OBTENTION OF RAW FIBER FOR HUMAN CONSUMPTION DERIVED OF ROASTED PEEL CACAOObtención de fibra cruda para consumo humano a partir de la cascara de cacao tostado
(Universidad Nacional Abierta y a Distancia, UNAD, 2010-05-08)
The objective of this article is to present a possible use of roasted cocoa hulls, which currently represents an industrial surplus in the grain processing industries, and is sold with companies that produce concentrates for animals. On daily processing plants will produce about 4 tons of roasted cocoa peel, this would be a great source to produce fiber for human consumption. The present investigation was consist in ...
ACETAL OBTAINED FROM ETHANOL AND ACID-ACTIVATED BENTONITE AS A CATALYST: AN ALTERNATIVE FOR THE SUGAR-ALCOHOL AGROINDUSTRYObtención de acetal a partir de etanol y bentonita ácida como catalizador: una alternativa para la agroindustria sucro-alcoholera
(Universidad Nacional Abierta y a Distancia, UNAD, 2010-05-08)
This study discusses the results of characterizing and activating a bentonite from the Valle del Cauca region. The betonite is used as a catalyst in the reaction to obtain 1,1-Diethoxyethane from ethanol, which can be extracted from sugar cane. Important factors are analyzed such as: the activation of the bentonite; the percentage of bentonite; the reaction temperature; and the ethanol/acetaldehyde feed ratio. In ...
Biopolymers used in the manufacture of food packagingBiopolímeros empleados en la fabricación de envases para alimentos
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
This work includes various biopolymers used in the production of food packaging such as: polysaccharides, proteins, lipids, etc. It begins with the definition and classification of polymers with a special emphasis on the process of degradation of these as an alternative solution to the environmental problem caused by the indiscriminate use of plastics.
It also sets out the different types of biopolymers used in the ...
Treatment of vinasses - recirculationEl tratamiento de las vinazas – la recirculación
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
The purpose of this minireview is to give an overview of treatments that have been applied on the vinasse, residue from the alcoholic fermentation; appoint some of its advantages and disadvantages, and then submit recirculation, as one of the best options from an economic point of view and easy implementation, for those who are not interested in the ethanol byproducts.
SACCHARIFICATION ENZYMATIC APPLIED TO THE FRESH PEA POD VARIETY PISUM SATIVUM L. FOR OBTAIN REDUCING SUGAR.Sacarificación enzimática de la vaina de arveja fresca (pisum sativum l.) variedad sabanera para obtención de azúcares reductores
(Universidad Nacional Abierta y a Distancia, UNAD, 2010-05-08)
This study describes the process of enzymatic saccharification applied to the fresh pea pod variety Santa Isabel, a content rich vegetable material lignocellulose, which can be exploited to obtain sugars. For effects of the research they thought about to apply nine treatments keeping in mind: the solvent type (deionized water and sulfuric acid), the enzyme type (Novozymes® and Alkozym®), the so much dilution relationship ...
When we speak about the main requirements that food should fulfill, we know, without a doubt, that it should be innocuous or harmless to the health of consumers. This is why it is becoming more and more necessary to implement systems and practices to ensuEvaluación del tratamiento térmico de las arvejas enlatadas (pisum sativum) en salmuera
