The application of visible/near-infrared hyper-spectral analysis to monitor the quality of frying oil and fried breaded chicken nuggets was investigated. / Partial least squares (PLS) calibration models were developed to predict the acid value, total polar components and viscosity of heated oils with different ratios of hydrogenation. Coefficient of determination (R2) and root mean square error (RMSE) were calculated to assess the performance of each model. Results of the study demonstrated good prediction ability of the calibration models for the quality parameters with R2 values of over 0.92. / The second study was based on developing calibration models for prediction of moisture and fat contents of fried breaded chicken nuggets with different levels of moisture and fat contents. Performing the same procedure for evaluation of the PLS calibration models, results of the study demonstrated that moisture and fat contents of fried breaded chicken nuggets could be predicted with R2 values of 0.92.

Underpinning most anthropological definitions of culture is the concept of the cultural transmission and diffusion of learned behaviour. Anthropological works generally emphasise the outcomes of this transmission rather than the processes, in part because the mechanisms are either ongoing or practically invisible. Recipes have proved a unique tool for tracking cultural transmission because of their inherent precision and characteristically datable contexts. This study uses recipes to explore the many paths of transmission and diffusion of culinary knowledge. The period under review is from the eighteenth to the twentieth centuries and the focus is on British culinary traditions up-to and after, their transfer to New Zealand. It was found that culinary knowledge was disseminated around New Zealand through both formal and informal mechanisms. Formal transmission involved teachers, their school cookery classes and published teaching manuals, all of which played a major role in training school children to cook the dishes served at family meals. In contrast, informal publications such as cookery columns in magazines and newspapers were transmitting recipes for more fashionable dishes, especially baking, and these incorporated mechanisms that promoted innovation more than retention of traditional recipes. The significant role of material culture in cookery provided another pathway of transmission through appliance recipe books which translated established recipes into a form that could be made with the new technology, thereby preventing their disappearance from the culinary repertoires of cooks. It was established that community cookbooks, a common means of fund-raising, were a significant means of diffusing culinary information. The cookbooks produced by such efforts demonstrated change over time in their recipe content, especially if published as a series and such publications were tangible repositories of the cookery knowledge within the community. This study examined not only the pathways of culinary transmission but also the contexts in which it occurred. These circumstances were found to be influential in determining eventual acceptance or rejection of cookery knowledge and recipes, and provide valuable insights into processes of culture change.

This thesis examines the shift from traditional on-site industry education (apprentice style learning) to tertiary education in academically-centred institutions, with particular emphasis on professional culinary education. With the deceptively seamless transition of numerous crafts and trades from their traditional apprentice/journeyman training and education schemes, into the tertiary education sector - from the late 1960s up until today - a crack had been created in the education process. The government had acknowledged that the possible 'confusion' and 'drop back' in traditional training schemes and apprenticeships had, to some extent, been a case of confusion or misinterpretation on the part of trade and industry and new trainees. Particularly, when the general comprehension of the 'newly' altered Education Act, New Apprenticeship Act and government-promoted shift of autonomous industry bodies to a centralised State controlled system had been largely ineffective, there was an observable decline in the traditionally mentored and educated crafts and trades. The investigation extends beyond the recent 'symptoms' of changing government Acts, extensively developing (global) tertiary education and evolving industry education responsibility to explore the deeper influences and controls of change which have brought us to where we are today. This exploration will cover a diversity of education history, government policy, industry renovation and significant world events which have changed the path of the modern journeyman and professional craft and trade education. Within the New Zealand context, little research has been found or published on this particularly involved theme [the Modern Journeyman and professional culinary education], which, by its absence has contributed to a wide chasm of unanswered enquiries and uncertainties, which now needs to be investigated. This treatise explores three key areas of 'power and control' within the arenas of politics, education and industry education. These are considered through the multi-perspective lenses of critical social science, existentialism and postmodernism. Specific attention is paid to the practical aspects of the evolving (culinary) Journeyman and the seemingly repetitive patterns of 'power and control' that have emerged from the multifarious disciplines and time-frames. Throughout the development of Western European education and the advancement of craft and trade (knowledge and practices), there has been a question of value, ownership and 'privilege' attached to who, how, where and what can be taught and learnt. And in many cases the State has either stepped in to regulate the process - as a matter of civil duty, or has taken over the process - as a form of social and ideological control. In the case of the Culinary Journeyman, the New Zealand tertiary system and the shifting authorities of professional knowledge and practice, the price which may eventually be extracted for the targeted control of education practice (mentored/apprenticed learning) and professional knowledge development, may be more than the cost of an admission to a professional tertiary cookery course in the future.

Doctor of Philosophy / Department of Animal Sciences and Industry / Terry Houser / One experiment was conducted to determine the collagen and adipocyte characteristics in pork belly fat with different iodine values (IV) and if these factors contribute to belly firmness. An additional two experiments were conducted to create an objective method to score bacon distortion during cooking and to determine how IV and cooking method contribute to bacon distortion. Experiment 1 sorted pork bellies (n=72) into three IV categories: High 76.5 g/100g, Intermediate 70.5 g/100g, and Low 64.9 g/100g. Belly characteristics and firmness were measured before processing into bacon. After processing, 3 bacon slices were selected from the belly and analyzed for histochemistry and collagen analysis. No differences were observed between belly characteristics, while High IV bellies showed softer bellies. Adipocyte characteristics remained unchanged between IV groups. High IV bellies showed greater amounts of collagen. Experiment 2 cooked bacon slices (n=585) on three different appliances (griddle, microwave, and oven) and scored the resulting distortion using a subjective scale. Raw and cooked bacon characteristics were measured to determine which response variables contributing to distortion. Bacon slices were removed from 6 different locations within each belly sampled. Two distortion measurements were created to objectively describe distortion response (crest frequency and bacon distortion index. Subjective distortion scores, crest frequency, bacon distortion index, and raw and cooked bacon characteristics were shown to change between locations of the belly. Accuracy of predictive equations developed to predict distortion scores were low. Experiment 3 evaluated how IV interacts with cooking methodology to influence cooking characteristics, fat quality and distortion of bacon. Bacon slices (n=300) were organized into two IV categories, Low (61.52 to 65.54 g/100g) and High (78.83 to 85.34 g/100g) and cooked using three different appliances (oven, microwave, and griddle). Bacon from the Low IV group had the greatest amount of fat. Cooking bacon on a griddle showed the greatest distortion scores, while the oven produced bacon with the lowest distortion scores. Bacon with higher IV produced bacon with increased distortion scores. Bacon from the High IV group showed smaller cooked dimensions than the Low IV bacon. Neither cooking method nor IV level affected the cooked fatty acid composition.
