One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in Fruit juices. The interfering substance that is present in the highest amount in most Fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three Fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

Brämhults Juice AB is one of Sweden?s leading producers of fresh Fruit juices and drinks. The fruit drinks last 3 days once opened and when stored in a refrigerator kept at 7°C. Since factors that shorten the drinks? best before date are usually not noticed until the entire batch has expired, it would be advantageous to find a way to accelerate the drinks? natural deterioration, so that an unusal short best before date is noticed before more products are shipped off to the stores.

The purpose of the project was to exam steams ability to sterilize carrots infected withLactobacillus plantarum. The project was a cowork with Brämhults Juice AB. They hadobserved an increase of Lactobacillus in the production of carrot juice during the summer. Tokeep the flavour of fresh fruits, the juice is treated carefully with heat. This means that thejuice only stays fresh for a few days, around two weeks for an unopened package and threedays for an opened package.In an attempt to remove the remaining Lactobacillus of the carrots, steam is tested as an extrastep in the production of juice.

Out of totally 1862 hectares of the Swedish fruitacerage, only 142 hectares are cultivated according to the EU-standards for organic farming. Only 73 hectares are connected to the Swedish control organisation KRAV. Therefore only fruit from this acreage can be sold as organic. The aim of the study was to further investigate the organic fruit production regarding cultivation, market and firm strategy. Through interviews with 36 fruitproducers the situation for organic fruit and the companies were examined.

The interest for locally produced food is increasing due to consumer concern about the environment, distrust of industrial foods and a demand for high quality products. Apple is the predominant fruit crop in Sweden, and by processing apples into cider and vinegar, these products could significantly contribute to the development of the market of local foods.In this study different yeast types and different bacterial cultures were evaluated for their suitability in cider and vinegar production from cloudy apple juice. Ten apple cultivars (Aroma, Baldwin, Belle de Boskoop, Bramley, Cortland, Gravensteiner, Ingrid-Marie, Jonathan, Rubinola and Spartan) were also evaluated for their suitability for production of juice, cider and vinegar. Chemical analyses including total soluble solids, titratable acidity and total phenols were performed on the products along with sensorial evaluation by taste panels.The yeast strains were shown to have an effect on fermentation rate and the resulting content of total phenols in ciders fermented from cloudy apple juice. Dry commercial starter strains gave a higher appreciated cider compared to cider that was spontaneously fermented, and the ale yeast Safale S-04 was concluded to be the most suited for fermentation of cloudy apple juice.For vinegar production, the bacterial culture had an effect on TSS, but not on any other chemical or taste characteristics.

The consumer often chooses the store depending on the quality of the fruit and vegetable department. A study has proven that about half of the purchases in this department are impulsive. This gives the store a good possibility to influence the consumer?s behaviour in the fruit and vegetables department. Compared to other products, like pasta or rice, there are few brands represented in the f & v-department.

The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality. The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

Food insecurity is a great problem worldwide and Ethiopia is one of the sub-saharan countries that are suffering from poverty and food insecurity and a large part of the population are living in a state of undernourishment. To reduce these problems, a successful horticulture production can be an important factor. Compared to other crops, fruit production in Ethiopia has not been a large part of the agricultural sector. However, the demand on the domestic market is increasing as well as the production for avocado and mango. To increase food security it is important to focus on ways to decrease post-harvest losses of food products and not only have the productivity of agriculture in focus.

The purpose of this study is to examine the change in consumer behaviour regarding the intention towards buying fruit when the layout of the fruit section has been altered. We want to increase the probability of making impulse purchases by altering the layout. In our study we have combined structured quantitative observations with structured quantitative as well as qualitative interviews, with secondary data in the form of sales data from two selected ICA-stores. We chose to use this triangulated approach in order to cross-examine our findings and overcome the limitations of one method by the use of another. Further, the Latin square design was used for the observations as a means to acknowledge the calendar effect during the experiment.

The purpose of this study was to evaluate which apple cultivars are best suited for production of juice and cider. The study was limited to 41 cultivars. Common as well as uncommon apple cultivars were selected from available cultivars in the cold storage at Balsgård, Department of Horticultural Plant Breeding and Biotechnology, SLU.The practical part of the study consisted of the apples being pressed, and then the juice characteristics being assessed by appropriate criteria and methods of analysis. The analyses consisted of measurment of soluble sugars with a refractometer (Brix), titration of total acidity, determination of total phenolic content with a spectrophotometer, estimation of alcohol content by density meters and qualitative taste tests.The study did not account for different maturity of cultivars. Different apple cultivars were pressed on separate occasions, before and after Christmas 2010.

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

To identify and evaluate apple cultivars is not an easy task, since the taste and appearances of the fruit are affected by where the apple tree grows. At the Balsgård new apple gene bank there is a unique and interesting collection of over 260 different cultivars from all over the world. To find out if these cultivars are consistent with previously published descriptions, the fruit was evaluated for some of the cultivars. Among the evaluated cultivars some were selected that could be suitable for cultivation and/or fruit breeding. A few cultivars were in addition analyzed at a consumer evaluation at the Kivik apple market where visitors could vote for the most beautiful apple and the best taste.

Gene technology has become more and more attractive in plant breeding during the last twenty years. This is probably because it can readily improve the existing commercial cultivars that have only one or a few drawbacks by modifying one or a few genes without changing the main genetic constitution. In this regard, gene technology is more effective than conventional breeding.The aim of this project was to analyze the fruit quality of the non-transgenic apple scion ?Jonagold? grafted on non-transgenic and rolB-transgenic apple rootstocks. The rootstocks used were M9-rolB1, M9-rolB2, M26-rolB and non-transgenic controls M9 and M26.
