Abstract

Monitoring of the mechanical properties of fruit obtained from cucumber plants is extremely important because of their use in processing, since these properties are reflected by the finished products of processing. Mechanical defects produced at the time of harvesting, during transport and at the specific stages of processing may adversely affect the course of technological processing (brine and vinegar pickling), resulting in spoilt preserves no longer useful for commercial purposes. The study was designed to identify selected mechanical properties in fresh and pickled fruit obtained from field cucumbers during spontaneous fermentation and fermentation promoted by selected lactic bacteria cultures. Additionally, water contents were measured in fresh cucumbers. The findings show significant differences between the analysed parameters.

Abstract

The study has identified selected mechanical properties of fresh and stored fruit of large cranberry. The analyses focused on the changes in the values of peel and flesh puncture strength in the selected cranberry varieties depending on water content and storage duration. Measurements were also performed to examine deformations and energy needed to cut through the fruit peel and flesh. The value of breaking stress was calculated. The findings show a decrease in the relevant parameters during storage of fruit obtained from the examined varieties of large cranberry. Mean water contents in the fruit of the relevant varieties were in the range of 86.4-89.1%. There was a notable decrease in the mean value of peel and flesh puncture strength in the fruit of the relevant varieties of large cranberry. The mean value of peel and flesh puncture strength in the fresh fruit of cranberry was 6.1 N, and after 40 days in storage the value decreased by 2.3 N.

Abstract

The paper is designed to present a method to estimate greenhouse gases (GHG) uptake or emissions in the absence of data for peat bog areas (GEST method). The paper presents the research results produced by a project on “Limiting CO2 emissions via the renaturalisation of peat bogs on the Eastern and Central European Plain”. The study area consisted of three peat bogs: Kluki, Ciemińskie Błota, and Wielkie Bagno (Słowiński National Park). The GEST method relies on the estimation of gas emissions on the basis of vegetation and water levels and greenhouse gas coefficients for each given habitat type provided in the research literature. The greenhouse gas balance was calculated for a baseline scenario assuming the lack of human impact and for a scenario taking into account human impact in the form of peat bog preservation. Initial research results indicate that there is a total of 41 GESTs in the studied bog areas and that a reduction in CO2 emissions of approximately 12% will occur following what is known as renaturalisation by raising the groundwater level, felling of trees across the bog, and making changes in habitats.
