Summary A rum pot (Rumtopf) preserves the immersed fruits by alcohol and sugar. The components of the immersion medium rum/sugar (especially alcohol and sugar) are mixing rapidly with the components of the immersed fruits (especially water and red plant dyes). To prevent an unwanted fermentation, it is recommended to use rum with high alcohol content. [ABSTRACT FROM AUTHOR]

The aim of the present study was to determine macro- and micro-elements of fruits commonly available on the Czech market and estimate their daily reference intake. The locally produced Czech fruits (grape wine, apples, pears, plums and peaches) and exotic fruits (physalis, kiwifruit, fig and avocado) were analysed. The determination of mineral elements was carried out with the validated Atomic Absorption Spectrometry method. Statistically significant influence (p < 0.001) of fruit's geographical origin on the content of almost all analysed macro- and micro-elements (Mg, Ca, Mn, Zn, K and Cu) and Na in fruits (p < 0.05), except Fe was confirmed. In many cases, locally produced Czech fruits contained lower levels of macro- and micro-elements in comparison to exotic fruits. Potassium and iron were the most abundant macro- and micro-elements found in the analysed fruit samples. The highest average percentages of daily reference intake (DRI) and adequate intake (AI) for an adult were obtained for exotic fruit samples: physalis, avocado and fig. Factorial analysis allowed the discrimination between the locally produced Czech fruit samples and the exotic fruit samples and can be used for the differentiation with respect to their origin.

Sour cherry (Prunus cerasus L.), is a fruit species of Prunus in the subgenus cerasus in Rosaceae (Rosaceae) family. It is closely related to the sweet cherry, but it has a more acidic fruit. Two major cherry tree varieties are grown in Turkey. One of them is 'Kutahya' cherry which suitable for use with all types of fruit and the other one is 'Hungarian Cherry' cultivation has spread to all regions of Turkey, although commercial aquaculture has been limited areas which are suitable climatic conditions. In Turkey, the most labor force is in harvesting was determined in sour cherry studies concerning the production process. In addition, the sour cherry harvesting constitutes of 30–60% of total production costs. Harvesting process is emerged as the most important factor determining in the cost of production. Therefore, basic research has to be made for cherries and system use in mechanical harvesting operation. In this study, some physico-mechanical properties were determined for mechanical harvesting of two cherries ('Kutahya' and 'Hungarian Cherry') in four different harvesting times. These properties are such as dimensions, projection area, fruit hardness, picking force of fruit stalk, picking force of fruit from stalk. To determine these parameters, an apparatus consisting of a load cell, and slot was used. The knowledge on these parameters is important for the development of new technological equipment and for reducing the losses occurred in sour cherry production. [ABSTRACT FROM AUTHOR]
