Prior to extraction, one batch of by-product was dehydrated by freeze-drying (untreated by-product), while the other batch was treated by microwave irradiation in conjunction with freeze-drying (microwave-treated by-product). High-performance liquid chromatography (HPLC) was employed for the identification of individual phenolic compounds with potent antifungal activities. Both lemon by-product aqueous extracts inhibited the mycelial growth and suppressed the spore germination of the fungus in a concentration-dependent manner. In general, the extracts obtained from the microwave-treated lemon by-product displayed enhanced antifungal activity than those obtained from the untreated one. Scanning electron microscopy (SEM) revealed that both lemon by-product extracts affected the hyphal morphology of the fungus. The antifungal activity of the extracts was attributed to their phenolic acid and ascorbic acid contents.]]> Wed 31 Oct 2018 15:06:13 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33080 −1, respectively. The carotenoid extraction yield and the antioxidant capacity extraction yield were 271 mg/100 g DW and 737 μm TE/100 g DW, respectively. Thus, the extraction using ethyl acetate with the ratio of 80:1 (mL solvent per g Gac peel) for 150 min at 40.7°C is suggested for recovering carotenoids and antioxidant capacity from Gac peel.]]> Wed 04 Sep 2019 09:54:30 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32046 p‐coumaric acid content. The highest gallic acid content was recorded in the pomace dried by hot air at 110°C. The results of this study indicate that drying technique should be carefully selected according to the bioactive compounds aimed to be extracted.]]> Tue 24 Apr 2018 15:09:46 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20088 Sat 24 Mar 2018 08:00:09 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27134 Momordica cochinchinensis Spreng.) is a tropical vine originating from South and South-East Asia. Gac fruit has traditionally been used in Asia to provide red colour for cuisines and enhance visional health. Recently, Gac fruit has emerged as a potential source of carotenoids, especially lycopene and β-carotene. Carotenoids and other identified bioactives from this fruit including phenolics, flavonoids and trypsin inhibitors are associated with many beneficial bioactivities such as antioxidant, anticancer and provitamin A activities. In addition to the traditional utilisation, commercial products like Gac powder and Gac oil have been manufactured as natural colourants and medicinal supplements. This paper is a review of the scientific literature on the nutritional composition, biological activities and processing of Gac fruit.]]> Sat 24 Mar 2018 07:33:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25688 Sat 24 Mar 2018 07:28:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52834 Mon 30 Oct 2023 09:39:46 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33067 Sargassum vestitum, Sargassum linearifolium, Phyllospora comosa, Padina sp., Hormosira banksii and Sargassum podocanthum, were investigated for the chemical profile and antioxidant activity. The results showed that the extracts H. banksii, S. vestitum and Padina sp. indicated the significantly higher total phenolic compound (TPC) and antioxidant activities (ABTS, DPPH and FRAP) compared to the other species (P < 0.05) and comparable to positive controls: butylated hydroxytoluene, ascorbic acid and alpha‐tocopherol at the concentrations (0.06–1 mg mL−1). Fucoxanthin was also found in six species and isolated for evaluating antioxidant activity. In addition, the phenolic compounds were mainly responsible for antioxidant activity of the extracts, while fucoxanthin showed quite high antioxidant activity. It is suggested that S. vestitum, H. banksii and Padina sp. have the potent for extracting bioactive components and further applications in food and pharmaceutical industries.]]> Fri 24 Aug 2018 13:45:12 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34626 Fri 05 Apr 2019 11:33:24 AEDT ]]>
