Extraction of phenolic compounds and production of biomethane from strawberry and raspberry extrudates
(Elsevier, 2019)
This study proposes a biorefinery approach system to treat two berry extrudates generated by the berry-tasted products industry. The berry extrudates studied were strawberry extrudate (SE1 and SE2) and raspberry extrudate ...

Online monitoring of electrical conductivity of wine induced by ultrasound
(Taylor & Francis, 2016)
We assessed the effects of ultrasonic frequency, power, temperature and exposure time on the electric conductivity (EC) of wine to evaluate the feasibility of the online EC monitoring as an indicator to reflect the changes ...

Cetane number prediction of waste cooking oil-derived biodiesel prior to transesterification reaction using near infrared spectroscopy
(Elsevier, 2019-03)
Fifty waste cooking oils (WCOs) were transesterified with methanol (1:8 WCO:methanol molar ratio) at 60 °C for 60 min using NaOH as catalyst (1% wt.). Fatty acid methyl ester (FAME) composition of the resulting biodiesels was ...

Drying kinetics and effective water diffusivities in olive stone and olive-tree pruning
(Elsevier, 2019-03)
Drying kinetics of olive stone and olive-tree pruning, two important biomasses from olive culture, was experimentally assessed at six different temperatures (from 343 K to 393 K) and four sample thicknesses (from 15 to ...

Effect of ozone treatment on postharvest disease and quality of different citrus varieties at laboratory and at industrial facility
(Elsevier, 2018)
The effects of continuous and intermittent (simulating a day-night cycle) exposure to ozone enriched atmosphere (from 1.6 to 60 mg kg−1) at 5 °C for 28 d and subsequent shelf life at 20 °C for 15 d on six citrus varieties ...

Determination of the Acidity of Waste Cooking Oils by Near Infrared Spectroscopy
(MDPI, 2019)
Waste cooking oils (WCO) recycling companies usually have economic losses for buying WCO not suitable for biodiesel production, e.g., WCO with high free acidity (FA). For this reason, the determination of FA of WCO by ...

Effect of ultrasound on the interaction between (-)-epicatechin gallate and bovine serum albumin in a model wine
(Elsevier, 2017-07)
Ultrasound is considered as a potential novel technique for improving the quality of some wines. In this paper, a model wine firstly was constructed with the standards of ( )-epicatechin gallate (ECG) and bovine serum ...

Esterification of Free Fatty Acids with Glycerol within the Biodiesel Production Framework
(MDPI, 2019)
Companies in the field of the collection and treatment of waste cooking oils (WCO) for subsequent biodiesel production usually have to cope with high acidity oils, which cannot be directly transformed into fatty acid methyl ...
