Abstract

The aim of this study was to evaluate the effect of controlled atmosphere storage on quality of native and cultivated yerba mate produced in Arvorezinha (RS) and São Mateus do Sul (PR) after 0, 3, 6 and 12 months of storage under ambient conditions, low oxygen (1.0 kPa) and high carbon dioxide (3.0 kPa) partial pressures. Total chlorophyll concentration reduced over the storage period regardless of the atmosphere condition, form of cultivation and production region. Total carotenoids, regardless of the form and place of cultivation, decreased until three months of storage under 1.0 kPa O2. Although, the O2 reduction to 1.0 kPa maintains greener color and higher chlorophyll concentration after 12 months of storage. High carbon dioxide partial pressures (3.0 kPa) in the storage chamber increases the polyphenol concentration until six months of storage. The raw material originated from São Mateus do Sul (PR) has higher chlorophyll concentration and greener color, resulting in greater storage potential.

低氧高二氧化碳对马黛茶品质保鲜的孤立效应

本研究的目的是评价在低氧(1.0 kPa)和高二氧化碳(3.0 kPa)分压环境条件下，在Arvorezinha (RS)和 o Mateus do Sul (PR)中生产的天然和人工马德茶在0、3、6和12个月后对质量的影响。无论大气条件、栽培形式和产地如何，总叶绿素浓度在贮藏期内均呈下降趋势。在1.0 kPa O2条件下，在贮存3个月前，无论何种栽培方式和栽培地点，类胡萝卜素总量均呈下降趋势。但当O2还原到1.0 kPa时，贮藏12个月后仍能保持较绿的颜色和较高的叶绿素浓度。存储室内的高二氧化碳分压(3.0 kPa)使多酚浓度升高，直至存储6个月。产自南马柳丝(o Mateus do Sul, PR)的原料叶绿素浓度较高，颜色更绿，具有更大的储存潜力。
