On the usage of Tartrazine (e102) in certain food products and estimation of potential daily intake
The inclusion rate of the synthetic food dye Tartrazine E102 in 6 products from 2 categories of
food products - āFresh, non-alcoholic and flavored beverages - sodas,ā and āSnacks and nuts with
salted crustā was studied using the photo-colorimetric method. The acquired data served to
estimate the hypothetic daily intake of this additive, in relationship with the Romaniansā
consumption habits. The results revealed that: inclusion rate in āMulti-fruit sodaā product was
87.2-88.5% lower than the maximum residual admitted level (20 mg/liter product); daily intake
level through a portion of āMulti-fruit sodaā (500 ml in adults and 200 ml in children) reached
1.28-1.42% of the maximum tolerated doze in children, respectively 0.96-1.39 % of it in adults;
tartrazine inclusion rate in āCheese snackā product was 34.0-47.2% lower than the maximum
residual admitted level (100 mg/kg product); calculation of the daily intake through one portion of
āCheese snackā (120 g in adults and 50 g in children) reached 1.17-1.47% of the maximum
tolerated doze in children and 1.06-1.47% in adults. Despite the fact that inclusion levels and intake
values have not been exceeded, the cumulative effect should be considered when multiple food
products containing tartrazine are consumed, knowing this additive is one of the most incriminated
factors in the onset of allergenic and irritating conditions in adults, respectively of attention deficit
and hyperactivity syndrome in children
Phenolic and Total Flavonoid Contents and Physicochemical Traits of Romanian Monofloral Honeys
Since ancient times, honey has been appreciated not only for its sensorial traits, but also for the observed effects in rejuvenation and treatment against several bad health conditions, when used externally or internally, along with other beehive products, such as pollen, propolis and royal jelly. Today, it is known that such effects are generated by compounds bearing antimicrobial, anti-inflammatory, and antioxidative features (enzymes, polyphenolic molecules). The purpose of this study was to assess the total phenolic and flavonoid contents of 28 samples of Romanian raw monofloral honey (acacia; linden; rapeseed, sunflower and mint), and to establish their correlations with several qualitative parameters. Pearsonās test revealed a strong positive correlation between total phenolic content and total flavonoids (r = 0.76) and color intensity (r = 0.72). For total flavonoid content, correlations were strongly positive with color intensity (r = 0.81), ash content (r = 0.76) and electrical conductivity (r = 0.73). The relevant levels of polyphenols and flavonoids identified in the analyzed honey types demonstrate its antioxidant potential, with essential nutritional and sanogenic features in human nutrition
Quality assessment of raw honey issued from Eastern Romania
Romania is known among the main European honey producers, due to the variety of
landforms as well as the diversity of the flora. Thirty-four honey samples of the acacia, linden
and multifloral types, produced in eastern Romania and collected during 2013ā2018, were physico chemically analyzed using methods provided by the national and EU standards. The results of
water-insoluble solids, color and refractive index were found to be 0.023ā0.131%, 0.3ā76.4 mm
Pfund and 1.485ā1.499, respectively. The moisture content ranged between 15.20% and 20.77%,
solid substances content ranged between 79.23% and 84.80% and total soluble substances content
ranged between 77.83 ā¦Brix and 83.26 ā¦Brix. The obtained values of specific gravity were from
1.414 to 1.450 g/cm3
, pH ranged from 3.673 to 5.503 and free acidity ranged between 2.4 meq and
50 meq kgā1
. The ash content and the electrical conductivity varied between 0.030 and 0.543% and
130 and 679 ĀµS cmā1
, respectively. Pearson0
s correlation analysis showed an intense association of
the ash content with electrical conductivity (r = 0.81). Our findings reveal the qualitative level of
Romanian honey and the variation in quality parameters due to factors such as geographical region,
climatic conditions, botanical origin and handling or storage conditions
Research regarding effect of monosodium glutamate on health of laboratory mice
Utilization of food additives represents a technique which is more and more present in modern
food industry but this one doesnāt have always favourable effects on human organism but on contrary.
The study carried out by us aimed to present the impact of one of the most controversial food additives,
monosodium glutamate, on organism of laboratory mice and implicit on human organism. Research
were carried out on three mice batches, each with 10 individuals, from which one was the control
batch LM and two experimental batches LE1 and LE2. Mice from LM received specific nourishment
and the animals belonging to the other two batches received besides that specific food different doses
of monosodium glutamate, respectively 3% at batch LE1 and 5% for batch LE2. Experimental mice
have enjoyed water at their discretion during the whole research period. Research took place during a
period of 28 days. In the whole period has been monitored feed consumption, dynamic of corporal
mass, and at the end were gathered blood samples for study of some haematological indexes and some
parameters connected with blood biochemistry. At the end of the study we observed that MSG induced
higher corporal mass gains with 38.4ā59.4% at mice from experimental batches face to the ones from
control batch, and feed consumption was higher with 7.5ā13.8% at experimental batches face to the
same reference batch ā fact which leads to obesity. Blood analysis show the fact that at animals from
experimental batches was recorded a qualitative degradation of blood and very high deviations for the
majority of analysed sanguine biochemical parameters. Those aspects show a severe degradation of
miceās health state which formed the experimental batches
The chemical composition and polluants content of some ecological and conventional green forage sources for dairy cow feed
The quality of feed is very
important in dairy milk production. The
aim of the current paper was a
comparative characterisation in terms of
crude chemical composition, Ca and P,
heavy metals (Pb, Cd, Zn, Cu), nitrates,
nitrites and pesticides, for the natural
meadow and green alfalfa, cultivated in
ecological and conventional systems,
utilised for feeding dairy cows. Sampling
and analysis were performed according to
established standards and working
methods: drying for dry matter (DM);
calcination for crude ash (C Ash);
Kjeldahl method for crude protein (CP);
Soxhlet method for crude fat or ether
extract (EE), spectrophotometry for P,
nitrates and nitrites; atomic absorption
spectrometry for Ca, Pb, Cd, Cu and Zn;
gas-chromatography for pesticides. For
alfalfa, the highest values in the
ecological system were for C Ash
(12.68%), EE (2.50%), NFE (35.78%)
and Ca (1.79%). For the natural meadow,
the highest values in the ecological
system were for DM (25.72%), OS
(89.32%), EE (2.76%), NFE (45.27%)
and Ca (0.70%). The toxic heavy metal
content was below the limits allowed
(1 mg/kg Cd and 30 mg/kg Pb). For Pb
the values determined from the two feeds
were between 0.06 mg/kg and 0.16 mg/kg
and for Cd between 0.007 mg/kg and
0.02 mg/kg. The pesticides residuum was
under the detection limit of 0.05 mg/kg
DM for organo-chlorinated pesticides and
0.001 mg/kg for organo-phosphoric
pesticides. All the studied forages were
safe regarding pollutants (heavy metals,
nitrites, nitrates and pesticides), but
statistical differences existed between the
production systems, such that the
ecological system seems to be better
Effect of Gender and Muscle Type on Fatty Acid Profile, Sanogenic Indices, and Instrumental and Sensory Analysis of Flemish Giant Rabbit Meat
The aim of this study was to represent quality characterization, by gender and muscle type, of rabbit meat from the Flemish Giant (FG) breed, following the fatty acid profile, sanogenic indices, and instrumental (color and texture) and sensory analysis. The biological material comprised 40 rabbits (20 females and 20 males) whose Longissimus dorsi (LD) and Semimembranosus (SM) muscles were sampled. Compared to female samples, the meat from males was more qualitative in terms of higher ratios of polyunsaturated vs. saturated fatty acids and proportions (+42%) of Essential and Desirable Fatty Acids (+21.6% EFA; +6.7% DFA). Also, the Atherogenic Index (AI) and Thrombogenic Index (TI) were better in males (ā37.1% AI; ā34.3% TI), as were the ratio of hypocholesterolemic/Hypercholesterolemic fatty acids (+27.8%) and the Nutritive Value Index (NVI, +11.6%). The Polyunsaturation Index (PI) was higher for females (+57.5%), with the widest differences in hind leg muscles (SM muscles), while the omega-6/omega-3 fatty acid ratio was also better (+11.3%). Female meat was more tender due to lower shear force (ā6.2%ā¦ 9.3%) in both muscles. Female meat was less pigmented than that of males, while the overall sensory attributes were better scored in male samples (+3.1%ā¦ +7.1%) (p < 0.01). The meat of males proved to be more sanogenic (richer in EFA and DFA, with a better h/H ratio and NVI, while AI and TI were lower). We would recommend slaughtering 3ā4 weeks earlier in females vs. males to avoid excessive fat deposition and, consequently, the development of unfavorable sanogenic indices for consumer health

Comparative Assessment of the Nutritional and Sanogenic Features of Certain Cheese Sorts Originating in Conventional Dairy Farms and in āMountainousā Quality System Farms
In order to highlight the influence of cattle farming systems on dairy products, assessments were carried out on certain varieties of cheeseāmarked with the āMountain productā quality label in comparison with those conventionally produced ones not bearing the quality label. The study was carried out using products obtained from raw milk issued from seven farms and transformed into cheese in four small dairy factories from the mountainous area of Dornelor Basin, Suceava County, Northeastern Romania. The analyzed cheese issued from the āmountainā production system were āCÄlimaniā Schweizer, āCÄlimaniā CaČcaval, āCÄlimaniā smoked CaČcaval, and āCÄlimaniā Telemeaāsalty brined cheese. Both the āMountain cheeseā and conventional cheese samples produced throughout the same shift were collected and kept under refrigeration conditions until laboratory analysis in order to compare the production systems. The physico-chemical analysis revealed higher amounts of minerals (2.8 to 10.7% Ca; 2.8 to 9.5% P; 12.3% to double the amount of Fe, p Enterobacteriaceae family species were identified in āMountain cheeseā, while they were absent from conventionally processed cheese, knowing the raw matter milk is thermally treated at ultra-high temperatures in the latter ones. In the āMountain cheeseā, such microorganisms were found within the safety regulation limits and contributed to providing flavor, taste, color, and specific texture, making it superior in terms of sensorial quality compared to the conventionally produced cheese
THE EFFECTS OF USING SOME ENERGETICS SYRUPS ON BEES DEPRIVED FROM NATURAL PICKING
Recipes used for supplementary bee feeding and their consequences on colonies development are still the subject of numerous research worldwide. This study examines the effects of using three types of energy syrups (2:1 sugar syrup, respectively corn syrup and syrup of enzymatic inverted sugar) on some morpho-productive indicators of bee families maintained in bee lofts (deprived from natural picking). The values of these parameters (the amount of wax produced in 9 weeks, the amount of food supplies at the beginning and end of the cold season) were statistically processed and then compared with those of some bee families maintained in the field (with access to natural picking). Regarding the bees deprived from natural picking, those fed with the 2:1 sugar syrup recorded the lowest values, while those fed with enzymatic inverted sugar syrup recorded the highest values of the monitored indicators. The values of these morpho-productive parameters were higher for the bee families in the field than those obtained from the bees from lofts, due to the quality of the food and the stress caused by the restriction of flight
