Encapsulation of Chasteberry ( L.) Extract by Spray-Drying Followed by Spray-Chilling for Its Application in Dark Chocolate.

Chasteberry extract offers considerable phytotherapeutic benefits, particularly in alleviating premenstrual syndrome (PMS) symptoms. However, its hydroalcoholic nature leads to a bitter taste and a burning sensation, presenting challenges for direct consumption or incorporation into new food products. This study aimed to address these issues by encapsulating concentrated chasteberry extract using spray-drying with Arabic gum, followed by spray-chilling with vegetable fat as carriers.

Nitrogen forms and concentration influence the impact of titanium dioxide nanoparticles on the biomass and antioxidant enzyme activities of Microcystis aeruginosa.

Nanoparticles (NPs) are becoming more widely produced, used, and released into the aquatic environment. In aquatic ecosystems, these NPs affect different populations of photosynthesizing organisms, such as cyanobacteria. This study aimed to evaluate the effects of titanium dioxide (TiO) NPs (48 mg l) combined with low (0.

Combination of Spray-Chilling and Spray-Drying Techniques to Protect Carotenoid-Rich Extracts from Pumpkin () Byproducts, Aiming at the Production of a Powdered Natural Food Dye.

Reducing waste, using byproducts, and natural food additives are important sustainability trends. In this context, the aim of this study was to produce and evaluate a natural food dye, extracted from pumpkin byproducts, powdered and protected by spray-chilling (SC) and a combination of spray-drying and spray-chilling techniques (SDC). The extract was obtained using ethanol as solvent; vegetable fat and gum Arabic were used as carriers.

Encapsulation of Rich-Carotenoids Extract from Guaraná () Byproduct by a Combination of Spray Drying and Spray Chilling.

Guaraná byproducts are rich in carotenoids, featuring strong antioxidant capacity and health-promoting benefits. However, these compounds are highly susceptible to oxidation and isomerization, which limits their applications in foods. This research aimed to encapsulate the carotenoid-rich extract from reddish guaraná peels by spray drying (SD), chilling (SC), and their combination (SDC) using gum arabic and vegetable fat as carriers.

Quantitative Detection of Beef Contamination in Cooked Meat Products by ELISA.

Concerns about the contamination of meat products with undeclared meats, and new regulations for the declaration of meat adulterants have established the need for a rapid test to detect beef adulteration to 0.1% sensitivity. To address this need, Microbiologique, Inc.

Quantitative Detection of Chicken and Turkey Contamination in Cooked Meat Products by ELISA.

: Concerns about the contamination of meat products with undeclared meats and new regulations for the declaration of meat adulterants have established the need for a rapid test to detect chicken and turkey adulteration. : To address this need, Microbiologique, Inc. has developed an ELISA that can quantify the presence of chicken and turkey down to 0.

Quantitative Detection of Horse Contamination in Cooked Meat Products by ELISA.

Concerns about the contamination of meat products with horse meat and new regulations for the declaration of meat adulterants have highlighted the need for a rapid test to detect horse meat adulteration. To address this need, Microbiologique, Inc., has developed a sandwich ELISA that can quantify the presence of horse meat down to 0.

Quantitative Detection of Pork Contamination in Cooked Meat Products by ELISA.

Recent news of many cases of adulteration of meats with pork has bolstered the need for a way to detect and quantify the unwanted contamination of pork in other meats. To address this need, Microbiologique, Inc. has produced a sandwich ELISA assay that can rapidly quantify the presence of pork in cooked horse, beef, chicken, goat, and lamb meats.

NDI and DAN DNA: nucleic acid-directed assembly of NDI and DAN.

Two novel DNA base surrogate phosphoramidites 1 and 2, based upon relatively electron-rich 1,5-dialkoxynaphthalene (DAN) and relatively electron-deficient 1,4,5,8-naphthalenetetracarboxylic diimide (NDI), respectively, were designed, synthesized, and incorporated into DNA oligonucleotide strands. The DAN and NDI artificial DNA bases were inserted within a three-base-pair region within the interior of a 12-mer oligonucleotide duplex in various sequential arrangements and investigated with CD spectroscopy and UV melting curve analysis. The CD spectra of the modified duplexes indicated B-form DNA topology.

Double jeopardy: two possible causes of sudden death in a previously healthy man.

A case of the simultaneous occurrence of two rare causes of sudden death is reported. A previously healthy man was shown to have anomalous coronary circulation, with the left main coronary artery coursing between the great arteries, and Brugada syndrome raising the possibility of an association between these findings.

Characterization of a branch of the phylogenetic tree.

We use a combination of analytic models and computer simulations to gain insight into the dynamics of evolution. Our results suggest that certain interesting phenomena should eventually emerge from the fossil record. For example, there should be a "tortoise and hare effect": those genera with the smallest species death rate are likely to survive much longer than genera with large species birth and death rates.
