The starch property results showed that a higher SPC is associated with lower turbidity, storage and loss modulus after storage, and water solubility, but higher swelling power (SP) and pasting viscosities. These findings suggested that SPC inhibited molecular rearrangement during storage and starch leaching during heating, and enhanced swelling and viscosities due to increased hydration and water uptake caused by the repulsion effect of phosphate groups and a less ordered crystalline structure. Increased SPC also resulted in lower resistant starch (RS) content in a native granular state but higher RS after retrogradation. Pearson correlations further indicated that SPC/C3P/C6P were positively correlated with peak (<em>r</em>² = 0.925, 0.873 and 0.930, respectively), trough (<em>r</em>² = 0.994, 0.968 and 0.988, respectively), and final viscosities (<em>r</em>² = 0.981, 0.968 and 0.971, respectively). Notably, SPC, mainly C3P, exhibited a significantly positive correlation with SP (<em>r</em>² = 0.859) and setback viscosity (<em>r</em>² = 0.867), whereas SPC, mainly C6P, showed a weak positive correlation with RS after retrogradation (<em>r</em>² = 0.746). However, SPC had no significant correlations with water solubility, turbidity and rheology properties, which were more correlated with AC. These findings are helpful for the food industry to select potato starches with desired properties based on their contents of SPC, C3P, or C6P.</p></div>","PeriodicalId":33614,"journal":{"name":"Grain Oil Science and Technology","volume":"7 2","pages":"Pages 79-86"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590259824000189/pdfft?md5=f2d1ef6cf2f096ab650a9b61ecc05313&pid=1-s2.0-S2590259824000189-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140465184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the unreasonable utilization of corn cob often causes the environmental pollution, waste of resources and other problems. As one of the most abundant polymers in nature, xylan is widely used in food, medicine, materials and other fields. Corn cob is rich in xylan, which is an ideal raw material for extracting xylan. However, the intractable lignin is covalently linked to xylan, which increases the difficulty of xylan extraction. It has been reported that the deep eutectic solvent (DES) could preferentially dissolve lignin in biomass, thereby dissolving the xylan. Then, the xylan in the extract was separated by ethanol precipitation method. The xylan precipitate was obtained after centrifugation, while the supernatant was retained. The components of the supernatant after ethanol precipitation were separated by the rotary evaporator. The ethanol, water and DES were collected for the subsequent extraction of corn cob xylan. In this study, a novel way was provided for the green production of corn cob xylan. The DES was used to extract xylan from corn cob which was used as the raw material. The effects of solid-liquid ratio, reaction time, reaction temperature and water content of DES on the extraction rate of corn cob xylan were investigated by the single factor test. Furthermore, the orthogonal test was designed to optimize the xylan extraction process. The structure of corn cob xylan was analyzed and verified. The results showed that the optimum extraction conditions of corn cob xylan were as follows: the ratio of corn cob to DES was 1 : 15 (g : mL), the extraction time was 3 h, the extraction temperature was 60 °C, and the water content of DES was 70%. Under these conditions, the extraction rate of xylan was 16.46%. The extracted corn cob xylan was distinctive triple helix of polysaccharide, which was similar to the structure of commercially available xylan. Xylan was effectively and workably extracted from corn cob by the DES method. This study provided a new approach for high value conversion of corn cob and the clean production of xylan.</p></div>","PeriodicalId":33614,"journal":{"name":"Grain Oil Science and Technology","volume":"7 1","pages":"Pages 50-59"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590259824000037/pdfft?md5=dbe8cacfea64a65bcfd591ab1900fd9f&pid=1-s2.0-S2590259824000037-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139639873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, mass transfer process of peanut protein extracted by bis(2-ethylhexyl) sodium sulfosuccinate (AOT)/isooctane reverse micelles was investigated. The effects of stirring speed (0, 70, 140, and 210 r/min), temperature of extraction (30, 35, 40, 45, and 50 °C), peanut flour particle size (0.355, 0.450, 0.600, and 0.900 mm) and solid-liquid ratio (0.010, 0.0125, 0.015, 0.0175, and 0.020 g/mL) on extraction rate were examined. The results showed that extraction rate increased with temperature rising, particle size reduction as well as solid-liquid ratio increase respectively, while little effect of stirring speed (<em>P</em> &gt; 0.05) was observed. The apparent activation energy of extraction process was calculated as 10.02 kJ/mol and Arrhenius constant (<em>A</em>) was 1.91 by Arrhenius equation. There was a linear relationship between reaction rate constant and the square of the inverse of initial particle radius (1/<em>r</em>₀²) (<em>P</em> &lt; 0.05).

In brief, the extraction process was controlled by the diffusion of protein from the virgin zone interface of particle through the reacted zone and it was in line with the first order reaction.
