| Yacon (Smallanthus sonchifolius (Poepp. and Endl.) H. Robinson) is a storage root originally grown in the Andean highlands. The fresh roots are perishable and quickly turn brown during handling and processing. Aiming to prolong shelf-life and to preserve the antioxidant compounds in yacon roots, 3 mm thick yacon slices were dried in a drying cabinet at 40, 50, and 60 ºC to a moisture content of 10-14%, and yacon strips were sun dried to a moisture content of 15-20%. The total phenolic content was measured by the Folin-Ciocalteu method, and the quenching capacity was evaluated by measuring the amount of DPPH (1,1-diphenyl-2-pidrylhydrazyl) inhibited in samples after drying and after 7 months of storage. The results showed that it is possible to preserve the... |

| Several unfruitful attempts to grow axenic shoot cultures of Smallanthus sonchifolius, also known as yacon, were made before healthy shoots grew in association with bacteria on half strength Murashigue and Skoog media supplemented with 2.2 µM benzylaminopurine. Twenty-one bacterial isolates were obtained from in vitro S. sonchifolius plantlets, eight of these isolates were identified as Flavimonas oryzihabitans, Curtobacterium pusillum, Sphingomonas paucimobilis, and Microbacterium imperiale. These microorganisms produced indole acetic acid (IAA) at amounts varying between 8.89 to 47.45 µg/mL, reason for being classified as plant growth promoting bacteria (PGPB). The results show that buds associated with bacteria cultured on sucrose free media produced... |

| O processo de desintegração de tubérculos de yacon promove a incorporação de oxigênio que favorece a oxidação de compostos fenólicos e decorrente contaminação do extrato aquoso com cores e odores objetáveis que prejudicam a sua utilização. Este estudo buscou verificar uma metodologia simplificada de extração dos carboidratos presentes nos tubérculos de yacon e efetuar uma primeira remoção de resíduos e compostos originários das cores e odores indesejáveis, utilizando processos de coagulação e precipitação, aplicando tecnologias de baixo custo. Após a etapa de trituração e remoção dos restos celulares, o extrato teve seu pH aumentado para 9,5 e a temperatura para 90ºC, seguido de sedimentação. A remoção deste precipitado foi realizada por filtração em papel... |

| ABSTRACT In this study, we examined the effects of lactic acid bacteria (LAB) inoculant and beet pulp (BP) on the quality of yacon (Smallanthus sonchifolius) residue silage. Yacon silage was prepared using a small-scale system of silage fermentation, and the treatments were as follows: control silage without any additive and silages with LAB inoculant Chikuso-1 (Lactobacillus plantarum, 5 mg/kg, fresh matter basis), BP (30% fresh matter basis), and LAB+BP. Silages were opened on days 3, 5, 7, 15, 30, and 60 of fermentation. The chemical composition, organic acid content, and in vitro ruminal digestion of the 60-day silage were determined. The pH of LAB-treated silage was lower than that of the silage without LAB. Furthermore, the LAB-treated silage... |

| The goal of this study was to develop a symbiotic lacteous drink, evaluate its physicochemical and sensory characteristics, and verify the viability of Lactobacillus acidophilus in the drink. The milk serum-based drink consisted of 50% milk serum containing 10% saccharose, 25% powdered milk, 15% yacon pulp, and cultures of Lactobacillus acidophilus-La 5E and Bifidobacterium bifidum BB12. It was stored for up to 21 days under refrigeration. The milk serum-based drink was analyzed for protein, ether extract, total dietary fiber, total frutans, carbohydrate content, color, pH, acidity, and contamination by coliforms, and Salmonella sp. Coliforms and Salmonella sp were not detected, and L. acidophilus and B. bifidum provided satisfactory probiotic counts up to... |

| The mode of action of specific probiotic bacteria and specific prebiotic ingredients and their effects on the intestinal microbiota modulation in humans and animals has been demonstrated in many studies. Intestine is characterized for harboring a complex and dynamic microbiota which, among others, has a function to protect the host from inflammatory disorders. A mature and balanced endogenous microbiota has also an important role in the maintenance of a desirable activity of the immune system. Deviations in gut microbiota composition, due to improper diet, radiotherapy, antibiotic treatment, stress and others, may lead to a variety of gastrointestinal disorders. To overcome an unbalanced microbiota, the consumption of specific probiotics and prebiotics has... |

| O yacon é tradicionalmente consumido como fruta fresca ou desidratado em diferentes graus. O interesse está focado tanto nas fibras solúveis como nas insolúveis (inulina). Nematoides do gênero Meloidogyne causam diminuição na produção e também fissuras e cicatrizes nas raízes, tornado-as sem valor comercial. Diante da importância que a cultura tem ganhado nos últimos anos, o objetivo do trabalho foi verifi car a efi ciência da aplicação de manipueira e do nematicida Carbofuran (Furadan 50G) em tratamento de solo, no controle de Meloidogyne sp., visando maior produtividade e qualidade final das raízes para a comercialização. O experimento foi conduzido nos canteiros experimentais do CERAT/UNESP/ Botucatu. Foram levantados doze canteiros de seis metros de... |
