Vacuum packaging and modified atmosphere packaging (MAP) are widely applied packaging methods for displaying refrigerated fish and fish products. This study evaluated the biochemical and microbiological quality of sliced goonch fish (Bagarius bagarius) by analysing different parameters under not sealed pack (control), vacuum pack, and MAP-1 (50% CO2 / 50% N2), and MAP-2 (50% CO2 / 50% O2) at three days interval in 15 days of refrigerated storage at 4±1°C. The total volatile base nitrogen (TVB-N), peroxide value (PV) and thiobarbituric acid reactive substances (TBARS) values of the samples in four packaging systems did not cross the acceptable limit in the entire storage time. The total viable count (TVC) progressively increased with time in all packaging systems. However, TVCs were significantly (p<0.05) lower on 9th and 12th storage day in all samples compared to the control sample. Based on the bacterial counts of 7 log CFU/g, the shelflife was determined at about 6, 10, 12, and 9 days for control, vacuum, MAP-1, and MAP2 sample, respectively. All treatments offered satisfactory results during the storage period, except for the control in terms of shelf life. However, MAP-1 with 50% CO2 and 50% N2 demonstrated the promising result for shelf life extension, which can be utilised by the retail superstores for displaying the fishes.

Quality And Shelf Life

The sensory and microbiological quality of sliced mushrooms (Agaricus bisporus L.) packaged in films of perforated and non-perforated PVC and stored at 3 and 9ºC, was studied. The carbon dioxide and oxygen content inside the packages, colour, weight loss, sensory attributes, mesophiles, Pseudomonas, Enterobacteriaceae, aerobic and anaerobic spore formers were determined. The atmosphere generated with the perforated PVC film was similar to that of air atmosphere at 3 or 9ºC. T.he non-perforated PVC film generated inside the packages CO2 : O2 concentrations of 3.4% : 8.1% at 3ºC and CO2 : O2 concentrations of 4.5% : 0.15% at 9ºC. Browning of mushrooms was lower at 3 than at 9ºC. The quality of sliced mushrooms packaged in perforated PVC and stored at 3ºC was adequate after 9 days. However, at 9ºC, the slice deformation and brown blotches incidence were severe after 9 days. The atmosphere generated with non-perforated PVC inhibited aerobic microorganism growth compared to mushrooms packaged in perforated PVC. At 3ºC, the shelf life of mushrooms packaged in non perforated PVC was around 13 days. However, the extremely low O2 atmospheres generated at 9ºC was accompanied by off-odours and growth of anaerobic spore formers, although the appearance of sliced mushrooms was acceptable.;

Objective. The study aimed to determine the physico-chemical and microbiological quality of ice blocks sold in selected wet markets located in the city of Manila. Methods. Twenty-eight samples were collected from three markets. Microbiological quality was analyzed in terms of the presence or absence of coliforms with E. coli as indicator organism. Physico-chemical quality was determined by measuring turbidity, apparent color, pH, iron, and residual chlorine. Measurements obtained were compared with the 2007 Philippine National Standards for Drinking Water (PNSDW). Results. Results showed that all samples tested positive for coliforms while 25 out of the 28 samples were positive for E. coli. Mean turbidity was 2.74 ± 3.68 NTU; for both apparent color and iron tests, all samples complied with the PNSDW standard limit set; mean pH was 6.15 ± 0.64; and mean residual chlorine was 0.06 ± 0.02 mg/L. Average values of apparent color and iron comply with the PNSDW standards. Six out of 28 samples had turbidity values exceeding the standards. All samples were found to have residual chlorine levels below the standards. Conclusion. Ice in markets do not comply with key 2007 PNSDW standards and findings warrant strict compliance of ice quality from manufacturers to the point of distribution to protect consumer health.

Storage temperature and duration plays an important role in meat processing. Observations in poultry processing plants have shown a serious deviation in storage condition compared to the recommended procedures. Furthermore, there is still a paucity of evidence on the effects of storage temperature and duration on meat quality and microbial population. The aim of this study was to determine the effects of different temperature and duration during storage on physico-chemical properties and microbiological quality of broiler chicken Pectoralis major muscle. Eighty birds were slaughtered and processed, following which the packed boneless breast (PBB) (each bird was to provide two breast muscle samples; left breast and right breast) was divided into four groups, each consisted of 40 PBB. Each group was subsequently assigned to storage either at 4 °C, −10 °C, −18 °C or −40 °C, for 24 h before 20 PBB samples from each group were transported to the respective laboratory for meat quality and microbiological analysis. The remaining 20 PBB from each storage temperature were stored for 72 h before being transported for analysis. Results have shown significant increases in drip loss and cooking loss as the storage temperature decreases. Similarly, storage duration significantly affected cooking loss, of which, samples stored for 72 h exhibited higher cooking loss compared to those stored for 24 h. For color, significant differences were only observed in lightness (L*) and redness (a*) values. Longer duration of storage had significantly improved tenderness whereby, samples that have been stored for a shorter duration presented higher pH values. Populations of coliform and Salmonella decreased significantly with decreasing temperature and increasing storage duration.

The dairy industry strives to produce high quality products with high nutritional value as well as to meet the legal standards for longer shelf life. However, these goals are made unfeasible by the poor quality of raw milk produced in some regions of Brazil. Others Brazilian dairy regions, however, already succeed in producing milk with low microbial counts, such as the municipality of Castro, Paraná state, designated as the ‘Brazilian dairy capital’. In order to evaluate the effect of raw milk quality on microbial counts during the shelf life of pasteurized milk, samples were collected from two dairy regions of Paraná: the northern and Castro region, characterized by milk production with high and low microbiological counts, respectively. Samples were experimentally pasteurized and the total microorganism counts were analyzed for 18 days at 7°C, using the Brazilian standard microbiological count limit for pasteurized milk (8 x 104 CFU/mL) as the end of the shelf life. Low microbiological counts in raw milk (Castro) resulted in significantly lower counts shortly after pasteurization and over the entire shelf life, meeting the pasteurized milk standard for 18 days. The temporal evolution in the counts over 18 days for the milks of high and low microbiological count was similar; however, the disparity between the absolute counts between the regions was significant (p < 0.05). Of the milk samples from northern Paraná, four (44.4%) already had counts higher than that of the legislative limit for pasteurized milk immediately after pasteurization. The others (five) reached the maximum microbiological count limit for pasteurized milk on the 6th day after pasteurization. In contrast, the milk from the Castro region remained below the limit throughout the analysis period. Thus, it can be stated that the microbiological quality of raw milk is directly related to the initial count of microorganisms after pasteurization, and that pasteurized milk produced from raw milk with low microbiological counts complies with the Brazilian legislation for 18 days following thermal processing.
