. / Introduction: The present study aimed to take advantage of residues such as the Persea Americana (avocado) peel to obtain flour used in the preparation of a food of high consumption in the Peruvian population, noodles. Objectives: To evaluate the nutritional composition of the production of noodles by partially substituting wheat flour for Persea Americana shell flour. Methods: Laboratory study carried out in the laboratories of the Peruvian University of Applied Sciences (UPC) and Certificaciones Del Perú CERPER. Results: Titratable acidity (1.0), ash (2.85), fiber (50.08) and moisture (6.89) were determined in avocado peel flour. Wheat flour was substituted for avocado peel flour at 0, 10, 15 and 20%, being F0, F1, F2 and F3 respectively. In F0, ash (0.56), moisture (32.7), proteins (10.13), fats (3), fiber (0.85) and carbohydrates (53.49) were determined. In F1 ashes (0.76), moisture (35.60), proteins (9.68), fats (3.20), fiber (3.44) and carbohydrates (50.76). F2 ashes (0.85), moisture (37.25), proteins (9.23), fats (3.11), fiber (5.18) and carbohydrates (49.56). Finally, F3 ashes (0.94), moisture (41.21), proteins (7.71), fats (2.66), fiber (9.88) and carbohydrates (47.48).  Conclusions: Flour and noodles met the characteristics stipulated by Peruvian Technical Standards (NTP 205.053:1987 y NTS 071-2008 DIGESA - MINSA) and CODEX (Codex Stan 152-1985). The fiber in the final product was highlighted and the microbiological parameters requested by DIGESA - MINSA were met. / Introducción: El presente estudio tuvo como finalidad aprovechar residuos como la cáscara de Persea Americana (palta) para la obtención de harina usada en la elaboración de un alimento de alto consumo en la población peruana, fideos. Objetivo general: Evaluar la composición nutricional de la elaboración de fideos mediante sustitución parcial de harina de trigo por harina de cáscara de Persea Americana. Métodos: Estudio de laboratorio realizado en los laboratorios de la Universidad Peruana de Ciencias Aplicadas (UPC) y Certificaciones Del Perú CERPER. Resultados: En la harina de cáscara de palta se determinó acidez titulable (1.0), cenizas (2.85), fibra (50.08) y humedad (6.89). Se realizaron sustituciones de harina de trigo por harina de cáscara de palta al 0, 10, 15 y 20%, siendo F0, F1, F2 y F3 respectivamente. En F0 se determinó cenizas (0.56), humedad (32.7), proteínas (10.13), grasas (3), fibra (0.85) y carbohidratos (53.49). En F1 cenizas (0.76), humedad (35.60), proteínas (9.68), grasas (3.20), fibra (3.44) y carbohidratos (50.76). F2 cenizas (0.85), humedad (37.25), proteínas (9.23), grasas (3.11), fibra (5.18) y carbohidratos (49.56). Finalmente, F3 cenizas (0.94), humedad (41.21), proteínas (7.71), grasas (2.66), fibra (9.88) y carbohidratos (47.48). Conclusiones: Harina y fideos cumplieron con características estipuladas por Normas Técnicas Peruanas (NTP 205.053:1987 y NTS 071-2008 DIGESA - MINSA) y las normas CODEX (Codex Stan 152-1985). Se destacó la fibra en el producto final y se cumplió con los parámetros microbiológicos solicitados por DIGESA - MINSA. / Tesis

The research of this thesis will focus on the performance of farm forestry trees in Mubende district, Uganda. In order to this, the research will help to fill the existing knowledge gap on the performance of farm forestry trees of east Africa specially Uganda. The conducted tree species are Markhamia lutea, Ficus natalensis, Mangifera indica, Artocarpus heterophyllus, Anitaris toxicaria, Persea americana, Albizia coriaria and Spathodea campanulata. The selection of the trees was mainly driven through the availability of age information. The trees were measured in height, age, DBH, length of commercial stem, diameter at specific height and visual observations e.g. occurrence and stem quality. To compare the performance of the conducted tree species a regression analysis with eight different functions was carried out for each tree species. The results are reproducible Stand- Height-Curves, height curves, DBH curves and curves for the single tree volume. The decision on the best curve was made on their biological plausibility and their statistical calculations. Additionally, the farmers of the trees were interviewed about their tree species for e.g. purposes of the tree, value of the wood and their own impressions on the growth of the tree species. The recommendation for the best applicable function is the Petterson function for the Stand-Height- Curve and the function of Richards for the height-, DBH- and single tree volume curve. Still these functions shouldn’t be used without comparison to other functions, especially because the used functions were developed for tree stand conditions and not specially for agroforestry conditions were the tree growth is in general higher. Additionally, an upscaling and prediction of the monetary tree values is made on the basis of the single tree volume curves and the interview results. The prediction of the farmers possible income through the cultivation of trees is made for Markhamia lutea, Ficus natalensis, Anitaris toxicaria and Albizia coriaria and assumes that 100 trees are planted on one hectare. Albizia coriaria 3.630 € achieves the highest possible extra income for the farmer followed by Ficus natalensis with 1.300 €, Anitaris toxicaria with 910€ and Markhamia lutea with 880 €. This thesis gives an example on the performance and possible monetary value of tree species in Mubende district, Uganda. Further investigation is needed to fill the knowledge gap in the performance of east African tree species and their values completely.
