Inhibition of tuber sprouting in potato cultivars Asterix and Challenger by 1.4...
Mendonça Neto,Abelardo Barreto de; Pereira,Ariana Mota; Guimarães,Maria Eduarda da Silva; Gonçalves,Dreice Nascimento; Soares,Luciana GomesABSTRACT: The aim of this study was to verify the efficiency of 1,4-dimethylnapthalene in suppressing sprouting and the consequent maintenance of the quality of potato tubers of Asterix and Challenger cultivars, at different temperatures and storage regimes. Six treatments were tested, with and without 1.4-DNM, at temperatures of 8 ° C and 20 ° C. Assessments were made at 0, 45, 90, 135 and 180 days after appli...
Ideal temperature and storage period for commercial potato cultivars selected f...
Cruz,Renata Ranielly Pedroza; Pereira,Ariana Mota; Ribeiro,Wellington Souto; Freire,Ana Izabella; Costa,Franciscleudo Bezerra da; Zanuncio,José ColaABSTRACT: Potatoes for industrial processing must have high dry matter, low sugar and free from damage or disease. The objective was to determine the ideal temperature and storage period of commercial cultivars for frying. Tubers of Asterix and Cronos cultivars were stored in a cold chamber (Gallant CMC4 Premium) inside plastic boxes at 6 and 8 °C with 85 to 95% humidity for 180 days. Accumulated mass loss (PMA...
Storage of markies cultivar potatoes for prossessing
Petrucci,Kharen Priscilla de Oliveira Salomão; Pereira,Ariana Mota; Moreira,Marialva Alvarenga; Cecon,Paulo Roberto; Finger,Fernando LuizABSTRACT The refrigerated induce the sweetening of the potato, which results in the dark color. The objective of this study was to determine the temperature and shelf life of Markies potato tubers under refrigerated storage for the processing of French fries. The levels of total soluble sugar (TSS), reducing sugars (RS), peroxidase (POD) and polyphenoloxidase (PPO) activity, color after frying and start of spro...
Use of methyl jasmonate in bird of paradise
Pereira,Ariana Mota; Gomes,Mateus de Paula; Gonçalves,Dreice Nascimento; Guimarães,Maria Eduarda da Silva; Freire,Ana Izabella; Finger,Fernando LuizABSTRACT The MeJA has been shown to be promising in reducing the damages caused by cold and maintaining the quality in several products. Nevertheless, few studies are conducted with flowers and there are no studies of its use in bird of paradise. The objective of this study was to determine whether the pulsing application with MeJA submitted to cold storage promotes physiological changes of the bird of paradise...
Amylose content and micromorphology of popcorn progenies with different popping...
Freire,Ana Izabella; Castro,Elisa de Melo; Pereira,Ariana Mota; Cruz,Renata Ranielly Pedroza; Souza,Filipe Bittencourt Machado deABSTRACT: Popcorn (Zea mays var. everta) has a higher commercial value than common maize, in addition to being a popular food among consumers. Today, there is a constant search for cultivars with superior performance for several traits of interest in the case of popcorn, yield and popping expansion. On this basis, this project proposes to characterize progenies of popcorn with different values of expansion ca...
Vase life and rehydration capacity of dry-stored gladiolus flowers at low tempe...
Costa,Lucas Cavalcante da; Araújo,Fernanda Ferreira de; Santos,Mirelle Nayana de Sousa; Lima,Paula Cristina Carvalho; Pereira,Ariana MotaABSTRACT: Normally, it is not recommended the conditioning of gladiolus stems in water during storage or transport. Hydration of petals may accelerate flower opening, even at a low temperature, which compromises quality at marketing moment. However, for this species, neither the effect of prolonged dry cold storage nor its behavior when transferred to water at room temperature has been evaluated. The present st...
Action of abscisic and gibberellic acids on senescence of cut gladiolus flowers
Costa,Lucas Cavalcante da; Araujo,Fernanda Ferreira de; Lima,Paula Cristina Carvalho; Pereira,Ariana Mota; Finger,Fernando LuizABSTRACT The gladiolus flower is classified as insensitive to ethylene. Thus, the signals that initiate senescence are poorly understood. This study evaluated the role of abscisic and gibberellic acids on postharvest senescence of 3 cultivars of cut gladiolus flowers (Gladiolus grandiflora Hort.). Stalks were harvested and placed in test tube containing 100 mL distilled water or an aqueous solution of abscisic ...
Drying time and post-harvest quality of onion bulbs submitted to artificial curing
Cardoso,Deise Silva Castro Pimentel; Pereira,Ariana Mota; Correia,Teresa Drummond; Finger,Fernando LuizABSTRACT After harvest, onion bulbs are submitted to curing, whose objective is to provide loss of moisture in leaves and drying of outer layers (peel) of bulbs, reaching attractive external coloration and reduction in the intensity of rottenness. The objective of this study was to use an air treatment unit (ATU) - known as heat pump - as an alternative drying method, and to evaluate drying time and preservatio...
Carboidratos e carotenoides totais em duas variedades de mangarito
Ferreira,Ana Paula Sato; Puiatti,Mário; Pereira,Ariana Mota; Cecon,Paulo Roberto; Bhering,Aline da Silva; Mendes,Teresa Drummond CorreiaO objetivo deste trabalho foi avaliar a composição de carboidratos e carotenoides em rizomas mãe e filhos das variedades de mangarito (Xanthosoma riedelianum) pequeno e gigante. Amostras dos rizomas coletadas ao longo do ciclo cultural e após 90 dias de armazenamento foram avaliadas quanto aos teores de carboidratos e carotenoides totais. Os rizomas apresentaram aumento no teor de carboidratos, e o rizoma-mãe d...
