Aqueous Formulations Of 1h-Cyclopropabenzene Modulate Ethylene Production And Fruit Quality In Japanese Plums, Poe N. Kyaw, Zora Singh, Vijay Y. Tokala
Research outputs 2014 to 2021
The efficacy of aqueous formulations of 1H-cyclopropabenzene (BC) containing different adjuvants to retard ethylene production and maintain fruit quality of Japanese plums (Prunus salicina Lindl. cvs. ‘Angeleno’, ‘Fortune’ and ‘Tegan Blue’) following 25 d and 40 d cold storage (1 °C) was evaluated. Plum fruit were sprayed with different solutions of 2 μM BC (i.e., aqueous solutions containing distilled water only or 5 % ethanol or 0.02 % Tween® 20 or 5 % β-cyclodextrin) or fumigated with 1 μM BC at ambient temperature. Plum fruit without any treatment were regarded as control. Regardless of the cultivars tested, all formulations of …

Effect Of Ph And Heat Treatment On Physicochemical And Functional Properties Of Spray-Dried Whey Protein Concentrate Powder, Thao M. Ho, Jinlei Zhu, Nidhi Bansal, Mary C. Boyce, Thao T. Le
Research outputs 2014 to 2021
Effects of pH and heating on deamidation of whey protein concentrate (WPC) solution and functional properties of resultant spray-dried WPC powder were investigated. Temperature and heating time affected deamidation rates with the highest reactivities for WPC solutions heated at 120 °C for 15 min and 145 °C for 120 s. Deamidation sites were pH dependent: pH 3 induced more glutamine deamidation; pH 10 induced more asparagine deamidation. The functional properties of spray-dried WPC powders were also pH dependent. WPC solution adjusted to pH 3 and heated at 145 °C for 120 s (prior to spray drying) exhibited a reduction in …

The ‘Granny Smith’ is a commercial apple cultivar in Western Australia and popular in the apple world as well, for its unique green colour and flavour. The effects of two new ethylene antagonists namely 1H-cyclopropabenzene (BC) and 1H-cyclopropa[b]naphthalene (NC), as well as 1-methylcyclopropene (1-MCP) on ethylene production, rates of respiration and fruit quality were investigated in controlled atmosphere (CA) stored ‘Granny Smith’ apple. The apple fruit were fumigated with 1 μM BC (0.09 μL.L−1) or 1 μM NC (0.14 μL.L−1) or 18 μM (1 μL.L−1) 1-MCP for 18 h at room temperature (20 ± 2 °C and 65 ± 5% …

The seed coat of the legume lupin which is rich in insoluble dietary fibre is a major by-product in human food applications. Extrusion cooking has been demonstrated to increase desirable soluble dietary fibre in the Australian sweet lupin seed coat. In this study, processing condition of twin-screw extrusion cooking was optimised using a central composite rotatable design to increase soluble dietary fibre in lupin seed coat from 44.17 g/kg up to 113.69 g/kg dry basis. The high levels of polyphenols in the seed coat were retained. The optimal extrusion conditions which achieved maximum levels of soluble dietary fibre, total free …

The effects of two new ethylene antagonists namely 1H-cyclopropabenzene (BC) and 1H-cyclopropa[b]naphthalene (NC), as well as 1-methylcyclopropene (1-MCP) on ethylene production and fruit quality of Cripps Pink and Granny Smith apple in ozonized cold storage, were investigated. When compared to control, Cripps Pink fruit fumigated with BC and NC exhibited significantly lowest ethylene production and respiration, whilst the Granny Smith fruit treated with 1-MCP exhibited lowest ethylene production followed by NC and BC treatments. Application of ozone in cold storage maintained higher levels of sugars but elevated ethylene production in both the apple cultivars. No significant interaction was recorded between …

Shiga toxigenic E. coli (STEC) are an important cause of foodborne disease globally with many outbreaks linked to the consumption of contaminated foods such as leafy greens. Existing methods for STEC detection and isolation are time-consuming. Rapid methods may assist in preventing contaminated products from reaching consumers. This proof-of-concept study aimed to determine if a metabolomics approach could be used to detect STEC contamination in spinach. Using untargeted metabolic profiling, the bacterial pellets and supernatants arising from bacterial and inoculated spinach enrichments were investigated for the presence of unique metabolites that enabled categorization of three E. coli risk groups. A …

© 2021 Elsevier Ltd Insects have been consumed by people for millennia and have recently been proposed as a complementary, sustainable source of protein to feed the world's growing population. Insects and crustaceans both belong to the arthropod family. Crustacean (shellfish) allergies are common and potentially severe; hence, the cross-reactivity of the immune system with insect proteins is a potential health concern. Herein, LC-MS/MS was used to explore the proteome of whole, roasted whole and roasted powdered cricket products. Eight protein extraction protocols were compared using the total number of protein and distinct peptide identifications. Within these data, 20 putative …

Lysine is the most limiting essential amino acid in cereals, and efforts have been made over the decades to improve the nutritional quality of these grains by limiting storage protein accumulation and increasing lysine content, while maintaining desired agronomic traits. The single lys3 mutation in barley has been shown to significantly increase lysine content but also reduces grain size. Herein, the regulatory effect of the lys3 mutation that controls storage protein accumulation as well as a plethora of critically important processes in cereal seeds was investigated in double mutant barley lines. This was enabled through the generation of three hordein …

Gluten related disorders, such as coeliac disease, wheat allergy and baker's asthma are triggered by proteins present in food products made from wheat and related cereal species. The only treatment of these medical illnesses is a strict gluten-free diet; however, gluten-free products that are currently available in the market can have lower nutritional quality and are more expensive than traditional gluten containing cereal products. These constraints have led to the development of gluten-free or gluten-reduced ingredients. In this vein, a non-GMO wheat flour that purports to contain “65% less allergenic gluten” was recently brought to market. The present study aims …

Human-wildlife interactions have developed since the agricultural revolution that occurred 10,000 years ago, and the expansion of commensal species’ geographical distribution led to conflicts that prompted humans to adopt a wide range of control methods for pest species (Horvitz, Wang, Wan, & Nathan, 2017; Riyahi et al., 2013; Saraswat, Sinha, & Radhakrishna, 2015). The order Rodentia is characterised by a high number of successful invaders, which humans have attempted to manage with the use of anticoagulant rodenticides (ARs) since the 1940s (Capizzi, Bertolino, & Mortelliti, 2014; Ruiz-Suárez et al., 2014). The rise and spread of a genetic mutation that infers …
