficus carica L.)
Eighteen fig cultivars commonly grown in the south-eastern Spain were collected in two crops (spring and summer) and their polyphenolic profile was determined. Fruit from the first crop generally showed higher phenolic values than those from the second. Higher concentrations of total phenolics were found in skin than in flesh. LC-UV-DAD/ESI-MSn analysis of the figs […]
Antioxidative potential of cashew phenolics in food and biological model systems as affected by roasting
The effect of different roasting conditions on antioxidant capacity of phenolics of cashew nuts and their testa was evaluated using several food and biological model systems. Total phenolic content (TPC) of cashew extracts were determined and accelerated oxidative stability of stripped corn oil in the presence of cashew extracts evaluated. In addition; the antioxidant activity […]
Catechin and epicatechin in testa and their association with bioactive compounds in kernels of cashew nut (Anacardium occidentale L.)
Catechins in testa and bioactive compounds in testa-free and testa-containing kernels of cashew nuts were analyzed. The cashew nut testa contained (+)-catechin and (-)-epicatechin with concentrations of 5.70 and 4.46 g per kg DM; respectively. Testa-containing kernels revealed significantly higher levels of Ã-carotene (218 vs. 89.6 µg/kg DM); lutein (525 vs. 292 µg/kg DM); and […]
Chemical and aroma volatile compositions of date palm (Phoenix dactylifera L.) fruits at three maturation stages
Abstract: The effect of maturity stage on the physicochemical composition and volatile components of date palm fruits (Phoenix dactylifera L.) was investigated at three different stages. Total sugars; pH; proteins and ash increased up to the full-ripe stage of all date types. On the contrary; weight; moisture and total lipids decreased across the same period. […]
Enzymatic Treatment of Peanut Kernels to Reduce Allergen Levels.
Abstract: This study investigated the use of enzymatic treatment to reduce peanut allergens in peanut kernels as affect by processing conditions. Two major peanut allergens; Ara h 1 and Ara h 2; were used as indicators of process effectiveness. Enzymatic treatment effectively reduced Ara h 1 and Ara h 2 in roasted peanut kernels by […]
Pinolenic acid inhibits human breast cancer MDA-MB-231 cell metastasis in vitro
Pinolenic acid (PNA); a naturally-occurring polyunsaturated fatty acid (PUFA); is found mainly in pine seeds. Although many studies have demonstrated beneficial effects of pine seed oil; there are no reports of the biological effects of PNA on cancer metastasis. The objective of this study was to investigate the effect of PNA on human breast cancer […]
