Biodiesel from Siberian apricot (Prunus sibirica L.) seed kernel oil
In this paper, Siberian apricot (Prunus sibirica L.) seed kernel oil was investigated for the first time as a promising non-conventional feedstock for preparation of biodiesel. Siberian apricot seed kernel has high oil content (50.18±3.92%), and the oil has low acid value (0.46mg g-1) and low water content (0.17%). The fatty acid composition of the […]
Brief postharvest exposure to pulsed light stimulates coloration and anthocyanin accumulation in fig fruit (Ficus carica L.).
The poor coloration of nethouse-grown fig fruit (Ficus carica L.) due to insufficient sunlight stimulation reduces marketability and health value. This study examined the possibility of improving the color of harvested 'Brown Turkey' figs through the use of pulsed light (PL) emitted by a high-energy xenon flash lamp. The exposure of poorly colored figs to […]
Development of a Buccal tablets for Curcumin using Anacardium occidentale Gum
The objective of the present investigation was to develop uni-directional, bilayered, buccoadhesive tablets of curcumin using a natural buccoadhesive polymer cashew nut tree gum along with ethyl cellulose as an impermeable backing layer. A batch prepared with 20% polymer concentration, 0.1% penetration enhancer, 40 mg backing layer, compressed at 2 tons/cm2 for 10 sec was […]
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 […]
Defatted cashew nut shell starch as renewable polymeric material: Isolation and characterization
Starch attracts public attention as a replacement of fossil fuel in polymer industries because it is renewable; biodegradable and nontoxic. In this study; the isolation of starch from defatted cashew nut shell (CNS) using wet milling was reported. A product that contains 85.01 wt.% starch was recovered from the defatted CNS. Various analyses were performed […]
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 […]
Use of date (Phoenix dactylifera L.) blanching water for reconstituting milk powder: yogurt manufacture
The processing of dates yields high volumes of blanching water. The use of such blanching water for reconstituting skim milk powder to produce low fat yogurt was studied. Physicochemical properties and antioxidant activity of two date cultivars (Medjoul and Confitera) blanching water were determined. Quality characteristics of yogurts (control; Medjoul and Confitera) were evaluated during […]
Interactions between vegetative and generative growth and between crop generations in fig tree (Ficus carica L.)
Yield in fruit trees strongly depends on the balance between vegetative growth and fruiting. This balance is particularly complex in fig tree (Ficus carica L.); in which two generations of figs (Breba and Main crop) develop along an annual shoot and compete with two consecutive growth seasons. For better understanding the interaction between vegetative growth […]
Effect of pollination intensity; frequency and pollen source on fig (Ficus carica L.) productivity and fruit quality
Yield and fruit quality in fig (Ficus carica L.) are highly dependent on cultural practices especially caprification (pollination). However; this technique remains not well controlled in Tunisia. This study was conducted during two successive years; 2009 and 2010; to investigate different pollination conditions; i.e. number of caprifigs and repetitions of caprification on fruiting of two […]
