“…Delgado et al 31 reviewed the potential of yacon, a tuberous Andean plant that presents high content of fructooligosaccharides and inulin [32][33] Merino-Aguilar et al 35 treated obese rats with FOS fraction extracted from Psacalium decompositum for 12 weeks and found decreased body weight, cholesterol, triglycerides, and significantly reduced cytokines IL-6, IFN-γ, MCP-1, IL-1β and VEGF levels (p<0.05) 35 .…”

PURPOSE:To address the effects of fructooligosaccharides (FOS) intake on serum cholesterol levels. METHODS:We performed a search for scientific articles in MEDLINE database from 1987 to 2014, using the following English keywords: fructooligosaccharides; fructooligosaccharides and cholesterol. A total of 493 articles were found. After careful selection and exclusion of duplicate articles 34 references were selected. Revised texts were divided into two topics: "FOS Metabolism" and "FOS effects on plasma cholesterol." RESULTS:The use of a FOS diet prevented some lipid disorders and lowered fatty acid synthase activity in the liver in insulin-resistant rats. There was also reduction in weight and total cholesterol in beagle dogs on a calorie-restricted diet enriched with short-chain FOS. Another study found that 2g FOS daily consumption increased significantly serum HDL cholesterol levels but did not ensure a significant reduction in levels of total cholesterol and triglycerides.. Patients with mild hypercholesterolemia receiving short-chain FOS 10.6g daily presented no statistically significant reduction in serum cholesterol levels. However, when FOS was offered to patients that changed their lifestyle, the reduction of LDL cholesterol and steatosis was higher. CONCLUSIONS:Fructooligosaccharides intake may have a beneficial effect on lipid metabolism and regulation of serum cholesterol levels in individuals that change their lifestyle. FOS supplementation use in diets may therefore be a strategy for lowering cholesterol.

“…Rob., es una planta andina, importante por su valor nutracéutico. Las raíces tienen alto contenido de fructooligosacáridos e inulina, y las hojas alto contenido de compuestos fenólicos (Choque-Delgado et al, 2013). Hasta finales de la década de 1990 el yacón era un cultivo marginal, de huerto familiar; luego, se promovió su producción, debido a los resultados de investigaciones realizadas, principalmente en Japón (Hermann et al, 1999).…”

“…Los estudios sobre yacón se han orientado, principalmente, a conocer la diversidad morfológica y genética (Mansilla et al, 2006;Vegas et al, 2015), y el potencial como alimento funcional y medicinal (Valentová y Ulrichová, 2003;Arnao et al, 2011;Delgado-Choque, 2013;Satoh et al, 2013). Otra línea de estudio es la producción de semilla (Manrique et al, 2014); sin embargo, existen vacíos de información sobre la agronomía, productividad, poscosecha y la fisiología de la planta, bajo diversos tratamientos culturales (Seminario et al, 2003;Manrique et al, 2005).…”

El objetivo de este trabajo fue estimar el área foliar de ocho morfotipos de yacón mediante análisis de regresión lineal simple. La investigación se realizó entre los años 2014 y 2015, en el Programa de Raíces y Tubérculos Andinos de la Universidad Nacional de Cajamarca, Perú (7° 10’ 00’’ S, 78° 30’00’’ W, 2650 msnm). Se tomaron cien hojas de cada morfotipo, incluyendo hojas de los estratos basal, medio y terminal de plantas en plena oración. Las siluetas de las hojas frescas se dibujaron en papel y se midió el largo (L) y ancho mayor de la lámina (W). El área medida (o real) de la lámina se determinó con planímetro digital. Con el área medida (variable dependiente) y los valores de largo, ancho, largo al cuadrado, ancho al cuadrado, largo x ancho y largo/ancho (como variables independientes), se realizó el análisis de regresión para cada morfotipo. En todos los morfotipos, excepto en dos, las mejores ecuaciones para estimar el área foliar, fueron aquellas en donde intervino el producto de L x W. La ecuación A= 20,41 + 0,4167 (L x W) (r2 = 0,89) permitió estimar el área foliar de los ocho morfotipos en conjunto. El área del peciolo de los morfotipos en estudio signi có 15%, respecto del área total de la hoja.

“…As such, yacon (Smallanthus sonchifolius) is considered to be the best natural source of FDS and is added to many products to promote healthy intestinal microbiota as these oligosaccharides are selectively fermented in the colon by bifidobacteria and lactobacilli and can therefore provide numerous local and systemic benefits (Dliveira et al, 2016;Sousa et al, 2015;Delgado et al, 2013;Charalampopoulos & Rastall, 2012;Roberfroid, 2007). The tuberous root of yacon is perennial, thrives in many Andean countries of South America, is generally eaten raw and its colour varies from light to dark yellow (Shi et al, 2015;Velez et al, 2013;Djansivu et al, 2011).…”

Optimization of synbiotic yogurts with yacon pulp (Smallanthus sonchifolius) and assessment of the viability of lactic acid bacteria

The aim of this study was check the effects of sugar, yacon pulp and skimmed milk powder in the aroma, flavour, texture, appearance, overall impression and intent to purchase on synbiotic yogurts to optimize the formulation using Response Surface Methodology. The most accepted formulations were subjected to viability tests during 21 days by counting traditional and probiotic bacteria. Were constructed a complete 2 3 factorial design, totalling 17 experiments, and considered independent variables (percentage of ingredients) and dependent variables (sensory attributes). All attributes were graded using an acceptability assessment, for this balanced incomplete block was applied. The number of viable cells was determined using specific culture medium for each species. The percentage of yacon pulp had a pronounced negative influence on flavour, texture, appearance, overall impression and intent to purchase. Model predictions adjusted to the variables aroma, flavour, texture, appearance, overall impression and intent to purchase exhibited good predictive ability and hence could be used as tools for process control. Traditional bacterial strains and probiotic remained viable throughout the storage period. The counts of probiotic bacterial in the formulations were above 6 log CFU/g. The addition of Lactobacillus paracasei ssp. paracasei LBC 81 and yacon pulp to yogurt increased product acceptability.Keywords: response surface methodology; fructo-oligosaccharides; L. paracasei ssp. Paracasei LBC 81; sensory analysis.Practical Application: The innovations of this study are to develop a product with high fructooligosaccharides content originating from the yacon, largest source of fos of nature, and with great potential for cultivation in the Northeast of Brazil. The important points of this were using amounts of ingredients that would allow the acceptance of the product without cripple the growth of probiotic as well as maintain a high score of L. paracasei ssp. paracasei LBC 81 throughout the storage period, which is considered to be a challenge in food industry.
