Opis:
The aim of the study was to evaluate the influence of type of the solvent (water, aqueous ethanol and ethanol) on the antioxidant properties of four various herbs: couch grass (A. repens), milk thistle (S. marianum), dandelion (T. officinale) and fireweed (E. angustifolium) measurement by three common UV-VIS methods (TPC, ABTS+, DPPH). The results were collected through the Vision-Pro™ UV-VIS spectrophotometer software. Aqueous ethanol was the most effective solvent for extraction for all type of herbs. Fireweed contains the highest amount of polyphenol compounds (0.625 μg GA/ml). The lowest antioxidant capacity was presented by extracts from couch grass (0.019 μg GA/ml).

Opis:
The aim of the study was to evaluate the effect of acid whey as a starter culture on selected physicochemical properties of fermented pork sausage after ripening (21 days). Four variants of the product have been produced. The first variant (PKS) - cured sausage (2.8%) with starter cultures. Second variant (SSK) – salted sausage (2.8%) with acid whey (5%). Third variant (SKS) – salted sausage (2.8%) with starter cultures. In the fourth variant (PSK), sea salt (2.8%) and acid whey (5%) were used. The research included determination of pH value, water activity, TBARS indicator, analysis of total content of haem pigments and heme iron, determination of color parameters by CIE L * a * b * system and analysis of sausage texture parameters (TPA). The pH values of sausages with acid whey were significantly lower compared to fermented sausages with starter cultures. The highest TBARS index was observed in the SSK (0.612 mg MDA / kg), and the lowest in the PKS sample (0.118 mg MDA / kg). The highest overall content of heme dyes and heme iron was recorded in the PSK test. A higher share of redness was observed in the general tone of color in cured sausages (PKS, PSK) by about 1-2 units compared to salted samples (SSK, SKS). In case of texture, significantly higher values of the hardness parameter were observed in the PSK test as compared to the remaining test samples. Based on the tests, it has been found that it is possible to use acid whey as a starter culture in fermented pork sausage. However, the best results were obtained in the curing sample with acid whey (PSK).

Opis:
The aim of the study was to evaluate the influence of lyophilized plant extract on color of canned meat with reduced amount of sodium (III) nitrite measured by spectrophotometric methods. The results were collected through the X-RiteColor® Master software. The results of the experiment show that reduc-tion of nitrite salt is possible but additional fortification is required: the best results were obtained when the extract was added in the amount of 0.015%.
