The application of edible coatings containing natural antimicrobials is a postharvest conservation technology in fruits that have generated interest. This research aimed the determination of the edible coating composition and the concentration of essential oil that allows optimizing the physical-mechanical characteristics for its application in the conservation of blueberries. The antimicrobial activity of the essential oils of cinnamon and lemon was determined, resulting in a minimum inhibitory concentration of 0.3% in both cases. After applying the Box Behnken design of the Response Surface Methodology (RSM), the optimal treatment for edible coating with cinnamon essential oil 0.3% was determined: aloe vera gel 18.40%, gelatin 2%, and glycerol 0.055% obtaining values of 27.95% solubility, 0.90 mm of deformation and 3.34 N of breaking strength. Likewise, the same procedure was followed for the coating with lemon essential oil 0.3%, determining as optimal 23.94% aloe vera gel, 2% gelatin, and 0.05% glycerol, getting values of 28.06% solubility, 0.45 mm deformation, and 4.53 N of breaking strength. Finally, their applications in Biloxi blueberries were validated, preserving the main physicochemical and microbiological quality attributes during 28 days of storage at 2 °C, compared, to a control sample.
This study evaluated the effect of microencapsulation and addition of mango peel powder on the survival of Lactobacillus acidophilus and Bifidobacterium lactis, overrun, apparent viscosity, and overall acceptability of symbiotic ice cream during storage at -20 °C for 180 days. Six formulations of vanilla-flavored ice cream were prepared: three with addition of probiotic cultures at a concentration of 108 CFU/g and 0, 2%, and 3% mango peel powder microencapsulated in a sodium alginate matrix, and three with free addition. Analytical evaluations were performed after 1, 30, 60, 90, 120 and 180 days of storage. The results showed that microencapsulation of probiotics and prebiotics statistically influenced (p < 0.05) the characteristics evaluated. The formulation with microencapsulated probiotics and 2% mango peel powder was considered as the best product. This formulation is promising for future commercial application as a functional food because, at the end 180 days of storage, it showed probiotics population >106 CFU/g, 72.97% overrun, 292 mPA apparent viscosity, and good overall acceptance (7.6 points) equivalent to “I like it very much”.
A nivel mundial, Perú es uno de los principales productores de espárrago verde (Asparagus officinalis L.); este es un vegetal altamente perecible debido a su elevada velocidad de respiración y metabolismo, por lo que es muy importante conservar las características de calidad en los turiones, motivo por el cual se evaluó el efecto del ozono gaseoso (0 a 10 ppm) y tiempo de almacenamiento (0 a 30 días) sobre la pérdida de peso, luminosidad, firmeza, contenido de clorofila y contenido de lignina. Se utilizó la metodología de superficie de respuesta, aplicando un diseño compuesto central rotable. Los resultados indicaron que existió influencia significativa de las variables independientes sobre las características fisicoquímicas estudiadas, así como una adecuada bondad de ajuste del modelo de regresión cuadrático. Mediante la técnica de superposición de contornos se determinó que las condiciones óptimas para la mayor retención de firmeza (11,42 N), contenido de clorofila (12,33 mg/100 g) y contenido de lignina (7 mg/100 g) correspondieron a 6,98 ppm de ozono gaseoso hasta los 30 días de almacenamiento, con adecuadas características de calidad en los turiones.
