Native maize starch (MS) slurry was treated under a specific electric field intensity while maintaining the sample temperature at 25 ± 2 °C for different times (1, 2, 4 and 8 h), which would effectively eliminate the influence of thermal effect on starch. A corresponding low electric field intensity of 3.3–3.4 kV/m was established after adjusting the electrode gap to be 220 mm of the 27.12 MHz RF system. Samples treated without RF-wave for the same time (1, 2, 4 and 8 h) were used as controls. The differences between the effect of these two treatments on the multi-scale structural and gelling properties of starch samples were investigated. Results showed that the low intensity RF-wave treatment enhanced the short-range structural order. A higher degree of order value and the double helical structure were observed from Fourier transform infrared (FTIR) spectra and solid state <sup>13</sup>C nuclear magnetic resonance (<sup>13</sup>C NMR). Moreover, compared to control MS, the crystallinity of low intensity RF-treated starch significantly increased though the crystal pattern remained unchanged. Low intensity RF-wave treated starch had no significant difference in loss modulus, energy and distance of inter-double helices hydrogen bond, and pasting properties (i.e. TV, SB and BD) when compared with control sample. The effect of low intensity RF wave on starch without heating was insufficient to cause macroscopic property changes.

However, this approach does not maximize the utilization of energy. Therefore, this study aims to compare the effect of non-temperature-controlled ultrasound (NTU) and temperature-controlled ultrasound (TU), with IBU on the structure and properties of zein. To further explore the role and mechanism of thermal effects in ultrasound processes. Firstly, particle size, zeta potential, hydrophobicity, and thermal stability of zein nanoparticles prepared using various ultrasound-assisted methods were characterized. Compared to the particle size in the IBU group, the NTU group consistently had smaller particles under the same power conditions (e.g., 197 nm versus 176 nm at U1). The particle size in the TU group changes depending on the temperature (e.g., from native 225 nm down to 185 nm). As for the denaturation temperatures, the NTU group (88.9 °C) was significantly higher than that of the IBU (75.76 °C) and TU groups (e.g., 76.9 °C at treatment temperatures of 30 °C). In all, IBU reduces the thermal stability, while NTU treatment enhances it. Furthermore, UV, fluorescence, and CD spectra results indicate that both NTU and TU groups significantly reduce the α-helix structure by unfolding and exposing more internal hydrophobic groups of zein than the IBU group. These results indicate that the effects of ultrasound on zein are closely related to the heating source during the ultrasonic process. IBU could be utilized to maximize the reduction of denaturation levels, but NTU may exhibit superior performance such as protein modification, reducing particle size, or enhancing stability in industrial production.</div></div>","PeriodicalId":329,"journal":{"name":"Innovative Food Science & Emerging Technologies","volume":"97 ","pages":"Article 103825"},"PeriodicalIF":6.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142318624","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}
