Ruminant production systems are major contributors to greenhouse gases emissions, with animal feeding practices being the main cause for methane and nitrous oxide’s release. Although feeding animals forages has been proven to be more sustainable, traditional ryegrass monocultures still require a lot of input (e.g., fertilisers and pesticides). Multi-species swards, consisting of different swards, such as grasses, forage legumes and herbs, need less management and fertiliser, produce more dry matter, and also add a variety of phytochemicals into the animal diet. In particular, polyphenols have been associated with a positive impact on animal health and productivity. However, data on the …

Cold plasma (CP) is an effective strategy to alter the limitations of biopolymer materials for food packaging applications. Biopolymers such as polysaccharides and proteins are known to be sustainable materials with excellent film-forming properties. Bio-based films can be used as an alternative to traditional plastic packaging. There are limitations to biopolymer packaging materials such as hydrophobicity, poor barrier, and thermos-mechanical properties. For this reason, biopolymers must be modified to create a packaging material with the desired applicability. CP is an effective method to enhance the functionality and interfacial features of biopolymers. It etches the film surface allowing for better adhesion …

ClO2 as an antimicrobial gas in the headspace of produce package is a relatively novel approach. Gaseous ClO2 is more effective than aqueous ClO2 and can be used in the headspace of fresh food packages. ClO2 gas can diffuse into product surfaces and films. As an oxidizer, it can react with and change polymeric package components, possibly affecting the product’s shelflife.
This research studied effects of ClO2 gas treatments on produce packaging materials (APET, two PE types, Nylon). The treatment group (with ClO2) and the control group (without ClO2) of packaging …
Evaluating The Efficacy Of Germination And Fermentation In Producing Biologically Active Peptides From Pulses, 2022 University of Nebraska-Lincoln
Evaluating The Efficacy Of Germination And Fermentation In Producing Biologically Active Peptides From Pulses, Ashley Newton
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Recently, there has been a profound increase in demand of plant-based proteins, especially pulse proteins. However, pulses contain high concentrations of antinutritional factors that hinder the digestibility of proteins. Processing techniques such as enzymatic hydrolysis, microbial fermentation, and physical processing modulate nutritional quality and functionality of pulses. Processing also releases peptides from parent proteins that exhibit health-beneficial bioactivity against various disease risk factors. In this study, germination, gastrointestinal digestion, and microbial fermentation were evaluated to determine the nutritional quality and release of bioactive peptides during and after processing.
