Application methods of biostimulants affect the production and postharvest cons...
Góes, Glêidson Bezerra de; Vilvert, João Claudio; Araújo, Nícolas Oliveira de; Medeiros, José Francismar de; Aroucha, Edna Maria MendesWorldwide, Brazil holds the fifth position in melon fruits exportation, further expanding its products to provide for the growing demand. This expansion is the result of the development and application of new technologies, including the management of the use of biostimulants. However, for melon crops, the information in the literature on the use of biostimulants remains limited to the effects of different doses...
Biodegradable films of gelatin incorporated with bentonite clay ionically modified
Garrido, Murillo Alves; Leite, Ricardo Henrique de Lima; Aroucha, Edna Maria Mendes; Santos, Franciso Klebson GomesBiofilms are biodegradable and/or edible films made from biopolymers. The application of biofilms as packaging is directly related to its characteristics, and to their interactions with the product and the environment. Proteins are promising materials, due to the wide range of functional properties. Gelatine is an attractive biomaterial, due to its large production and low cost. However, gelatine has limitation...
Performance of ‘Galia’ melon grown under different soil cation ratios
Paiva, Cristiane Alves de; Medeiros, José Francismar de; Almeida, José Gustavo Lima de; Aroucha, Edna Maria MendesThe northeast region of Brazil stands out in the production and export of melon. In this region, where this crop is mostly grown, part of the soil is of limestone origin, as is the irrigation water used. Over successive cultivations, these conditions can lead to soil alkalinization due to the accumulation of basic cations of the exchange complex, such as Ca, Mg, K and Na, in soils that are already rich in bases...
Potassium nutrition as a strategy to mitigate salt stress in melon grown under ...
Oliveira, Giordanio Bruno Silva; Oliveira, Francisco de Assis de; Santos, Sandy Thomaz dos; Oliveira, Mychelle Karla Teixeira deThe use of saline water is one of the major challenges of agriculture, as it can cause nutritional imbalances and thus reduce crop yield. This study proposes to examine the efficiency of potassium nutrition as a salt stress-mitigating agent in melon grown in a protected environment. The experiment was laid out in a randomized-block design with ten treatments in a 2 × 4 factorial arrangement represented by two m...
Edible films from polyneric blends of chitosan, pectin and cassava starch
Costa, Tamara Lorena; Leite, Ricardo Henrique Lima; Aroucha, Edna Maria Mendes; Santos, Francisco Klebson GomesNon-biodegradable polymeric materials have become a problem due to their long degradation time in the environment. Thus, studies show interest in the development of polymeric films and mixtures of these as functional materials in the most diverse areas, especially due to their characteristics such as biocompatibility, biodegradability and non-toxicity. Therefore, the objective was to develop and characterize ed...
Quality of Apis mellifera honey after being used in the feeding of jandaira sti...
Tôrres, Wedson de Lima; Vilvert, João Claudio; Carvalho, Airton Torres; Leite, Ricardo Henrique de Lima; Santos, Francisco Klebson Gomes dosThe aim of this study was to evaluate the physicochemical quality and bioactive compounds of Apis mellifera honey as well as the alterations in the quality of A. mellifera honey after being used in the feeding of Melipona subnitida colonies. A. mellifera honeys were collected in apiaries, homogenised and used as feed for M. subnitida bees for 30 days. Every five days, honey samples were collected and evaluated ...
Qualidade pós-colheita da cajarana em diferentes estádios de maturação durante ...
Souza, Aline Ellen Duarte de; Aroucha, Edna Maria Mendes; Souza, Clarice Sales Moraes de; Ferreira, Rafaella Martins de AraújoEste trabalho objetivou avaliar a qualidade pós-colheita da cajarana em diferentes estádios de maturação, durante armazenamento refrigerado. Os frutos foram coletados no município de Mossoró/RN, em quatro estádios de maturação (I: frutos verdes, com algumas protuberâncias; II: frutos com 75% da casca verde; III: frutos com 50% da casca verde; IV: frutos com 25% de casca verde) e transportados para o Laboratório...
Avaliação da qualidade físico-química de polpas de frutas congeladas na cidade ...
Oliveira, Thiago Azevedo de; Leite, Ricardo Henrique de Lima; Aroucha, Edna Maria Mendes; Freitas, Thaizy Gardênia Gurgel deO presente trabalho teve como objetivo avaliar a qualidade físico química de polpas de fruta congeladas comercializadas na cidade de Mossoró/RN, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define os Padrões de Qualidade e Identidade (PIQ´s) estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram realizadas análises físico-química...

Avaliação de coberturas comestíveis compostas por quitosana e argila no revesti...
Costa, Tamara Lorena Eufrazio da; oliveira, Thiago azevedo de; Santos, Francisco Klebson Gomes dos; Aroucha, Edna Maria MendesO tomate é um fruto muito perecível e com curta vida de prateleira, demonstrando uma necessidade do desenvolvimento de tecnologias que reduzam estas perdas. Na indústria de alimentos, a quitosana se destaca por ser de origem natural, renovável, biodegradável, atóxico e propriedade de formação de filme. A argila possibilita uma maior aderência do filme na superfície do fruto, e é utilizada para fechar vacâncias ...
