Vinegar has been elaborated from apple juice by inmersed fermentation at room temperature. The process was developed in two stages, firstly, the alcoholic termentation was carried out using Saccharomyces Cerevísíae yeast, Ellipsoideus variety. Secondly, an acetic fermentation was carried out using acetobacter. The global yield of the process, based on row material usage was around 52%. The product obtained has an acidity of 6,8% in acetic acid and fulfill the market requirements.

In Peru peach varieties, which are sold in markets throughout the year occur. Mostly pulp but not seeds and bones of the seeds consumed. In this work the production of activated carbon from bones with a yield of 20% and an absorption rate of 50% is reported. The essential oil obtained from the seeds using ethanol as solvent. The product obtained proved to be of good quality with pe 180 ° C

Tests have been conducted for paperboard from waste paper. The concentrations by weight of waste paper was 0.5%, O. 7%, 1% and 2%. The board obtained was tested for tensile strength. The results indicate that the yield strength decreases with the pulp concentration whereas rupture length erratic behavior.

This work describes a technologycal process to obtain alcohol from rice bran.The optimum time of fermentation was 12 hours with a yield production of 57% based on starch contents in the rice bran.

En el presente trabajo se describe el proceso tecnológico seguido para obtener alcohol a partir del polvillo de arroz. El tiempo óptimo de fermentación fue de 12 horas y el rendimiento de producción de alcohol de 57% basado en el contenido de almidón de la materia prima.

In this work dehydration of paprika(Capsicum annum L.) in solar and cabinet was compared, 276 and 353 ASTA color respective1y was obtained. Therefore the high ASTA color is produced, when dehydration is carried out in cabínet dryer.

This work describes how to obtain honey from yacón (Polimnia sonchifolia) in Pilot Plant. Also we determined that the content of inulin in the proccesed honey is 25.4%.

El presente trabajo describe el procedimiento tecnológico seguido para obtener una miel o jarabe de yacón (Polimnia sonchifolia) en planta piloto y la determinación cualitativa y cuantitativa de la inulina que alcanza en promedio un 25.4%.

It has been obtained the mass and heat transfer coefficients from experimental data of the granular- cereals drying such as rice, wheat, barley and oat in a conventional spouted bed column. The range of mass air flow varies from 5.2 and 40 kg/sm2. The mass transfer coefficients varies from 0.331 and 0.789 Kg/(sm2atm), and heat transfer coefficient varies from 43.7 and 53.8 W/m2K
