A “superfood” should have a high content of bioactive substances with a positive impact on human health. Seven different cultivars of goji berry fruits (Lycium chinense Mill.) grown in north-western Poland were evaluated for its physicochemical parameters, antidiabetic and antioxidant activity, and polyphenol content. The length of 1-year-old shoots ranged from 36 cm (‘Big Lifeberry’) to 82 cm (‘Korean Big’). Cultivars from the group of Big were characterized by the biggest fruits (17.3-24.2 mm) with the greatest weight of 100 fruits (96.7122.1 g). ‘Big Lifeberry’ contained high amounts of L-ascorbic acid (408 mg 1000/g) and provitamin A (190 mg 1000/g) and showed high antidiabetic (α-amylase IC50=33.4 mg/mL; α-glucosidase IC50=9.9 mg/mL) and antioxidant activity (ABTS·+ 6.21 and FRAP 5.58 mmol T/100 g). ‘Big Lifeberry’ was also characterized by a high total content of polyphenols (43.64 mg 100/g). Furthermore, the nitrite content in all the cultivars tested was at a relatively low level. Among the examined cultivars, the most attractive one concerning the consumers’ point of view of the size, weight and high content of health-promoting compounds is ‘Big Lifeberry’.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.

The metal content was determined using the ICP-OES method with prior microwave mineralization of the soil, plant (goldenrod, dandelion, rapeseed, tilia and fir), bee bodies and honey samples collected from 10 sampling points (U-5 and E-5). The impact of soil pH on heavy metal mobility was also evaluated. It was found that Podkarpackie soils are less contaminated with heavy metals as compared to other regions of Poland and only in the case of cadmium an enhancement of the natural background level was observed. The migration of heavy metals, especially cadmium, in the soil-plant-bee-honey food chain was accelerated by soil acidity (p<0.05). The influence of human activity (region development) on heavy metals concentrations was not significant (p>0.05). Based on bioaccumulation factors, goldenrod and dandelion plants were confirmed as cadmium accumulators. It was also confirmed that the bodies of bees act as an effective barrier to the migration of heavy metals from the environment to honey, due to this, honey is free from these metals and safe for human consumption.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.

Native to Indo-Chinese region, it is considered to be an ‘under-utilized’ or ‘orphan’ crop. Rice bean is known to possess high nutritional potential and antioxidant activity. But the use of rice bean supplementation in routine diet is limited despite its high nutritional profile due to the presence of non-nutritional factors. Thus, various pre-treatments like soaking, germination, oven roasting, sand roasting, boiling and pressure cooking at different time and temperature were carried out to reduce the anti-nutritional content of rice bean and to study its effect on antioxidant activity and phytochemical content. All the pre-treatments were able to significantly reduce the anti-nutrient content in rice bean, but germination showed the maximum reduction. Also germinated rice bean showed the maximum antioxidant potential and maximum content of total phenols, total flavonoids, vitamin C and carotenoids. Rice bean has been underutilized so far, owing to its antinutrient content and low popularity. This experiment attempted to use low cost processing to reduce the content of antinutrients and track the antioxidant content in rice bean. The concluded processing could be adopted for commercial applications for dietary supplementation.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.

However, there is a problem with the handling of fruit that does not meet the requirements for dessert berries. One of the methods to use the fruit is drying. The research was conducted in the Department of Horticulture at the West Pomeranian University of Technology in Szczecin. The fruit was harvested at a plantation specialising in the production of highbush blueberry from irrigated and non-irrigated plots. This study aimed to assess how cutting or pricking highbush blueberry fruit affects the duration of the sublimation drying process – freeze-drying. The biological value of fresh, freeze-dried, and rehydrated fruit was assessed. The amount of fruit left on bushes depended on the weather prevailing in the growing season, especially during the harvest period. The mass of fruit left on the bushes was approx. 1 to 2 t/ha. Although these fruits were small, they had a very high biological value. After freeze-drying and rehydration, the blueberry fruit retained their colour, high content of polyphenols and showed high antidiabetic activity and antioxidant capacity. The large fruit reached the moisture content of approx. 12%, which ensures safe storage and the appropriate texture, after 46 hours of drying, and the smaller fruit - after 32 hours. Fruit cutting or pricking reduced the drying time by half. Reducing this time decreased drying costs and increased biological value.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.

A lot of bioactive contents are characteristic for them. Holoparasites of the family Orobanchaceae are known to be an important and rich source of polyphenols, especially metabolites of the phenylethanoid glycosides (PhGs) group. However, only a minority of the species in this family have been phytochemically tested. They are reported to have multiple biological and therapeutic effects and have been used for centuries in traditional Chinese medicine. This is the first study to present phytochemical profiling for a representative of genus Phelypaea. The chemical composition and biological activity in particular organs of the parasite, P. tournefortii, were determined. The interaction with its host, Tanacetum polycephalum (Asteraceae), from different places and altitudes was also studied. We presented the determination of polyphenolic compounds with the UPLC-PDA-MS/MS method, antioxidative effects and inhibitory activities, polyphenols, and nitrates content, ABTS•+, DPPH, FRAP, as well as colour parameters. The polyphenols profile of the parasite and host were different in quality and quantity. Identification of polyphenolic compounds revealed 41 compounds, 15 in the parasite (12 phenylethanoids and 3 anthocyanins), and 26 in the host (mainly flavonoids and phenolic acids). The amount and biological activity of polyphenolic compounds present in Phelypaea was very diverse and depended on the host plant and the parasite’s organs, as well as on population altitude. The results show that P. tournefortii is a potential source of functional and pro-health components. They also direct researchers’ attention to the parasite’s organs, host, and environmental influence.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.

Malt analyses were carried out in accordance with the ECB Methods. The wheat malts were found with lower Kolbach index, and high viscosity was identified in wort obtained from wheat. The findings related to the wheat malts showed better quality parameters in Elixer variety compared to Rockefeller variety. Elixer wheat malt had higher diastatic power (427.03 WK) and lower extractivity (81.85%) compared to Joy barley malt (376.12 WK and 85.79%). Laboratory tests assessing the malts and wort showed that winter barley grain has high malting quality and can be used without modifications in the malting and mashing processes in brewing industry. It is necessary to conduct further research focusing on cultivation, agricultural techniques and technologies applied in wheat farming, in order to obtain cultivars which can be used to produce high quality malts.","PeriodicalId":377090,"journal":{"name":"Acta Universitatis Cibiniensis.
