Establishment and evaluation of a Barley starch isolation method with focus on representability

The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.

Long-term Storage of Starch Potato and its Effect on Starch Yield

Lyckeby Starch AB is a farmer-owned company that produces products based on potato starch. In order to increase their production efficiency and their international competitiveness the company is investigating the possibilities of keeping their factories open longer. To achieve this, potato has to be stored for a longer period of time than what is practiced today. Starch potato is usually stored in large piles covered by straw and plastic, either in the field or on the farmyard. The objective was to examine in what way starch yield (starch content*tuber weight) in three different potato varieties was affected by storage in two different types of storage piles. The potato was stored for three months in total and starch content and tuber weight were controlled throughout the period. Stored tubers were also visually examined and prescense of mechanical damage as well as wet rots and dry rots was recorded. Bacteria and fungi were isolated and identified. In general, varietal differences were greater than differences between the storage piles.

Service recovery i praktiken : En kvalitativ studie av användandet av service recovery-teorier i ett tjänsteföretag

Denna studie har undersökt den praktiska användbarheten av befintliga teoretiska ramverk inom service recovery-området som utgångspunkt för att utvärdera och utveckla recovery-arbetet i tjänsteföretag. En datainsamling på ett större svenskt tjänsteföretag har genomförts med ett fokus baserat på befintliga teorier om service recovery. Det insamlade materialet har sedan bearbetats av nyckelpersoner på företaget och funnits leda till en inte oansenlig mängd insikter och åtgärdsförslag relaterat till organisationens recovery-verksamhet. Detta leder till slutsatsen att de teoretiska ramverk som beskriver service recovery-processen framgångsrikt kan användas för att styra utvärdering och utveckling av en organisations recovery-verksamhet. Information som insamlats med befintliga teorier som lins har visats vara relevant för en organisations insikter om det egna recovery-arbetet samt bidragit till utveckling av recovery-verksamheten..

"Klyschor som funkar" Göra rätt saker eller göra saker rätt : En studie om service recovery i hotellbranschen

Every business is subject to service failures. The process of correcting these failures and turning disappointed customers back into happy ones is called service recovery. This is particularly important in the hotel business, where there are many moments of truth where customers may become dissatisfied. To further complicate things, service recovery is a process where you may have to correct errors of others - people beyond your control. The research field is relatively new and there are no turn-key solutions as to how to systematically work with service recovery.

Stärkelsers funktion som konsistensgivare vid olika temperaturer i pulversoppa : en experimentell kvantitativ studie

More often consumers demand instant dry soup that can be prepared with a water temperature below 100o C, which is currently not possible, because the dry soup becomes too thin when using water with a lower temperature. In this study, various kinds of starch studies were made to optimize the starch used in the existing product to make it more viscous at both high and low temperatures. The result was that one of the two starches present in the existing product was retained by change in quantity as it contributed to important flavor parameters. The second was removed and replaced with a starch that made the product more viscous at lower temperatures. To find out if the new product differed from the existing product a viscosity measurement and a sensory paired preference test were made.

Cassava as an additive in biomass fuel pellet production :

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

Lönsam produktion av stärkelsepotatis : timing och skördeanpassade åtgärder

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Återhämtning från alkohol och drogproblem : - en fenomenologisk studie av fyra människors återhämtningsprocesser

The aim of this study is to increase understanding about addiction recovery. More specifically, we want to know what people who have had problems with alcohol and/or other drugs perceive as helpful and important for their recovery process and how we can understand this process.The study was conducted by means of qualitative semi-structured interviews with four people who have had alcohol and/or other drug problems. The analysis is based on a transtheoretical model of change from addictive behaviours, coping, interactionist theories and also a recovery perspective, inspired by research on recovery from mental illness . Main findings are that recovery from addiction can be understood as an individual process that takes place in a social context and can follow expected phases, although there are large individual differences in the process. Through the recovery process it has been of importance to the participants in the study to redefine themselves and their problems, get support from others, find ways to cope with their problems, get involved in meaningful activities and to expand their social roles.

Barley starch, structure and properties

Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.

Service Recovery : Tjänsteföretagens viktigaste tillgång i kvalitetsutvecklingen?

Uppsatsen skrevs i samband med Konsumentverket och undersöker hurKarlstadsbuss använder sig av service recovery i sitt dagliga arbete.Service recovery innebär att så fort en kund upplevt något negativt i samband med ett företagsmöte så ska denne få återkoppling i form av en ursäkt, pengar tillbaka eller någon annan typ av förmån. Lyckas företaget ge kunden detta så fort som möjligt så förhindrar det att kunden får en negativ bild av företaget som den sprider vidare till personer i sin omgivning.För att få djupare kunskap i ämnet har tidigare teorier om klagomålshantering, service recovery och hur företag kan motivera sina anställda till att vara mer serviceinriktade studerats.Syftet med den här uppsatsen är att studera hur service recovery används i ett kollektivtrafikföretag och hur det tillämpas i hela organisationen.Först studerades teorier inom ämnet och sedan gjordes en empirisk undersökning, uppsatsen är med andra ord uppbyggd enligt den deduktiva strategin..

Framtagning av ett nytt recept för clear-coat batter av pommes frites : En teknisk och sensorisk utvärdering

The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.

Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

Kognitiv återhämtning efter generell anestesi

ABSTRACTBackground: After general anesthesia the cognitive ability is temporarily impaired. Cognitive recovery is necessary for the patient to be able to assimilate the information that she / he gets postoperatively. It also increases the patient safety. There are few methods to estimate and assess the patient's cognitive recovery before and after anesthesia. The purpose of this study is to test the usefulness of the instrument PQRS and to assess the patients cognitive recovery after anesthesia.

Personalens bedömning av tillämpningen av ett återhämtningsperspektiv inom vården

AbstractThe purpose was to investigate whether a recovery perspective, viewed from a psychosocial approach is applied in municipal / private and county related care and rehabilitation. A recovery perspective means that the attending staff ensures that the clients are viewed as holistic individuals, where all aspects of life are considered to ensure adequate care and rehabilitation. A questionnaire was answered by staff in psychiatry, social psychiatry and addiction treatment from different areas of the municipal / private and county related sector.The results show no difference in application of a recovery perspective between these two types of organizations. However, there is a slight tendency (non-significant) to lower-rated general individual competencies for municipal / private. There is also a strong tendency (non-significant) to a general difference between the aspects of the implemented recovery perspective, where the tendency is that the respondents as a whole estimate that the organization to a greater degree creates good conditions for a recovery perspective compared to the degree they are actually working on that basis.
