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.

### Yacon: health benefits and technological applications

Jettana- cheawchankit, and P. In Table 1 we present the results obtained by applying different ep and times for impregnation, with a relaxation time of 10 min for all the samples. The width W in centimeters was measured perpendicular to the midrib, obtained from one end to the other, where the highest value was considered, both measurements used centimeters cm as unity Figure 1. The seedlings were transplanted 32 days after emergence.

This is an open-access article distributed under the terms of the Creative Commons Attribution License. It can be noted a trend for bakery products formulations using yacon flour, and the outcomes were positive for both technological properties as well as for sensory evaluations.

Services on Demand Article. VI has proved to be an useful method to enrich fruit and vegetable tissue with desirable solutes e.

## Journal of Obesity

Thus, to be simpler and show only the product between the variables length – L and width – Wlower SE, higher R a 2significant parameters of regression and a sobrre distribution pattern of residuals, the model chosen was: The results we obtained made it possible to quantify the amount of Aloe incorporated: According to [ 37 ]the cientificae in color is due to the fact that the gas-fluid exchange in the process of impregnation homogenizes the refractive index of the sample, which increases the transparency of the product.

Thus, the models which use the product LW to predict the yacon leaf area are more accurate higher R a 2 and lower SE.

Volumetric fraction; mass fraction; impregnation solution; physiologically active components; porous structures. Figure 5 shows the estimated response surface for the effect of these relevant process variables on mass fraction X mhd. De Pilli, and C. So, the need for this equation in the scientific literature was intended to be met. 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.

Characterization of the final product Table 4 presents the results of the chemicophysical analysis of the yacon impregnated with Aloe vera after dehydration. This tuberous roots have been attracting interest from researchers due to their nutritional and technological properties. 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. Iron bioavailability from ferric pyrophosphate in rats fed with fructan containing yacon Smallanthus sonchifolius flour.

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.

Also for sunflower, Maldaner et al. 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.

The growing scientific interest in yacon is due to its abundant source of fructan, fructo-oligosaccharides FOSinstead of starch [ 2 ].

### Models for estimating yacon leaf area

September 26 th Acemannan, a partially acetylated polysaccharide found in the Aloe vera gel, is responsible for its biological activities [ 10 ], [ 11 ], [ 8 ].

Investigation of phenolic acids in yacon Smallanthus sonchifolius leaves and sobree. From the results, it is concluded that yacon is an excellent raw material for vacuum impregnation of Aloe vera. Services on Demand Journal. Other compounds such as phenolics, organic acids, enzymes, vitamins and minerals are also present in minor quantities [ 9 ]. However, six linear models are presented, considering that these models best satisfied the pre-established statistics.

By removing the air from fruit pores and introducing specific solutes, vacuum impregnation can help to prevent browning [ 16 ]. Estimation of leaf area for greenhouse cucumber by linear measurements under salinity and grafting.

Thus, the authors decided to compare these models, choosing among them the best one, statistically.

Raiz tuberosa de yacon Smallanthus sonchifolius: How to cite this article. Effects of post-harvest treatments on the carbohydrate composition of yacon roots in the Peruvian Andes. Journal of Nutrition, v. In the early nineties was introduced in Cientfiicas the yacon potato planting. Allometric models for non-destructive leaf area estimation of Jatropha curcas. Effects of oligosaccharides on the fecal flora and non-specific immune system in elderly people.

Also considering that these studies will be extremely precious for the knowledge of adaptation and management of yacon in Brazil and worldwide. Journal of Geophysical Research It can be noted a trend for bakery products formulations using yacon flour, and the outcomes were positive for both technological properties as well as for sensory evaluations Key words: Ana Paula Gusso, email: The prebiotic potential, glycemic index reduction and improvement of bone health are the effects that stand out yaconyacn the in vivo researches.

Matrix engineering, using a vacuum impregnation technique, was employed to incorporate components with physiological activity into the pores present in the yacon flakes. The index of agreement between estimates of the model chosen and the values of leaf area investigacionss was carried out using index d Willmott et al.

As regards the effect of applying high vacuum pressures for prolonged processing times, a direct effect was observed, namely, there was an increase in volume fraction X and mass fraction X mhd as this factor pressure increased.

Yacon has no specific growing technologies, because its commercial exploitation is recent.
