[Ab] Resumo:This study aimed to investigate the fermentation quality and nutritive value of total mixed ration (TMR) silages based on desert wormwood (DW) combined with early stage corn (ESC) as forage and determine an optimum formula. Desert wormwood and ESC were harvested, chopped, and mixed with other ingredients according to a formula, packed into laboratory silos at densities of 500-550 g/L, and stored in the dark for 60 days. The DW proportions in the forage of TMR were 1, 0.75, 0.50, 0.25 and 0, based on fresh weight. As the proportion of DW decreased, the pH also decreased (P < 0.05), while lactic acid, lactic acid/acetic acid, crude protein, starch, and the in vitro digestibility of dry matter and neutral detergent fiber increased (P < 0.05). Ammonia nitrogen/total nitrogen in the TMR silages with DW proportions of 0.75, 0.25 and 0 in the forage was more than 10%. These results indicated that the quality of the TMR silage containing DW alone as forage was poor, TMR silages containing DW proportions of 0.75 and 0.25, and ESC alone, in the forage were not well preserved. The optimum TMR silage formula contained a DW proportion of 0.5 in the forage.

[Ti] Título:Insights into the multi-scale structure and digestibility of heat-moisture treated rice starch.

[Ab] Resumo:The digestibility and structural changes of rice starch induced by heat-moisture treatment (HMT) were investigated, and the relationships among the moisture content-starch structure-starch digestibility were revealed. HMT could simultaneously disorder and reassemble the rice starch molecules across multi-scale lengths and convert some fractions of rapidly-digestible starch (RDS) into slowly-digestible starch (SDS) and resistant starch (RS). In particular, the HMT rice starch with less than 30% moisture content showed a higher SDS+RS content (25.0%). During HMT, SDS and RS were preferably formed by the degraded starch molecules with M between 4×10 and 4×10 g/mol, single helices and amylose-lipids complexes that were formed by degraded starch chains with higher thermal stability and crystalline lamellae with greater thicknesses. Thus, our research suggests a potential approach using HMT to control the digestion of starch products with desired digestibility.

[Ti] Título:Effects of low molecular sugars on the retrogradation of tapioca starch gels during storage.

[Ab] Resumo:The effects of low molecular sugars (sucrose, glucose and trehalose) on the retrogradation of tapioca starch (TS) gels stored at 4°C for different periods were examined with different methods. Decrease in melting enthalpy (ΔHmelt) were obtained through differential scanning calorimetry analysis. Analysis of decrease in crystallization rate constant (k) and increase in semi-crystallization time (τ1/2) results obtained from retrogradation kinetics indicated that low molecular sugars could retard the retrogradation of TS gels and further revealed trehalose as the best inhibitor among the sugars used in this study. Fourier transform infrared (FTIR) analysis indicated that the intensity ratio of 1047 to 1022 cm-1 was increased with the addition of sugars in the order of trehalose > sucrose > glucose. Decrease in hardness parameters and increase in springiness parameters obtained from texture profile analysis (TPA) analysis also indicated that low molecular sugars could retard the retrogradation of TS gels. The results of FTIR and TPA showed a consistent sugar effect on starch retrogradation with those of DSC and retrogradation kinetics analysis.

[Ti] Título:Tunable d-Limonene Permeability in Starch-Based Nanocomposite Films Reinforced by Cellulose Nanocrystals.

[Ab] Resumo:In order to control d-limonene permeability, cellulose nanocrystals (CNC) were used to regulate starch-based film multiscale structures. The effect of sphere-like cellulose nanocrystal (CS) and rod-like cellulose nanocrystal (CR) on starch molecular interaction, short-range molecular conformation, crystalline structure, and micro-ordered aggregated region structure were systematically discussed. CNC aspect ratio and content were proved to be independent variables to control d-limonene permeability via film-structure regulation. New hydrogen bonding formation and increased hydroxypropyl starch (HPS) relative crystallinity could be the reason for the lower d-limonene permeability compared with tortuous path model approximation. More hydrogen bonding formation, higher HPS relative crystallinity and larger size of micro-ordered aggregated region in CS0.5 and CR2 could explain the lower d-limonene permeability than CS2 and CR0.5, respectively. This study provided new insight for the control of the flavor release from starch-based films, which favored its application in biodegradable food packaging and flavor encapsulation.

[Ab] Resumo:The C halophytic species Suaeda monoica and S. fruticosa, possess the C photosynthesis pathway without Kranz anatomy were grown at ambient (470ppm CO ) and elevated (850ppm CO ) atmospheric CO under control containment facility to study the plant response under CO stress condition. The relative growth of both Suaeda species was enhanced with atmospheric CO enrichment compared to control (ambient) condition. The photosynthesis rate was found 2.5µmolCO m s in both species under stress condition compared to about 1.9µmolCO m s under control conditions. About 0.3molH Om s conductance was detected under an unstressed condition which decreased significantly to ~0.07molH Om s on the 6th day of stress treatment. Similarly, transpiration rate was also decreased significantly from 4.4-5.2mmolH Om s to 1.7-1.9 under stress condition. In contrast, VpdL increased significantly from 1.9kPa to 2.5kPa under stress condition. A higher total chlorophyll content observed in S. monoica (56.36mgg tissue) compared to S. fruticosa (33.12mgg tissue) under unstressed (control) condition. A significant increase was found in the total chlorophyll content of S. fruticosa (45.47mgg tissue) with stress treatment compared to control (33.12mgg tissue). In contrast, the total chlorophyll decreased in S. monoica (51.58mgg tissue) under similar stress condition compared to control plants (56.36mgg tissue). About 6-6.8mg total sugar per gram tissue found under control condition which enhanced further (7.5 to 11mgg tissue) under stress condition. Similarly, total reducing sugar (~2mgg tissue) and total starch content (6.5-11mgg tissue) increased under stress condition. About 6.5- and 3- fold higher expression of PPDK gene was observed for S. monoica and S. fruticosa, respectively under CO stress condition. PPDK (1.2- and 1.5- fold) and antioxidant enzymes; APX (12.7- and two-fold), CAT (2.2- and 6.4- fold) and SOD (4.6- and 94- fold) enhanced significantly in S. fruticosa and S. monoica, respectively under high CO stress condition compared to control plants. Overall, it was observed that PPDK enzyme plays a key role in C photosynthesis pathway and S. monoica is a potential candidate to be explored further for the saline agricultural and CO capture.

[Ab] Resumo:A bioflocculant (MBFA18) was produced by Aspergillus niger (A18) using potato starch wastewater (PSW) as nutrients. The cultivation processes and flocculating treatment for PSW purification were systematically studied. The flocculating rate of the MBFA 18 achieved 90.06% (kaolin clay) under the optimal cultivation condition (PSW with 5950 mg/L COD, 20 g/L glucose, 0.2 g/L urea and without phosphorus source addition and pH adjustment). Furthermore, effects of flocculant dosage, initial pH, coagulant aid (CaCl2) addition and sedimentation time on the PSW treatment were discussed and studied in detail. The optimum flocculation treatment conditions were determined according to the treatment efficiency, cost and flocculation conditions. During the PSW treatment, 2 mL/L bioflocculant (1.89 g/L) dosage and 0.5 mol/L coagulant aid addition were applied without pH adjustment and 91.15% COD and 60.22% turbidity removal rate could be achieved within 20 min. The comparative study between the bioflocculant and conventional chemical flocculants showed excellent flocculating efficiency of MBFA 18 with lower cost (4.7 yuan/t), which indicated that the bioflocculant MBFA 18 produced in PSW substrate has a great potential to be an alternative flocculant in PSW treatment.

[Ab] Resumo:The objective of this study was to provide understanding about the efficacy of decreasing dough hydration to slow down starch digestibility in white bread. Breads were made with 45 (low hydration bread, LHB), 60 (intermediate hydration bread, IHB) and 75% (high hydration bread, HHB) water (flour basis). A hydration depletion down to 45%, which is close to the minimum hydration found in commercially available white bread, did not prevent the starch in the crumb from complete gelatinization. However, LHB and IHB crumbs were more resistant to physical breakdown during in vitro digestion than HHB crumbs, resulting in a 96.81% increase of slowly digestible starch (SDS) from 75 to 45% dough hydration. The degree of gelatinization in crust samples was significantly reduced with a depletion in the dough hydration, ranging from 29.90 to 44.36%, which led to an increase of SDS from 7.41 in HHB to 13.78% in LHB (bread basis).

[Ti] Título:Mechanisms Underlying the Formation of Complexes between Maize Starch and Lipids.

[Ab] Resumo:This study aimed to reveal the mechanism of formation of complexes between native maize starch (NMS) and different types of lipids, namely palmitic acid (PA), monopalmitate glycerol (MPG), dipalmitate glycerol (DPG), and tripalmitate glycerol (TPG). The complexing index followed the order of MPG (96.3%) > PA (41.8%) > TPG (8.3%) > DPG (1.1%), indicating that MPG formed more complexes with NMS than PA, and that few complexes were formed between NMS and DPG and TPG. The NMS-PA complex presented higher thermal transition temperatures and lower enthalpy change than the NMS-MPG complex, indicating that although MPG formed more starch complexes, they had less stable crystalline structures than the complex between NMS and PA. X-ray diffraction (XRD) and Raman spectroscopy showed that both MPG and PA formed V-type crystalline structures with NMS, and confirmed that no complexes were formed between NMS and DPG and TPG. We conclude that the monoglyceride formed more starch-lipid complex with maize starch than PA, but that the monoglyceride complex had a less stable structure than that formed with PA. The di- and triglycerides did not form complexes with maize starch.

[Ab] Resumo:Fluorescent organic nanoparticles (FONs) have been regarded as the promising candidates for biomedical applications owing to their well adjustment of chemical structure and optical properties and good biological properties. However, the preparation of FONs from the natural derived polymers has been rarely reported thus far. In current work, we reported a novel strategy for preparation of FONs based on the self-polymerization of starch-dopamine conjugates and polyethyleneimine in rather mild experimental conditions, including air atmosphere, aqueous solution, absent catalysts and at room temperature. The morphology, chemical structure and optical properties of the resultant starch-based FONs were investigated by different characterization techniques. Biological evaluation results demonstrated that these starch-based FONs possess good biocompatibility and fluorescent imaging performance. More importantly, the novel strategy might also be extended for the preparation of many other carbohydrate polymers based FONs with different structure and functions. Therefore, this work opens a new avenue for the preparation and biomedical applications of luminescent carbohydrate polymers.

[Ab] Resumo:In Neurospora crassa, the transcription factor COL-26 functions as a regulator of glucose signaling and metabolism. Its loss leads to resistance to carbon catabolite repression. Here, we report that COL-26 is necessary for the expression of amylolytic genes in N. crassa and is required for the utilization of maltose and starch. Additionally, the Δcol-26 mutant shows growth defects on preferred carbon sources, such as glucose, an effect that was alleviated if glutamine replaced ammonium as the primary nitrogen source. This rescue did not occur when maltose was used as a sole carbon source. Transcriptome and metabolic analyses of the Δcol-26 mutant relative to its wild type parental strain revealed that amino acid and nitrogen metabolism, the TCA cycle and GABA shunt were adversely affected. Phylogenetic analysis showed a single col-26 homolog in Sordariales, Ophilostomatales, and the Magnaporthales, but an expanded number of col-26 homologs in other filamentous fungal species. Deletion of the closest homolog of col-26 in Trichoderma reesei, bglR, resulted in a mutant with similar preferred carbon source growth deficiency, and which was alleviated if glutamine was the sole nitrogen source, suggesting conservation of COL-26 and BglR function. Our finding provides novel insight into the role of COL-26 for utilization of starch and in integrating carbon and nitrogen metabolism for balanced metabolic activities for optimal carbon and nitrogen distribution.
