“…Oligomate HP contained more than 50% GOS, and less than 50% monosaccharide and lactose. Prebiotic activities were determined by the method of Huebner et al (2007Huebner et al ( , 2008. Briefly, LAB and E. coli strains were inoculated into TY broth (tryptone 10 g/L, yeast extract 5.0 g/L, Tween 80 1.0 g/L, and L-cysteine HCl monohydrate 0.1 g/L, pH 6.8 ± 0.2) containing 0.2% (w/v) glucose, GOS (Oligomate HP), inulin and the lyophilized EPS, respectively, and incubated for 18 h at 37(C in consideration of the digestive tract environment in vivo.…”

Characteristics of an exopolysaccharide (EPS) produced by a mutant strain of Lactobacillus plantarum, strain 301102S, including yield from whey, monosaccharide analysis, and prebiotic activity, were investigated. The EPS production in whey was higher at 25℃ than at 30 and 37℃. The supplementation with yeast extract and glucose in whey gave a high EPS yield of 145 mg/L, and the EPS contained glucose and mannose (molar ratio, 1:2). Prebiotic activities of galactooligosaccharide, inulin and the EPS with 37 lactic acid bacteria strains were investigated, and prebiotic activity of the EPS was high with the parent strain. This suggests that the EPS produced in whey by the mutant strain is easier utilized by strain 301102 than the other strains, and the EPS produced by this strain is capable for use as a prebiotic.

“…For encapsulated samples from the UF-10, the multiplication of this bacteria was lower than the multiplication on glucose (p<0.05). Huebner et al (2008) mentioned that a good prebiotic substrate should have the ability to be selective and not fermented by intestinal pathogens. However, enterobacteria are predominant facultative anaerobic bacteria present in the ileum and colon, contributing significantly to the fermentation of FOS (Mitsuoka;Hidaka;Eida, 1987).…”

“…Among the strains tested, seven were able to grow in Raftiline LS (inulin), but the degradation of this substrate was low because a significant decrease of pH values was not observed. The hydrolysis of prebiotic carbohydrates often results in the formation of sucrose, glucose and fructose, which do not offer a selective stimulation of probiotic strains (Huebner et al, 2008).…”

“…They are considered prebiotics because selectively stimulate the proliferation and activity of bifidobacteria and lactobacilli in the gut (Lachman;Fernández;Orsák, 2003), providing an increased resistance to intestinal infections due to production of immunomodulating substances (Matusek et al, 2011;Vaz-Tostes et al, 2014). To maintain these properties, FOS should be chemically stable under heat and pH treatments (Huebner et al, 2008).…”

Characterization of powder from the permeate of yacon extract by ultrafiltration and dehydrated by spray drying

Yacon root is a functional food which contains antioxidants and prebiotics compounds. This study aimed to evaluate the physical, chemical and prebiotic characteristics of a yacon extract powder obtained by ultrafiltration (UF) with membranes of 10 and 30 kDa and encapsulation of the resulting permeate by spray drying. Drying air temperatures of 140 and 160 ºC and concentrations of gum arabic of 10 and 15% were tested. The samples had solubility values greater than 90% while the hygroscopicity decreased with increasing gum concentration and drying temperature. Electron microscopy showed a strong tendency to agglomeration of smaller particles around the larger ones, mainly at a temperature of 140 ºC. Regarding color, the parameter L* showed that drying at 160 ºC produced darker samples and the parameters a* and b* indicated that all samples were greenish yellow. The concentration of inulin decreased during drying, whereas the levels of glucose and fructose increased due to the thermolysis reaction, which led to degradation of inulin chains at drying temperature. The permeates and retentates from the UF membranes had prebiotic activity, while only the encapsulated product from UF-30 membrane, metabolized by Lactobacillus acidophilus LA-5 ® , presented activity scores without significant difference to that of glucose.Index terms: Encapsulation; inulin; prebiotic activity. RESUMOO yacon é uma raiz que contém compostos com atividade antioxidante e prebiótica. Este estudo teve como objetivo avaliar as características físicas, químicas e prebióticas das micropartículas de yacon encapsuladas por atomização. A partir do extrato do yacon foram obtidas as soluções de retido e permeado usando a separação por ultrafiltração (UF) com membranas de 10 e 30 kDa. O permeado foi misturado com goma arábica em concentrações de 10 e 15% e encapsulado por atomização a temperaturas de 140 e 160 °C. As micropartículas obtidas tiveram valores de solubilidade maiores que 90%, enquanto que a higroscopicidade diminuiu com o aumento da concentração de goma e da temperatura de secagem. A microscopia eletrônica mostrou uma forte tendência à aglomeração de partículas menores em torno das maiores, principalmente a 140 ºC. Em relação à cor, o parâmetro L* mostrou que a secagem a 160 ºC produziu amostras mais escuras, e os parâmetros a* e b* indicaram que todas as amostras tiveram coloração amarelo esverdeado. A concentração de inulina diminuiu durante a secagem, enquanto que os conteúdos de glicose e de frutose aumentaram devido às reações de termólise, o que levou à degradação das cadeias de inulina. As dispersões permeadas e retidas provenientes da separação de UF apresentaram atividade prebiótica, enquanto que somente o pó encapsulado proveniente da membrana de 30 kDa foi metabolizado pelo Lactobacillus acidophilus, apresentando escores de atividade sem diferença significativa em relação à da glicose.Termos para indexação: Encapsulação; inulina; atividade prebiótica.

“…De Gennaro et al (2000) and Huebner et al (2008) demonstrated that the sugars produced by partial hydrolysis of fructooligosaccharides could be involved in the Maillard reaction. Shorter chain inulins result, thus in even darker color as it possessed more low molecular weight fructans (Peressini and Sensidoni 2009).…”
