Contribuţii la cunoaşterea calităţii unor sortimente de ulei de măsline comercializat pe piaţa municipiului Iaşi

Olive oil is a food rarely consumed by Romanian peoples, even it if hasa varied range of utilisations, and consumed in moderate quantities is beneficial to human organism. The aimof the current paper to establish the main quality characteristics of some olive oil assortmentssold onIaşi City market and their comparison in according with the values of actual standards. Olive oil samples gathered from two different producers (Aand B) were achieved from Iaşi City market.The determined physical-chemical propertieswere: humidity, density, acidity value, saponification value, iodine value,and peroxide valu

Chemical features, cholesterol and energy content of table hen eggs from conventional and alternative farming systems

This study was carried out to investigate the effect of conventional farming systems for laying hens (standard cage batteries) and new alternative systems (improved cages and free range), approved by European Union (EU) poultry welfare legislation, on the chemical and nutritional quality of table eggs. The biological material consisted of eggs laid by 1200 Lohmann Brown hens, aged 27 weeks, fed similarly (a corn-wheat-soymeal diet). Conventional AOAC methods were used to analyse the eggs, and gross energy was calculated based on organic matter energy. All data were subjected to ANOVA statistical computation. The eggs produced in conventional cages compared with those laid in free-range farming conditions, presented significantly higher concentrations of total lipids (11.40 ± 0.65 g/100 g vs. 10.78 ± 0.87 g/100 g), cholesterol (211 ± 6.31 μg/egg vs. 202 ± 7.79 μg/60 g egg) and gross energy (0.36 ± 0.007 MJ/egg vs. 0.35 ± 0.012 MJ/egg). Consequently, it could be stated that under similar dietary conditions, the cage-free system influenced hens to produce eggs with a higher nutritive value than in the other systems.Keywords: Battery cages, chemical composition, dietetic value, improved cages, free-range, laying hen
