“…The maintenance of firmness in the fruit of the HPMC+20% BW treatment, is probably related to the reduced O 2 and CO 2 flux. This change slows the speed of fruit ripening and senescence, because reduced ethylene biosynthesis results in reduced respiratory activity, acid consumption, coloration changes, membrane degradation processes, and loss of firmness (Reges et al, 2018).…”

“…The coatings act as a semi-permeable barrier to water vapor movement, due to surface transpiration elevating the diffusion of solutes. Consequently, this phenomenon results in mass loss that occurs by the outflow of water vapor to the surrounding medium due to the water vapor pressure difference between the atmosphere and the fruit surface (Reges et al, 2018;Formiga et al, 2019). The beeswax A.…”

“…The increase in SS is related to the conversion of starch into soluble sugars. The employment of barriers, such as coatings, forms a modified atmosphere that results in increased CO 2 and a reduced O 2 , which can lead to decreased carbohydrate metabolism and delayed starch conversion (Reges et al, 2018;Formiga et al, 2019).…”

“…Although the fruits are considered tasty, production and marketing are still limited due to high perishability stemming from post-harvest metabolic processes (Reges et al, 2018;Ambika et al, 2019). These exhibit restrictions as to their distribution to foreign markets, these being accelerated ripening, making them very soft, making them difficult to handle, and extremely succinct preservation.…”

The pinecone (Annona squamosa L.) is an Annonaceae that provides much appreciated fruit. However, these fruits have a limited shelf life due to their intense metabolic activity after harvest. The application of post-harvest conservation techniques, such as edible coatings, has been used to minimize the deleterious effects after the harvest of fruits, such as pinecone. The objective of this work was to evaluate the effects of coatings based on hydroxypropyl methyl cellulose (HPMC) and beeswax (BW) on the quality of pinecones stored at room temperature of 20 °C, from the local market in the city of Juazeiro, BA, Brazil. The fruits were selected for the absence of damage and sanitized by immersion in chlorinated water. The coatings were prepared by diluting the HPMC solution in deionized water at 90 °C under stirring, followed by cooling and addition of BW in different proportions, stearic acid, and glycerol. The coatings were applied to the surface of the fruits by immersion in the film-forming solution and dried at room temperature of 20 °C. The HPMC-based coatings associated with BW maintained the firmness and the whitening index of the pulp of the cones for a longer time, as well as led to lower activity of the enzymes polyphenoloxidase (PPO) and peroxidase (POD) during storage.

“…Ao final do armazenamento os frutos envoltos em embalagem plástica de PVC demonstraram as menores contagens de rachaduras quando comparados aos frutos controle e envoltos em fécula de mandioca a 3%. Reges et al (2018) avaliando a qualidade pós-colheita de ata (Annona squamosa L.) submetida ao atraso na retirada do filme de PVC observaram que os frutos do tratamento controle apresentaram menor incidência de rachaduras associado ao fato de que a embalagem retardou o amadurecimento dos frutos sem comprometer a qualidade. Segundo os autores o filme de PVC retardou a perda de massa, diminuiu a acidez titulável e contribuiu positivamente para a aparência externa e vida pós-colheita de 6 dias.…”

Atemoia é um fruto muito perecível que necessita de cuidados durante o armazenamento. Assim, esta pesquisa teve como objetivo avaliar a qualidade pós-colheita de atemoias ‘Gefner’ armazenadas sob atmosfera modificada. Os frutos foram colhidos em maturidade fisiológica na empresa Kabocla na Chapada do Apodi e transportados para o IFCE Campus Limoeiro do Norte (CE), onde foram selecionados e sanitizados. Posteriormente, foram aplicados os tratamentos: (T1) Controle; (T2) Policloreto de vinila- PVC em tempo parcial; (T3) PVC em tempo total e (T4) fécula de mandioca a 3 %. Os frutos foram armazenados em câmara fria a 15 ± 4°C e umidade relativa 85 ± 4%. Utilizou-se delineamento inteiramente casualizado em esquema fatorial 4 x 6, em que o primeiro fator constou dos tipos de recobrimentos e o segundo dos tempos de armazenamento (0, 3, 6, 9, 12 e 15). A cada três dias foram analisadas: perda de massa fresca, firmeza da polpa, aparência externa, cor da casca, índice de rachadura, acidez titulável, pH, sólidos solúveis, amido, açúcares totais, ratio e vitamina C. Resultados expressivos foram observados para perda de massa dos frutos recobertos com fécula de mandioca a 3% e controle com 5,93 e 7,12%, respectivamente. Ao longo do armazenamento todos os frutos apresentaram perda de firmeza e aumento do índice de rachaduras. A fécula de mandioca a 3% ocasionou perda de qualidade externa e atrasou mudanças de coloração da casca juntamente com os outros recobrimentos, atrasando o início das rachaduras. Os recobrimentos proporcionaram vida útil de 9 dias.

The high rate of perishability of fruits such as cagaita (Eugenia dysenterica DC.), seriguela (Spondias purpurea L.), mangaba (Hancornia speciosa Gomes) and pitomba (Talisia esculenta Radlk.) makes it necessary to develop adequate conservation techniques to increase post-harvest shelf life. The aim of this research was to evaluate the post-harvest quality attributes of cagaita, seriguela, mangaba and pitomba fruits stored in different types of packaging during certain periods. The treatments were defined by the combination of three types of packaging (low-density polyethylene (LDPE), polyvinyl chloride (PVC) and without packaging) and seven storage periods. Total soluble solids, titratable acidity, hydrogen potential (pH), fruit firmness and loss of fresh mass were analyzed. Fruits packaged with LDPE presented the lowest values of fresh mass loss: 2.7, 2.3, 4.2 and 1.1% for cagaita, seriguela, mangaba and pitomba, respectively. Furthermore, LPDE packaging maintained the quality attributes in all fruits analyzed. PVC packaging was more efficient in maintaining fruit firmness, with average values of 0.03 N. Atmospheric modification techniques, such as LDPE and PVC packaging, make it possible to reduce metabolic activity, ensuring better post-harvest quality and increasing the storage period of fruits that occur in the semiarid region of Minas Gerais.
