AbstractAt a closer look powder is found throughout all kind of industries. Dough and sugar in the food industry, pigments in the paint industry and drugs in the pharmaceutical industry, just to mention a few. Even though powder is obviously a common substance of a product or raw materials and therefore ingredients have to be handled as a powder, none or only little work has been done to characterize their flow properties. Probably the lack on suitable measuring devices gives reason for that. Therefore a new powder viscometer has been developed. Prior to the presentation of the achieved results from that new machine, an introduction to powder properties, examples for bulk materials in the industry and a comparison of adhesive forces in bulk materials will be given.

The flavour and aroma of chillies is because of the presence of capsaicinoids. Among the capsaicinoids, 90% of the pungency is due to the presence of capsaicin (8-methyl-N-vanillyl-trans-6-nonenamide) and dihydrocapsaicin. From the perspective of the food and pharmaceutical industry, capsaicin being used as an active component, there is a need to find a quicker method of estimating capsaicin. Also it is imperative to determine and standardize a fingerprint of chilli extract of different varieties, to define a pure sample containing capsaicin by determining a marker peak for capsaicin, using HPTLC. Hence in this study capsaicin was estimated by HPLC, GC-MS and HPTLC methods. This study has successfully demonstrated a quick chromatographic separation of capsaicin by HPLC with Rt of just 2.9 min. GC-MS showed the capsaicin peak at Rt of 25.9 min. The fingerprint results of HPTLC indicated capsaicin at Rf 0.03 using Toluene: Ethyl Acetate (70:3) as mobile phase and Iodine vapours as detecting reagent. Besides, the Methanolic extracts of Capsicum annuum showed good antimicrobial activity with very negligible antioxidant properties. Byadgi chilli extract showed the most intense red brown colour with λmax at 500 nm and it thus justified its use as the most preferred one for contributing to colour in food. Keeping in mind the importance in the food industry, and monitoring of raw materials in the pharmaceutical industry, the methods of HPTLC and HPLC can be used to authenticate chilli powders available in the market and in pharmaceutical products for quick estimation of capsaicin.

This study concerns the technology and the consumer properties formation improvement of cold appetizers from silver carp in the form of a roll. Unlike traditional the developed products consist of fillet of a bighead silver carp on a skin and an original stuff from egg, vegetables and mushrooms. The researchers conducted study using conventional and special methods. They recommended to introduce gelatin in a dry powdered at the stage of roll forming form in a recipe of the developed fish rolls. A man tested fish gelatin as anew consistency regulator of the developed products. The traditional and fish gelatin use allows to increase the yield of fish cold appetizers in the form of a roll by 8.0 %. When adding gelatin, there was an improvement in consistency and sensory perception of the product as a whole. The analysis results of biological value showed that the developed dishes, being an important additional source of protein and essential amino acids such as threonine, lysine, valine, may well improve the ration balance. The fatty acids ratio in fish rolls prepared according to new recipes is close to the ideal fat in the ratio of saturated, monounsaturated and polyunsaturated fatty acids (35:45:20) and is determined mainly by the composition of fatty acids in silver carp fat. The developed production will allow to expand the range of the food industry enterprises by cold fish appetizers of high quality and food value from available fish raw materials.

Plants from the Rosacea family are rich in natural molecules with beneficial biological properties, and they are widely appreciated and used in the food industry, perfumery, and cosmetics. In this review, we are considering Rosa damascena Mill., Rosa alba L., Rosa centifolia L., and Rosa gallica L. as raw materials important for producing commercial products, analyzing and comparing the main biological activities of their essential oils, hydrolates, and extracts. A literature search was performed to find materials describing (i) botanical characteristics; (ii) the phytochemical profile; and (iii) biological properties of the essential oil sand extracts of these so called “old roses” that are cultivated in Bulgaria, Turkey, India, and the Middle East. The information used is from databases PubMed, Science Direct, and Google Scholar. Roses have beneficial healing properties due to their richness of beneficial components, the secondary metabolites as flavonoids (e.g., flavones, flavonols, anthocyanins), fragrant components (essential oils, e.g., monoterpenes, sesquiterpenes), and hydrolysable and condensed tannins. Rose essential oils and extracts with their therapeutic properties—as respiratory antiseptics, anti-inflammatories, mucolytics, expectorants, decongestants, and antioxidants—are able to act as symptomatic prophylactics and drugs, and in this way alleviate dramatic sufferings during severe diseases.

The Subject

Grinding or crushing hard raw materials is usually a primary operation which precedes the follow-up technological processes in a number of industrial sectors. A great variety of machines using different principles of fragmentation are employed in the technology of pulverization. The food industry uses roller mills, in which the main process is the shear grinding. In the animal feed industry impact machines known as hammer mills are often used. In recent years, mills have been employed that use their frontal edges for grinding or crushing during the rotation of one of two adjacent discs. The modern design disc machines used for grinding grain have resulted from long development and their operation has a relatively low noise level with reduced dust. The separation process that occurs in the gap between the active edges of the discs can be described as shear grinding and is currently the subject of attention which is focused on the specific energy consumption and fractional composition of the product of grinding.

AbstractMicrobiological control is of crucial importance in the pharmaceutical industry regarding the possible bacterial contamination of the environment, water, raw materials and finished products. Molecular identification of bacterial contaminants based on DNA sequencing of the hypervariable 16SrRNA gene has been introduced recently. The aim of this study is to investigate the suitability of gene sequencing using our selection of PCR primers and conditions for rapid and accurate bacterial identification in pharmaceutical industry quality control.DNA was extracted from overnight incubated colonies from 10 bacterial ATCC strains, which are common contaminants in the pharmaceutical industry. A region of bacterial 16SrRNA gene was analyzed by bidirectional DNA sequencing. Bacterial identification based on partial sequencing of the 16SrRNA gene is the appropriate method that could be used in the pharmaceutical industry after adequate validations. We have successfully identified all tested bacteria with more than 99 % similarity to the already published sequences.

Nutraceutical Properties

The benefit of carotenoids to human health is undeniable and consequently, their use for this purpose is growing rapidly. Additionally, the nutraceutical properties of carotenoids have attracted attention of the food industry, especially in a new market area, the ‘cosmeceuticals.’ Marine organisms (microalgae, seaweeds, animals, etc.) are a rich source of carotenoids, with optimal properties for industrial production and biotechnological manipulation. Consequently, several papers have reviewed the analysis, characterization, extraction and determination methods, biological functions and industrial applications. But, now, the bioaccessibility and bioactivity of marine carotenoids has not been focused of any review, although important achievements have been published. The specific and diverse characteristic of the marine matrix determines the bioavailability of carotenoids, some of them unique in the nature. Considering the importance of the bioavailability not just from the health and nutritional point of view but also to the food and pharmaceutical industry, we consider that the present review responds to an actual demand.

Amylase is an amylolytic enzyme used in food industry which is generally produced by Aspergillus spp. under solid state fermentation. The present study is concerned with the isolation, screening and selection of suitable strains of Aspergillus spp. and optimization of cultural conditions for the biosynthesis of amylase. Rice and wheat brans were used as substrates which are readily available inexpensive raw materials for amylase production. From 85 samples of rice and wheat grains, 55 colonies obtained on potato dextrose agar (PDA) were suspected to be Aspergillus oryzae and only 35 colonies possessed the morphological characteristics similar to that of A. oryzae indicating the isolates were most likely the strains of A. oryzae. Of all the fungal isolates of Aspergillus spps., Asp.31 gave maximum production of amylase (720.782 IUgds-1) in solid state fermentation media. This strain was selected as a parental strain for optimization for cultural conditions. The obtained data were analyzed using SPSS- 11.5 program. Of all the substrates (rice bran, wheat bran and their mixture), rice bran was the best for producing amylase of highest activity 611.614 IUgds-1.The highest enzyme activity of 698.749 IUgds-1 was observed at 50% initial moisture level of the substrate. The optimum temperature was 25°C for producing the crude amylase enzyme with amylase activity of 577.757 IUgds-1.
