Chitosan coating with trans-cinnamaldehyde improves structural integrity and an...
Carvalho, Roberta Lopes; Cabral, Marilia Freitas; Germano, Thais Andrade; Carvalho, Winne Moita de; Brasil, Isabella Montenegro; Gallão, Maria IzabelThis study evaluated a 2% chitosan-based coating with 500 mg L 1 trans-cinnamaldehyde on quality attributes, pro- and anti-oxidative metabolism, and structural integrity of biological membranes and cell wall of fresh-cut melon (Cucumis melo var. Cantalupensis Naud.) stored for 20 days at 4 C. Coating improved (P < 0.05) samples’ firmness, colour, soluble solids, total vitamin C and carotenoid content for up to ...
Storage stability of acerola tropical fruit juice obtained by hot fill method
Sousa, Paulo Henrique Machado de; Freitas, Claisa Andréa Silva de; Maia, Geraldo Arraes; Brasil, Isabella Montenegro; Pinheiro, Anália MariaThe present work aimed to evaluate the chemical, physicochemical, sensorial and microbiological changes of non-sweetened glass-bottled acerola tropical fruit juice processed by hot fill method stored for 350 days in the same conditions as market (28 ± 2 C). At the end of the storage period, the juice presented good microbiological stability showing a reduction of the overall acceptance and appearance maintainin...
Isolation of total RNA from ripe and unripe soursop (Annona muricata L.) fruit
Brasil, Isabella Montenegro; Otoch, Maria de Lourdes Oliveira; Costa, José Hélio; Maia, Geraldo Arraes; Lima, Maria da Guia SilvaSoursop fruit tissue is known by its acidic pH and high levels of polysaccharides, polyphenolics and secondary metabolites. These conditions are recognized to interfere unfavorably with conventional methodologies for RNA isolation. We describe here a rapid and simple method for the isolation of total RNA from soursop fruit. RNA was extracted in less than 4 h through a combination of SDS/potassium acetate precip...
