To assess the quality of sweetened condensed milk of Bangladesh four different brands of sweetened condensed milk were selected viz. Danish, Fresh milk, Star ship and Goalini. Twenty samples were analyzed for physical (organoleptic), chemical and microbiological qualities. From the physical test it was observed that all samples were in good grade i.e. fresh, free from odour, viscous and smooth, rich cream to yellow in colour and very sweet in taste. The average physical score was 88.05±7.631. Sweetened condensed milk had a titrable acidity of 0.135 to 0.180 %; fat 6.80 to 8.0 %; protein 6.51 to 7.96 %; ash 1.50 to 1.83 %; carbohydrate 53.74 to 55.62 % and total solids (TS) 69.98 to 73.15 %. The total viable count was in the range of 10x102 to 20x102 CUF/g; no coliform bacteria were found. The results of acidity percentage, fat content, organoleptic tests and microbiological tests indicated that there was no variation among different brands of sweetened condensed milk. But, when other chemical parameters (protein, ash, carbohydrate and total solids) were considered then Star ship was found to be better than that of Danish, Goalini and Fresh milk. Bangladesh J. Sci.

The study was undertaken to evaluate the quality of Dahi available in Sylhet Metropolitan City. Dahi samples from five different Sweetmeat Shops namely Fulkoli, Banaful, Mohanlal, Modhuban and Shad were collected and analyzed. Significant difference in chemical (protein, fat, total solids, ash, acidity and pH) and microbiological status was found among different Dahi samples. Of the five Dahi Brands examined, Fulkoli Brand Dhai had the highest protein content (4.58 ± 0.24) and Shad Brand Dahi had the lowest protein content (4.01 ± 0.17). Fat content was highest in Fulkoli Brand (4.02 ± 0.13) and lowest in Shad Brand (2.10 ± 0.21). The highest total solids content was found in Dahi of Shad Brand (38.00 ± 2.23) and lowest total solids content was found in Banaful Brand Dahi (32.02 ±1.50). Highest Total Viable Count (log cfu/ml.) was recorded in the Dahi of Shad Brand (5.92±0.09) and lowest Total Viable Count was recorded in Mohanlal Brand Dahi (5.84±0.06). Coliform bacteria, Yeast and Mould were present in all the samples. From this experiment, it was found that Fulkoli Brand Dahi was the best in quality . Dahi of Banaful and Mohanlal were in 2nd and 3rd position in quality.

This experiment was conducted to evaluate the quality of existing ultra-high temperature (UHT) treated milk available in two selected town markets of Bangladesh. A total of 27 UHT milk samples from three different brands–Pran Dairy (A), Aarong Dairy (B) and Farm Fresh (C) were collected from local markets at Mymensingh and Gazipur districts during the period of 1stSeptember to 29th November, 2014. Parameters studied in this experiment were organoleptic (flavour, consistency, colour and appearance), physic-chemical (specific gravity, acidity, total solids, solids-not-fat, fat, protein, lactose, and ash) and microbiological (Total Viable Count and Coliform Count). All the samples were similar in respect of color, flavor, taste and texture, and no significant difference was observed. However, significant differences were revealed (p<0.05) in case of specific gravity, acidity, total solids, solids-not-fat, and protein content. On the other hand, insignificant differences were found (p>0.05) in case of fat, lactose, and ash content. Total Viable Count and Coliform count were found to be nil in all the milk samples. Milk samples of Farm Fresh UHT milk were superior to other brands of UHT Milk in terms of contents of total solids (119.23±0.57 g/kg),fat (34.97±0.35g/kg), lactose (43.23±0.51g/kg), and ash (7.00±0.26g/kg). Though there were some fluctuations in all the parameters studied, all the milk samples conformed to the standard values for UHT milk, and in general all of the UHT milk samples studied in this experiment was of good quality.Bang.

The aim of this work was to develop a methodology to calculate the cooling curve for the sweetened condensed milk with added whey powder production and to assess the cooling regime effect on the distribution of lactose crystals’ size and their microstructure. It is proposed to use a two-stage cooling curve. At the first stage, the cooling is carried out at a high speed, and at the second with a speed that varies depending on the rate of lactose crystallization. Electron microscopic studies have confirmed the cooling regime effect on the crystals’ microstructure. The practical use of the developed regime showed that the two-stage cooling regime allows to reduce the size of lactose crystals (P < 0.05) and improve the quality of the finished product.

Out of 100 raw milk samples collected from one hundred cows infected with mastitis, thirty three isolates of different types of pathogenic bacteria were isolated using different types of selective media.  On the basis of traditional bacteriological tests, these isolates were identified as the following: 13 isolates of Staphylococcus aureus, 9 isolates of B-haemolytic Streptococci, 6 isolates of Coliform bacteria, 4 isolates of Corynebacterium pyogenes, and only one isolate Bacillus cereus.  In addition to these isolates, a number of non-pathogenic bacteria were recovered during the isolation and they were considered as contaminants of milk such as S. epidermidis, C. bovis and B. subtilus.  The total number of living bacteria present in milk samples was measured and it was ranged from (1400 to 1800) bact./ml.  The isolates of pathogenic bacteria were tested for their sensitivity to different types of antibiotics and the results were: 100% of these isolates were sensitive to Gentamycin and Tetracycline, 11 (84.6%) isolates of S. aureus, 6(66.2%) isolates of B-hacmolytic Streptococci , 4(66.2%) isolates of Coliform bacteria and 3(75%)  es of C. pyogenes were sensitive to Ampicillin, Penicillin, Erythromycin and Cepholexin. While Bacillus cereus isolate was resistant to all these antibiotics.  As a result of this work, generally the bacteriological quality of this milk is acceptable due to the low number of viable count of bacteria in   milk and the isolates showed high level of sensitivity to the antibiotics used in this study.

A study was carried out to investigate microbiological quality of ice cream available in Chittagong area of Bangladesh during June to July 2008. Each brand of ice cream was collected from retail stores of Chittagong City. Standard plate count (SPC) and coliform count were done for bacteriological assessment of the ice cream samples. The average SPC count of Kwality, Igloo and Sub Zero ice cream samples were 2 x 103, 3 x 103 and 4 x 103 cfu/g respectively. Coliform organisms were detected in all the ice cream samples and the average coliform counts of the ice cream samples from Kwality, Igloo and Sub Zero were 12, 18 and 42 cfu/g respectively. Coliform bacteria exceeded standard limits, which can cause serious health problems.

Freshly prepared and pasteurized fruit juices sold by vendors in local market of Rawalpindi city from 10 locations were analyzed for the microbiological quality. Total viable count (TVC), total coliform, faecal coliform, molds and the presence of pathogenic microorganisms such as E. coli, Pseudomonas, Staphylococcus aureus, Salmonella, and fungi like Aspergillus, Pencillum, Rhizopus were determined .In open fruit juices available in city were highly contaminated with bacteria and fungi. E. coli, Salmonella, Staphylococcus, and Pseudomonas were isolated with different frequency. Aspergillus, Pencillum and Rhizopus were also found in juices especially Aspergillus was with high percentages. The pasteurized juices have less contamination as compared to the fresh juices samples. The number and type of microorganisms recovered from the freshly squeezed fruit juices made them unsafe for drinking. The results of this study demonstrate the unhygienic quality of popular types of market vended freshly squeezed fruit juices and their risk to the consumers.
