SummaryTo explore the feasibility of using radio frequency (RF) heating as a method to process kiwi puree, this study compared the effects of RF heating with traditional heat pasteurisation (TP) on various properties of kiwi puree. RF treatment completely inactivate of microbes in kiwi puree, with total aerobic bacteria counts (TAC) decreased by 4.81 log CFU mL À1 and yeast and mould counts (YMC) decreased by 2.62 log CFU mL
À1, which are similar to TP treatment. During the 7 weeks' storage, RF-treated puree showed retarded growth of microbes. The pH, titratable acidity and°Brix values of RF-treated samples were significantly different from those of the control. The vitamin C, total phenolic compounds and antioxidant capacity of RF-treated samples were significantly higher than those of TP-treated samples during storage. RF-treated sample retained better colour than TP-treated sample throughout storage. The customer satisfaction analysis indicated that consumers prefer RF-treated kiwi puree than TP-treated samples. These findings suggest that RF heating has potential applications in processing of kiwi puree or similar products.
Medicinal plant extracts are commonly applied for infectious diseases and are perceived as alternatives to conventional antimicrobial agents. We aimed to confirm the efficacy of phytotherapy for denture stomatitis compared with conventional therapies and placebo. A comprehensive literature search was conducted in Pubmed, Embase, Cochrane Library (CENTRAL), Scopus, and Web of Science, in addition to manual searching. Randomized controlled trials (RCTs) published in English, and studying the treatment of denture stomatitis with herbal medicines, were included. The outcome measures included the relief of clinical signs, reduced Candida colony counts, adverse effects, and patient satisfaction. Nineteen RCTs were included for a systematic review based on selection criteria. Two of them were analyzed using a random‐effects model. There was no difference in the relief of clinical signs (odds ratio (OR) = 0.96; 95% confidence interval (CI): 0.43–2.15) and microbiological improvement (OR = 1.74; 95% CI: 0.55–5.45) between propolis and miconazole. Most of the included studies showed that phytomedicines had fewer side effects and more patient satisfaction than antifungals or disinfectants. However, further RCTs with more standardly prepared herbal formulations are required to verify the clinical efficacy of phytotherapy as an alternative or adjunctive therapy for denture stomatitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
