They open their stomata at night, thereby avoiding transpiration during periods of great daytime heat, and convert carbon dioxide to malic acid.

Results and discussion 3. The authors highlight that values of standard error of estimates SE found in this study were lower than the ones observed by other authors when they used estimators of leaf area in leaf morphology similar to the yacon, for example, Silva et al.

Information related to these technologies is rare in the phytotechnical area, only some notes taken by Vilhena et al. The functional investugaciones market has grown significantly as a consequence of increased promotion and consumers awareness of healthy eating and lifestyle [ 1 yaconnyacon. Algumas delas podem investigacjones visualizadas na tabela 1. Allometric models for non-destructive leaf area estimation in coffee Coffea arabica and C. AI samples unimpregnated pineapple presented values of porosity lower than vacuum impregnated samples, which can be easily explained considering that vacuum application modify the porous structure, causing its expansion [ 34 ].

The prebiotic potential, glycemic index reduction and improvement of bone health are the effects that stand out in the in vivo researches. In order to verify the adequacy study of the model chosen in the previous step, the authors, initially, adjusted to a new simple linear regression model without intercept LRMWIyaconuacon to the leaf area values measured by the leaf area integrator in the observations LA obs with the predictives by the regression model adopted LA est.

Jettana- cheawchankit, and P. Tem sabor adocicado e refrescante. Prebiotic effectiveness of fructans of different degrees of polymerization. For the nondestructive determination of yacon leaf area, several linear and nonlinear models were fitted between length Lwidth W and leaf area observed LA obs data not shown.

Yacon: health benefits and technological applications

Cientiflcas, the need for this equation in the scientific literature was intended to be met. Smallanthus sonchifolius and Lepidium meyenii – prospective Andean crops for the prevention of chronic diseases. By optimizing maximizing the process, the highest volume fraction and mass fraction that is obtained is Conclusions An average volume fraction of 0.

Food investigacoones Chemical Toxicology, v. De Pilli, and C. In the early nineties was introduced in Brazil the yacon potato planting. Those authors put forward the hypothesis that 30 min is the time necessary to reach a situation of equilibrium, after which no difference in solids gain is to be observed.

Effects of oligosaccharides on the fecal flora and non-specific immune system in elderly people. For one group of these fruits they observed a greater impregnation in line with an increase in vacuum pressure, but for the other group the values of X increased with an increase in the vacuum level up to a maximum, after which impregnation was slightly reduced.

Journal of Ethnopharmacol, v. During VI, the vegetable porous fraction composed by the intercellular spaces, is filled by an external solution to a degree that depends on various factors including the applied process conditions sub-atmospheric pressure level, process duration and temperaturethe osmotic pressure and viscosity of the impregnation fluid [ 20 ]the size and shape of the samples, its effective porosity pore size and distribution which affects the capillary pressure of fluids within the vegetable tissue and its response to mechanical stress [ 18 ], [ 21 ], [ 22 ], [ 23 ] Bearing in mind, the new methodologies for obtaining foods with added value, and the wide range of possibilities for capitalizing on yacon, our aim is to evaluate the response to the application of the technique of vacuum impregnation with a solution of Aloe vera in order to create products that can be produced on an industrial scale, nationally and internationally.

The most important effect is pressure, as shown in Figure 6. One thousand leaves of various sizes were taken from those plants for setting and validating a model. As can be seen in Figure 1the yacon sample displayed a linear increase in volume fraction, which makes it clear that its plant tissue is subject to low or almost non-existent deformation.

The slope is 0. September 26 th 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 ]. O cultivo do yacon no Brasil. The equation that describes the estimated response surface for volume fraction with the relevant process variables, plotted in Figure 4is shown in the following equation.


April 27, ; Accepted: The development of the mass was recorded at the beginning and end of the process in order to calculate the volume fraction X. Effects of post-harvest treatments on the carbohydrate composition of yacon roots in the Peruvian Andes. The substitution with the Aloe vera solution rich in carbohydrates of the yacon pores typical of the gel of the parenchymatous tissue of Aloe vera also contributes to the carbohydrate content of the final product; according to the literature, monosaccharides and polysaccharides such as glucomannan are present in Aloe vera.

VI has proved to be an useful method to enrich fruit and vegetable tissue with desirable solutes e. Effect of the impregnation process In order to analyze better the nature of the changes to the product during the different operations it undergoes, the behavior of the yacon samples during VI with the Aloe vera solution was studied.

This fact justifies that more studies are necessary on the growing and development of this species. On the other hand, Aquino et al.

Characterization of the final product Table 4 presents the results of the chemicophysical analysis of the yacon impregnated with Aloe vera after dehydration. When the vacuum period increases, the gases are completely eliminated. Many studies in vivo and in vitro were carried out with yacon and products produced from it, showing its health benefits, besides having great technological potential for developing new food products.

The statistical criteria to evaluate the best regression model were based on: Dietary modulation of the human colonic microbiota: The coefficient of determination adjusted for the degrees of freedom of the models tested were: Also for sunflower, Maldaner et al. Raiz tuberosa de yacon Smallanthus sonchifolius: Estimation of leaf area for greenhouse cucumber by linear measurements under salinity and grafting.
