Background. The development of food ingredients that beneficially affect the human organism has attracted much interest recently. Especially important seems to be resistant starch i.e. starch fraction which resists hydrolysis catalysed by amylases present in the gut. Although research on starches resistant to amylolytic enzymes began in 1990s, there is still lack of cheap and easy methods of its production. The aim of the work was to optimize the process of high pressure homogenization of potato starch pastes in order to reduce their digestibility to the utmost. Material and methods. The optimization of the homogenization process was examined by means of the commercial software STATISTICA. Homogenisation was performed for the pastes of the concentration of 5%. Digestibility of the obtained starch samples was evaluated by the amount of glucose formed after 16 h of hydrolysis with the mixture of pancreatic alpha-amylase and glucoamylase. Results. It was found that high pressure homogenization of starch pastes provides products of digestibility reduced up to 50%. Moreover, it was proved that at low temperatures, it is necessary to apply high pressure and low number of passages. At high temperatures, it is necessary to apply low pressure and high number of passages. Medium values of all of parameters did not provide low values of digestibility. Conclusions. The application of the response surface methodology (RSM) for development of dietary starch products allows a quick identification of important process factors (such as temperature, pressure or numbers of passages) and shows interactions between them

Over the last five decades the Toyota Production System (TPS) has evolved from an advanced socio-technical concept in manufacturing to a participative design for large-scale change management. Toyota has been able to sustain a strategic competitive advantage by applying TPS as a process innovation and intervention, as measured by quality, reliability, productivity, cost reduction, sales and market share growth, and market capitalization. Many automotive companies are trying to replicate Toyota's success with TPS in their respective business. But is it possible to effectively implement the TPS in non-automotive industry? This paper includes basic theoretical information about TPS and subsequently the application of this system in non-automotive industry.

The new capital system shaping Polish economical reality has made entrepreneurs aware of the necessity to custom-orientate their activities. Due to strong competition, recognition of customers’ preferences is essential for the success of all enterprises. On the other hand, the awareness that, for increasing numbers of customers, not only product quality and price but, equally or even more importantly, servicing standards are beginning to gain in importance causes that manufactures are beginning to pay more and more attention to issues associated with logistics. Such problems are particularly important for companies producing prefabricated wooden houses as the undertaking of house construction is a multi-stage process and requires a long-term contact with the client which does not end with the moment of house purchase but continues long after moving in. This article aims at presenting the flow of raw materials, materials, semi-finished products and finished articles in an enterprise manufacturing prefabricated wooden houses and at indicating problems that may occur at individual phases of the process.

Requirements for flexible manufacturing have been increasing in the last years. In order to insure effective operation of expansive manufacturing equipment, which has to run automatically and unattended, tool monitoring is important. Therefore, the essential problem to be overcome to achieve the full potential of unmanned machining is the development of effective and reliably sensors systems to monitoring the process and corrective action in case abnormal operation. The ultimate goal of the development of such production equipment is to enhance the overall economic of the manufacturing process. Even when there are at present many monitoring systems commercially available in the market for tuming processes, serious difficulties still remain to be solved to apply monitoring systems successfully in machining centers. Being these difficulties mainly related with the limited accessibility to the rotating tool for sensing purposes in tool driven machining processes. Therefore, the primary objective of this paper assess the feasibility of using force signal analysis as means for monitoring tool condition in drilling.

In the first part of the paper there is presented logistic and specially informational infrustucture based on the megatrendes influenced on the Eurpean Market. To rebuild traditional supply chains management are presented two main strategies, based on M. Porter’s: leader cost and heterogenity strategies applied to information technology environment. First of them is Transparency Strategy that improve chain effectiveness. The second one is Flexibility Strategy based on outsourcing techniques that gives possibility ”to meet the needs of the present without compromising the ability of future generations to meet their own needs”. The Transparency Strategy is the main strategy and Flexibility Strategy is secondary strategy. To cover future needs it’s necessary to reach higher quality and security of products and services To reach them there are proposed 3 substrategies: Compiance Strategy, Substrategy Oriented at Improroving Processes and Market-Oriented Substrategy. To fulfil upper strategies the following outsourcing strategies can be applied: Lean, Agility and Leagility Strategies. To choose one of them its depends on sphere of logistic activities that can be outsource. To overcome this constraints in the last part of the paper there are presented the principles of the platform Food for Life, which will be build for all it’s future users and stakeholders.

The product realization process, which consists of product planning, design, process planning, and manufacturing. The development time is an important factor. Accelerated development of the product results in a longer sales life, a marketplace advantage by gaining early customers, a pricing advantage for the company, and the ability to use more up-to-date technology in the product. An increase in development time has a much greater effect on profits than, an increase in production costs or development costs. The decision regarding accelerated product development must consider the trade-off among the parameters of interest as are product features, product cost, development speed, and development expense. Often, the development of a product is delayed in the early stages because, no one in the company realizes its importance. Another factor that can cause delays is when a company tries to develop an entirely new product, often using new technology- There is less risk if a product is improved in stages, using only tried and tested technology. The chief factors that facilitate faster development of products are better communication between departments, which also leads to lower cost and higher quality products. The company increases its market share and enjoys higher profits by the early introduction of a product.
