From the results, it is concluded that yacon is an excellent raw material for vacuum impregnation of Aloe vera.

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. European Journal of Clinical Nutrition, v. Centro Internacional de La Papa. The values found ranged ceintificas “zero” without agreement to “one” perfect agreement.

In general, the higher the porosity, the higher the level of impregnation [ 29 ], [ 33 ] showed that the levels of impregnation were directly correlated with the porosity values of the vegetables. Figure 5 shows the estimated response surface for the effect of these relevant process variables on mass fraction X mhd. All the criteria evaluated during the validation indicate that the model chosen show good adjustment and high reliability.

Algumas delas podem ser visualizadas na tabela 1. LA LWlogarithm Table 1having as estimator: The vacuum period and relaxation times represent two important variables that affect the results of applying VI. Yacon is a tuber from northern and central Andean region of South America. Journal of Nutrition, v. However, six linear models are presented, considering that these models best satisfied the pre-established statistics.

The length L in centimeters was measured along the midrib, from the base to the leaf apex, disregarding the petiole. This may also be due to the use of Aloe vera, because of its chemical composition and the amount of phenolic compounds that inactivate the polyphenol oxidase that is responsible for enzymatic browning in many fruits.


Fluctuations of oligofructan contents in tubers of yacon Polymnia sonchifolia during growth and storage. The leaf area evaluation has been carried out directly through digital integrators and indirectly, through associative mathematical models Silva et al.

Smallanthus sonchifolius and Lepidium meyenii – prospective Andean crops for the prevention of chronic diseases. Optimized parameters were identified as 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 Field Crops Research, v.

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 LRMWIrelating 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.

The vacuolar accumulation of CO from organic acids, specifically malic acid, makes it possible to quantify its content and in this way to calculate the total presence of Aloe. Enzyme kit for L-malic acid, which contains glycylglycine buffer 6 mL, 1 M, pH Table 2 shows the values of malic acid mass fraction X MHD that were established:.

Information related to these technologies is rare in the phytotechnical area, only some notes taken by Vilhena et al.

Models for estimating yacon leaf area

Estimating the area of trifoliate and unequally imparipinnate leaves of strawberry. Investigation of phenolic acids in yacon Smallanthus sonchifolius leaves and tubers. Thus, the models which use the product LW to predict the yacon leaf area are more accurate higher R a 2 and lower SE. 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 ].

O cultivo do yacon no Brasil. The aim of this research was to optimize the parameters for the vacuum impregnation of Aloe vera into dried yacon Smallanthus sonchifolius Poepp. English pdf Article in xml format Article references How to cite this article Automatic translation Send this article by e-mail.

Conclusions An average volume fraction of 0.

Yacon: health benefits and technological applications

The plant consumption has been noticed, significantly, since the mids. O cultivo do yacon no Brasil. Journal investigacionee Agricultural and, Food Chemistry v. This study aimed to determine a regression equation which expresses, accurately, the functional relationship between the leaf area and the measurements of investiggaciones yacon leaf blade.


Annals of Applied Biology 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.

Para tal, 64 plantas representativas da cultura foram coletadas ao acaso, em um campo experimental em pleno crescimento vegetativo. By optimizing maximizing the process, the highest volume fraction and mass fraction that is obtained is The authors highlight that values of standard error of estimates SE found in this study yaconyackn lower than the ones observed investigacinoes other authors when they used estimators of leaf area in leaf morphology similar to the yacon, for example, Silva et al.

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. Raiz tuberosa de yacon Smallanthus sonchifolius: Characterization of the final product Table 4 presents the results of the invstigaciones analysis of the yacon impregnated with Aloe vera after dehydration.

Table 4 presents the results of the chemicophysical analysis of the yacon impregnated with Aloe vera after dehydration. 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.

Response Surface Methodology RSM allowed the optimization of mass fraction and volume fraction at a pressure of
