However, as the high oil and acrylamide contents in fried foods may contribute to increased risks of obesity, diabetes, hypertension and cancer, methods to reduce these harmful components have become a research focus. In this study, the impacts of pulsed electric fields (PEF) and ultrasound (US) on the frying kinetics and characteristics of sweet potato chips were investigated. The intensity of PEF treatment was set at <em>E</em> = 1.0 kV/cm with a total duration of t<sub>PEF</sub> = 0.2 s; the energy applied in the PEF pre-treatment was 9.47 ± 0.5 kJ/kg. US treatment was performed at 53 kHz (10 s ON/1 s OFF), 180 W, and 25 °C for 30 min. Low-field nuclear magnetic resonance (LF–NMR) revealed that both PEF and US pre-treatment influence the binding force between water molecules in sweet potatoes. Reducing sugars in raw products treated with PEF, US, and PEF + US were significantly (p &lt; 0.05) reduced by 33.3 %, 20.0 %, and 53.3 %, respectively. The first-order kinetics model provided a good fit for water evaporation during frying. The PEF, US, and PEF + US treatments resulted in oil content reductions of 32.3 %, 37.0 %, and 40.3 %, respectively, compared with the untreated samples. Pre-treatments also improved the color and textural characteristics of fried sweet potato chips. Furthermore, the acrylamide content was reduced by 55.28 % (549 µg/kg) with PEF + US pre-treatment.

Conventionally, 1,3-propanediol (1,3-PDO) has been derived from petroleum-based feedstocks through chemical processes, which pose significant cost and environmental concerns. This has prompted the exploration of sustainable biological production methods using microorganisms to ferment glycerol, the main by-product of palm oil transesterification in biodiesel production. However, downstream purification remains complex and inefficient. To address this, our study introduces a novel and economically viable purification strategy for 1,3-PDO derived from a semi-industrial fermentation broth. The purification process involves pre-treatment steps: centrifugation, flocculation with chitosan, decolorization with activated charcoal, and broth concentration via rotary evaporation. These steps resulted in a transparent broth with a minimal 6 % loss of 1,3-PDO. Various resin types, including Sulfonated Styrene Divinylbenzene (S-SDVB) and Styrene Divinylbenzene (SDVB) ion exchange resins in different ionic forms in addition to silica gel resin, were evaluated for their effectiveness in separating 1,3-PDO in terms of recovery and purity. A key aspect of our study is the detailed investigation of the equilibrium adsorption characteristics of SDVB and S-SDVB resins, each with different ion forms. This analysis provides insights into how resin modifications affect the separation process, aiming for higher yields and purities of 1,3-PDO. The findings revealed that the Langmuir adsorption isotherm fits experimental data. Column chromatography experiments showed SDVB resins' deficiencies in separating 1,3-PDO from other components, while silica gel resin achieved a recovery rate exceeding 96 % purity and approximately 80 % overall recovery. Notably, the Ca<sup>2+</sup> form of S-SDVB resin achieved high recovery (95–100 %) and purity (91–93 %) in both synthetic and real fermentation broths, addressing biodiesel challenges and proposing a solution for large-scale microbial 1,3-PDO production.</div></div>","PeriodicalId":12134,"journal":{"name":"Food and Bioproducts Processing","volume":"149 ","pages":"Pages 100-111"},"PeriodicalIF":3.5,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142702172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
