Markers of quality retention: colour, texture, browning, texture related enzymes and sensory properties, were analysed during storage. The use of high temperatures (50ºC) showed a positive effect on enzymes related to quality maintenance. It reduced the activity of the browning-related enzymes polyphenol oxidase and peroxidase but it increased the activity of pectin methyl esterase, an enzyme involved in the maintenance of texture. High calcium lactate concentrations (3 %) produced a reduction in the respiration rate of the salad-cut lettuce during storage, but also a loss of luminosity and greenness (a*). The use of high temperatures and intermediate calcium lactate concentrations …


Efficacy Of Innovative Anti-Microbial Decontamination Of Minimally Processed Vegetables, Christina Busquets I Tortosa Jan 2005

Efficacy Of Innovative Anti-Microbial Decontamination Of Minimally Processed Vegetables, Christina Busquets I Tortosa

Masters

Chlorine has widespread use commercially as a disinfectant wash for raw vegetables. However, it is an extremely corrosive gas and it may have severe health and environmental implications. The aim of this thesis was to find safe, alternative decontamination treatments for ready-to-eat Iceberg lettuce. The efficacy of 1% acetic acid, 2% citric acid; calcium lactate concentrations of 0.5%, 1.5%, 2.5% and 3% at wash temperature of 4,25 and 50°C, ozone alone (1 mg 1-1) and in combination with calcium lactate (2.5%) were compared with chlorine as decontaminating treatments. Microbiological analyses were performed following decontamination treatments using the pour plate method …


Living Digestibility Of Alfalfa And Barley In Llamas (Lama Glama) In The Agricultural Experimental Center Condoriri, Adelaida Alarcon Chuquichambi Jan 2005

Living Digestibility Of Alfalfa And Barley In Llamas (Lama Glama) In The Agricultural Experimental Center Condoriri, Adelaida Alarcon Chuquichambi

Theses and Dissertations

The following investigation was carried out in the Agricultural Experimental Center Condoriri (CEAC), dependent on the Faculty of Agricultural Livestock Sciences and Veterinary Medicine, located to the North of the Province border of the Department of Oruro, a distance of 12 km from the town of Caracollo and 49 km from the city of Oruro. The production of llamas and alpacas in our country is an activity of ecological, social, and especially ecological importance for Andean inhabitants. In nutrition, the fundamental factor is the power of absorption; this is because the yield of animal production depends on the quantity and …
