In this respect, 772 samples of wheat from the 2005-2016harvests were analyzed in terms of physical and chemical quality parameters, namely: Hectolitre mass (HM, Kg/hl), Moisture (M, %), Protein content(PC, %), Wet Gluten (WG, %), FallingNumber (FN, s), Gluten Deformation Index (GDI, mm) and Gluten Index (GI), the latter two being given special attention. Following the milling of the wheat on pilot mill, alveographic parameters were determined on 419 samples,namely: Resistance (P, mm), Extensibility (L, mm), alveographic Mechanical work (W, 10E-4 J/g) and P/L ratio. Also, for 35 samples, baking tests were performed in order to evaluate the bread volume (ml/100 g). The results showed that the Gluten Index parameter alone is not a predictive criterion fo...
Rheological quality of wheat dough prepared from 130 variety, stream, and commercial wheat flour ... more Rheological quality of wheat dough prepared from 130 variety, stream, and commercial wheat flour samples (wheat harvest 1999, 2000 and 2001) was assessed with alveograph. Spectra of all samples were measured on spectrograph NIRSystems 6500. Calibration equations with cross and independent validation for all rheological characteristics were computed by NIR Software ISI Present WINISI II using MPLS and PLS methods. The quality of the prediction was evaluated by the coefficient of correlation between the measured and the predicted values from cross and independent validation. A statistically significant dependence between the predicted and the measured values (with probability P < 0.01) was determined in P (elasticity) and W (energy) characteristics in the case of cross validation only in the commercial flour sets. P (with P < 0.01) and W (with P < 0.05) were successfully predicted by independent validation in the set of all samples.

In this sense, we undertook a statistical processing of the data presented in the study, to analyze the distribution of the main areas of the most powerful Romanian brands. Our results showed that the most successful brands belong to different Romanian food branches, in that they represent secondary and tertiary processing products of raw materials, derived from agriculture or zootechnics. The number of industrial products brands is relatively small (9, representing 18% of total), the associated trade mark services sector is dominated by banks, representing 10% of the total marks. 16% of successful brands belong to Romanian mass-media. Also, best valued branch in the top is the alcoholic beverages one. The most brands in top 50, concerning alcoholic beverages, were valued in the top half of the ranking.

In this respect, were analysed 19 samples of flour obtained from Romanian wheat, determining the protein content, wet gluten content and gluten index. At the same time were carried out baking tests corresponding to the 19 loaves of bread and were determined the parameters volume and the height / diameter ratio (H /D). The results showed that the best predictor for the bread quality parameters: volume and H / D ratio, is the gluten fraction of the gluten index parameter which remains on the sieve (highly significant positive correlation r = 0.79***, respectively r = 0.73***). Gluten index parameter correlates insignificantly with bread volume (r = 0.18) and significantly with the height / diameter ratio (0.51*). In conclusion, the p...

In this respect, we analyzed 36 samples of bread made from Romanian flour after a standard recipe. The results showed that the volume of the finished products was positively correlated with the intensive kneading time and the proofing time, and negatively with the amount of added water. Porosity of bread increased significantly with the bench proofing time. Elasticity increased significantly as the temperature of dough and the bench proofing time increased and also increased significantly with increasing of added water amount. The main technological parameters that influenced the fractal dimension of the p...

In this respect, there have been analyzed the following physical and chemical parameters: Hec tolitre mass (kg/hl), Moisture (%), Protein content (%), Wet gluten content (%), Falling Number (sec), Gluten deformation (mm), Gluten Index, as well as the Content of kernels attacked by Fusarium (%). The Fusarium attack ranged from 0.1% to 4.5% and was characterized by very high variability. The evaluation of Fusarium attack was made through the Spearman statistical test, which showed its significant influence on the amylase activity of wheat (expressed by the parameter Falling Number, r = -0.22 *) and on the proteolytic activity (expressed by the Gluten deformation, r = -0.28 *).

Afterwards, the wheat samples were ground on the Chopen pilot-type mill and the al veografic parameters were determined from the resulting flour: Resistance (P, mm), Extensibility (L, mm), Mec hanical Work (W, 10E-4J), Elasticity index (Ie,%), Gluten Extensibility index and the P/L report. The wheat samples taken for analysis were scanned using a commercial scanner, at a resolution of 200 dpi. The obtained results were examined with a specific software, used for the analysis of ImageJ image. For each image we determined the color histogram with the specific parameters: R, G, B, Brightness and Fractal Dimension. Our results have shown highly significant correlations between the color histogram parameters (Brightness, R, G, B) and th...

In this regard there were purchased 20 samples of flour from 13 manufacturers. Quality parameters analyzed were: Moisture (%), Protein content (%), Ash content (%), Water absorbtion (%), Total combined Yeasts and Molds count (CFU/g) and the number of days until the deadline of the shelf life. The analyzed flours were characterized by the following variation ranges of the parameters: Moisture (%) 10.9 14.4, Protein content (%) 10.0 15.7, Ash content (%) 0.40 1.59, Water absorbtion (%) 57.0 61.9, Yeast and molds (CFU/g): 10-410, and number of days until the deadline of the shelf life: 9-326. The results showed that there are no significant correlations between analyzed parameters and the content of yeasts and molds. This suggests that the dynamics of yeasts and molds population in packed flours is dependent primarily on the process...

The investigation of this potential starts from the transformation of oat kernel into flour and ends with obtaining the wheat-oat mixtures bakery products. Oat flour contains no gluten but provides significant amounts of lipids and fibers with important nutritional value. β-Glucans from oat lower blood cholesterol and decrease blood glucose level. The lack of gluten and the fibers intake limit the oat flour potential for use in bakery, the products obtained exclusively from oat, being characterized by an unacceptable volume and texture. However, using conventional technologies and addition of whole oat flour up to 30% to wheat flour (WF), bakery products with good sensory characteristics accepted by consumers can be obtained. These products are characterized by a higher nutritional profile than those obtained exclusively from WF and contribute to the diversificat...

The results showed that IDK had a significant influence on all the quality parameters of wheat, with the exception of Falling Number. The increase of IDK very significant decreased the values of: Hectolitric mass (r = 0.407 ***), Moisture (r = 0.263 **), Gluten Index (r = 0.297 **) and increased very significant the values of Protein content (r = 0.477 ***), Wet gluten (r = 0.398 ***) and Gluten deformation index (r = 0.620 ***). SWK was correlated negative very significant with Falling Number (r = -0.602 ***) and positive significant with Moisture (r = 0.294 *). Also, between IDK and SWK it was established a significant negative correlation (r = -0.337 *). The results showed that the two parameters had a notable influence on the enzymatic activity of wheat. Thus, IDK significantly influenced p...

The products resulting from the two antagonistic metabolic processes (anabolism and catabolism) are continuously introduced or eliminated in blood, because blood maintains the connection between different organs and tissues and between different cells and digestive organs. As a consequence, we may consider that the entire composition of blood deviations from normal (deviations that surpass sanguine homeostasis), are significantly correlated with body pathology. Moreover, blood is one of the most accessible tissues in the human body, and it can be collected and analyzed without harming the patient.

In this regard, there were analysed: soil pH and soil temperature at the moment of sowing. The garden pea, Bördi variety, was randomly sown in early April, on 18 plots, which formed 6 experimental variants (three plots on variant). First variant V1 was the control. Variants V2, V3 and V4 have been fertilised with Universol Blue (337.5g; 421.875g; 506.25 g/variant), and V5, V6 have been fertilised with Ferticare I (540g; 607.5g/variant). After harvesting, there were determined the statistical estimates of the peashells number/variant, estimates of total peashells weight/variant and individual peashells weight/variant. The results showed that soil pH values were in the weak acid range, pH of variants V2, V3 and V4 being slightly more acidic (6.59) than pH of V5 and V6. Soil tempe...

For all bread assortments were evaluated CIELab parameters, L*, a*, b*. Acrylamide (AA) analysis in bread samples was performed by gas chromatography tandem mass spectrometry (GC/MS/MS) using a gas chromatograph TRACE GC ULTRA coupled to triple quadrupole mass spectrometer, TSQ Quantum XLS (Thermo Fisher Scientific, USA).The results revealed that the lowest values of AA content (26.92 to 33 mg/kg) were found in Simple bread and the highest values (79.22 to 88.5 mg/kg) were found in Onion bread for both types of flour used. AA level doesn’t correlate with the color, but with the carbohydrate content of the ingredients.

Most nutritionists recommend increasing dietary inulin levels due to an impressive number of potential therapeutic effects on the health of the gastrointestinal tract, especially colon, but do not exclude a number of systemic effects related to the prevention of certain cancers and to the reducing of inflammatory processes in the body. However, there are medical studies that correlate fructolysis in the small intestine (possible for oligofructans of up to 10 carbon atoms) with negative effects, characteristic of irritable bowel syndrome. The most common method of obtaining inulins is the extraction from chicory in a manner similar to sugar obtaining.

In this regard, a number of 62 wheat flours, coming from Romanian wheat, were additivated with variable amounts of calcium lactate, ranging from 10 to 300 g/100 kg. Both the control flours and the additivated flours with calcium lactate have been evaluated in terms of rheology, using the alveographic method. The results showed that treatment with calcium lactate caused a very significant increase of following parameters: Resistance (P, mm; t= 4.864***), dough capacity to absorb Mechanical work (W, 10 J/gram; t = 6.990***) and the ratio between Resistance and Extensibility (P/L; t=7.174***). Elasticity parameter increased significantly in dough treated with calcium lactate, compared to control flours. Also, treatments with calcium lactate caused a very significant decrease of some parameters, such as: Extensibility (L, m...

Our results were included into a mathematical simulation, in order to elaborate predictive models for estimating the value of the alveographic parameters - mechanical work (W), resistance (P) and extensibility (L) - based on main physical and chemical quality parameters. Two predictive multifactorial models were developed, having the multiple determination coefficients (R 2 ) bigger than 0.965, for each of the alveographic parameters. As for the mechanical work (W), all the physical and chemical parameters of the flour may be significant regressors for the predictive simulation of its value. The extensibility (L) parameter can also be estimated, taking into consideration all the...

The garden peawas randomly sown on 36 plots, which formed 12 experimental variants. The V1-V6 variants were unbacterized and V7-V12 variants were bacterized (factor A). Variants V1 and V7 were unfertilized controls. Variants V2, V3, V4 and V8, V9, V10, were fertilised with Universol (337.5 g; 421.875 g; 506.25 g/variant), while V5, V6 and V11, V12 were fertilised with Ferticare (540 g; 607.5 g/variant) (factor B). Dispersional analysis for the bifactorial experiment (2×6) placed in subdivided plots, highlighted that there were significant differences between the peashells production (t/ha) in bacterized variants (experimental F distribution 532.411> theoretical F 98.5; p<0.01). Significant differences were also obtained between the production of peashells (t/ha) in fertilized variants (experimental F distribution 53.55>F theoretically 4.10; p<0.01). The interaction between the two bacterization-fertilization (AxB) factors was not significant. In all variants, Ferticare fertilizer was found to be significantly more effective than Universol. The bacterization effect was very significant, the production of peashells (t/ha) increased by 1.002 t/ha and 116.542%, respectively, compared to unbacterized variants (7.059 t/ha vs. 6.057 t/ha).

Spectra of all samples were measured on spectrograph NIRSystems 6500. Calibration equations with cross and independent validation for all rheological characteristics were computed by NIR Software ISI Present WINISI II using MPLS and PLS methods. The quality of the prediction was evaluated by the coefficient of correlation between the measured and the predicted values from cross and independent validation. A statistically significant dependence between the predicted and the measured values (with probability P < 0.01) was determined in P (elasticity) and W (energy) characteristics in the case of cross validation only in the commercial flour sets. P (with P < 0.01) and W (with P < 0.05) were successfully predicted by independent validation in the set of all samples.

Our results were included into a mathematical simulation, in order to elaborate predictive models for estimating the value of the alveographic parameters - mechanical work (W), resistance (P) and extensibility (L) - based on main physical and chemical quality parameters. Two predictive multifactorial models were developed, having the multiple determination coefficients (R 2 ) bigger than 0.965, for each of the alveographic parameters. As for the mechanical work (W), all the physical and chemical parameters of the flour may be significant regressors for the predictive simulation of its value. The extensibility (L) parameter can also be estimated, taking into consideration all the...

The garden peawas randomly sown on 36 plots, which formed 12 experimental variants. The V1-V6 variants were unbacterized and V7-V12 variants were bacterized (factor A). Variants V1 and V7 were unfertilized controls. Variants V2, V3, V4 and V8, V9, V10, were fertilised with Universol (337.5 g; 421.875 g; 506.25 g/variant), while V5, V6 and V11, V12 were fertilised with Ferticare (540 g; 607.5 g/variant) (factor B). Dispersional analysis for the bifactorial experiment (2×6) placed in subdivided plots, highlighted that there were significant differences between the peashells production (t/ha) in bacterized variants (experimental F distribution 532.411> theoretical F 98.5; p<0.01). Significant differences were also obtained between the production of peashells (t/ha) in fertilized variants (experimental F distribution 53.55>F theoretically 4.10; p<0.01). The interaction between the two bacterization-fertilization (AxB) factors was not significant. In all variants, Ferticare fertilizer was found to be significantly more effective than Universol. The bacterization effect was very significant, the production of peashells (t/ha) increased by 1.002 t/ha and 116.542%, respectively, compared to unbacterized variants (7.059 t/ha vs. 6.057 t/ha).
