This study investigated the effect of liquid nitrogen ball-milled mechanochemical treatment on multiscale structure and physicochemical properties of starches with typically selected A (rice starch, ReS), B (potato starch, PtS) and C (pea starch, PeS) crystal types. The morphology of starch samples changed from integral granules to irregular fragments, and the interaction between the exposure OH bonds led to a serious agglomeration. As the treatment times extended, the crystalline structure of starch samples was gradually destroyed, and the excessive treatment approached amorphization. Moreover, the thermal stability of starch samples showed the downward tendency; and with amorphization increased, the swelling power (SP), solubility (S), water absorption capacity (WAC), oil absorption capacity (OAC) and hydrolysis rate of starch samples gradually increased. The obtained results provided a theoretical foundation for broadening the application range of ball-milled starches with different crystal types.

Unlabelled: This study was performed to evaluate the effects of added ingredients such as modified starch (MS), xanthan gum (XG), sugar, (SU), salt (SA), and vinegar (VIN) on the water mobility and physicochemical properties of model tomato ketchup and to investigate the correlation between the obtained variables and serum separation. The type and concentration of ingredients added to the tomato paste (TP) had significant effects on experimental variables, including the serum separation rate, water mobility, and viscosity. Serum separation was most severe in SU and VIN- added samples and minimal in MS and XG- added samples.

To determine the fermentation capacity of gut microbiomes with diverse plant carbohydrate active enzyme (CAZyme) repertoires, we collected fecal samples from 18 healthy adults who reported consuming at least 5 different fruits and vegetables daily and conducted shotgun metagenome analysis. Five fecal samples with the most diverse CAZymes were then fermented with 7 different fibers selected for their unique monosaccharide profiles-banana, kale,13-bean soup, flax, coconut flour, MS Prebiotic (resistant starch) and Sunfiber (guar gum)-for 72 hours. Samples were collected at 4 timepoints for 16S sequencing, and pH, SCFAs, and monosaccharide measurements.

Molecular recognition and determination of vascular cell adhesion molecule-1 (VCAM-1), interleukin-6 (IL-6), and natriuretic peptide C-type (NPPC) are essential for the early prognosis and diagnosis of cardiovascular diseases, especially in young obese populations. Highly sensitive and selective devices characterized by low Limits of quantification are required for their determination in whole blood. Therefore, a 3D stochastic sensor was developed by immobilizing a chitosan hydrogel onto a carbon paste electrode (used as the support matrix for the hydrogel), which was subsequently modified with gold nanoparticles, multi-walled carbon nanotubes, and β-cyclodextrin (β-CD/AuNPs@MWCNT/CS/CPE).

Ultrasonication (US) pretreatment (10 and 20 min) before octenyl succinic anhydride (OSA, 3 %) esterification significantly increased the degree of substitution (DS) in proso millet starch, increasing it from 0.0078 to 0.0115.

Extreme temperature fluctuations during routine handling and shipping of cryopreserved cell products significantly compromise product quality in ways that extend beyond the duration and peak temperature of the fluctuation. The type of cryoprotectant used and the initial ice nucleation temperature influence ice crystal growth during rewarming events, in turn impacting cell survival. Using a cryomicroscope together with temperature profiles recorded in cord-blood units, ice crystal growth was tracked through five transient-warming events (TWEs) that peaked at -30 °C, -20 °C, or -10 °C.
