How to store coffee so it doesn't lose its flavor? Here's a chemical engineer's trick

oglobo4 September 2026 at 17:00

Coffee begins to lose its sensory properties long before it is considered spoiled. The aroma when opening the package and the flavor of the first days after roasting do not last forever, due to the chemical changes that the beans undergo after roasting. The way coffee is stored directly influences how long it preserves its original characteristics.

A chemical engineer named Ana, known on social media as "Science with Ana," published a TikTok video explaining the phenomenon. According to her, during the roasting process, chemical reactions occur related to the compounds responsible for a large part of coffee's characteristic aroma and flavor.

However, the chemical process does not end when the roasting is complete. From that moment on, the coffee begins to gradually lose intensity. This does not necessarily mean the product has spoiled, but rather that its sensory properties may change over time.

Therefore, besides choosing a good coffee and preparing it correctly, proper storage is also essential to maintain the quality of the drink for longer.

Study explains how breathing can influence our decisions

A German study published in the journal Neuron revealed that slow breathing, with expiration longer than inspiration, can make people more likely to take financial risks. Researchers from the Free University of Berlin used magnetic resonance imaging and cardiac monitors on 41 healthy adults to investigate the effect of controlled breathing on the brain and decisions. Prolonged expiration increases the activity of the parasympathetic nervous system, known as "rest and digest," amplifying cerebral sensitivity to rewards and leading to greater acceptance of risky bets. The study suggests that simple breathing techniques can directly influence economic behavior and decision-making.

Scientists create molecule that eliminates aggressive lymphoma tumors in rats in just 11 days

Researchers at Stanford University, in the United States, developed a molecule capable of eliminating aggressive B-cell lymphomas in rats in just 11 days. The substance redirects a common protein in this type of lymphoma to activate programmed cell death. When administered twice a day, the treatment was able to completely eliminate the tumor in less than two weeks. Professor Gerald Crabtree, from Pathology and Developmental Biology, explained that the approach aims to fight cancer at its cause, eliminating its driving force and reprogramming it to induce self-destruction mechanisms of cells.

"With adequate treatment, most people with epilepsy can live a normal life"

Epilepsy is a chronic neurological disease that affects about 10 in every 1,000 inhabitants in Portugal, and can occur at any age, although it is more frequent in the first year of life and after 60-65 years. Diagnosis is clinical, complemented by electroencephalogram and magnetic resonance imaging, and first-line treatment is pharmacological, with about two-thirds of patients becoming seizure-free. In the event of a tonic-clonic seizure, one should remain calm, protect the person by avoiding dangerous objects, and never try to restrain movements or place anything in the mouth. The causes are varied, including brain lesions, genetic and metabolic factors, and remain unknown in up to half of cases. With adequate treatment, most people can live a normal life, although about 44% of Portuguese patients do not have regular medical follow-up.
