Abstract The change of the quality of wheat milling products was investigated in our work. We analysed different types of wheat grists that are used in household (BL-55, BL-196, BFF-55 and AD). The grists were stored in three type of packages (paper bag, transparent PE bag, and woven PP bag) and in two different places (bright/warm and dark/cool place) for 6 months. The titre and colour characteristics of samples were measured monthly. Colour measurements were performed with a Hunter MiniScan colour-measuring instrument. The CIELab colour system was used for colour characterization. The values of titre were analysed using ANOVA. The type of package did not have significant influence on the titre. In the case of the BL-55, BL-196, and BFF-55 type of ours, the storage conditions had a significant effect on titre: it was smaller for samples that were stored in the dark/cool place. The value of titre rose significantly during storage for all samples. To determine the change of colour, we calculated the ΔE*ab colour differences between colour coordinates measured at the beginning and during storage. The colour of the BL-55 and BL-196 our samples did not change perceptibly. The variation of colour of the BFF-55 and AD type of ours was imperceptible for samples stored in the dark/cool place. The changing of the colour was well perceptible in the case of samples stored in the bright/warm place using paper bag or PP bag.

Abstract The use of natural food colours is preferred to that of arti­ficial dyestuffs for modern alimentary purposes. Paprika is a spice plant grown and consumed in considerable quantities worldwide and also used as a natural food colour, so the colouring power of powders is very important. The colour of paprika powder is highly relevant too because the consumer concludes its colouring power based on its colour. The colouring power of paprika powders is directly determined by the quality and quantity of the colouring agent of paprika. The paprika oleoresin, that is an oil soluble extract from the fruits of Capsicum Annum Linn or Capsicum Frutescens, is suitable to raise the colour agent content of paprika powders. We investigated how the colour and the characteristics of paprika powder samples with added oleoresin change in the course of storage. The colour agent content of 7 different quality powders was increased with 7-75% using oleoresin. The initial colour agent content of samples changed between 41 and 169 ASTA units. The powders were made from Chinese, Peruvian, and Hungarian paprika. Colour measurements were performed with a HunterLab MiniScan colour-measuring instrument. The CIELab colour system was used for colour characterization. The colour agent content and the colour coordinates of samples were measured throughout 9 months. The decrease of colour agent con­tent varied between 22 and 51 percent, while the average reduction was 33 percent. The quantity of added oleoresin did not influence the colour agent content decrease significantly. The values of colour difference changed between 2 and 4.5 units. The initial paprika powder influenced the variation significantly, but the quantity of added oleoresin did not have a significant effect.

Aims: Fish is a product more and more consumed in Burkina Faso, especially in Ouagadougou. Poor sale and storage conditions can impact on the hygienic quality of fish. The objective of this study was to identify the contamination risks due to the sale and storage conditions of smoked, dried and fresh fishes. Study Design: A descriptive design was used to identify the different types and origins of fish on the markets in Ouagadougou and the practices and conditions of sale that could be sources of chemical and microbiological contamination. Place and Duration of Study: Relevant data was collated in Ouagadougou (Burkina Faso) from February 2019 to July 2019. Methodology: A survey was conducted among traders of dried and smoked fish from 50 markets and major sales sites in Ouagadougou. Data collection was done using a questionnaire developed with Sphinx Plus2 software. Results: The results indicated a higher proportion of men (75%) than women (25%) with an age between 21 and 45 years old were participated in fish trade. The fish encountered in the markets of Ouagadougou come from Sourou, Kompienga and Bagré, as well as from external suppliers such as Côte d'Ivoire, Mali and Senegal. The different types of fish sold were dried or smoked carp (36.67%), smoked catfish (23.33%), dried Nanani or Djêdjê wala (concorde) (13.33%), smoked Macharon (10%), smoked Racok (10%) and smoked eels or Roolgo in mooré (local language) (6.67%). The types of fish most purchased by consumers, in order, were: Carp, Catfish, Macharon, Nanani. In addition, the study detected risks of contamination of the fish, namely: exposure material consisting of tables and baskets, conservation at room temperature, storage period of 10 to 30 days, no training in hygiene, fish served with bare hands, exposed to dust and stray animals. Conclusion: In sum, the study revealed some characteristics of the fish industry in Ouagadougou and also risks of contamination of fish sold on the markets.

Background: Ajwain is used as an antioxidant, as preservative and also valued for its medicinal properties. Ajwain seeds undergo deterioration during storage due to various microorganisms and leads to degradation of quality in terms of discolorations and altering the biochemical constituents. Hence, the effect of different types of storage conditions on quality of ajwain seeds was investigated. Methods: To assess the effect of storage in four different types of containers viz. Plastic jars (PJ) of make Pearl Pet, tin containers (TC), gunny bags (GB) and plastic lined gunny bags (PLBG) were used. The duration of storage was one year. External environmental conditions, i.e. temperature and relative humidity were recorded quarterly. To study the effect of different storage conditions on quality: (i) Seed quality assessment according to Agmark grade specifications (ii) incidence of mycoflora and (iii) effect on biochemical constituents viz. moisture, crude protein, crude fat, crude fiber, ash, carbohydrates, total soluble sugars, iron, total phenols and volatile oil contents were studied. Initial readings served as control for the experiment. Results: Irrespective of storage conditions, a sharp increase in deterioration was noted in stored samples of ajwain with respect to presence of shrivelled, damaged, discolored and weevilled seeds after 3 months of storage. This shifted the samples from good to substandard grade. Maximum deterioration was noted after 12 months. The incidence of mycoflora was found maximum in samples stored in tin containers and gunny bags followed by plastic lined gunny bags and plastic Jars. A decline in moisture, crude fiber, carbohydrates, total soluble sugars, iron and volatile oil contents and an increase in crude fat and ash contents were observed after 12 months of storage, irrespective of storage containers. Plastic jars were found to be the best of all containers studied for storage purpose.

The utilization of the ChemScan® RDI was tested for different types of water concentrates. Concentrates were prepared by cartridge filtration or flocculation, and analysed either without purification, or after Immunomagnetic separation (IMS) or flotation on percoll-sucrose gradients. Theenumeration of the oocysts was subsequently performed using the ChemScan® RDI Cryptosporidium application. Enumeration by direct microscopic observation of the entire surface of the membrane was carried out as a control, and recoveries were calculated as a ratio between the ChemScan® RDI result and the result obtained with direct microscopic enumeration. The Chemscan enumeration technique proved reliable, with recoveries yielding close to 100% in most cases (average 125%, range from 86 to 467%) for all the concentration/purification techniques tested. The quality of the antibodies was shown to be critical, with antibodies from some suppliers yielding recoveries a low as 10% in some cases. This difficulty could, however, be overcome by the utilization of the antibody provided by Chemunex. These data conclusively prove that laser scanning cytometry, which greatly facilitates the microscopic enumeration of Cryptosporidium oocysts from water samples and decreases the time of observation by four to six times, can be successfully applied to water concentrates prepared from a variety of concentration/purification techniques.
