Evaluación de distintas técnicas de conservación en peras "Packham's Triumph" mínimamente procesadas
(Universidad de Chile, 2012)
Las operaciones unitarias involucradas en la obtención de frutas mínimamente procesadas en fresco (MPF) limitan su vida útil, debido a un aumento en la tasa respiratoria, respuesta y producción de etileno, y pardeamiento enzimático. En el presente...
New eating habits and current lifestyle with little time to prepare balanced meals, have caused a demand for natural, fresh, healthy and ready to consume products as minimally processed fruits (MPF), also known as fresh-cut fruits, becoming fresh-cut pears an interesting alternative. The unit operations involved in obtaining these products limit their life, due to an increase in respiratory rate, ethylene synthesis and response, and as well as initiate enzymatic browning reactions by the contact of enzymes with substrates located in different parts prior cutting. In the present study, fresh-cut pears dipping in: citric acid (CA) (2 g·L-1), ascorbic acid (AA) (2 g·L-1), L-cysteine (C) (2 g·L-1) and ethylenediaminetetraacetic acid (EDTA) (1 g·L-1) was evaluated, during 8 days at 5 °C. The treatments used were: control on water; CA + AA + C; CA + C + EDTA; AA + C + EDTA; CA + AA + EDTA; CA + AA + C + EDTA. Respiratory rate, firmness, chemical and color parameters, sensory quality and polyphenol oxidase activity (PPO) were evaluated. A completely randomized design was used, with six treatments and variance analyses with a 5 % of significance were used. After processing (1-4 h) all slices had higher respiration rates (23,2 to 36,2 mg CO2·kg-1·h-1) compared with the whole fruit (6,9 mg CO2·kg-1·h-1). After 6 days, there were not significant differences between treatments (6,7 to 10 mg CO2·kg-1·h-1). On day 1, slices control and CA + AA + EDTA (without C) presented lightness (L) values of 73,4 and 74 respectively. Slices with C presented higher values from 77,3 to 78,3. Then on day 8 slices control and CA + AA + EDTA, showed values of 73,8 and 70,8 respectively and slices with C had the highest values from 74,1 to 75,6. Similar behavior was observed in the PPO activity. Slices with C had the lowest activity with values ranging from 1,3 to 2,7 U·mg-1·prot-1, contrary to slices with C slices without C presented 3,4 to 3,9 U·mg-1·prot-1 values. On the visual aspect slices with AC + C + EDTA and AC + AA + C + EDTA were the better evaluated. Antibrowning agents did not influence the chemical and firmness parameters. And it was concluded that treatment with C, were most effective in reducing enzymatic browning....

Caracterización técnico-económica de la implementación de un sistema biodinámico en un vilñedo convencional cv. cabernet sauvignon en el Valle de Limarí
(Universidad de Chile, 2006)
: efectuar una caracterización técnica de la producción de uva del cultivar Cabernet Sauvignon bajo el sistema biodinámico, orgánico y convencional en el Valle de Limarí y realizar una evaluación económica de la producción de uva de dicho cultivar bajo el...
The purpose of this study was to evaluate both the technical and economic feasibility of cv. Cabernet Sauvignon grape production under the biodynamic system in the Limarí Valley. The specific objectives were to carry out a technical characterization of cv. Cabernet Sauvignon grape production under the biodynamic, organic and conventional systems in the Limarí Valley, and an economic evaluation of the grape production under the biodynamic system, comparing this with the organic and conventional production of the cultivar in study. The technical characterization was carried out based on a description of the handling and technical requirements in the agronomical managements of the canopy, pruning, control of the fruit-bearing load, fertilization, undergrowth control, plagues and diseases during the conversion time to the biodynamic and organic systems of production. The same description was completed for the production under the conventional system. The economic analysis was carried out based on the study of the investments and costs of the productive seasons during the conversion of the production of cv. Cabernet Sauvignon grape under the biodynamic, organic and conventional systems. With the information obtained, cash flows for a period of 15 years, were calculated for each of the three productive systems and the evaluation indicators of Net Present Value (NPV$) were discounted to 12 % and the Return Internal Rate (RIR%) were applied to each of them. The biodynamic flow was submitted to an analysis of sensibility with regard to the two parameters considered relevant: the price of the grape and the costs of production. This investigation leads to the conclusion that: The resources and conditions, in terms of the culture and locality of the study, exist to make the production of the cv. Cabernet Sauvignon grape technically viable under a biodynamic system of production in the Limarí Valley. The major operational costs registered in the management of the biodynamic and organic systems of production correspond to the labor of fertilization, the costs being highest in the biodynamic system. The costs most represented in the management of the conventional system correspond to the inputs of the control of plagues and their application. The biodynamic and the organic systems, are productive systems highly intensive in the use of work hand, and the conventional system is highly intensive in the use of machinery. In the biodynamic flow the NPV12 % is 3.659.978,56 $ and the RIR is 16 %; in the organic flow the NPV12 % is 3.605.368,50 $ and the RIR is 17 %; and in the conventional flow the NPV12 %is 3.252.545,38 $ and the RIR is 17 %. All of the productive systems are economically feasible, with the biodynamic project appearing to be the most profitable. In the sensibility analysis applied to the biodynamic project, the price of the grape is the parameter that generates major variation in the indicators of evaluation, as much in the value of the NPV12 % as in the RIR....
