For example, during the Covid pandemic, submissions increased significantly as researchers cleared out their unpublished data. That was followed by a small dip in submissions last year, again related to the pandemic—perhaps due to a time lag between renewal of experimentation and publication.</p><p>We are now out of that dip and have seen a startling increase in submissions over the past year, to the point where all of our editors are maxed out. Many of our Associate Editors (AEs) have over 10 manuscripts in their system at the moment, beyond anyone's expectations.</p><p>For historical perspective, the table shows the submission trends since 2015. There was a general, slow increase and then a plateau between 2015 and 2019. During Covid, starting in 2020, everyone was writing up old research and new reviews as a means of keeping busy, so submissions trended upward. But then in 2022, we had a “Covid dip,” perhaps because researchers were once more getting back into the lab to generate data and not necessarily writing as much. The number of submissions rose last year, to 1941, about where we were in 2016. There was an average of five manuscripts submitted per day last year. As of September 5, this year, we already have 1952 submissions, with an average daily rate of 7.8. At this pace, we expect to see a record number of submissions, even above the Covid years. If submissions continue at this rate, we project over 2800 manuscript submissions this year.\u0000\u0000 </p><p>We are scratching our head trying to understand what is driving this increase. It is not just us, though; many journals are seeing this increase. We hear that other publishers and journals are seeing an increase in submissions of 18%–20%. Our increase will likely be greater than that, maybe as much 35% over the 2023 submissions (and still 6% greater than our boom year in 2021).</p><p>One of our contacts postulated that this spike could be the result of authors choosing to publish in journals long known to uphold high standards of research integrity, such as society journals. They stated that authors appear to be moving away from Frontiers, MDPI, the former Hindawi journals, and other born-OA publishers who were hit hard by paper mills, AI-generated, and poorly reviewed papers.</p><p>What this boom has meant to us is that the entire editorial staff is overwhelmed. The Scientific Editors (SEs) have many more papers to assign, to the same AEs, who are all overloaded. Finding reviewers for all these submissions requires an ever-expanding pool of willing reviewers. In response to this surge in submissions, we have recently added one new SE and five new AEs. We will be evaluating candidates for Editorial Board (EB) members-at-large as we close out the year, with hopes of adding up to 10 new people, selected based on all the factors discussed in my March and April editorials.

Then the effect of TG on the mechanical, physical, barrier, and microstructural properties of the WPC/EWP composite biodegradable film was investigated, and its preliminary application potential was explored. Compared to WPC and EWP films, WPC/EWP composite film had higher transmittance, tensile strength (TS), and thermal stability. Fluorescence results showed that the film experienced fluorescence quenching after TG treatment. Fourier transform infrared and x-ray diffraction results showed that WPC and EWP had good compatibility in the biodegradable film, the hydrogen bond interaction of film was increased due to TG, resulting in an increase in TS. Meanwhile, the water vapor permeability and contact angle of WPC/EWP film treated with TG at 5 U/g protein increased by 28% and 76.1%, respectively. Besides, the WPC/EWP biodegradable film modified by TG (TG-W/E) was applied as a coating film on cherry tomatoes, effectively reducing the weight loss rate during storage from 14.2% to 10.8%. Furthermore, indexes, such as solid content, spoilage rate, hardness, pH, and lycopene, showed that the film had a good preservation effect on cherry tomatoes. To conclude, the appropriate addition of TG has a positive effect on the film properties of the WPC/EWP biodegradable film, which is beneficial to the development and utilization of protein-based film. WPC/EWP biodegradable film modified by TG has a great application prospect in extending the shelf life of fruit and vegetable.</p>","PeriodicalId":193,"journal":{"name":"Journal of Food Science","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142613194","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}

Its pathogenesis is possibly linked to gut microbiota dysbiosis. This study investigates the preventive effects of chitosan self-assembled coconut residue dietary fiber (CRFSC) on hyperlipidemia induced by a high-fat diet (HFD) and gut microbiota. CRFSC resulted in a significant weight loss of 7.9% in HFD rats and had a preventive effect on all four lipid parameter abnormalities. HFD supplemented with oat group resulted in a weight loss of 3.8% in HFD rats and had no preventive effect on low-density lipoprotein cholesterol (LDL-C) abnormalities. Prevention was achieved not only through the modulation of gut microbiota composition and the increase of short-chain fatty acids (SCFAs) levels, but also through the activation of superoxide dismutase enzyme and the inhibition of malondialdehyde accumulation, all of which are the factors leading to the controlling of lipid abnormalities and oxidative damage. The prevention of lipid parameters by chitosan self-assembled coconut residue dietary fiber (CRFSC) may be attributed to its richness in chitosan and insoluble dietary fiber, as well as its ability to enrich beneficial bacteria such as Akkermansia, Roseburia, and Ruminococcus. Correlation analysis demonstrated that key bacterial species producing SCFAs, which are rich in the CRFSC diet, had a positive impact on controlling hyperlipidemia. Hence, consumption of a CRFSC diet could serve as an effective strategy for preventing and controlling the development of hyperlipidemia due to its potential ability to regulate gut microbiota and SCFAs. PRACTICAL APPLICATION: This study showed that dietary fiber from coconut residue after chitosan self-assembly had preventive effects on overweight, dyslipidemia, and oxidative damage in rats. In addition, CRFSC also increased the content of short-chain fatty acids in the gut. And improve gut health by affecting gut microbiota. This finding suggests that CRFSC can be used as a dietary strategy to prevent hyperlipidemia and has practical significance in developing new healthy foods.</p>","PeriodicalId":193,"journal":{"name":"Journal of Food Science","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142581531","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}

The results showed that vacuum-ultrasonic-assisted treatment greatly accelerated the transfer of moisture and NaCl, and the highest yield was obtained by ultrasonic power of 450 W. The mass transfer kinetics (k<sub>1</sub> and k<sub>2</sub>) were significantly related to vacuum pretreatment and ultrasonic power.

The results suggested that the acoustic power density substantially modified the chemical interaction forces between RRPI molecules.
