[EN] Lactic acid bacteria (LAB) have been shown to prevent the growth and activity of several postharvest pathogen fungi in fruit and vegetables because of their ability to produce antimicrobial metabolites. Edible coatings ...
[EN] The concept of function is a threshold concept in mathematics since it is essential for a deep understanding of the subject and is often problematic for students. Despite the importance of this concept, numerous studies ...

Existen modos muy diversos de expresar la concentración de las disoluciones [1].
Entre ellos se encuentran la molaridad (M) y la molalidad (m). En este artículo
docente se va a definir ambas variables y a describir el ...
[EN] It is known that for most students from other fields, the subject of physical
chemistry is noticed as hard and difficult. This perception could be due, in
addition to the intrinsic difficulty of the subject, to the ...
[EN] Cassava starch-chitosan films were obtained by melt bending and compression molding, using glycerol and polyethylene glycol as plasticizers. Both the starch/chitosan and the polymer/plasticizer ratios were varied in ...
[EN] The effect of incorporating different ratios of both non-heated and heated (95 ºC) buttermilk (BM) to corn starch (CS) films was analyzed in terms of its structural, mechanical, barrier, optical and bioactive properties. ...
[EN] This work studies the influence of basil essential oil, its content and the homogenization treatment on the physical properties of chitosan-based edible films. Two homogenization treatments were applied, without (H1) ...
The physical, antioxidant and antimicrobial properties of chitosan (CH)-cinnamon leaf essential oil (C) films, containing or not oleic acid (OA), were evaluated. The addition of OA led an increase in surface charge and ...
[EN] Chitosan (CH) was blended with poly vinyl alcohol (PVA) in different compositions to obtain biodegradable films (PVA90:CH10, PVA80:CH20, PVA70:CH30). Blends and neat polymer films (PVA100,CH100) were characterized for ...
[EN] Plasticised cassava starch films with 1-2% ferulic or cinnamic acid were obtained by melt blending and compression moulding. Partial losses (about 40%) of the more thermo-sensitive ferulic acid occurred during processing. ...
[EN] Chitosan films enriched with basil (B) or thyme (T) essential oils (EO) were prepared by means of two homogenization treatments, without (H1) and with (H2) microfluidization. H2 treatment led to a significant decrease ...

En este artículo vamos a definir qué es un proceso isotérmico y un proceso adiabático, y vamos a exponer las razones por las cuales no se deben confundir ambos conceptos, que no sólo no son equivalentes sino que además son ...
[EN] The use of biocontrol agents (BCA) for controlling plant diseases is an alternative to reduce the use of
pesticides. Their performance can be improved when applied in combination with coatings. Films and
coatings ...
[EN] Polylactic acid (PLA) is a sustainable material for food packaging applications. The incorporation of cinnamic acid (CA) into PLA films was studied to obtain antimicrobial films, using two different techniques for ...
[EN] In order to evaluate the impact of chitosan on the physical properties of wheat starch-glycerol films, part of the wheat starch was replaced by chitosan, and the effect of composition on the properties of both the ...
