Embalagens e armazenamento de plantas medicinais

Abstract

O reconhecimento das propriedades terapêuticas é tão antigo quanto a ocorrência dos humanos na Terra. Independentemente da finalidade do uso de plantas medicinais, não há dúvida de que tem havido um aumento na demanda por métodos naturais, representando um grande desafio para produtores e pesquisadores, no que diz respeito à padronização e controle de qualidade da matéria-prima, para garantir a qualidade das espécies oferecidas aos consumidores e à indústria farmacêutica. Apesar do aumento do consumo e consequente expansão do mercado de plantas medicinais, poucos são os estudos específicos envolvendo a utilização de técnicas de embalagem e armazenamento para esse tipo de produto. Diante do exposto, este estudo levantou conceitos envolvendo embalagens, bem como características de alguns polímeros comumente utilizados no armazenamento de produtos de origem vegetal, técnicas e equipamentos utilizados na embalagem de produtos alimentícios e trabalhos envolvendo o uso de atmosfera modificada na área de armazenamento de plantas medicinais.

Physicochemical Quality Evaluation of Fresh-Cut Rosemary (Rosmarinus officinalis L.) Packed and Stored in Biodеgradаblе Film

“…Similar mass losses were reported by researchers Lee and Chandra (2018) -at the end of a 16-day storage period at 10 °C in dark room total fresh biomass loss for lettuce in Anti-Fog-PP and Non-PPP were 2.2% and 2.7% respectively. Scientists from Brazil (Lisboa et al, 2022) highlighted that the moisture loss can be defined as the general factor of fresh-cut rosemary's weight loss during storage. As the reason, different properties of packaging materials in the case of water vapour barrier were mentioned.…”

“…Stored in non-appropriate packaging, aromatic and medicinal plants can be affected by permeating gases which is why losses of main ingredients can be observed. According to Brazilian scientists (Lisboa et al, 2022), packaging materials can minimise respiration of fresh aromatic and medicinal plants. A good gas barrier dissolved in the product and/or around it, reduces the process of respiration as well as the metabolic processes during the herbs' storage.…”

“…Food scientists have proven that observations prove that both conventional breathable and biodegradable packaging films with an appropriate O 2 transmission rate play an important role in development of equilibrium modified atmosphere and in quality of packages of fresh shredded carrots during storage (Augspole et al, 2019). Researchers Lisboa et al (2022) reported that inside of the packaging, the permeation of oxygen to the environment because of oxidation influences the alteration of the colour and flavour of many medicinal species. In the case of carbon dioxide, the permeation of water vapour from packaging to the environment influences the changes in respiration as well as the loss of carbonation.…”
