But, it usually needs to be dried for longer preservation. Hence, this research is aimed at examining the drying kinetics and quality attributes of dried red peppers utilizing various solar drying methods, in comparison with traditional open sun drying (OSD) and industrial laboratory thin layer dryers (LTLD). Analysis parameters employed include determining moisture content, measuring color properties, evaluating antioxidant capacity, analyzing capsaicinoid content, and assessing microbial presence. The drying process took place in a sunny environment with fluctuations in temperature and relative humidity as evidence of the dynamic conditions experienced within the solar dryers. It was observed that the logarithmic model was the most accurate in predicting moisture ratio over time, estimating a drying time of 25 hours to achieve 10% moisture content. The result demonstrated that direct solar dryers (DSD), indirect solar dryers (ISD), and mix mode solar dryers (MMSD) methods showed moderate changes in color parameters, with average <i>Δ</i><i>L</i>∗, <i>Δ</i><i>a</i>∗, and <i>Δ</i><i>b</i>∗ values of -5.08, -23.71, and -13.62, respectively. The average overall color difference (<i>Δ</i><i>E</i>) for these methods was 27.96. In addition, after comparing it to the LTLD method, which showed the highest content of phenolic compounds at 47.89%, MMSD displayed a slightly lower content of 44.71%. Similarly, MMSD exhibited higher levels of DPPH radical scavenging activity and ferric reducing power, measuring at 44.22% and 1163.75 <i>μ</i>mol Fe<sup>2+</sup>/L, respectively. The capsaicin content remained relatively consistent across all drying methods, with MMSD, DSD, and LTLD demonstrating similar levels of approximately 31 mg/g. Although MMSD had slightly higher mold and yeast counts compared to LTLD, ISD, and DSD, it remained lower than OSD (less than 0.56 <span></span><math></math>). Furthermore, MMSD showed a lower total microbial count in comparison to other drying methods. These findings suggest that MMSD shows promise as a drying technique for preserving the phenolic compounds and antioxidant activity of the dried product.</p>\u0000 </div>","PeriodicalId":15717,"journal":{"name":"Journal of Food Processing and Preservation","volume":"2024 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/7987269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141246116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study is aimed at investigating the effects of the solid-state fermentation of <i>Ganoderma lucidum</i> on soluble sugar metabolism in three summer–autumn black tea varieties. In this study, we combined targeted metabolomics technology, gas chromatography-mass spectrometry, and multivariate statistical analysis to reveal the metabolic rules of 13 different sugars in three varieties of summer–autumn black tea under the action of <i>Ganoderma lucidum</i>.

Although adding dietary fiber-rich materials into pasta formula can increase the dietary fiber content, this approach counters several technological problems as the cooking and textural properties of the resulting pastas are usually negatively affected. This study is aimed at utilizing sweet corn “milk” residue (SCMR), a food by-product, and transglutaminase to develop fiber-rich pasta. Durum wheat semolina was replaced by SCMR powder at the ratio of 0 (control), 5, 10, 15, and 20% to make SCMR-fortified pasta. The chemical compositions and cooking and textural properties of the fortified pasta were then quantified. As the replacement ratio increased, the dietary fiber content, total phenolic content (TPC), and antioxidant properties of pasta were considerably improved while the cooking and textural attributes were negatively impacted. At 20% SCMR fortification, the dietary fiber content and TPC of the pasta were increased by 3.2 and 1.2 times, respectively, while the cooking loss increased by 73% as compared to those of the control pasta. Meanwhile, the chewiness, cohesiveness, tensile strength, and elongation rate at break of the 20% SCMR-fortified pasta were reduced by 19%, 26%, 21%, and 65%, respectively, compared to those of the control pasta. To improve the cooking properties and the textural properties of the fortified pasta, transglutaminase was added to the pasta dough with 20% SCMR. The effect of transglutaminase was enzyme-dose dependent. The cooking and textural qualities of pasta were improved as enzyme concentration increased 0 to 0.75 U/g protein and declined as the enzyme concentration increased from 0.75 to 1.25 g/U protein. At the optimal concentration of transglutaminase (0.75 U/g protein), the cooking loss reduced by 16% while the chewiness, cohesiveness, tensile strength, and elongation rate increased by 18%, 11%, 31%, and 32% compared to those without transglutaminase. <i>Novelty Impact Statement</i>. This study focuses on developing the dietary fiber-enriched pasta using sweet corn “milk” residue and transglutaminase enzyme. The results showed that replacing 20% durum wheat semolina with SCMR powder significantly enhanced the dietary fiber and total phenolic content of the pasta but negatively affect the cooking and textural properties of the pasta. Adding transglutaminase at 0.75 U/g protein to the SCMR-semolina blended dough successfully restored the adverse effects of SCMR on the cooking and textural properties.
