Why do you want to study this course or subject?
My interest in dairy began with a thermos flask, a thermometer and a lot of failed yoghurt. I wanted to know why one batch set firmly and the next stayed thin, and reading around the problem took me into incubation temperatures, starter culture ratios and the way heat treatment changes whey proteins so they can hold water in a gel. What started as kitchen trial and error turned into a genuine curiosity about the science that sits behind an ordinary fridge shelf. Milk interests me because it is both a biological fluid and an industrial raw material, and because so much of what we eat depends on controlling it precisely: pasteurisation schedules, homogenisation, acidification rates, cold chains. I would like to study dairy technology rather than food science in general because I am drawn to that specificity. I find it satisfying that small changes in pH or calcium availability decide whether a curd is rubbery or crumbly, and that these are measurable, adjustable things rather than matters of luck. I am also interested in the practical pressures the industry faces: reducing waste from whey and other by-products, cutting the energy used in drying and chilling, and producing consistent products from milk that varies with season and feed. A degree that combines chemistry, microbiology, processing and quality management suits how I like to work, moving between understanding a mechanism and making something work reliably. In the long term I would like to work in product development or quality assurance for a dairy processor, and I want the technical grounding to contribute properly rather than just follow a specification sheet.
How have your qualifications and studies helped you to prepare?
My A levels in Biology, Chemistry and Geography have each contributed something I expect to use. Chemistry has been the most directly relevant: equilibria, buffers and rates of reaction gave me the vocabulary to understand why acidification during fermentation behaves the way it does, and practical work on titrations and calibration taught me to be careful about sources of error rather than hopeful about results. In Biology I enjoyed the microbiology and enzyme topics most, particularly how temperature and pH affect enzyme activity, which made the logic of pasteurisation and of rennet coagulation much clearer. My coursework investigation looked at the effect of substrate concentration on enzyme activity, and writing it up taught me to plan repeats properly and to be honest about the limits of my data. Geography has been less obvious but useful in a different way: units on agriculture, water use and food supply chains pushed me to think about dairy as a system stretching from grassland management to retail, and about the environmental trade-offs involved in different production models. I have kept up independent reading alongside my courses, including Harold McGee's On Food and Cooking, which I return to for its explanations of milk proteins and emulsions, and a dairy processing handbook borrowed through my college library that introduced me to plate heat exchangers and separators. I am now more comfortable reading technical diagrams than I was a year ago. Mathematics is not one of my A levels, but I have worked deliberately on the quantitative side, practising unit conversions, mass balance style problems and percentage composition calculations so that I can handle the numerical parts of a technology degree confidently.
What else have you done to prepare outside of education, and why are these experiences useful?
For the past two years I have worked most Saturdays in my aunt's farm shop café, serving customers, restocking the chiller and helping with the cleaning schedule at the end of the day. The shop sells milk, butter and cheese from producers nearby, and handling that stock has taught me practical things a textbook would not: how quickly cream picks up off odours, why date rotation matters, how a chiller temperature log is actually kept and what happens when a delivery arrives warmer than it should. I have also had many conversations with the cheesemaker who supplies us, who explained why her batches vary between spring and autumn milk. At home I make yoghurt and soft cheese regularly and keep a notebook of incubation times, temperatures and outcomes, which has made me realise how much repetition it takes before a method is genuinely reliable. My most stubborn project has been a set curd yoghurt that does not weep whey, and I have gradually improved it by holding the milk longer at a higher temperature before cooling, though I know the underlying protein chemistry only roughly and want to learn it properly. Outside work and the kitchen, I play in a college netball team, where being goalkeeper has taught me to concentrate for long stretches and communicate quickly under pressure. I also volunteer fortnightly at a community lunch club, mostly washing up, laying tables and sitting with people who come on their own. It is unglamorous, but it has made me better at noticing when someone needs help before they ask, and it keeps me aware that food is about more than specification. Together these commitments have taught me to organise my week, keep to standards when nobody is checking, and stay patient with problems that take several attempts to solve.
