This work had as thematic the study in analysis of foods from the perspective of the nutrition professional. The objective of the research was to seek the training of this professional for the then analysis of the performance in quality control and formulation of products, with the perspective of assistance to projects carried out on site. This research was conducted in a community cafeteria located in a university in the interior of the State of Mato Grosso do Sul - Brazil. As a data collection tool, preparation technical sheets were used in which costs were collected, the preparation order, and the nutritional value provided. Sensory observation was used as an analysis of the data in order to measure and analyze and interpret the reactions of food and material characteristics. It appears that with the identification, attributions and activities developed by a nutritionist in the area, it became possible to analyze the processing of raw material and industrialized food products, according to the needs presented by the site. As for the points not reached were not due to any other factors than those related to the specificities of the research site, which did not prevent the acquisition of theoretical, practical, scientific, social and environmental knowledge of the points concerning the area of action of the nutritionist professional within the field of food science.

Subject. The article considers the quality control over cash flow statements. Nowadays, audit procedures apply rather simple analytical tools to assess the reliability of this type of accounting reports. There is, therefore, an objective need to develop them. Objectives. The aim is to assess the quality of cash flow statements for the 5-year period from 2014 till 2018, and prove the interrelation between the scale of manipulation in accounting statements and the economic situation in the country and in the sector. Methods. The study employs theoretical and practical works of foreign and Russian scientists on accounting misstatements. Results. We use a large amount of information to develop and test a methodology for checking the quality of accounting reports, including the assessment of credibility of a statement as a whole, as well as its pats, i.e. cash flows from operations, investments, and financial transactions. Conclusions. It is recommended to use the offered methodology by audit companies and financial analysts to find out companies involved in accounting manipulation.

Background:Cinnarizine, an antihistaminic drug, is commonly formulated in combination with domperidone and with paracetamol for treatment and prevention of motion sickness and migraine.Objective:The aim of this work was to develop new, simple, precise and selective chromatographic methods (RP-HPLC and TLC-densitometric methods) for the determination of these drugs. These methods can be used as analytical tools in the routine examination in quality control laboratories.Methods:The first method was RP-HPLC method, the separation was carried out on an Inertsil® ODS- 3V C18 column (250 mm × 4.6 mm, 5 µm) using a mobile phase composed of methanol: acetonitrile (45: 55, v/v) at a flow rate of 1 ml/min. The detection was carried out at 220 nm. The second method was a TLC-densitometric method where the studied components were separated using a developing system composed of toluene: ethyl acetate: methanol: triethylamine (5: 4.3: 0.7: 0.5, v/v/v/v) on TLC silica gel 60 F254 plates, followed by densitometric scanning at 270 nm.Results:In RP-HPLC method, the peaks were sharp and well separated, the retention times were 5.25, 3.48 and 2.78 min, for cinnarizine, domperidone and paracetamol, respectively. Linearity was obtained over the concentration ranges 1-22, 0.75-16.5 and 25-550 µg/ml, for cinnarizine, domperidone and paracetamol, respectively. In TLC-densitometric method, good separation of spots and linear relationships were achieved over the concentration ranges of 0.2-2, 0.15-1.5 and 5-50 µg/spot, for cinnarizine, domperidone and paracetamol, respectively. Method validation was conducted according to ICH guidelines in terms of linearity, accuracy, selectivity, precision and robustness.Conclusion:The developed methods were applied for the determination of the cited drugs in tablets containing binary drug mixtures. The methods are simple and precise and can be used for routine analysis of the labelled drugs in combined dosage forms in quality control laboratories.

2D Imaging

Neutron imaging and tomography allow observing the structure of large objects (from few to hundred centimeters) at a resolution around 100 μm. This nondestructive method is based on the detection of the transmission of a neutron beam through an object in 2D (imaging) or 3D after rotating the sample (tomography). The components of the object attenuate the neutron beam differently, depending on their composition, and produce accurate pictures of objects which give information about their structure. Neutron imaging has been used for quality control purposes in industries (aircraft, motor engineering...), but also find application from materials sciences (fuel cells, lithium batteries) through earth science (petrology, geology) to cultural heritage. More recently studies have been performed on food science topics.

Objectives: The aim of this work was to develop and validate new, simple, accurate, and selective spectrophotometric methods (derivative and derivative ratio spectrophotometric methods) for the determination of these drugs. These methods can be used as analytical tools in routine examination in quality control laboratories. Methods: The first method was derivative method in which the first derivative method (1D) for determination of PCM and the second derivative method (2D) for determination of CIN. The second method was the first derivative ratio spectrophotometric method (1DD) for determination of CIN and PCM. Results: In first method, the first derivative spectrum (1D) of PCM where PCM was determined by measuring the amplitude of the valley at 235 nm while CIN showed zero crossing spectrum, and the second derivative spectrum (2D) of CIN where CIN was determined by measuring the amplitude of the peak at 287.5 nm while PCM showed a zero value. In the second method, the first derivative ratio spectrophotometry (1DD) for CIN and PCM determination, where the amplitude at 290 and 291 nm, was selected for the determination of CIN and PCM, respectively. Conclusions: The developed methods were applied for the determination of the cited drugs in tablets containing binary drug mixture. The methods are simple and precise and can be used for routine analysis of the labeled drugs in combined dosage forms in quality control laboratories.
