The Effects and Desirability of Utilizing Dried Whey in Selected Food Products

Robinson, Katherine P. 01 May 1971 (has links)
The effects and desirability of utilizing dried whey in pie crust, muffins, and beef gravies were studied using taste panel evaluations and objective testings. In pas try the addition of whey caused significant changes. As the whey level increased to 10 percent of the flour weight, the crust became browner during baking and the shortometer recorded an increase in tenderness. The taste panel noted as whey levels increased to 10 percent and above that the color became yellow instead of creamy white; the flavor became undesirable; and pastry became less tender and flaky. Whey significantly increased the desirability of muffins by enhancing the golden brown color, producing a more desirable flavor and increasing the tenderness of the muffins. Whey enhanced the flavor of fresh gravies. The consistency and mouth feel rated undesirable in milk gravies when whey was added. However it was more acceptable in gravies using water as the liquid. High whey levels prevented excessive retrogradation, but had adverse flavor effects.

Determination of antioxidant and total phenolic content of Pueraria lobata and evaluation of novel food products containing kudzu

Burney, Sandra Lynn Blalock 01 May 2010 (has links)
Kudzu (Pueraria lobata) is an edible vine from the legume family native to China but growing prolifically throughout the southeastern United States. Legumes are abundant in the beneficial compounds phytoestrogens, specifically isoflavones. This research analyzed Mississippi-grown kudzu roots, leaves, and flowers for antioxidant activity and total phenolic content and evaluated consumer acceptability of food products containing kudzu. Results indicated kudzu flowers, roots, and leaves contained phenolic compounds and the antioxidant activity amounts in flowers, roots, and leaves were 77.9%, 75.7%, and 56.5%, respectively. The dip products that were developed and evaluated were mayonnaise- and sour cream-based dips that contained either dried kudzu leaves or dried spinach and other seasonings. Healthier versions of dip products were developed using light mayonnaise and light sour cream and omitting salt. Consumer sensory panels evaluated appearance, aroma, flavor, texture, and overall acceptability of the dip samples using a 9-point hedonic scale. A randomized complete block design with three replications was used to determine if differences (p<0.05) in consumer acceptability existed among treatments. On average, the regular spinach dip was moderately liked and preferred (p<0.05) over the other dips. The regular kudzu dip was moderately liked and preferred (p<0.05) over the healthier kudzu and spinach dips. Cluster analysis partitioned consumers into five groups based on preference and acceptability of vegetable dips. Results indicated 39% of panelists rated the dips at like very much and did not differ (p>0.05) in their liking of dips, 42% preferred (p<0.05) the regular spinach dip and 50% liked all vegetable dips. A kudzu blossom jelly product was developed using kudzu flower liquid, sugar, pectin, and lemon juice. Consumer sensory panels evaluated the prepared jelly product, a purchased kudzu jelly, and a purchased scuppernong jelly. A randomized complete block design with three replications was used to determine if differences (p<0.05) in consumer acceptability existed among jellies. The purchased kudzu jelly was preferred (p<0.05) for overall acceptability (like moderately) compared to the prepared kudzu and scuppernong jelly, which were rated similarly between like slightly and like moderately.

The impact of norms on suboptimal food consumption : a solution for food waste

Stangherlin, Isadora do Carmo January 2018 (has links)
The main goal of this study is to investigate stimulus that can be used to increase consumers purchase intentions toward suboptimal food products. Consumers seem to have low preferences to buy fruits and vegetables with unusual appearance, products with damaged package and close to the expiration date, usually called suboptimal food products. However, rejection of suboptimal food is an important contributor to food waste levels. Interventions aimed at encouraging the purchase of suboptimal food are scarce, however needed. This study used the theory of normative influence to test the effect of both descriptive and injunctive norms on a product with an unusual appearance, a product with a reduced expiration date and a product with a damaged package. The first study tested different messages appeals to create a realistic norm in study 2. From this study, it was selected the social message appeal and the frequencies of purchase toward each product, using them in the messages as the prevalent norm The second study analysed the effect of injunctive and descriptive norms of purchase intentions toward suboptimal food and also tested the effect of environmental concern and food waste problem awareness. Results show that both environmental concern and food waste problem awareness impact purchase intentions toward suboptimal food. Additionally, appeals employing social norms proved to affect purchases intentions toward these products. However, this effect only occurred for the vegetable with an unusual appearance and the product with a package damaged. For the product with a reduced expiration date the norms had no effect. Moreover, for the product with an unusual appearance, food waste problem awareness mediated the effect of injunctive norm on purchase intentions. Based on the results, this study contributes to the theory of normative influences by showing that, in a general way, this theory is applied to food waste reduction issues, more specifically, with suboptimal food consumption. However, it is necessary to consider the type of sub-optimally and the context where the influence is applied. Additionally, was discussed how social norms can be used to tackle food waste and the implications for marketing and policy actions.

Brand management vybrané značky / Brand management of selected brand

Honzíková, Dana January 2010 (has links)
This thesis addresses the subject of brand management. My main objective was to summarize the issue of brand management and apply the acquired knowledge on the selected brand of food products on the Czech market, i.e. to assess its current management and the current situation and where appropriate, propose recommendations for the future. I use the case study method, the method of survey and analysis of primary and secondary data. The theoretical part deals with the concept of brand, its features and basic identifiers. Furthermore, I analyze the theme of brand management and brand value (equity) and focus on individual steps of brand management scheme by S. M. Davis. The practical part describes the market, the manufacturer of the brand and the brand itself. Elaborated is also a questionnaire survey conducted under the thesis. The final part is devoted to summary and analysis of the current situation of brand management and design of possible improvement in the future. The results of this thesis could be used as incentive for brand management of the brand, or for inspiration for the management of other food brands.

Quantifying the global cropland footprint of the European Union's non-food bioeconomy

Bruckner, Martin, Häyhä, Tiina, Giljum, Stefan, Maus, Victor, Fischer, Günther, Tramberend, Sylvia, Boerner, Jan 18 February 2019 (has links) (PDF)
A rapidly growing share of global agricultural areas is devoted to the production of biomass for non-food purposes. The expanding non-food bioeconomy can have far-reaching social and ecological implications; yet, the non-food sector has attained little attention in land footprint studies. This paper provides the first assessment of the global cropland footprint of non-food products of the European Union (EU), a globally important region regarding its expanding bio-based economy. We apply a novel hybrid land flow accounting model, combining the biophysical trade model LANDFLOW with the multi-regional input-output model EXIOBASE. The developed hybrid approach improves the level of product and country detail, while comprehensively covering all global supply chains from agricultural production to final consumption, including highly-processed products, such as many non-food products. The results highlight the EU's role as a major processing and the biggest consuming region of cropland-based non-food products while at the same time relying heavily on imports. Two thirds of the cropland required to satisfy the EU's non-food biomass consumption are located in other world regions, particularly in China, the US and Indonesia, giving rise to potential impacts on distant ecosystems. With almost 39% in 2010, oilseeds used to produce for example biofuels, detergents and polymers represented the dominant share of the EU's non-food cropland demand. Traditional non-food biomass uses, such as fibre crops for textiles and animal hides and skins for leather products, also contributed notably (22%). Our findings suggest that if the EU Bioeconomy Strategy is to support global sustainable development, a detailed monitoring of land use displacement and spillover effects is decisive for targeted and effective EU policy making.

The Impact of Cartoon Characters and Front-of-Package (FOP) Nutrition Information on Parental Perceptions of Children’s Food Products

Sae Yang, Wiworn January 2012 (has links)
Childhood obesity is a major public health issue. Canada has one of the highest childhood obesity rates in the world. Food advertising and marketing have contributed to the rapid rise in childhood obesity. High energy and low nutrient foods have been promoted directly to children through attractive imagery on packages, including the use of popular cartoon characters. Children’s food packaging also features a range of nutrition information targeted at parents, including nutrition claims; however, there is relatively little research on the impact of these nutrition claims and the extent to which they may interact with child-friendly imagery to influence parents’ perception of food quality. The current study used a 2 x 2 experimental design to examine the effect of four front-of-package (FOP) nutrition information and four cartoon characters on parental perceptions of children’s food products. Participants consisted of 897 parents recruited across Canada through GMI, a market research company. Participants were over 18, had at least one child between ages 4-10 and the primary shopper of their household. Participants completed an online survey in July 2011. Participants were shown images of food products with or without cartoon characters and with or without FOP nutrition information and were asked to rate the food product on appeal, nutritional quality, intention to buy and willingness to pay. Participants were also asked to rate the FOP nutrition information on believability, ease of understanding and perceived effectiveness. Linear mixed modelling examined the influence of cartoon characters, FOP nutrition information and socio-demographic factors on these outcomes. Results indicated that cartoon characters increased product appeal and FOP nutrition information increased the perceived nutritional quality of food products with low nutritional value. No significant differences were observed for intention to buy or willingness to pay. There was no consistent pattern between socio-demographic factors and product rating outcomes. For FOP nutrition information ratings, Health Check and Source of Fibre were rated more believable, easier to understand and more effective overall than Sensible Solution and Given the Thumbs Up by Kids. Overall, the findings indicate that cartoon characters can increase the perceived appeal and FOP nutrition information can increase the perceived nutritional quality of food products with low nutritional value.

There was done the analysis of the literature’s data on the mode, how heavy metals and radionuclides get into the organism and affect the human health. The legal regulation of the heavy metals and radionuclides in the LR and EU was discussed together with the monitoring data found in the literature on the heavy metals and radionuclides. The information and research material (data on the amount of undesirable remains, including heavy metals and radionuclides) were received from the National Laboratory of Veterinary. Their statistical analysis was done with the help of SPSS statistical package (SPSS Inc, 1995-2007). According to the data analysis, the biggest amounts of lead were found in 1998 (researches were done in 1998-2004). In some samples (fowl, fish) the lead’s norm was exceeded from 2 to 5 times. The biggest amount of lead was encountered in milk samples in 1998. Among 13 analyzed samples, 11 had the lead’s norm exceeded 10 times (0,11 – 0,2 mg/kg) when the norm is 0,02 mg/kg. In 1998 a lot of lead was found in game; the norm was exceeded in all 39 samples, but in ten of them there was extremely... [to full text]
