“…É descrito na literatura que a secagem natural e artificial da biomassa foliar de Piper hispidinervum levou a alteração na composição química de monoterpenos e sesquiterpenos do óleo essencial, demonstrando que a concentração de alguns constituintes diminuía enquanto de outros como, por exemplo, do safrol aumentava (Machado et al, 2013).…”

RESUMO Campomanesia adamantium é muito utilizada na medicina popular no tratamento de hipertensão, reumatismo e diabetes. Objetivou-se com o presente trabalho avaliar o rendimento, a composição química, e as atividades antimicrobiana e antioxidante do óleo essencial de folhas de C. adamantium submetidas a diferentes métodos e tempos de secagem. O delineamento utilizado foi inteiramente casualizado, com oito tratamentos e três repetições. O óleo essencial foi extraído por hidrodestilação das folhas e analisado por CG-EM. O tipo de secagem das folhas de C. adamantium influenciou no teor e na composição química do óleo essencial. Os constituintes espatulenol, óxido cariofileno e germacreno-B apresentaram maior concentração na maioria das procedências avaliadas. O óleo essencial das folhas de C. adamantium apresentou moderada atividade antibacteriana em relação a todos os micro-organismos testados. A atividade antioxidante se deu empregando-se o método de redução do radical estável DPPH, sendo observada fraca atividade antioxidante por meio do ensaio utilizado.

Drying kinetics of pineapple agro-industrial residues was studied using thin-layer of product at 40℃, 50℃, 60℃ and 70℃, and airflow rate of 1.5 m/s. The diffusion model was modified and fitted to experimental data of moisture ratio of pineapple residue to estimate the diffusion coefficient as function of temperature, and a good fitting of Arrhenius equation was obtained, with a variance explained of 99.98 %. Values of diffusion coefficients varied in the range from 4.82 × 10 −10 m 2 ⁄s to 11.17 × 10 −10 m 2 ⁄s, approximately. A modification was implemented in the Page's equation to include the diffusion effects explicitly, leading to a less empirical and simpler model to describe drying kinetics of pineapple residue. The model presented in this work proved to be adequate to predict drying ratio of pineapple residue, if the material layer thickness is 1.0 cm, under the drying conditions used.

“…One of the alternative processes that can be used to reduce passion fruit wastes is drying, which can be carried out using artificially moved air, followed by flour production, which can be used in the formulation of other various types of food (Di Domenico et al, 2017;Machado et al, 2013).…”

The use of waste has been the focus of attention of the agri-food sector, and a fruit with large amount of waste is the passion fruit. Its peel consists of albedo and flavedo, which can be used to manufacture flour, and some studies propose the need to remove the flavedo as well as to perform maceration. The objective of the present work was to study the drying process to produce flour from passion fruit albedo and whole peel, checking the influences of the flavedo removal and maceration steps, as well as the drying temperatures (70 and 80 ºC). Yield after drying was calculated and it was shown to be low. Page, Silva et alii, Henderson and Pabis and Logarithmic mathematical models were fitted to the experimental data using LAB Fit software. The statistical indicators used to identify the best fit were coefficient of determination (R2) and chi-square (χ2). The Page model was the one that fitted best to the data, showing the best statistical indicators. Also, it can also be highlighted that the sample composed of peel without maceration and dried at 70 ºC had the best results regarding the statistical indicators.
