Baked pretzels are a popular choice for a quick snack, easily identifiable by their classic twisted shape, glossy exterior, and small salt crystals sprinkled on top, making them a standout snack. However, it is not commonly known that compounds with fluorescent properties can be formed during their production. Carbon nanodots (CNDs) with an average size of 3.5 nm were isolated and identified in bakery products. This study delved into the formation of CNDs in pretzel production using a fractional factorial experimental design. The research revealed that the baking temperature had the most significant impact on the concentration of CNDs, followed by the concentration of NaOH in the immersion solution, and then the baking time. This study highlights the unique role of the NaOH immersion step, which is not typically present in bread-making processes, in facilitating the formation of CNDs. This discovery highlights the strong correlation between the formation of CNDs and the heat treatment process. Monitoring and controlling these factors is crucial for regulating the concentration of CNDs in pretzel production and understanding nanoparticle formation in processed foods for food safety.

A library of degradable poly(2-alkyl-2-oxazoline) analogues (dPOx) with different length of the alkyl substituents was characterized in detail by gradient elution liquid chromatography. The hydrophobicity increased with increased side chain length as confirmed by a hydrophobicity row, established by reversed-phase liquid chromatography. Those dPOx were cytocompatible and formed colloidally stable nanoparticle (NP) formulations with positive zeta potential.

Background: Almonds promote cardiometabolic health benefits; however, the ergogenic effect of almond supplementation on exercise recovery is less explored.
Objectives: We evaluated the impacts of raw, shelled, almonds on pain, muscle force production, and biochemical indices of muscle damage and inflammation during recovery from eccentrically biased exercise.
Methods: Using a randomized, crossover design, 26 healthy adults (37 ± 6 y) ran downhill (-10%) for 30 min at a heart rate corresponding to 65%-70% of maximal oxygen consumption followed by 3-d recovery periods after 8-wk adaptations to either ALMOND (2 oz/d) or isocaloric pretzel (CONTROL) feedings.
