Composition and Consumer Acceptance of Frozen Yogurts Utilizing Whey Protein Concentrates
<p>It has been said that frozen yogurt is one of the best new products that has happened to American enterprise, consumer eating habits, and the dairy industry (Kimbrill et al., 1990). Frozen yogurt was introduced as a new product in the early 1970s and has come a long way since its appearance …

Application of bulk nanobubbles in ultrafiltration and spray drying of dairy concentrates
Milk protein concentrates (MPC) are ideal dairy ingredient to provide nutritional and functional benefits in high-protein dairy and food products. However, one of the key challenges encountered by the MPC manufacturers during the spray drying is the high viscosity after ultrafiltration and …

Preparation of juice concentrates by nonthermal processing technologies: a multiple hurdle approach
The conventional preparation of juice concentrates is by thermal evaporation. However, some quality attributes, nutrients, bioactive components, and other volatile compounds are degraded due to prolonged exposure to high temperatures. This leads to the investigation of the membrane separation …

Development and processing of intermediate moisture, shelf-stable condensed sweetened soy concentrates
Several model systems were designed to develop intermediate moisture shelf-stable products. These systems were designed using whole soy and desludged soy slurries. Four nutritive sweeteners namely sucrose, glucose, fructose and sucrose:glucose (7:3) were the major component and the soy solid …

Environmental mineralogy of gold recovery from refractory gold-arsenic-bearing Bakyrchik concentrates
… Au recovery from double refractory Au-As-bearing concentrates has been developed, allowing recovery of 97% of Au, and the conversion of up to 95% As into iron-arsenic alloy. Fe-As alloy can contain up to 40% As, and do not require further solidification/stabilisation prior to disposal. The method …

Evaluation of processing options for the treatment of zinc sulphide concentrates at Skorpion zinc
… With the abundant availability of zinc sulphide concentrates regionally the life of the operation may be extended by processing these concentrates. The leach kinetics of zinc sulphides is vastly slower than oxides, preventing the processing of zinc sulphides using the existing process, under …

Production of Protein Concentrates from Brewer's Spent Grain via Wet Fractionation and Enzymatic Purification
Brewer's spent grain (BSG) is a main by-product of beer manufacturing and is rich in nutrients including 15-30% protein, making it a potentially valuable protein source for human food. Current challenges of extracting protein from BSG include low yields and high manufacturing costs, but the rising …

Production of Selenium-enriched Wheat Protein Concentrates and Isolates for Enhancement of Wheat Flour Functionality
… processing efforts. Se-fortified wheat protein concentrates (WPC, gluten) and isolates (WPI) can be used for fortification of weak flours. Our earlier studies determined that up to 77% of the grain Se was retained in the endosperm. Rheological properties of the WPC, WPI and flour blends may …

Behaviour of Critical Metals During Smelting of Copper Concentrates from Olympic Dam Plant, South Australia
This thesis provides a comprehensive characterisation of slags produced during direct-to-blister copper smelting at Olympic Dam, South Australia. It aims at measuring and interpreting the content and behaviour of selected critical elements in slags,: rare earths elements (REE), Co, Ni, Ti, Nb, and …

Characteristics of heat transfer fouling of thin stillage using model thin stillage and evaporator concentrates
The US fuel ethanol demand was 50.3 billion liters (13.3 billion gallons) in 2012. Corn ethanol was produced primarily by dry grind process. Heat transfer equipment fouling occurs during corn ethanol production and increases the operating expenses of ethanol plants. Following ethanol distillation, …

Color and Structural Modifications of Alkaline Extracted Sunflower Protein Concentrates and Isolates Using L-Cysteine and Glutathione
<p>Sunflower protein can be extracted at alkaline pH with sulfites or organic solvent de-phenolization of sunflower seed meals if greening is unwanted. This greening is promoted at alkaline pH when chlorogenic acid (CGA) oxidizes and reacts with free amine groups from amino acids, such as lysine. …

A study of chemolithoautotrophic bacterial rhodanese, and its potential contribution to cyanide wastage during cyanidation of biooxidized concentrates
Refractory gold-bearing metal-sulfide ores and concentrates can be successfully and economically treated by biooxidation prior to cyanidation. However, one of the major drawbacks of the biooxidation process is the excessive consumption of cyanide during the gold dissolution process. The largest …

Development of an unsteady state model for the tank bioleaching of sulphide mineral concentrates in flow reactor systems
In this thesis, it is hypothesized that in bioleaching flow reactor systems, high reaction rate regions exist that can be maintained by application of biological stress trajectories. Reactor models are developed for the purpose of optimising plant operation, understood here as maximising the …

PROPERTIES OF AQUEOUS-ALCOHOL-WASHED PROTEIN CONCENTRATES PREPARED FROM AIR-CLASSIFIED PEA PROTEIN AND OTHER AIR-CLASSIFIED PULSE PROTEIN FRACTIONS
Pea protein concentrates were prepared from air-classified pea protein by aqueous-alcohol (ethanol or isopropanol) washing. Response surface methodology (Box Behnken design) was used to create mathematical models to explain quantitatively the relationship between treatment combinations (aqueous …
