This article looked at the quantity and storage time of attiéké produced and sold in the town of Daloa. It also examines the microbiological characteristics of attiéké-femme and attiéké-garba from this locality during storage. The study was carried out on the one hand through a field survey carried out on the producers and sellers. On the other hand, a sample was taken from 10 sellers of attiéké-garba and 10 sellers of attiéké-woman. The study found that the women producers sell 87% of their production in the city of Daloa and export 13%. In addition, attiéké can be kept for 2 days at the producers and beyond 2 days at the sellers before their stock runs out. Therefore, a weekly production of more than 200 kg for the majority of the producers is observed. Microbiological analyses showed high levels of germs (MAG: 6.106 CFU/g; Yeasts and moulds: 2.7.106 CFU/g) for attiéké-women and (2.106 CFU/g of GAM and 1.6.103 CFU/g of Yeasts and moulds) for attiéké-garba. Total coliforms and faecal coliforms were only found in attiéké-women. No salmonella was observed. In view of the results, it should be noted that female attiéké is the most contaminated type of attiéké.

The aim of this study is to evaluate the hygienic quality of the dishes cooked and sold by the women traders in the town of Korhogo. The study was carried out with 45 restaurants in the town of Korhogo. It consisted on the one hand, a survey based on the Ishikawa diagram in order to assess the hygienic conditions, and on the other hand of microbiological analyses of the ready-to-serve meals. A total of 90 samples were taken, including 2 dishes per restaurant, respectively consisting of one hot and one cold dish. Generally, results showed that hygienic conditions were unsatisfactory based on the utilized guidelines. From a microbiological point of view, the meal samples were 75.2% satisfactory, 7.6% acceptable and 17.2% unsatisfactory. In view of these results, it appears essential to improve hygiene conditions by greater involvement of the official services involved in training these traders and monitoring compliance with good hygiene practices and the establishment of a program of cleaning and disinfection of premises and equipment.

The objective of this research was to determine physicochemical changes and microbiological quality of the different packaged meatball samples. Meatball samples in polystyrene tray were closed with polyethylene film (PS packs), vacuumed and modified atmosphere packaged, (MAP) (65% N2, 35% CO2), and held under refrigerated display (4 °C) for 8, 16 and 16 days for PS packs, vacuum and MAP, respectively. Microbial load, free fatty acids and thiobarbituric acid values of the samples tended to increase with storage time. Bacteria counts of the raw meatball samples increased 2 log cycles at the end of storage compared with initial values. Meatball samples can be stored without any microbiological problem for 7 days at 4 °C. Results from this study suggested that shelf-life assigned to modified-MAP and vacuum-packed meatballs may be appropriate. Meatball samples underwent physical deformation when they were packed before vacuum process. With these negative factors considered, MAP is superior to other two packs methods.

This study aims to determine the effect of giving levels of turmeric flour and storage time on microbiological quality, sensory quality and chemical quality of mackerel fish sausages. The method used in this research is descriptive research used to observe the total number of bacterial colonies and molds, while experimental research using Factorial randomized block design (RBD) for analyzing sensory tests. Completely Randomized Design (CRD) factorial pattern for analyzing water content and pH tests. The results showed the administration of turmeric flour can inhibit bacteria and mold for 12 hours. Sensory testing showed an interaction between the level of turmeric flour treatment and storage time. Chemical testing shows the storage time can cause fluctuations in water content. The pH test shows the level of turmeric flour can increase the pH value, and the pH value will decrease during storage. The conclusion of the study is that the level of turmeric flour and storage time affect the quality of sausage microbes. The interaction between the level of turmeric flour and the length of storage has an influence on the taste and texture of fish sausages during storage by inhibiting the growth of microbes so as to maintain quality degradation. levels of turmeric flour and storage duration affect the chemical quality of sausages

The present study had as objective to assess the microbiological quality and profile of some braised products and their accompanying soups sold in the city of Bangangte (Cameroon) and evaluate the antibiotic susceptibility of selected pathogens isolated in these products. An investigation was conducted in three locations in city of Bangangte in order to assess the environment and working conditions as well as the respect of good hygiene practices. Then, samples of braised fish (05) and its soups (05), and braised chicken (05) and its soups (05) were collected from six vendors in each location. The samples (360) were submitted to microbiological analyses and the isolates were identified at species level using API gallery. The susceptibility of the isolates to 14 antibiotics were tested. The 72 participants involved in this study declared having knowledge on hygiene despite the fact that, most of them had no formal education and do not apply good hygiene practices. Microbiological analyses revealed the poor quality of all the samples of braised products. Fecal coliforms and staphylococci counts higher than the values recommended by norms demonstrated the non-respect of good hygiene and manufacturing practices during the braising activity. The 169 strains isolated from these products belonged to 12 different species: Enterobacter gergoviae, Enterobacter spp., Morganella morganiae, Yersinia enterolitica, Yersinia frederiksenii, Staphylococcus aureus, Staphylococcus epidermitidis, Staphylococcus spp., Clostridium spp., Klebsiella pneumoniae, Enterobacter aerogene, and Proteus mirabilis. Strains which could be considered as marker of braised fish sold in the city of Bangangte were Yersinia enterolitica, Staphylococcus aureus and Klebsiella pneumonia while for braised chicken, they were Yersinia enterolitica, Staphylococcus aureus and Proteus mirabilis. The antibiotic susceptibility test performed on these pathogens revealed that they were resistant with 93.75% having multiple antibiotic resistance index values greater than 0.2. We conclude that the microbiological quality of braised products is poor and we suggest to producers to applicate the good hygiene practices. For breeders, we suggest respecting withdrawal periods and the better use of antibiotics.

AbstractThe paper presents the impact of the initial processing, cultivar, and storage time on the physical and chemical quality of freeze-dried sweet pepper crisps. Sweet pepper after initial washing and crushing was subjected to further four combinations of the initial processing. The first combination included freezing, the second one blanching in 98°C and 2-minutes time, the third one -dehydration in 2% solution of ascorbic acid and the fourth one - dehydration in the 2% solution of sodium chlo-ride. Both types of dehydration were carried out in 70°C for 20 minutes with a 1:4 participation of raw material to osmotic solution. Blanched and dehydrated raw materials were subjected to freezing in -18°C for 24 hours. After the completed process of freezing, the samples were moved to a freezer-drier and were dried by sublimation in -18°C and the reduced pressure of 63 Pa. The research that was carried out proved that the microbiological quality of the obtained sweet pepper lyophilizes was significantly affected by the cultivar, treatment type and storage time. These factors significantly diversified the number of micro-organisms in sweet pepper crisps. No initial processing before sublimation drying caused a considerably average increase of the number of psychrophile and mesophilic bacteria in crisps from both sweet pepper cultivars. A considerable reduction of their total number took place during blanching and dehydration in the ascorbic acid solution and sodium chloride solution. Additionally, along with the storage time, reduction of the total number of psychrophilic, mesophilic bacteria, fungi and yeasts was reported.

The effects of potato variety (Van Gogh, Bintje and Fambo), washing with browning prevention Chemicals in place of sodium bisulfite, percentages of CO2, O2, and N2 in the package headspace, and storage time (1,4, and 7 days) on the sensory and microbiological quality of potato slices were examined. Citric acid and ascorbic acid (at 0.1% each and at 0.5% each) were used as browning prevention Chemicals. In the packaging atmosphere the percentage of N2 was 75 or 80%, the percentage of O2 was 5 or 0%, and the percentage of CO2 was 20% at the beginning of storage. Packed potato slices were stored in the dark at 5°C. Darkening was the most important factor limiting the sensory quality of raw potato slices. Darkening occurred quickly with Fambo slices; it seems that Fambo is not a suitable potato variety if slices are to be stored. Water-washed and cooked Van Gogh slices were still acceptable for retailing after a storage period of 7 days. After 7 days of storage the best sensory quality of both raw and cooked Bintje slices was obtained with washing Solutions containing 0.1 to 0.5% citric and ascorhic acids and with the gas mixture containing 20% CO2 and 80% N2. The number of microorganisms was higher in samples stored in the atmosphere containing 5% O2 than samples stored in the atmosphere containing 0% O2. Washing of potato slices with browning prevention Chemicals decreased the number of microorganisms compared to potato slices not washed or potato slices washed with water after 7 days of storage.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

The effect of different composite coatings on quality of semi-moist apricot cubes mixed with cornflakes was investigated during 180 days of storage. The apricot cubes were osmotically dehydrated (OD) and coated before hot-air drying (HAD) at 60 °C. Chitosan-bees wax (CBW) and whey protein isolate-bees wax-oleic acid (WPI-BW-OA) coatings were applied after HAD and the samples were added to cornflakes. Application of OD and pectin-ascorbic acid (Pec-AA) coating (prior to HAD) and WPI-BW-OA coating (after HAD) led to significant retention of total phenol compounds, β-carotene and antioxidant activity in apricot cubes compared to uncoated and CBW-coated samples. WPI-BW-OA-coated samples gave significantly higher L* values (lighter color) and b* values (more creamy or yellowish color) and lower a* values (less reddish color) and browning values than control followed by CBW-coated apricots at any time of storage (p < 0.05). The rate of apricot moisture loss and cornflakes moisture gain was higher in uncoated apricot cubes, followed by CBW- and WPI-BW-OA-coated samples. Application of WPI-BW-OA coating was effective in retaining the crispness measured by lower firmness (Fmax) values in cornflakes upon storage. Based on the obtained results, WPI-BW-OA coating allowed effectively preserving the quality characteristics of semi-moist apricot cubes and cornflakes components in the mixed state.
