Tecnología del salado y secado artificial de la merluza (merluccius gayi peruanus)

Describe el desarrollo del proceso de salado y secado artificial de la merluza, como un método alternativo a la producción de filetes y bloques congelados, comprendiendo las experiencias comparativas de métodos de salado e igualmente las condiciones termodinámicas del aíre para el secado artificial, estudios de estabilidad de almacenamiento del producto experimental, calidad, rendimiento y aceptación por el consumidor. Además, se presenta sugerencias para las normas de procesamiento y calidad del producto.

Secado de ajo elefante : allium ampeloprasum

Los estudios realizados en la Argentina sobre poscosecha del género Allium se refieren a A. sativum, no habiéndolos sobre Allium ampeloprasum (ajo elefante), de buenas características organolépticas (sabor más suave) y creciente demanda en los mercados internos y externos. Por tal motivo se decidió investigar la incidencia del método de secado en su pérdida de peso comparando el procedimiento tradicional en caballete con el realizado en horno solar con circulación forzada de aire. En ambos casos se efectuaron 5 repeticiones para control de pérdida de peso. Se sacaron muestras al azar de los distintos niveles de las paseras para establecer la humedad en bulbo entero, bulbo pelado y hojas, efectuando 3 repeticiones para cada determinación y tratamiento. La duración de los tratamientos se determinó en base a la humedad en hoja y bulbo entero, puesto que la variación en bulbo pelado no fue significativa. Los datos fueron evaluados con el análisis de la varianza utilizando un nivel de significancia del 5 % y la prueba de Duncan. En las condiciones del ensayo, el secado en horno solar adelanta 6 días la terminación, con una pérdida de peso del 30,7 %.

The S.T.A.B. Trial - Standardised Testing of Artificial Blood. A comparative study of various products that may be used as artificial blood for high fidelity simulation training in the critical care setting

Aim: In the current climate of medical education, there is an ever-increasing demand for and emphasis on simulation as both a teaching and training tool. The objective of our study was to compare the realism and practicality of a number of artificial blood products that could be used for high-fidelity simulation. Method: A literature and internet search was performed and 15 artificial blood products were identified from a variety of sources. One product was excluded due to its potential toxicity risks. Five observers, blinded to the products, performed two assessments on each product using an evaluation tool with 14 predefined criteria including color, consistency, clotting, and staining potential to manikin skin and clothing. Each criterion was rated using a five-point Likert scale. The products were left for 24 hours, both refrigerated and at room temperature, and then reassessed. Statistical analysis was performed to identify the most suitable products, and both inter- and intra-rater variability were examined. Results: Three products scored consistently well with all five assessors, with one product in particular scoring well in almost every criterion. This highest-rated product had a mean rating of 3.6 of 5.0 (95% posterior Interval 3.4-3.7). Inter-rater variability was minor with average ratings varying from 3.0 to 3.4 between the highest and lowest scorer. Intrarater variability was negligible with good agreement between first and second rating as per weighted kappa scores (K = 0.67). Conclusion: The most realistic and practical form of artificial blood identified was a commercial product called KD151 Flowing Blood Syrup. It was found to be not only realistic in appearance but practical in terms of storage and stain removal.
