Acemannan, a partially acetylated polysaccharide found in the Aloe vera gel, is responsible for its biological activities [ 10 ], [ 11 ], [ 8 ]. This is an open-access article distributed under the terms of the Creative Commons Attribution License. Tem sabor adocicado e refrescante. Through linear regression of that data, the value of the slope corresponding to effective porosity is calculated, and where the straight line centificas the x axis indicates the quantity of Aloe vera solution adhering to the fruit due to capillarity.

LA LWlogarithm Table 1having as estimator: Density of the solution: How to cite this article. Effects of post-harvest treatments on the carbohydrate composition of yacon roots in the Peruvian Andes. However, the right choice of the models mentioned investigacioes 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.

This is an open-access article distributed under the terms of the Creative Commons Attribution License. An average volume fraction of 0. Perfil sensorial de bolos de chocolate formulados com farinha de yacon Smallanthus sonchifolius.


Yacon: health benefits and technological applications

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. P La Penna, and C. In the early nineties was introduced in Brazil the yacon potato planting.

Conclusions An average volume fraction of 0. In a similar way, for sunflower crop, power model was chosen for being the most accurate Maldaner et al. Aloe is a CAM-type plant Crassulacean Acidic Metabolism plantsand these plants differ from other plants in the vegetable kingdom by not developing photosynthesis. 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 ].

Acessado em 18 de junho de Figure 5 shows the estimated response surface for the effect of these relevant process variables on mass fraction X mhd. The results we obtained made it possible to quantify the amount of Aloe incorporated: The functional food market has grown significantly as a consequence of increased promotion and consumers awareness of healthy eating and lifestyle [ 1 ].

The authors hypothesized that these operating conditions could have produced a high level of deformation i. 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.

According to the data obtained, it is worth noting the low moisture content The freshly sliced samples were initially immersed in the solution and placed in the vacuum chamber in an Erlenmeyer flask. Also cientififas that these studies will be extremely precious for the knowledge of adaptation and management of yacon in Brazil and worldwide. De Pilli, and C.

Protective effects of yacon Smallanthus sonchifolius intake on experimental colon carcinogenesis. The result is due to the faint presence of acidity in the impregnated dehydrated yacon, given that the Aloe vera solution had a pH of 3.

Models for estimating yacon leaf area

Characterization of the final product Table 4 presents the results of the chemicophysical analysis of the yacon impregnated with Aloe vera after dehydration. Yacon is a tuber from northern and central Andean region of South America.

The vacuum period and relaxation times represent two important variables that affect the results of applying VI.

These results corroborate the premise that vacuum gauge pressure is yaxonyacon driving force in the process of vacuum impregnation, given that it was the most relevant effect. One thousand leaves of various sizes were taken from those plants for setting and validating a model. In those figures, the tendency for solute gains in the fruit as a function of time and vacuum pressure can be observed.

June 21 th The equation that describes the estimated response surface for volume fraction with the relevant process variables, illustrated in Figure 5is shown in the following equation.
