ABSTRACT
The purpose of this research is to determine the effects of temperature on iron, zinc and fiber,
on cookies made from wheat flour, ginger and pineapple epicarp and to assess whether or not it
affects the organoleptic and nutritional quality of these foods and in turn this research presents
an alternative processing and industrialization of ginger and pineapple epicarp, to establish its
dosage as a source of dietary fiber of iron and zinc in the production of cookies
This is with the purpose of improving the nutrition of the population in Guatemala, contributing
conventional products with an enrichment of the nutritional content using natural organic raw
materials. For this purpose, flour high in fiber, iron and zinc was developed using ginger flour
and pineapple epicarp before the dehydration of each compound, taking advantage of raw
materials that are little used or are in disuse in the country, the pineapple in its Most of them
only process the pulp of this fruit and as for ginger, its use is very limited in the culinary and
industrial area. Guatemala is among the first twenty producers of pineapple worldwide, so it has
great potential to provide this raw material with high nutritional level that should be exploited
and ginger proliferates quickly when grown in different climates.
The importance of dietary fiber in nutrition along with the recommendation of increased
consumption has led the food industry to look for alternative sources. It has been found that the
dietary fiber of fruits and vegetables, in general, are of better quality than that coming from food
grains (cereals and legumes). The importance of the iron and zinc minerals in the diet lies in the
prevention of diseases such as anemia, malformations, anemia, lack of appetite, respiratory
diseases, poor growth and development, among others; and in the case of fiber which provides
a good intestinal transit and contributes to the prevention of colon cancer, diverticulosis,
constipation problems, gastritis, hiatus hernia, peptic ulcer, among others.
The results of this investigation show that ginger and pineapple epicarp can be used as an
enrichment of common flours, through physicochemical analysis and sensory analysis. The
ginger and pineapple epicarp were dehydrated, then ground to obtain flour, which was mixed
with wheat flour and a new flour was made high in fiber, iron and zinc, which was later used in
cookies. The results of the proximal chemical analysis allowed to establish that cookies with
ginger flour and pineapple epicarp have a higher percentage of crude fiber and minerals such as |
