Morphometric Characterization and Body Measurement Correlation in Dubska Pramenka Sheep

Summary

The purpose of this study is to determine the morphometric characterization of Dubska Pramenka sheep and to establish a relationship between the most important body measurements of ewes and rams within the strain. The Dubska Pramenka is one of the biggest strains within the Pramenka breed. The wither heights of ewes and rams were 73.37 cm and 79.92 cm respectively, whereas the body lengths were 74.66 cm (ewes) and 80.42 cm (rams), and the rump heights were 73.72 cm (female) and 80.16 cm (male). Based on the data presented, it is evident that the Dubska Pramenka sheep has almost a square body shape with the rump height slightly greater than the wither height. The chest depth and shoulder width of ewes were 34.50 cm and 22.72 cm respectively, whereas those of males were 36.17 cm and 23.75 cm. In both sheep genders, the hip width (ewes 21.92 cm, rams 22.91 cm) was lower than the shoulder width. The chest and shin perimeters of females were 98.72 cm and 9.31 cm respectively, whereas those of males were 103.25 cm and 10.91 cm. The most significant correlation and statistical significance were recorded in relation to the measured wither and rump heights (r = 0.856 for females, r = 0.856 for males) due to their constant increase during the growth and development of sheep. Conversely, the measurements of rump heights and chest perimeters did not indicate any correlation (r = −0.028 for ewes, r = 0.004 for rams).

Evaluation of the microbiological quality of some fresh dairy products with Soleris® Automated System

Abstract

The manufacture of dairy products is an important sector of the food industry. From milking to processing, a number of hygiene rules must be strictly followed. During processing, dairy products can be contaminated with different microorganisms, causing spoilage, infectious diseases, and alterations in the sensory characteristics. There are strict requirements for the quality assurance of milk products. In spite of this, there occur infections linked to milk and dairy product consumption. The analysis of the microbiological quality of these products is a health concern, and it also has an economic impact. The increase and development of the global market of processing technologies require rapid monitoring and controlling systems for food products. In our study, we investigated the microbiological quality of some fresh dairy products with the Soleris® test system. For instrument setting, calibration curves were realized with test bacterial strains. With known initial microbial load of the samples, the microbial growth versus time was measured by the above-mentioned system. The occurrence of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus was evaluated in ten dairy products. Results obtained by the Soleris system showed that the system is efficient for this purpose. Calibration curves with high correlation coefficients permitted the quantitative determination of the aimed bacteria in the dairy product samples.

A Comparison of Antioxidant Properties of Two Apple Cultivars

Summary

The apple (Malus domestica Borkh.) possesses a number of health-promoting properties. The main beneficial effects of apple fruits on human health are associated with the antioxidant properties of components synthesising in apple fruits during their growth and development. Phenolic compounds and flavonoids are such components that contribute significantly to the antioxidant capacity of fruits, thus enhancing their health properties. The purpose of this study is to compare the antioxidant properties (namely antioxidant capacity, ascorbic acid, total phenolic and flavonoid contents) of the ‘Idared’ and ‘Braeburn’ apple cultivars, grown under optimal growing conditions in the Goražde area. Ascorbic acid contents were estimated using the 2.6-dichlorophenolindophenol titration method, whereas total phenolics were determined using the Folin-Ciocalteu method. Furthermore, total flavonoids were determined using the aluminium chloride colorimetric assay, whereas the ferric reducing/antioxidant power assay was used to determine the total antioxidant capacity of the apple fruits examined. The average values of the ascorbic acid, the total phenolic and flavonoids contents, and the total antioxidant capacity of the ‘Idared’ apples under consideration were 8.09 mg 100 g−1, 34.56 mg gallic acid equivalents 100 g−1, 12.62 mg catechin equivalents 100 g−1 and 323.28 μmol Fe2+ 100 g−1of fresh weight, respectively. The average values of the total phenolic and flavonoids contents, as well as the antioxidant capacity of the ‘Braeburn’ apples examined were as follows: 8.89 mg 100 g−1, 33.4 mg gallic acid equivalents 100 g−1, 13.56 mg catechin equivalents 100 g−1 and 367.01 μmol Fe2+ 100 g−1 of fresh weight, respectively. The analyses performed indicate that the differences recorded in the parameter values between the apple cultivars ‘Idared’ and ‘Braeburn’ were statistically non-significant. A correlation data analysis confirmed that phenolic compounds are the carriers of the antioxidant activity of apples.

Examination of the selenium content of wheat grasses produced in different soil types in Csik Basin

Abstract

In the course of the research, we determined selenium and dry matter content of 35 wheat grass and 35 wheat seed samples. The selenium content of the preparation plant probes was measured by spectrofluorimetric determination (λexcitation = 380 nm, λemission = 519 nm) of the resulted piazselenol complex. It was established that between the selenium content of the wheat grass and wheat seed the correlation coefficient was 0.36 at p = 0.05 level, which indicates a medium-close correlation. Similarly, there was a medium-close correlation between the selenium content of the wheat grass calculated on dry-matter basis and total selenium content of the wheat, with a correlation coefficient of 0.40 at p = 0.02 level. Afterwards, beside the selenium content, we measured the selenomethionine content by ion-exchange chromatography and highperformance liquid chromatography, and the organic selenium content was calculated. A very close correlation was established between the total selenium, selenomethionine and calculated organic selenium content of wheat (the correlation coefficients were between 0.92 and 0.99 at p = 0.01 level). The correlation between the selenomethionine content of wheat grass and wheat seed was very weak (r = 0.23).

Flour quality and kernel hardness connection in winter wheat

Abstract

Kernel hardness is controlled by friabilin protein and it depends on the relation between protein matrix and starch granules. Friabilin is present in high concentration in soft grain varieties and in low concentration in hard grain varieties. The high gluten, hard wheat our generally contains about 12.0–13.0% crude protein under Mid-European conditions. The relationship between wheat protein content and kernel texture is usually positive and kernel texture influences the power consumption during milling. Hard-textured wheat grains require more grinding energy than soft-textured grains.

The aim of our research was to determine the possible relationship between kernel hardness and various other parameters of the our (dough visco-elastic characteristics, wet gluten, water absorption, our recovery, alveograph). We used Perten SKCS 4100 to determine the kernel hardness, while the Perten 3303 mill was used to establish Particle Size Index (PSI). Registered and widely used Hungarian wheat varieties (7 of HRWW and 4 of SRWW) were applied in the study. Twin correlations were used to determine the relationship among the various traits.

According to the results, there is a very strong correlation between milling energy and kernel hardness (r = 0:99): The correlation between hardness index and the examined our parameters was also significant (r = 0:81–0:87). We found strong correlation between the milling energy and water absorption (r = 0:88) of our. The associations found in this study will help the better understanding of the technological aspects concerning wheat grain and our quality.

Lycopene and flesh colour differences in grafted and non-grafted watermelon

Abstract

The experiment was carried out in three regions in Hungary (Jászszentandrás, Cece, Újkígyós) in 2013 to determine the fruit quality of grafted watermelon (Citrullus lanatus Thunb.). The “RX 467” seedless watermelon variety was grafted on two commercial rootstocks “FR STRONG” [Lagenaria siceraria (Mol.) Standl.] and “RS 841” (Cucurbita maxima Duchesne × Cucurbita moschata Duchesne). The lycopene and flesh colours are important quality characteristics even of the selfrooted and grafted watermelon. Some differences can be attributed to different environments, technological methods and to the type of rootstockscion combination. Lycopene is a strong antioxidant; therefore, we considered to examine the content change. Regardless of growing location, the lycopene concentration and the chroma (C*) showed the best result in the case of interspecific rootstock. The result also showed that in two regions (Jászszentandrás, Cece) we can find negative correlation between the lycopene concentration and the L* value of the flesh colour.
