Abstract

Introduction: Coffee silver skin (CSS) is a thin covering over green coffee seeds inside coffee cherry. It is a good source of bioactive compounds like chlorogenic acid and caffeine. It is produced as a by-product of the roasting process.

Objective: The goal of this study is to apply spray drying method to encapsulate 5-O-caffeoylquinic acid (chlorogenic acid) and caffeine extracted from CSS.

Methods: The main-plots for optimisation were feed solid concentration (2.5, 5, 10°Bx), and the sub-plots of the whole-plot were carrier material type (maltodextrin, modified starch, arabic gum) and inlet air temperature (130, 160, 190°C). Responses included were drying yield, chlorogenic acid concentration, caffeine content, Carr index, and solubility values.

Results: Suitable conditions were spray drying inlet temperature of 190°C, extract concentration of 10°Bx, and wall material composition [modified starch/arabic gum (MS:AG)] 10.5:9.5. As the feeding CSS extract concentration increased, the amount of chlorogenic acid and caffeine in the final powder increased, while the powder's flow characteristics improved.

Conclusions: The concentration stage might be used to produce free-flowing powdered particles with good bioactive retention for use in the food processing industry.

咖啡废副产品中绿原酸和咖啡因的封装方法设计。

简介咖啡银皮（CSS）是咖啡樱桃内绿色咖啡种子上的一层薄薄的覆盖物。它是绿原酸和咖啡因等生物活性化合物的良好来源。它是烘焙过程中产生的副产品：本研究的目的是采用喷雾干燥法封装从 CSS 中提取的 5-O-咖啡酰奎宁酸（绿原酸）和咖啡因：优化主图为进料固体浓度（2.5、5、10°Bx），全图的子图为载体材料类型（麦芽糊精、变性淀粉、阿拉伯胶）和进气温度（130、160、190°C）。反应包括干燥产量、绿原酸浓度、咖啡因含量、卡尔指数和溶解度值：合适的条件是喷雾干燥入口温度为 190°C，提取物浓度为 10°Bx，壁材成分[变性淀粉/阿拉伯树胶（MS:AG）]为 10.5:9.5。随着进料 CSS 提取物浓度的增加，最终粉末中绿原酸和咖啡因的含量也随之增加，同时粉末的流动性也得到改善：结论：浓缩阶段可用于生产具有良好生物活性的自由流动粉末颗粒，供食品加工业使用。

期刊介绍： Phytochemical Analysis is devoted to the publication of original articles concerning the development, improvement, validation and/or extension of application of analytical methodology in the plant sciences. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bio-screening), extraction, separation, purification, identification and quantification of compounds in plant biochemistry, plant cellular and molecular biology, plant biotechnology, the food sciences, agriculture and horticulture. The Journal publishes papers describing significant novelty in the analysis of whole plants (including algae), plant cells, tissues and organs, plant-derived extracts and plant products (including those which have been partially or completely refined for use in the food, agrochemical, pharmaceutical and related industries). All forms of physical, chemical, biochemical, spectroscopic, radiometric, electrometric, chromatographic, metabolomic and chemometric investigations of plant products (monomeric species as well as polymeric molecules such as nucleic acids, proteins, lipids and carbohydrates) are included within the remit of the Journal. Papers dealing with novel methods relating to areas such as data handling/ data mining in plant sciences will also be welcomed.
