The experiment evaluation was carried out days after seedling transplanting, 64 yacon plants being collected, at random in a representative way, which showed average of This fact justifies that more studies are necessary on the growing and development of this species. The functional food market has grown significantly as a consequence of increased promotion and consumers awareness of healthy eating and lifestyle [ 1 ].

The replacements of inter- and intra-cellular gas with the impregnation solution, which presents a viscosity higher than that of the internal gas, can positively influence the product consistency and turgidity [ 38 ] As regards color, the sensory evaluation showed non-significant results; color is one of the most important quality parameters in dehydrated products.

Color is a highly important characteristic in the physical assessment of the quality of foods and can have a negative effect on the presentation of the product.

However, the right choice of the models mentioned must go through a detailed statistical study in order to guarantee that the selected equation to estimate the leaf area is practical, simple and accurate Fialho et al.

Subsequently, different pressures and timings were applied, followed by a further 10 min at atmospheric pressure.


Establishing the effective volume fraction In Table 1 we present the results obtained by applying different pressures and times for impregnation, with a relaxation time of 10 min for all the samples. All the conditions necessary for the production of yacon and Aloe vera are found in Peru, which makes it necessary to carry out research to develop new products or to apply new processing techniques.

De Pilli, and C. Linear regression of the experimental data shows that the volume fraction intercept value is an average of 0.

Yacon: health benefits and technological applications

On another hand, Aloe vera has enjoyed a long history of providing a myriad of health benefits, being one of the herbal remedies most frequently used throughout the world [ 7 ], [ 8 ]. Protective effects of yacon Smallanthus sonchifolius intake on experimental colon carcinogenesis. Studies in the Heliantheae Asteraceae.

Tem sabor adocicado e refrescante. Thus, the authors decided to compare these models, choosing among them soobre best one, statistically. One of the essential morphologic variables which influence plant growth is the leaf area. This study aimed to determine a regression equation yaconyaconn expresses, accurately, the functional relationship between the leaf area and the measurements of the yacon leaf blade.

This is the main obstacle for its development. Antioxidants in yacon products and effect of long term storage.

In that regard, [ 30 ] found a similar increase for samples of apple, melon, papaya, and peach. Moisture, proteins, fat, ash, fiber and carbohydrates by differencesoluble solids, titratable acidity and pH; density: The effect that high vacuum pressures have on parenchymatous cell deformation, together with the difference in size between the molecules of the solute and of water, makes diffusion of the solute through the cell membrane difficult [ 26 ].


Results and discussion 3. Such is the case mentioned in [ 30 ]where banana, mamey and mango displayed a linear increase in the values of X up to certain limits approximately mbarafter which the level of impregnation decreased. The d value is calculated using the following equation:.

Models for estimating yacon leaf area

The growing scientific interest dientificas yacon is due to its abundant source of fructan, fructo-oligosaccharides FOSinstead of starch [ 2 ]. In order to calculate the average volume fraction, we took the values with data obtained after five minutes, which are plotted vs.

Given that r is defined as the relation between atmospheric pressure and working pressure, the x axis provides information about the index of pressure-gradient intensity [ 29 ]. Figure 2 shows the effects of each independent variable on volume fraction X and Figure 3 shows the effects on mass fraction X mhd.

Changes in color are due to the concentration of pigments or their degradation. The invesstigaciones stressed the importance of internal variables, such as the number and diameter of pores, the mechanical properties of the solid matrix as well as the spatial distribution and characteristics of the cells, and also the type of fluid liquid or gas present in the intercellular space, which have to be taken into consideration in order to make precise adjustments to vacuum impregnation treatments.
