“…The films were quite brown, opaque and appeared to have particulates. The resulting films were similar to PLA/pectin composite film developed by Jin et al (2009) andLiu et al (2009) and Hydroxy Propyl Methyl Cellulose (HPMC) film developed by Chana-Thaworn et al (2011a, 2011b. Color characteristics of film determined instrumentally are shown in Table 2.…”

“…However, this film had higher transparency when compared with other bio-based packagings. Edible HPMC films incorporated with Kiam wood extracts had the transparency range from about 1.4 to 1.8 (Chana-Thaworn et al, 2011b) which are lower than those of PLA/SP biocomposite film. The optical characteristics of PLA/SP film may be improved by the addition of natural sawdust particle subjected to clarification or bleaching step before compounding with PLA.…”

“…It was lower than those of PLA film with 5 to 16.6% PEG400 as plasticizer and PLA/chitosan composite film which had about 5% and 35% solubility, respectively (Sébastien et al, 2006). Normally, PLA and its composites are found to have very low water solubility compared with other bio-based materials especially protein-and polysaccharide-based materials which water solubility was around 5-50% (Chana-Thaworn et al, 2011a, 2011bHoffman et al, 2001;Ko et al, 2001;Padgett et al, 1998). The high water solubility of the film made from bio-based polymers remained a major problem.…”

“…These phenomena increase the mean free volume between polymer chains (Gontard et al, 1993). The effect of adding spice extracts to films has been also tackled -and, in all cases, significant decreases in TS and YM were observed (Chana-Thaworn et al, 2011;Fang, Tung, Britt, Yada, & Dalgleish, 2002;Rojas-Graü et al, 2007).…”

The goal of this research effort was to assess the efficacy of edible films produced from whey protein isolate (WPI) and glycerol, including incorporation of lactic acid (LA) and propionic acid (PRO), chitooligosaccharides with nominal MW of 3 kDa (COS) and natamycin (NA) as antimicrobial agents. Their features were evaluated in vitro via agar diffusion and viable cell counting, against spoilage microflora often found contaminating cheese surfaces. The effect of incorporating the aforementioned compounds upon thickness, moisture content (MC), solubility (S), density (ρ s ), water activity (a w ) and water vapor permeability (WVP), as well as upon tensile and optical properties of those films were also evaluated. Films formulated with LA, PRO or COS exhibited antimicrobial activity against all microorganisms tested, yet the viable cell count assay was more sensitive and reproducible. COS was the most active against Gram-negative bacteria, whereas LA was the most active against Gram-positive ones. NA was not active against bacteria, but displayed the strongest effect against yeasts. Incorporation of said antimicrobial compounds did not significantly (pN 0.05) affect film thickness, yet it significantly (p b 0.05) reduced tensile strength (TS). Incorporation of LA and NA in particular did not significantly (pb 0.05) affect MC, S, ρ s , WVP, elongation at break (EB) and Young's modulus (YM) values; however, a statistically significant increase (pb 0.05) of MC, S and WVP, together with a statistically significant decrease (p b 0.05) of ρ s were attained upon incorporation of PRO or COS. Moreover, PRO produced the highest variation (pb 0.05) in EB, TS and YM, whereas COS produced the highest change (pb 0.05) in optical properties.

* Autor a quien debe ser dirigida la correspondenciaRecibido Ene. 5, 2015; Aceptado Mar. 12, 2015; Versión final Abr. 25, 2015, Publicado Oct. 2015 Resumen En la presente investigación se elaboraron biopelículas activas a base de alginato, almidón de maíz y extracto acuoso de toronjil (Melissa officinalis L), evaluando su incidencia en la vida útil microbiológica del camarón blanco del pacifico (Penaeus vannamei). Para la estimación de la vida útil se realizaron cinéticas de crecimiento de microorganismos indicadores (aerobios mesófilos) modeladas matemáticamente utilizando la ecuación de Baranyi y Robert utilizando el programa DMFIT para obtener los parámetros cinéticos de crecimiento microbiano a diferentes temperaturas. Finalmente la ecuación de MonodHinshelwood fue utilizada para estimar la vida útil de los camarones. Los resultados indicaron que es posible utilizar biopelículas a base de alginato, almidón de maíz y como sustancia antimicrobiana extracto acuoso de toronjil para la conservación de camarones (Penaeus vannamei), debido a que se obtuvieron incrementos del 33% aproximadamente en la vida útil de camarones (Penaeus vannamei) recubiertos con las biopelículas.

Microbial growth kinetics using as indicators microorganism aerobic mesophilic bacterial modeled mathematically through Baranyi y Robert equation by the program DMFIT were used for determinate the microbial growth parameters at different temperatures. Finally Hinshelwood -Monod equation was used to estimate the shelf life of the shrimp. The results indicated that is possible obtain binary biofilms containing aqueous extract of lemon balm for the shrimp conservation, because increments of 6 days were obtained in the shelf life of shrimp coated with biofilms
