Article Abstract
This study evaluates the effects of intra-amniotic administration of yacon (Smallanthus sonchifolius) flour soluble extracts (YFSE) on intestinal bacterial populations, brush border membrane (BBM) functionality and morphology, by using the Gallus gallus model. The YFSE increased (p < 0.05) relative abundance of Lactobacillus, Bifidobacterium, Clostridium and E. coli compared to 18MΩ H2O. The YFSE had systematic effect on BBM functionality, via the upregulation of zinc (zinc transporters - ZnT1, ZnT7 and ZIP9) and iron (ferroportin, Duodenal cytochrome (DcytB) transporters, sucrose isomaltase (SI), and down regulation of Interleukin 1 beta (IL1β), and hepcidin genes expression when compared to the inulin administered group. The YFSE administration increased glycogen concentrations in pectoral muscle compared to noninjected and 18 Ω H2O groups, however, did not change gene expression of enzymes related to glycolysis (phosphofructokinase) and gluconeogenesis (glucose-6 phosphatase). The YFSE increased the depth of crypts, crypt goblet cell diameter, number and type (acidic), and villi goblet cell diameter and type (acidic) when compared to all other groups. Thus, YFSE demonstrated prebiotic effects resulting in improving intestinal bacterial populations profile, BBM functionality, digestive and absorptive capabilities, intestinal morphology, glycogen status and immune system.

Yacon potato (Smallanthus sonchifolius) is an Andean wild tuberous root, rich in inulin and fructooligosaccharides, which has not yet become a major cultivar. The increasing demand for safe and convenient products that benefit health, such as functional foods with prebiotic effects, favors the addition of yacon potatoes as flour in processed foods. Thus, this study aimed (i) to develop and characterize two formulations of typical Brazilian cheese bread premixes (CBPs) made of cassava starch added with yacon potato flour (YPF) in different proportions (F1: 2%, and F2: 4%), and (ii) to carry out physical, physicochemical, and sensory analyses on the cheese bread rolls (CBR) developed from CBP and compare to the control formulation (C).

Background/objectives: Yacon syrup () has gained attention due to its high concentration of fructooligosaccharides (FOSs) and associated health benefits. This systematic review aimed to evaluate the effects of yacon syrup on metabolic parameters and intestinal health in humans over the last decade.
Methods: Following PRISMA guidelines, we conducted a systematic search in databases, including Medline (PubMed), Science Direct, Embase, Scopus, and SciELO, up to October 2024.

Yacon is a tuber known as a healthy food due to its effects as an antidiabetic, anti-inflammatory, anticancer, and prebiotic agent; it is rich in fructooligosaccharides (FOS) and antioxidants, and due to its sweet taste and low-calorie content, it is used as a substitute for ordinary sugar. This research aimed to evaluate the influence of the composition of the feed and the microencapsulation process by spray drying (SD) on the properties of a yacon powder mixture (YP). Response surface methodology with a central composite design with a face-centered composition (α = 1) was used, considering the independent variables: inulin () (3-5% w/w), maltodextrin (MD) (3-5% w/w), air inlet temperature (AIT) (140-160 °C), air outlet temperature (AOT) (75-85 °C) and atomizer disc speed (ADS) (18000-22000 rpm), and the dependent variables: moisture (X), water activity (a), hygroscopicity (Hy), solubility (S), particle size (percentile D, D, and D), total phenols (TP), antioxidant capacity (ABTS and DPPH), color (CIE-Lab*) and yield ().
