Comparative analysis of physical, morphological, and mechanical characteristics of eggs from three pheasant subspecies.

The profitability of pheasants breeding is influenced by many factors, but eggs quality is considered as the backbone for successful pheasant breeding. The objective of this study was to determine and compare various quality characteristics (physical, morphological, and mechanical) of eggs from three pheasant subspecies: common pheasant (Phasianus colchicus colchicus), Mongolian pheasant (Phasianus colchicus mongolicus), and black pheasant (Phasianus colchicus vs. tenebrosus).

Effect of ultrasound pre-treatment and drying method on specialized metabolites of honeyberry fruits (Lonicera caerulea var. kamtschatica).

Honeyberries are rich in various nutrients (eg. minerals, and vitamins) and bioactive compounds (eg. polyphenols).

Mechanical properties of ten-egg boxes made of different materials.

This study was conducted to evaluate mechanical properties of ten-egg boxes, which are the most commonly used egg boxes in many countries of Central and South-Eastern Europe. Six ten-egg boxes were tested, two made of cardboard, two made of expanded polystyrene and two made of general purpose solid polystyrene, each from a different producer. There were no significant differences in basic dimensions between tested boxes of various materials, while the significant differences were occurred in weight and box wall thickness.

Antioxidant Potential of Fruit Juice with Added Chokeberry Powder (Aronia melanocarpa).

The purpose of this study was to determine the possibility of using chokeberry powder as a supplement in apple juice to increase the nutritional value of the final product with the aim of developing a new functional food product. Also, to determine the influence of ultrasound assisted extraction on the bioactive compounds content, nutritional composition and antioxidant potential of apple juice with added chokeberry powder. The juice samples with added chokeberry powder had higher antioxidant capacity, irrespective of the extraction technique used.

Variation in the bioactive compound content at three ripening stages of strawberry fruit.

During the harvest season of two consecutive years, five strawberry cultivars ('Arosa', 'Elsanta', 'Marmolada', 'Miss' and 'Raurica'), grown in the continental part of the Republic of Croatia, were examined. Strawberry fruits quality was evaluated by individual phenol compounds, individual anthocyanins and fruit color. Fruits were harvested in three different periods.
