“…Although basil occurs throughout the year, post-harvest treatments are necessary to control microbiological and biochemical changes and prolong its shelf life. Drying is a preservation method frequently used for the dehydration of leaves, and the literature shows that it has been used as a pre-treatment of basil leaves, to obtain essential oil [ 7 ] and for the infusion preparation [ 8 ].…”

This study evaluated the effect of convective drying on the degradation of color and phenolic compounds of purple basil (Ocimum basilicum L.) leaves, and the hygroscopic behavior of dried leaves. The fresh leaves underwent drying at 40 °C, 50 °C, 60 °C, and 70 °C. Degradation of chlorophyll, flavonoids, and phenolic compounds were evaluated during drying and the hygroscopicity was evaluated through the moisture sorption isotherms. The drying mathematical modeling and the moisture sorption data were performed. The effective diffusivity for the drying increased from 4.93 × 10−10 m2/s at 40 °C to 18.96 × 10−10 m2/s at 70 °C, and the activation energy value (39.30 kJ/mol) showed that the leaves present temperature sensibility. The leaves dried at 40 °C had less degradation of phenolic compounds and color variation, but the drying process was too slow for practical purposes. Modified Page, Diffusion Approximation, and Verna models had excellent accuracy in drying kinetics. The isotherms showed that, in environments with relative humidity above 50%, the purple basil leaves are more susceptible to water gain, and at 8.83 g H2O/100 g db moisture, it guarantees the microbiological stability of the dried leaves. The Oswin model was the most suitable for estimating the moisture sorption isotherms of the dried leaves.

“…Variações químicas e de rendimento existem entre os OEs e são decorrentes de características intrínsecas da espécie vegetal, variabilidade genética, local de coleta, condições edafoclimáticas, assim como dos métodos de extração utilizados (ZOTTI-SPEROTTO et al, 2020), essa complexidade resulta em perfis químicos distintos, que, por sua vez, impactam suas propriedades e aplicações.…”

“…Como discutido acima, a composição química dos OEs pode variar dependendo de fatores como espécie de planta, localização geográfica e método de extração. A natureza volátil, fotodegradável, termolábil e baixa solubilidade em água desses compostos dificulta sua incorporação em formulações aquosas (ZOTTI-SPEROTTO et al, 2020;ASSADPOUR et al, 2023). Além disso, a suscetibilidade dos compostos aos processos de degradação e oxidação representa uma limitação adicional, visto que em campo, as condições não são as mesmas que as testadas em laboratórios, o que pode reduzir a sua eficácia ao longo do tempo (ASSADPOUR et al, 2023;GUPTA et al, 2023).…”

“…Esses compostos, classificados como metabólitos primários, constituem os blocos de construção essenciais para o funcionamento básico e a sobrevivência das plantas, além de servirem como base para a formação dos metabólitos secundários. Estes últimos, representando menos de 5% da matéria seca vegetal, estão sujeitos a variações quantitativas e qualitativas, sendo influenciados pela disposição genética da planta e suas interações ambientais (HANIF et al, 2019;ZOTTI-SPEROTTO et al, 2020).…”

“…Different drying methods can be found, such as convection drying [4], solar drying [11], infrared freeze drying [1-3, 12,13], IR drying [14], microwave combined drying [15,16], and ultrasonic combined drying [17,18]. However, no publications exhibit drying methods according to energy costs, production scale, operating principles, applications, wind speed, price, and product quality.…”

Drying medicinal herbs is one of the necessary methods to maintain a stable quality of medicinal herbs. Currently, there are many methods of drying medicinal herbs, such as sun drying, freeze drying, infrared drying, ultrasonic drying, microwave drying, and convection drying. Each method produces different quality medicinal materials with advantages and disadvantages in productivity, product quality, energy costs, and applications. Therefore, the paper focuses on other methods of drying agricultural medicinal herbs with the above issues, such as a basis for scientists and manufacturing enterprises to choose appropriate drying methods.
