Antioxidant Capacity, Arabinoxylans Content And In Vitro Glycaemic Index Of Cereal-Based Snacks Incorporated With Brewer’S Spent Grain, Sofia Reis, Nissreen Abu-Ghannam

Articles

Extruded snacks and breadsticks were formulated with increasing levels of brewer’s spent grain (BSG). The phenolic content increased by 4 and 7 fold with BSG addition in extrudates (40g/100g) and in breadsticks (35g/100g), respectively. Consequently, antioxidant capacity (DPPH, FRAP) also increased despite a recorded loss of phenolic compounds in extruded snacks. Arabinoxylans content increased up to 20 and 25g of BSG addition /100g of formulated extruded snacks and breadsticks, respectively. Further addition of BSG did not improve the content of arabinoxylans due to the possible formation of polysaccharide-protein complexes. Medium GI breadsticks were obtained with 35g of BSG incorporation /100g …

An Ultra-Performance Liquid Chromatoghraphy-Tandem Mass Spectrometry (Uplc-Ms/Ms) Method For The Rapid And Sensitive Determination Of Sulforaphane And Sulforaphane Nitrile In Brassica Vegetables, Laura Alvarez Jubete, Thomas J. Smyth, Juan Valverde, Dilip K. Rai, Catherine Barry-Ryan

Articles

A rapid UPLC-MS/MS method has been developed and validated for the simultaneous analysis of sulforaphane and sulforaphane nitrile from Brassica Oleracea L. This method was developed utilising an Acquity BEH C8 column with gradient elution combined with tandem mass spectrometry detection, using positive ion electrospray ionisation in multiple reaction monitoring (MRM) mode. The method was validated for linearity, sensitivity, precision, accuracy, matrix effects and recovery. The retention times for sulforaphane and sulforaphane nitrile were 0.4 and 0.6 min, respectively. The limits of detection and lower limits of quantification were 0.005 μM and 0.01 μM respectively for sulforaphane, and 0.06 μM …

Carcass Feeding For Captive Vultures: Testing Assumptions About Zoos And Effects On Birds And Visitors, Hannah Gaengler

Dissertations and Theses

Carcass feeding is a potentially controversial feeding method for zoo animals. The common assumption is that many North American zoos refrain from feeding large carcasses to their carnivorous animals because zoo visitors might not approve of this feeding method. However, since there are several species of carnivores in zoos that feed from large carcasses in nature, this food type also has the potential to be beneficial to their welfare. In intelligent and usually inquisitive scavengers like vultures, a lack of activity and behavioral opportunities could be a welfare problem in captivity; providing them with a more complex food item might …

Textural And Sensory Qualities Of Muffins Prepared With Fermented Rice Bran, Breeanna Williams, Navam Hettiarachchy, Srinivas J. Rayaprolu

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Rice is one of the most popular cereal grains in the world. Rice bran, a by-product of the rice milling process, contains an abundance of nutrients including protein, fiber, vitamin B complex, vitamin E, and other nutraceuticals. However, rice bran is underutilized in the food industry. In this project muffins were prepared with varying concentrations (2.5%, 5.0%, 7.5%, 10.0%, 15.0%, 20.0%, and 25.0%) of 60 mesh (250 µm) fermented rice bran (60 mFRB) and 80 mesh (180 µm) fermented rice bran (80 mFRB). A cappuccino muffin formulation was used as flavor for all the samples. The control sample was prepared …

Formation And Stability Of An Oil In Water Emulsion Containing Lecithin, Xanthan Gum And Sunflower Oil, Mark Traynor, Roisin Burke, Jesus Maria Frias, Edurne Gaston, Catherine Barry-Ryan

Articles

The optimisation of the formation and stability of an oil in water emulsion containing lecithin, xanthan gum and sunflower oil was evaluated using Response Surface Methodology (RSM) and nonlinear regression. The main and combined effects of three independent variables; concentration of sunflower oil (10-20% v/v), soy lecithin (1-5% w/v) and xanthan gum (0.01-3% w/v) on the responses were examined. The main objectives of the study were to model and optimise maximum emulsion storage stability and to study interactive effects of emulsion ingredient. Emulsion stability and mean droplet diameter were measured over 14 days of storage using an image processing procedure …

Sensory And Chemical Interactions Of Food Pairings (Basmati Rice, Bacon And Extra Virgin Olive Oil) With Banana, Mark Traynor, Roisin Burke, Maurice O'Sullivan, John Hannon, Catherine Barry-Ryan

Articles

The aim of this study aimed to investigate food pairings as an important sensory phenomenon in order to determine how different components in the selected food pairings affect and interact with other components. Three novel food pairings (banana and bacon, banana and olive oil, and banana and rice) were selected. A conjoint approach utilising qualitative (organic volatile analysis and descriptive sensory analysis) and quantitative (comparable semi quantitative organic volatile analysis and affective sensory tests) methods of analysis n an attempt to elucidate the success or failure of selected food pairings. Free choice profiling (descriptive sensory analysis) data was analysed using …

Dietary Antioxidant Supplementation (Economase–Bioplex) To Alleviate Adverse Impacts Of Oxidized Oil On Broiler Meat Quality: A Chemical, Textural, Enzymatic, And Proteomic Study, Rebecca Delles

Theses and Dissertations--Animal and Food Sciences

This study investigated the influence of dietary antioxidants and quality of oil on the oxidative and enzymatic properties of chicken broiler meat stored in an oxygen-enriched package (HiOx: 80% O₂/20% CO₂) in comparison with air-permeable polyvinylchloride (PVC) or skin (SK) packaging systems during retail display 2–4 °C for up to 14, 7, and 21 d, respectively. Broilers were fed a diet either with a low-oxidized oil (peroxide vale POV 23 meq O₂/kg) or with a high-oxidized oil (POV 121 meq O₂/kg), supplemented with an antioxidant pack (200 ppm EconomasE and organic minerals …

Degradation Kinetic Modelling Of Colour, Texture, Polyphenols And Antioxidant Capacity Of York Cabbage After Microwave Processing, Amit Jaiswal, Nissreen Abu-Ghannam

Articles

Vegetables as an essential component of the human diet usually undergo some type of processing before being consumed. In the present study, impact of microwave (MW) processing on various physiochemical properties of York cabbage was studied. York cabbage was processed at 400, 560 and 800W for 0 to 14 min with an increment of 2 min followed by a kinetic study for the degradation of polyphenols, flavonoids, antioxidant capacity, colour and texture were carried out. Results showed that MW processing leads to significant reductions in the texture, colour, polyphenols and antioxidant capacity. For all the MW processing power studied total …

Valorisation Of Apple Peels, Laura Massini, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan

Articles

The peels of processed apples can be recovered for further food applications. Limited information on the valorisation of this type of waste is available for cooking varieties, e.g. cv Bramley’s Seedling. Extracts from fresh or dried (oven-dried or freeze-dried) peels were obtained with solvents of different polarity (aqueous acetone or ethanol) and assayed for their total phenolic content and antioxidant capacity; their antiradical power was compared to herb extracts. The dried peels were also characterised as bulk powders by assessing their nutritional value and total phenolic content. High amounts of ascorbic acid (up to 4 mg/g, dry weight) and polyphenols …

A Critical Examination Of Food Technology, Innovation And Teacher Education : A Technacy Genre Theory Perspective, Angela Frances Turner

Dr Angela Turner

There are many and varied forces that shape food technology curriculum, but two that emerge as significant and of specific interest to this research are the perceptions of food technology education and economic trends that influence food technology. The broad goal was to examine the extent to which food technology in secondary schooling is well placed to meet emerging policy and economic demand for food innovation expertise in the industry. With both the school sector and the professional sector each asserting that their respective perceptions of Food Technology was correct, a method for clarifying and classifying the nature of the …
