AI Article Synopsis

  • Green coffee is rich in antioxidants and was processed to obtain a chlorogenic acid (CGA) enriched extract from Arabica and Robusta varieties.
  • Physicochemical qualities and bioactive compounds of the green coffee extract (GCE) were assessed, revealing significant amounts of phenolics and CGA.
  • The GCE was successfully encapsulated using spray drying with maltodextrin and skim milk, improving its stability and protection in simulated digestive environments, indicating potential use in food supplements and nutraceuticals.

Article Abstract

Green coffee is a prime source of antioxidants to functional food and nutraceuticals. Arabica and Robusta varieties were screened and decaffeinated using ethyl lactate and extracted with a polar solvent to obtain chlorogenic acid (CGA) enriched green coffee extract (GCE). The physicochemical qualities (moisture, pH, particle size, and color) and bioactive compounds (total phenolics, chlorogenic acid, and caffeine) of GCE were assessed. The GCE had 12.78 ± 2.1 mg GAE g phenolics and 10.98 mg g chlorogenic acid (CGA). To improve the stability of CGA, the GCE encapsulated by spray drying using maltodextrin (MD) and skim milk (SM) as coating agent individually and in combination. Physicochemical, antioxidant properties, and biofunctionalities of microparticles were evaluated. Highest encapsulation efficiency of GCE with maltodextrin (1:1) was 86%±3 with the smaller particle size (2.3 ± 0.1 µm). Under the simulated gastric juice and bile salts solution, microencapsulation provided significantly better protection compared to non-encapsulated GCE. MGE elicits use as adjuvant/supplements in food, fortified for nutraceuticals and pharmaceuticals.

Article Synopsis
  • The study focused on three coffee estates in New South Wales, aiming to enhance the flavor profiles of Australian coffee through different processing methods (wet fermented and non-fermented).
  • Researchers analyzed 33 volatile compounds in both green and roasted coffee beans, identifying various esters, alcohols, acids, and more, while also assessing sensory characteristics like appearance and flavor.
  • Findings indicated that wet fermentation improved certain desirable aromas and flavors in coffee, particularly enhancing notes associated with premium coffees, such as "black tea leaves" and "dark chocolate."

Post-fermented Pu-erh tea (PFPT) is a microbial fermented tea characterized by unique sensory attributes and multiple health benefits. is the dominant fungus involved in the fermentation process and plays a significant role in imparting the distinct characteristics of PFPT. To investigate the role of in the fermentation of Pu-erh tea, this study inoculated unsterilized sun-dried green tea with isolated from Pu-erh tea to enhance the fermentation process.

This study analyzed the phytochemical composition and functional properties of leaves and green beans from seven Arabica coffee cultivars. The total phenolic and flavonoid contents were measured using spectrophotometric methods, while caffeine, chlorogenic acid (CGA), and mangiferin levels were quantified via High-Performance Liquid Chromatography (HPLC). Volatile compounds were identified using Gas Chromatography-Mass Spectrometry (GC-MS).

Date processing industries generate substantial quantities of waste, including date seeds, which present disposal challenges and environmental concerns. Traditionally, date seed waste has been discarded through landfilling, open burning, or dumping, leading to soil, air, and water pollution. However, with increasing awareness of environmental sustainability and resource conservation, there is a growing interest in valorizing date seed waste using green extraction technologies and innovative food product development approaches for date seed valorization.
