Summary: This review collects available data on the occurrence of Tropane alkaloids (TAs) in foods and provides the latest techniques for food sample preparation from 2015 to present. Cereals and related products, as well as teas and herbal teas, are the most extensively analyzed food categories. Solid-liquid extraction remains the most widely used technique for sample preparation, but other extraction and purification techniques are also being applied.

Summary: In 2019, Uganda experienced a series of food poisoning events and deaths due to the presence of Tropane alkaloids, atropine and scopolamine, in the Super Cereal. The investigation revealed that the alkaloids were present because Datura seeds were incorporated during production of the Super Cereal, with all outbreaks caused by a single batch of the product.

Summary: This study investigated the effects of ultrasound-assisted (UAE), microwave-assisted (MAE), and ultrasound-microwave-assisted (UMAE) methods on pectin extraction from industrial tomato waste. The best extraction conditions were determined based on a fuzzy analytical method, considering pectin yield, galacturonic acid, and lycopene content. The results showed that UAE conditions with pH 1.5 and solid liquid (SL) ratio 1:30 resulted in high pectin yield and lycopene content. MAE conditions with 300 W power for 10 min yielded high pectin yield and galacturonic acid content. Moreover, the combination of UAE and MAE (UMAE) further improved the pectin yield compared to individual methods. However, the FTIR spectra of the obtained pectins showed similar structures regardless of the extraction technique.

Summary: Datura, belonging to the Solanaceae family, is known for its narcotic and analgesic effects in ancient China. It has wide distribution worldwide but can be harmful due to its poisoning and hallucinogenic effects. This plant plays a magical role in seed germination, plant growth, and has good effects against plant diseases, insects, and weeds. Its main active components, tmpane alkaloids, have diverse therapeutic effects on various diseases in humans and are also widely used in agriculture for insect and disease control.

Summary: Datura species are known for their high concentration of tropane alkaloids, which can lead to poisoning when accidentally mixed with edible crops. Testing on frozen spinach and spinach-based infant food products found that some samples had levels close to the maximum limits set by the European Union. This highlights the global concern over the presence of these compounds in various commodities.

Summary: Tropane alkaloids are toxic secondary metabolites found in agricultural weeds, and the intake of food and feed contaminated with these alkaloids can lead to poisoning in humans and animals. This study investigated the transfer of tropane alkaloids into milk from dairy cows exposed to different dosages, and found that even at low dosage levels, these alkaloids could be detected in milk, indicating a potential risk for consumers.

Summary: Microwave-assisted synthetic pathway was used for the sustainable esterification of cellulose nanofibers (CNFs) using an aromatic amine compound. Nanofibers were isolated from unbleached and bleached eucalyptus pulp and their chemical composition, structural properties, morphology, and thermal properties were investigated.

Summary: There is an urgent need to develop new pectin extraction processes in order to address the limitations and harmful effects of the current commercial extraction process. Microwave-Assisted Extraction shows promise as a sustainable alternative for pectin extraction from various food wastes and agricultural residues. While the literature does not universally support the notion that microwave heating improves yield and processing time compared to conventional extraction, there is emerging evidence that it can provide advantages under certain conditions.

Summary: Recently, utilizing natural bioactive compounds for active ingredients in cosmetics has become a growing worldwide trend. In order to optimize the safety of natural ingredients, choosing an environmentally friendly extraction method also plays an important role. This study investigated an eco-friendly extraction technique for Dendropanax morbifera using microwave treatment, which resulted in higher yields and enhanced antioxidant properties of the extract. Moreover, the extract exhibited extraordinary antioxidant, anti-aging, and skin-whitening activities, indicating its potential as a cosmeceutical ingredient for comprehensive skin protection.

Summary: Microwave-assisted extraction (MAE) and conventional heating extraction (CHE) techniques were used for pectin extraction from watermelon rind. MAE showed higher efficiency compared to CHE, with the highest yield achieved at MAE-500 W and 5 min irradiation time (16.01 +/- 0.11%). Watermelon rind pectin was classified as low-methoxyl pectin with a degree of esterification of 30-45%. The pectin with the highest galacturonic acid content, water holding capacity (WHC), and gel stability was obtained from MAE at 100 and 500 W with irradiation times of 26 and 5 min, respectively. MAE-300 W gave the highest oil holding capacity (OHC), followed by CHE method.
