Summary: This study investigated the effects of pullulanase debranching on the structural properties and digestibility of maize starch-glyceryl monostearate complexes. The results showed that pullulanase debranching for 16 hours significantly increased the amylose content and complex index of maize starch. The crystallinity and short-range orders structure of the complexes also increased, leading to a higher resistant starch content and anti-digestibility. This work suggests that debranching pretreatment is an efficient way to produce ordered starch-lipid complexes with controllable structure and anti-digestibility.

Summary: In this work, valorization of downgraded potatoes' starch was achieved through the preparation of starch nanoparticles using different physical methods and enzymatic hydrolysis. The physical modification methods led to moderate alterations in the size and crystallinity of the starch granules, while enzymatic hydrolysis using Pullulanase enzyme resulted in the production of very small starch nanoparticles. The effects of enzyme concentration, temperature, and pH on the hydrolysis process were also investigated.

Summary: This study evaluated the properties of amylose-lipid complexes in rice and wheat flours using pullulanase as a debranching enzyme. The treated compounds, RPF and FPF, exhibited higher complex index, lower hydrolysis values, lower swelling power, and higher water solubility values compared to enzyme-untreated complexes. In vivo studies showed that RPF and FPF had a smaller impact on blood glucose levels, suggesting their potential as functional food ingredients.

Summary: This study investigated the fermentation of resistant starch from the starch-ferulic acid inclusion complex. The results showed that the complex-based resistant starch, high-amylose corn starch, and the mixture of ferulic acid and high-amylose corn starch were mainly utilized initially. Additionally, the complex-based resistant starch led to the highest production of short-chain fatty acids (SCFAs), the lowest ratio of Firmicutes/Bacteroidetes (F/B), and the most abundance of beneficial bacteria.

Summary: The study investigated the physicochemical, rheological properties and structure of potato starch and starch-tea polyphenols (TPs) complex modified by enzyme and alcohol. TPs inhibited the aggregation of amylose and retrogradation of starch TPs complex, resulting in decreased gel strength, increased viscosity, and gelatinization stability of starch granules. The formation of complex between TPs and native/modified potato starch could be used in food industrial applications due to the inhibition of starch retrogradation.

Summary: A novel type I pullulanase (PulM) with optimal debranching activity at 40 degrees C and pH 6.0 to 7.0 was identified in this study. PulM showed cold-active properties with over 50% enzymatic activity detected at 4 degrees C. The enzyme efficiently catalyzed the hydrolysis of alpha-1,6-glycosidic linkages in pullulan and increased the apparent amylose content of potato starch by about 80%. The debranched starch led to the formation of resistant starch 3, which exhibited higher crystallinity, enhanced heat-stability, and resistance to alpha-amylase digestion compared to native starch.

Summary: Papain-pretreated sorghum grains were modified using pullulanase and infrared irradiation to reduce starch digestibility. The combination of pullulanase (1 U/ml/5h) and IR (220°C/3 min) treatment showed the best synergistic effect, producing modified corneous endosperm starch with a hydrolysis rate of 0.022, a hydrolysis index of 42.58, and a potential digestibility of 0.468. The modification increased the amylose content and crystallinity of the starch, but decreased its swelling power, solubility index, and pasting properties. The combination of debranching and infrared treatment can be an efficient method to produce tailor-made starch for food industries.

Summary: A high-performance Au@MIL-101/PMMA/DT surface-enhanced Raman scattering (SERS) substrate was fabricated for sensitive and stable detection of paraquat by self-assembling metal organic framework-modified Au nanoparticles (Au@MIL-101) on a poly(methyl methacrylate) (PMMA) film and then immobilizing the formed substrate onto a duct tape (DT). The substrate exhibited outstanding uniformity with relative standard deviations of 9.47% and storage stability for 2 months. For detecting paraquat, the substrate showed a low detection limit of 7.1 x 10(-9) M (1.83 μg/kg) and wide linear range from 10(-8) to 10(-2) M. Furthermore, the substrate showed good detection performance in real cereal samples with desirable recovery rates from 91.57% to 102.32%.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
