Item Open Access Quality enhancement of Barramundi kamaboko using vortex fluidic device modified starch and fish gelatin(Frontiers Media SA, 2024-11-01)Introduction: Prime quality kamaboko (cooked surimi) is produced from Alaska pollock. The main challenge of using cheaper fish fillets, including Barramundi, is achieving similar textures. Methods: Combined with fish gelatin, modified starch by vortex fluidic device was used to enhance the quality of kamaboko made from Barramundi. Results: Modification by a continuous flow vortex fluidic device (VFD) significantly reduces the size of particles of starch relative to conventional homogenization. Blending this VFD-modified starch with fish gelatin resulted in a well-organized cross-linked matrix compared to products manufactured from homogenization modified starch. This led to higher gel strength of the former (1,708.32 g/cm² ) relative to the latter (832.56 g/cm² ). Mixing different proportions of fish gelatin and VFD-processed starch to make Barramundi kamaboko (5, 10, and 15%), yielded a product with greater chewiness relative to Alaska pollock kamaboko. Sensory evaluation indicated that the 5% product was optimal and the 15% product with the highest chewiness (56.10 N) was the least favorable. Discussion: These results clearly indicate the potential of VFD processed starch, blended with fish gelatin to enhances the quality of kamaboko.Item Restricted The integration of Te Ao Māori in marketing: Perspectives from Māori marketing practitionersCombining culture and business in a way that is inherently Māori not only creates opportunities for Māori to give back to their communities; it is also good for business itself (Ka'ai, Smith, Haar, & Ravenswood, 2019; UniServices, 2022). Marketers are increasingly using Māori cultural elements in their practices; consider Whittaker’s special edition Miraka Kirīmi (creamy milk) chocolate to celebrate Te Wiki o te Reo Māori (Māori Language Week) (Whittaker’s, 2023). Consequently, it is of interest to explore: What are Māori marketing practitioners’ perspectives and experiences of using Māori cultural elements in their practice? Exploratory interviews with six Māori marketing practitioners were conducted kanohi-ki-te-kanohi (in person) or virtually. The research employed kaupapa Māori (Māori ideology) principles and a wānanga approach adapted from Mahuika & Mahuika (2020) through interactive kōrerorero (conversations). This included karakia (prayers), pepeha (Māori introductions), whakawhanaungatanga (relationship building), and kai (food) (kanohi-ki-te-kanohi only). Interviews were transcribed and analysed for common themes. When defining Māori cultural elements, most participants used Te Ao Māori (the Māori worldview) as their guiding framework. “For me, it's everything…It’s stepping back and viewing Te Ao Māori as a whole”. All participants embraced Te Ao Māori in their own practice and employed a consultation process, often with kaumātua (respected elders). The importance of relationships and whakapapa (genealogy) was emphasised. In terms of use by non-Māori, many participants were broadly comfortable with it, if those using it were also considerate of Te Ao Māori and tikanga.“I will always support and embrace anyone that using multicultural elements if they also have been through that [Te Ao Māori and tikanga] journey themselves”. Personal cultural journeys affected the level to which participants were comfortable with the integration of Māori cultural elements in their practice. All participants seeking further education opted for Te Reo Māori (Māori language) and mātauranga Māori (Māori knowledge), as opposed to marketing. The widespread use of Māori culture, when done well, benefits Māori communities (Roskruge, Morrison, & Maxwell, 2017). In recent years, more non-Māori organisations, like Whittaker’s, have sought to incorporate Māori cultural elements into their branding and external communications. The key to protecting this cultural taonga (treasure) is recognising efforts that support Māori, while calling out misuse. This research adds to the literature by contributing Māori marketing practitioners' perspectives on the use of Māori culture in practice, and supports rangatiratanga (sovereignty) by encouraging commercial efforts to revitalise, and preserve, Māori culture.Publication Open Access Lucerne species and strains(Lincoln College, 1957-03)During the course of a tour in 1954 I had the opportunity of observing some of the investigations being carried out with lucerne in Britain, Holland, France, United States and Canada. These observations were made because of the increasing importance of lucerne in drier districts of New Zealand. The area has roughly followed the years of the century, being approximately 20,000 acres in 1920, 32,000 acres jn 1930, 40,000 acres in 1940 and 50,000 acres in 1950. Since then, however, the area has increased to 90,000 acres in 1954. This increase has been made possible by a clearer understanding of the needs of the plant and has been made necessary by increased livestock production. A similar change has occurred in England and Wales where the former area of approximately 30,000 aeries recently rose to 112,000 acres. The increasing use of this plant in the United States has been phenomenal, the area changing from two million acres in 1900 to 10 million by 1925 and 19 million by 1952-40 per cent. of the world area. Further, they believe they have only started. If the plans of the plant breeders of Canada are achieved the change there could be even more startling. From information to hand from Spain, Palestine and Italy it appears that increased acreages of lucerne are fairly general. Why? Perhaps the two reasons given forthe increased area in New Zealand are of general application, but there is a third reason, equally important, and that is the choice of suitable strains. This reason becomes more and more important as lucerne cultivation is expanded from more suitable to less suitable environments.Publication Open Access Fertilisers, lime and farm production in New Zealand, 1900-1952(Lincoln College, 1957-05)A quantitative analysis of some official agricultural statistics for the period 1900-1952, has established some trends in fertiliser materials imported, lime produced locally, and the major items of farm production. Pastoral production has been defined as the sum of the protein equivalents contained in wool on a greasy basis, meat on a carcase weight basis, and dairy produce at a milk-at-the-pail basis. Farm production has been defined as pastoral production plus the protein equivalents contained in cash crops.Publication Open Access Loss and damage in potatoes(Lincoln College, 1959-04)The work of this survey over three seasons has involved an inspection of a sample of Canterbury crops during the lifting period (May-June), inspection of farm consignments during grading in produce stores, and observations on aspects of transportation. The problems to be discussed are less those primarily associated with loss of production to farmers, viz., virus and other diseases that limit yield, but rather more the issues that relate to blemishes or defects in the appearance of marketed produce. Of these, certain diseases, notably scab and tuber rot (Blight) are important but, in addition, mechanical damage to a perishable commodity appears to be of particular concern during the handling of the Canterbury crop.
