Polyphasic approach to the identification of Aspergillus section Flavi isolated from Brazil nuts
The aim of this study was to use a polyphasic approach to identify Aspergillus section Flavi isolated from Brazil nuts collected in the Amazon forest: investigation of macro- and microscopic morphology, production of extrolites, heat-resistance fungi, and sequencing of DNA regions. The following Aspergillus section Flavi species were identified: Aspergillus flavus (75.5%), Aspergillus nomius (22.3%), […]
Valorization of date palm (Phoenix dactylifera) fruit processing by-products and wastes using bioprocess technology – Review
The date palm Phoenix dactylifera has played an important role in the day-to-day life of the people for the last 7000 years. Today worldwide production, utilization and industrialization of dates are continuously increasing since date fruits have earned great importance in human nutrition owing to their rich content of essential nutrients. Tons of date palm […]
Date palm by-products as a new ingredient for the meat industry: Application to a pork liver pâté
Date palm is an interesting source of bioactive compounds that could be used as ingredient in meat products; thus a campagne type pork liver pâté was elaborated using fresh date by-products (0, 5, 10 and 15%). Physicochemical properties, pigment and lipid oxidation, residual nitrite level, texture and sensory analysis during 4 days after the elaboration […]
Effect of pollen source on quantitative and qualitative characteristics of dried figs (Ficus carica L.) cvs ‘Payves’ and ‘Sabz’ in Kazerun – Iran
In dried fig production, caprification (pollination) is very important to obtain economical yield. The selection of pollen source with good quality and quantity of pollen is an essential practice in fig orchards. This study was conducted in Kazerun region, Iran, to investigate the effect of pollen source on quantitative and qualitative characteristics of dried figs […]
Berry components inhibit α-glucosidase in vitro: Synergies between acarbose and polyphenols from black currant and rowanberry
Polyphenol-rich extracts from certain berries inhibited α-glucosidase activity in vitro. The two most effective berry extracts, from black currant and rowanberry, inhibited α-glucosidase with IC50 values respectively of 20 and 30 μg GAE/ml and were as effective as the pharmaceutical inhibitor, acarbose. These berry extracts differed greatly in their polyphenol composition: black currant was dominated […]
Use of rapid screening methods for detecting drought tolerant cultivars of fig (Ficus carica L.)
A preliminary study was conducted to determine the effects of water stress on four fig cultivars (Ficus carica L., 'Deyme Ahvaz' (Deym), 'Sabz Estahban' (Sabz), 'Siah' and 'Shahanjir' (Shah)) plants, using reliable and easy to use methodology. Potted plants, growing under greenhouse conditions were subjected to drought by withholding irrigation for 14 days. Stressed plants […]
Carcass performance and meat mineral content in Balouchi lamb fed pistachio by-products
This experiment investigated the effect of pistachio by-products (PB) in the feed of weaned Balouchi lambs on their daily gain, carcass traits and on the levels of Ca, Zn, Fe and Cu of Longissimus dorsi muscle. Twenty eight male lambs were divided into four groups with 7 lambs each and fed separately for 90 days. […]
An eco-friendly method for short term preservation of skins/hides using Semecarpus anacardium nut extract
Preservation or curing of hides and skins is performed as the primary step of leather processing. Common salt is employed as the conventional agent for curing purpose. Use of salt enhances the pollution load of tannery effluent which becomes highly contaminated with increased total Dissolved Solids (TDS) and chlorides (Cl). To overcome this hurdle, researchers […]
Enzyme activity and biochemical changes of three date palm cultivars with different softening pattern during ripening
The physicochemical composition changes during palm ripening were studied. The activities of invertase and cell wall-modifying enzymes, namely pectin methylesterase (PME), β-galactosidase (β-Gal), endo-1,4-β-d-glucanase (EGase), and cellulase were monitored during growth and ripening of Shahani, Piaro and Deiry cultivars with different texture. Also we estimated the concentrations of six organic acids by HPLC .Reducing sugars, […]
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 […]
