Storage stability of processed chicken meat bullets (CMB) packaged under different packaging conditions in supplementation with composite antimicrobial biodegradable (CAB) films impregnated with 0.5% (v/v) cinnamaldehyde, a natural antimicrobial, was evaluated. Different treatments such as aerobic (aerobic packaged product, CAB-coated product and aerobic packaging), modified atmosphere packaging (MAP; MAP 50 : 50; CO2 and N2, F-MAP; CAB-coated product and MAP) and vacuum (VAC; vacuum packaged, F-VAC; CAB-coated product and vacuum) are assessed for various physico-chemical (pH, thiobarbituric acid reactive substances number, peroxide value and free fatty acids), microbiological (standard plate count, psychrophiles, coliforms, yeast and moulds, Staphylococci sp.) and sensory quality characteristics at 7-day intervals throughout the storage period of 35 days under refrigerated (4 ± 1°C) conditions. The CMB coated with CAB films under MAP (F-MAP) conditions had significantly (P < 0.05) better value for water activity, thiobarbituric acid reactive substances number, peroxide value and free fatty acids throughout the storage in comparison to the Control (MAP). Standard plate count was significantly (P < 0.05) lower for F-MAP than all other treatments. Staphylococci sp., coliforms, Salmonellae sp., yeast and mould, and psychrophiles were completely absent in CAB-coated products throughout the storage period. All the CAB products had better (P < 0.05) sensory attributes than their respective Controls during storage. Results concluded that the CMB coated in developed CAB films have a storage life of more than 35 days under MAP conditions under refrigerated (4 ± 1°C) conditions with the acceptable physico-chemical, microbiological and sensory quality attributes.

Storage stability of raw chevon (goat meat) chunks wrapped in preformed, bioactive, biodegradable films based on composite starch–chitosan and impregnated with nisin (60 000 IU/g; T-1) and cinnamaldehyde (0.5% v/v; T-2) was evaluated relative to unwrapped product (control) under aerobic refrigeration (4°C ± 1°C) conditions for 10 days. Samples were taken on Days 1, 4, 7 and 10 to assess various physicochemical, microbiological and sensory quality parameters. Water activity and pH of raw chevon chunks followed a decreasing trend during storage under all packaging conditions; the rate of decrease of water activity was higher (P < 0.05) in the control than in bio-packaged products. Values of thiobarbituric acid reactive substances increased throughout storage and were lowest in T-2 and highest in the control. Extract release volume decreased throughout storage under all packaging conditions; however, it was higher (P < 0.05) in bio-packaged products than the control. Microbial quality was better in bio-packaged products than the control throughout storage. Standard plate count was 2.09 log10 cycles lower in T-2 than the control, and coliform count was lower by log10 2.31 cfu/g in T-2 and log10 1.88 in T-1 than the control on Day 7 of storage. Staphylococcus counts were lower (P < 0.05) in bioactive-packaged products than the control throughout the storage period. Sensory quality attributes colour, odour, texture and overall acceptability were better maintained in bio-packaged products than the control during storage, and maximum scores were awarded to T-2. The results indicate that starch–chitosan composite films impregnated with cinnamaldehyde can be used for the packaging of raw goat meat and successfully extend storage life by inhibiting the colour, oxidative and microbial deteriorative changes under refrigeration.

During a 5-month period, 200 raw milk samples were collected from two Louisiana milk plants. Standard Plate Count (SPC), Psychrotrophic Bacteria Count (PBC), and Proteolytic Count (PC) of each sample were initially determined, then monitored daily during a 5-d storage period at 2.2°C. As hypothesized, all bacterial counts increased during the storage period. The magnitude of the increase in bacterial numbers during storage was further investigated by dividing the milk samples into bacteriologically acceptable and unacceptable groups based on SPC or Preliminary Incubation (PI) count. An SPC of 1.0 × 105/ml and PI counts of 1.0 × 105/ml, 1.5 × 105/ml, 2.3 × 105/ml, and 3.0 × 105/ml were used to repeatedly dichotomize the 200 raw milk samples into two groups. Median SPC, PBC, and PC for each acceptable and unacceptable group were then calculated. Dichotomization based on PI counts yielded acceptable sample groups having consistently lower bacterial counts during storage than did the acceptable sample group, which resulted from the dichotomization based on a SPC of 1.0 × 105/ml. The results of this study indicated that the PI count is of considerable value for raw milk quality control.

To determine the effect of delayed heading on shrimp quality, shrimp were stored on ice with and without heads for 10 days. Some shrimp were delay-headed after 5 days and returned to ice for the remainder of the storage period. Microbiological studies were conducted at 0, 5 and 10 days of storage. Total aerobic plate counts were done using Standard Plate Count agar with an added 0.5% NaCl. Incubation was at 20 C for 5 days. Analyses indicated similar counts on shrimp tails stored with or without heads and those delayed-headed. Counts ranged from 2.4 × 106 bacteria/gram at 0 day to 1.6 × 109 bacteria/gram on the 10th day. Identification of the flora present revealed that the same major groups of organisms predominated on shrimp tails subjected to the different storage treatments and the head did not alter development of the usual flora. Flavobacterium, Pseudomonas, Planococcus, Moraxella and the Vibrio/Aeromonas group were the major genera encountered. A shift in bacterial populations was observed during storage. Flavobacterium species predominated during the first 5 days of storage; however, after the fifth day Pseudomonas species predominated. Sensory panel data revealed no differences in acceptability between shrimp tails stored with or without heads and those delay-headed.

Effects Of Irradiation On

After irradiation of chickens to a dose of 2.5 kGy, the decrease in the standard plate count (SPC) was similar in air and in vacuum-packaged chickens. During storage at 4°C for 15 d, the SPC increased progressively in both types of packaged chickens. At the end of the storage period, the SPC was higher in air-packaged chicken than in vacuum-packaged chickens. In irradiated chickens, Listeria monocytogenes was only recovered from the vacuum-packaged chickens after 7 d cold storage. In unirradiated chickens, L. monocytogenes proliferated similarly in both air- and vacuum-packaged chickens.

AbstractThe objective of this present study was to investigate the potentiality of prebiotics (mannan oligosaccharides-MOS and fructo-oligosaccharides-FOS) in replacement of antibiotic growth promoter and their relationship with physico-chemical indices, antioxidant and oxidative stability and carcass traits of broiler chickens meat. Accordingly, 240 day-old broiler chicks of uniform body weight divided in 6 treatment groups with 5 replicate each (5 × 6 = 30) having 8 birds in each replicate. Six corn based dietary treatments were formulated viz. T1 (control diet), T2 (T1 + Bacitracin methylene di-salicylate @ 0.002%), T3 (T1 + 0.1% MOS), T4 (T1 + 0.2% MOS), T5 (T1 + 0.1% FOS), and T6 (T1 + 0.2% FOS). Significant (p < 0.05) increase in cut up part yields (%) and reduction in cholesterol and fat content in T4 (0.2% MOS) group. The water holding capacity (WHC) and extract release volume (ERV) were increase (p < 0.05) in 0.1 or 0.2% MOS supplemented group. DPPH (1, 1-diphenyl-2-picrylhydrazy) was higher (p < 0.05) and lipid oxidation (free fatty acid and thio-barbituric acid reactive substances) was lower (p < 0.05) in T4 group. The standard plate count (SPC), staphylococcus and coliform counts were decreased (p < 0.05) in T3 or T4 group. Thus, it can be concluded that mannan oligosaccharides (MOS) may be incorporated at 0.2% level in diet for improved physico-chemical indices, antioxidant and oxidative stability and carcass characteristics of broiler chickens meat and it may be suitable replacer of antibiotic growth promoter.

The experiment was carried out to prepare mustard ilish at the laboratory and observe the effects ofpackaging on the quality parameters of the product at room temperature (28°C to 32°C). Biochemical andmicrobiological changes in mustard ilish prepared from Hilsa shad (Tanualosa ilisha) were determined. It wasobserved that percent moisture, protein, lipid, ash content and pH value in mustard ilish decreased afterpreparation of the product than those values obtained for raw fish. In quality parameters study, at roomtemperature (28°C to 32°C), percent moisture, and ash contents increased throughout the storage period, butprotein and lipid contents decreased. The TVB-N, peroxide value and standard plate count (SPC) of bacteriaincreased with the progress of storage time but the rate of increment was comparatively slower in sealed andvacuum sealed packs than the rate observed for non-sealed pack. Therefore, on the basis of above mentionedpoints, the present study could be concluded as-though mustard ilish remain in acceptable condition for ashort time at room temperature (28°C to 32°C) but packaging has some effect on the extension of shelf life ofthe product.

To simulate conditions encountered in automobiles during warm weather in Florida, half-gallon cartons of milk, after tempering at 39 F, were exposed to 120 F for 0, 30, 60 or 90 min, after which milks were 39, 64, 78, and 91 F, respectively. All samples were then held at 39 F throughout the remainder of the study. The standard plate count was significantly higher on samples exposed to 120 F for 60–90 min than on those exposed for the shorter time. A taste panel detected flavor differences among samples of milk receiving the different heat exposures. The shelf-life of fluid milk was determined by the number of bacteria present in the sample at the commencement of the storage period, the length of the lag phase of growth, the rate of bacterial growth at the storage temperature used, and finally the type of microorganism present. If milk is to be exposed to high temperature in an automobile for more than 30 min, it should be held in an insulated container until it can be placed in the home refrigerator.

The objective of the present study was to evaluate the quality of refrigerated raw milk produced by 912 farmers in the Western part of Santa Catarina State, Brazil. The parameters analyzed were fat, protein, lactose, solids nonfat (SNF) content, standard plate count (SPC) and somatic cell count (SCC). A comparative analysis study with data from 2009 and 2010 was also conducted, which has shown that SCC influenced on the physico-chemical results. It was also observed that in 2010 the values for SCC were higher than in 2009, out of the limits recommended by the legislation until 2011. The SPC values were well above the maximum level accepted, indicating high contamination of milk with aerobic mesophilic microorganisms. The data collected indicated that only 4.9% of the producers sampled in 2009 and 8.1% in 2010 were in compliance with the standards enforced by a new legislation of January 2012. There was also increase on the milk fat content as SCC increased, which was not observed with other milk components. Lactose had a gradual reduction as SCC increased. On the other hand, SNF content did not correlate with SCC variance. These results demonstrate the urgent need of improvement in milk production and better technical orientation of milk producing properties to reach higher quality standards in Santa Catarina.

The aim of this study is to use of karkede (Hibiscus sabdariffa L.) byproduct as raw material to make ketchup instead of tomato. Ketchup is making of various pulps, but the best type made from tomatoes. Roselle having adequate amounts of macro and micro elements, and it is rich in source of anthocyanine. The ketchup made from pulped of waste of soaked karkede, and homogenized with starch, salt, sugar, ginger (Zingiber officinale), kusbara (Coriandrum sativum) and gum Arabic. Then processed and filled in glass bottles and stored at two different temperatures, ambient and refrigeration. The total solids, total soluble solids, pH, ash, total titratable acidity and vitamin C of ketchup were determined. As well as, total sugars, reducing sugars, colour density, and sodium chloride percentage were evaluated. The sensory quality of developed product was determined immediately and after processing, which included colour, taste, odour, consistency and overall acceptability. The suitability during storage included microbial growth, physico-chemical properties and sensory quality. The karkede ketchup was found free of contaminants throughout storage period at both storage temperatures. Physico-chemical properties were found to be significantly differences at p?0.05 level during storage. There were no differences between karkade ketchup and market tomato ketchup concerning odour, taste, odour, consistency and overall acceptability. These results are encouraging for use of roselle cycle as a raw material to make acceptable karkade ketchup.
