Ingredient Development using a Pilot-Scale Tall-Form Spray Drier
End of Project ReportThe main objectives of the project were to establish relationships between process variables
and product physicochemical/functional characteristics in the course of processing and
drying new dairy-based ingredients such as high-fat and protein-rich products in regular and
agglomerated forms. By establishing processing protocols, R&D users of the ingredient
drying facilities of Moorepark Technology Ltd may be able to predict the process variables
necessary for desired end-product specifications to be achieved, and thus make
experimentation more efficient and cost effective, as well as facilitate small scale production
runs and sample preparation for market development purposes. Particular emphasis was
placed on the development of high fat cream and fat-filled powders, flavour-delivery
systems and protein-enriched ingredients. The major achievement of this project is that it is now possible to confidently select the
appropriate processing conditions during the spray drying of ingredients in order to attain
desired end-product specifications. Based on the use of the newly-installed Tall-form drier,
the project succeeded in correlating the effects of process parameters of this technicallyadvanced
pilot plant with the physicochemical properties of powders containing varying fat
(20-80%) and protein contents. In general, the physicochemical characteristics of fat-filled
and cream-filled powders with similar fat contents were similar except for higher solubility
index values (range 0.1-0.6) in the case of the former particularly in the range 26-28% fat.
Furthermore, the free fat content of powders may now be controlled much more precisely
using an appropriate combination of total fat, atomiser nozzle selection and post-drying
blending.Department of Agriculture, Food and the Marin
Organic-Conventional Dairy Systems Trial in New Zealand: Four Years’ Results
The Organic-Conventional Comparative Dairy Systems trial at Massey University began in August 2001, and the organic farmlet achieved certification in August 2003. The trial is unique because it is the only comparative grassland-based open grazing dairy study in the world. The organic and conventional systems are managed individually according to best practice, and both are intensively monitored for production, animal health, and environmental impacts. The systems remained similar for the first two years, but began to diverge in the third and fourth years. Production has been 10-20% lower on the organic farm, but environmental impacts appear to be less than on the conventional unit, and net incomes would be similar given a 20% price premium for the organic product. Animal health issues have been manageable on the organic farmlet, and not too dissimilar from the conventional farmlet. Full results after four years of the trial will be available and presented at the conference
Care, Community and Curriculum: a Case Study of an Academic Professional Development Programme
In March 2020, teaching and learning (T&L) in higher education pivoted online and in 2021 the disruption to traditional formsofteaching, learning and assessment continues. Like many other academic development programmes, our PG Cert programme pivoted online effectively and efficiently. Programme evaluation data (June 2020)reported that modelling of online teaching and learning within our programme helped lecturers teach online, facilitate peer interaction among their students and assisted informed change in assessment practices to suit the online context.At the heart of our programme’s ethos lies a commitment to community building among students. However, the art of gathering is more than bringing students into a virtual room. Design and careful planning is necessary to elevate a learning experience from modes of presence to participation and to foster a sense of belonging for students within that learning environment. Also given the Pandemic context, a period where the effects of isolation from other people and society were felt acutely, the programme team felt it vital that time was designated for check-ins with participants of the learning environment. Bali (2020) advocates a Pedagogy of care, an approach that demonstrates a genuine concern for students’ wellbeing and life experiences

Bali (2020) advocates a Pedagogy of care, an approach that demonstrates a genuine concern for students’ wellbeing and life experiences. This exploratory case study examines how the pivot to online teaching on our Postgraduate (PG) Certificate in University Learning and Teaching has impacted on teaching practices of academic staff across the disciplines undertaking the programme. We wish to investigate if and how community building and care was subsequently implemented in the learning environments of academic staff who undertook the PG Cert. Secondly, to inspect what T&L practices, with a focus on the pedagogy of care, that might remain in place in a post pandemic university. Thirdly, to investigate if fully online learning is suitable and viable for the PG Certificate which values community, professional relationships and shared practice. Lastly, this disruptive change to online teaching necessitates the investigation of the future teaching development needs for lecturers teaching in online and blended spaces. Also, in our context, as an emerging technological university, through our experiences and research we propose some recommendations for the university to consider at a strategic level in support of the development of teaching and learning practice in a post digital higher education environment

VARIATION IN EROSION/DEPOSITION RATES OVER THE LAST FIFTTY YEARS ON ALLUVIAL FAN SURFACES OF L. PLEISTOCENE-MID HOLOCENE AGE, ESTIMATIONS USING 137CS SOIL PROFILE DATA, AMARGOSA VALLEY, NEVADA
Variations in erosion and deposition for the last fifty years (based on estimates from 137Cs profiles) on surfaces (Late Pleistocene to Late Holocene in age) making up the Fortymile Wash alluvial fan south of Yucca Mountain, is a function of surface age and of desert pavement development or absence. For purposes of comparing erosion and deposition, the surfaces can be examined as three groups: (1) Late Pleistocene surfaces possess areas of desert pavement development with thin Av or sandy A horizons, formed by the trapping capabilities of the pavements. These zones of deposition are complemented by coppice dune formation on similar parts of the surface. Areas on the surface where no pavement development has occurred are erosional in nature with 0.0 +/- 0.0 cm to 1.5 +/- 0.5 cm of erosion occurring primarily by winds blowing across the surface. Overall these surfaces may show either a small net depositional gain or small erosional loss. (2) Early Holocene surfaces have no well-developed desert pavements, but may have residual gravel deposits in small areas on the surfaces. These surfaces show the most consistent erosional surface areas on which it ranges from 1.0 +/-.01 cm to 2.0+/- .01 cm. Fewer depositional forms are found on this age of surface so there is probably a net loss of 1.5 cm across these surfaces. (3) The Late Holocene surfaces show the greatest variability in erosion and deposition. Overbank deposition during floods cover many edges of these surfaces and coppice dune formation also creates depositional features. Erosion rates are highly variable and range from 0.0 +/- 0.0 to a maximum of 2.0+/-.01. Erosion occurs because of the lack of protection of the surface. However, the common areas of deposition probably result in the surface having a small net depositional gain across these surfaces. Thus, the interchannel surfaces of the Fortymile Wash fan show a variety of erosional styles as well as areas of deposition. The fan, therefore, is a dynamic system that primarily responds to the incising of the channels into the upper fan surface, and the development of protecting desert pavements with time
Influence of addition of plasmin or mastitic milk to cheesemilk on quality of smear-ripened cheese
peer-reviewedSmear-ripened cheese varieties are characterised by the growth of a smear culture, containing
predominantly Brevibacterium linens, on the cheese surface during ripening. In such cheese,
considerable zonal differences in biochemistry of ripening exist, due to moisture loss from, and
growth and metabolic activity of smear microflora at, the cheese surface. In this study, the effects of
adding exogenous plasmin or small amounts of mastitic milk to good quality milk on the quality of
smear-ripened cheese made subsequently was examined. Addition of plasmin did not influence
cheese composition immediately after manufacture, but slightly decreased the rate of moisture loss
during cheese ripening. Plasmin activity decreased during the early stages of ripening, but subsequently
increased towards the end of ripening, perhaps due to changing pH conditions in the cheese.
Addition of plasmin increased rates of primary proteolysis in cheese, as measured by levels of pH 4.6-
soluble N and urea-PAGE, although production of later products of proteolysis appeared less affected.
Addition ofmastitic milk had largely similar effects to addition of exogenous plasmin, which
may reflect a high content of plasmin or plasminogen activators in such milk. Overall, changes in
milk quality and enzymology appear to influence the quality of smear-ripened cheese
