“…However, given that MD has been here modeled as batch conventional, some of previous developments in batch distillation could be applied to improve the model (remaining algebraic). Zamar et al (2005) propose a short cut model for batch where mass balances are solved based on the relative volatilities, distributing the non key components using simple algebraic equations. A multi component formulation would improve the present binary assumption.…”

“…antioxidants are Phenolic Compounds (PC) that are divided into different groups, according to their basic structure, (Zamar et al, 2005). These perform various physiological functions and are involved in the growth, reproduction and defence of plants against various pathogens, (Hosni et al, 2013).…”

The (Zingiber officinale) is a plant of the zingiberáceas family, its rhizome is widely used in gastronomy for its pungent aroma and flavor. Essential oils (EO) are natural compounds; they have 25 to 70 components with different concentrations. Α-Zingiberene and α-Felandrene are the main components with volumes between 20% and 70%. For the extraction of the AE samples from 10 Colombian geographical locations were used, obtained by microwave radiated hydrodistillation (MWHD) and stored at 4°C in amber vials. 50 µL of EA and 1.0 µL of (n-tetradecane) internal standard were dissolved in dichloromethane to a final volume of 1.0 mL. The EO components were performed on a triple quadruple mass detector gas chromatograph (BRUKER 450GC-320). For its antioxidant activity (AA) the methodology of Prior for DPPH* and ABTS+ was used. The extractions showed a yield between 0.053 and 0.109 percent; and 300 g of sample at 700 watts and 40 minutes of process were used. The chromatographic profile showed 43 components referring to ketones, alcohols, cyclic ethers, aldehydes and 23 hydrocarbons, with α-Zingiberene being the majority, considered as a molecular marker of this EO. The AA presents significant differences between the samples evaluated for the localities studied.

“…As the development of a simulation code is a time con suming task, bath for setting up the problem and for solving it, Zamar et al (2005) recommended the use of a simplified model even if it was less accurate. It is also possible to use commercial simulators.…”
