We investigated various processing conditions to optimize the yield and biofunctional properties of these unpurified, hydrothermally produced XOS-rich hemicellulose hydrolysates from sugarcane bagasse. The prebiotic efficacy of these unpurified XOS-rich hydrolysates was evaluated by their ability to support the metabolism of bifidobacteria in anaerobic fermentation. The results revealed that the chain length of XOS significantly influenced their effectiveness as a carbon source, with longer chains (beyond hexoses) being less efficient. Despite the presence of lignin and sugar degradation by-products, generally considered detrimental in such processes, they did not negatively affect bifidobacteria growth. In addition, variations in the degree of acetyl substitutions on the XOS mildly influenced the production of short-chain fatty acids. Importantly, unpurified XOS-rich hydrolysates produced under selected hydrothermal conditions demonstrated bioactive performance that was comparable to, or even superior to, commercial prebiotics. These findings confirm the practical viability of using unpurified, hydrothermally derived XOS-rich hydrolysates from sugarcane bagasse as prebiotics, emphasizing the innovative approach of eliminating purification and additional processing, thereby simplifying the production process while still maintaining high prebiotic efficacy.</p>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, we aimed to study the effects of pig and cow BS applications on yield formation, morpho-anatomical, mechanical, physiological properties and transcript expression patterns. The results showed that the yield and lodging resistance of rapeseed were synergistically improved via applying full BS dosage versus nitrogen fertilizer (CK). In addition, the seed yield was significantly increased by 23.9 % by promoting the dry matter accumulation and transport-ability, increasing number of pods by 8.4 % and 1000-seed weight by 5.1 %, respectively. Moreover, BS developed the stem mechanical strength by decreasing lodging index by 34.2 %, which was manifested by an increase in stem thickness and stiffness and a reduction in plant height. Besides, it enhanced the photosynthesis through promoting chlorophyll synthesis, delaying plant senescence, and accumulating N and K concentration. Anatomical observations revealed that BS increased greater number and area of stem vascular bundles, vessels, and maintained a dense microstructure than CK. Also, it boosted pectin, Ca<sup>2+</sup> and K<sup>+</sup> contents, which were significantly positively correlated with stem mechanical strength and reduced cellulose, lignin and hemicellulose contents.

First, spectral images of <em>Camellia oleifera</em> seeds from the 400–1000 nm rang were captured, and spectral data from the regions of interest were extracted based on a threshold segmentation method. Then, the partial least squares regression (PLSR) model was used to examine the influence of various preprocessing techniques. It was found that the model performance improved by 7.4 % after standard normal variate (SNV) preprocessing. Meanwhile, an attention mechanism (AM) was introduced into the convolutional neural network regression (CNNR) model, known as ACNNR. The prediction performance of the established models based on full spectra using the traditional (PLSR) and DL methods (CNNR and ACNNR) were compared. Specifically, only raw spectra were taken as inputs for the DL models. The study demonstrated that the model constructed using ACNNR achieved satisfactory results, with R<sup>2</sup><sub>P</sub>, RMSEP, and RPD values of 0. 816, 2.552, and 2.348 in the prediction set, respectively. Moreover, to reduce data dimensionality, the full spectra were downscaled using the successive projections algorithm (SPA), genetic algorithms (GA), CNN, and ACNN.
