Mid‐Infrared Spectroscopy and Machine Learning for Chlorogenic Acid Quantification in Coffee

Chemie Ingenieur Technik, EarlyView.
Chlorogenic acid (CGA) concentration in coffee was predicted using mid‐infrared (MIR) spectroscopy and a machine learning approach. Forty‐four roasting stages (140–220 °C) plus a green coffee control were analyzed. A multilayer perceptron regressor, trained on preprocessed MIR data, outperformed traditional peak analysis, enabling accurate and ...

Multiplication of embryogenic calli in Coffea arabica L. [PDF]

Acta Scientiarum. Agronomy, 2012
The goal of this project was to evaluate the embryogenic callus induction of two Coffea arabica clones selected for their characteristics of rust resistance and high yield, as well as to compare their multiplication in two different media under both solid and liquid cultivation conditions. The protocol described by Teixeira et al.

Physical and organoleptic characteristics of Limmu coffee landraces, southwestern Ethiopia

JSFA reports, EarlyView.
Abstract Background Coffee (Coffea arabica L.) is one of the world's most valuable agricultural commodities, with Ethiopia recognized for producing high‐quality Arabica coffee. Limmu landrace coffees are prized for their distinctive flavor profiles; however, systematic evaluation of their raw and cup quality traits remains limited.

Exploring portable NIR spectroscopy in transmittance and reflectance modes for the authentication of Brazilian coffees with geographical indications

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographical indications (GIs) certify the link between coffee origin and quality, enabling premium pricing and protecting producers. However, the high market value of GI coffees increases their vulnerability to fraud, underscoring the need for reliable and practical authentication methods.

Electrospun encapsulation of grape pomace extract: in vitro antioxidant, anti‐inflammatory, and antihyperglycemic properties

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The escalating prevalence of lifestyle‐ and aged‐related conditions, including diabetes, chronic inflammation, and cardiovascular disorders, underscores the urgent need for natural therapies. Such alternatives should offer reduced side effects compared to conventional pharmaceuticals while playing a proactive role in disease ...

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...
