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.

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.

This study evaluates the effects of gelatin coating enriched with ethanolic propolis extract (PE) at 1%, 2% or 3% (w/v) on the quality parameters of pork meat during storage at 2 °C. Physical (pH, weight loss, color) and chemical parameters (percentage contents of metmyoglobin (MetMb), along with thiobarbituric acid reactive substances (TBARS)) were measured, and microbiological (total aerobic plate count (TAPC)) analysis, as well as consumer evaluation, was carried out every four days during the storage period of twelve days. The results indicated that the proposed treatments affected (p < 0.05) the quality characteristics of meat samples. The high prevention of physicochemical alterations and maximum inhibition of microorganisms was obtained for samples stored in gelatin coatings containing 2% and 3% PE. Additionally, despite a slight deterioration in odor on Day 4 in the P3 group, no negative changes in overall acceptability of the P2 and P3 groups compared to uncoated samples were observed. The obtained results indicate a significant role of propolis extract incorporation into gelatin packaging to extend the shelf life of stored pork.

All the changes related to composition, acidity, water activity, Free Fatty Acid (FFA), soluble nitrogen, 5-Hydroxy Methyl Furfural (HMF) and Thiobarbituric Acid (TBA), rheological, sensory and microbiological properties of rava burfi were found to be significantly (P<0.05) affected by storage period (i.e. 9 days at room temperature (30±2 °C) and 35 days at refrigerated (7±2°C) temperat ure). During storage period there was a decrease in moisture content (2.5 to 3.0%) and water activity and an increase in fat, protein, lactose, ash, added sugar, acidity, FFA, soluble nitrogen, TBA and HMF both at ambient (30±2 °C) a s well as at refrigerated (7±2°C) temperature. Changes in rhe ological attributes at both ambient and refrigerated temperatures of storage indicated that there was an increase in hardness, gumminess, chewiness and adhesiveness whereas there was decrease in cohesiveness and springiness values. The sensory scores in terms of flavour, body and texture, colour and appearance and overall acceptability were found to be significantly (P<0.05) decrease with progressive increase in storage period. The shelf life of rava burfi was found to be 9 days at room temperature (30±2 °C) and 35 days at refrigerated (7±2°C) temperature.

Over Time

The enrichment of semolina pasta with nutritionally rich ingredients has been targeted as a health strategy in recent years. In this work, the storage stability of seaweed-enriched pasta was assessed at different combinations of temperature and relative humidity. After six months of storage, pasta samples did not present variations in their sensory properties. The enrichment of durum wheat pasta with 1% of macroalgae Fucus vesiculosus and Ulva rigida flours, or flours of its extracts, was found to be adequate without influencing or modifying the sensory characteristics of pasta samples during the storage period. Water activity was shown to be the main criteria influencing the quality parameters of pasta during shelf life. A higher water activity during storage will lead to higher cooking losses and a lower firmness of cooked pasta, which will damage pasta quality over time.

Purpose This paper aims to explore the application of drumstick (Moringa oleifera) flower (DF) as a functional antioxidative ingredient in goat meat product. Design/methodology/approach Dried DF was included in the product formulation at 1% (Treatment I) and 2% (Treatment II) levels. The physicochemical, colour, textural and sensory quality as well as storage stability of nuggets with DF were determined against control. Findings The dried DF was found to be rich source of protein and dietary fibre, possessing good antioxidant potential. Chromatographic analysis of DF extract showed presence of 14 active principles known to have antioxidative properties. Inclusion of dried DF decreased pH values of emulsion (p = 0.005) as well as nuggets (p < 0.001) and increased (p < 0.001) the ash, dietary fibre and phenolic contents. The added DF affected the product’s lightness (p = 0.017), yellowness (p < 0.001, hardness (p < 0.001), adhesiveness (p = 0.032), cohesiveness (p = 0.006), gumminess and chewiness (p < 0.001). Sensory characteristics of control and product with DF were statistically similar except low (p = 0.002) flavour score for Treatment II. DF inclusion lowered (p < 0.001) thiobarbituric acid reactive substances number and total plate count. Research limitations/implications DF can be used as a source of antioxidants and dietary fibre in goat meat nuggets to enhance their health value, functionality and storage stability. Originality/value Foods including goat meat nuggets enriched with goodness of functional ingredients like dietary fibre and natural antioxidants are gaining consumer’s preference globally. Inclusion of drumstick flower in goat meat nuggets significantly increases the dietary fibre and antioxidants making such products healthier and more stable. Consumption of goat meat nuggets added with drumstick flower is expected to improve consumer’s well-being as well.

Goat Meat

Meat of non-descript type old female goat of more than two years age and meat of young castrated male goat of around 9 months age were procured, chilled to 4±1ºC for 24 hrs and then frozen stored at -10±1ºC in the form of chunks and mince, packaged in low density polythene (LDPE) -300 g (gauge) and high density polythene (HDPE) -200 g for 0, 4, 8, 12 and 16 weeks. Samples of meat were evaluated for pH, water holding capacity (WHC), salt soluble protein (SSP), water soluble protein (WSP), non protein nitrogen (NPN), thiobarbituric acid value (TBA) and microbiological load in terms of aerobic plate count (APC). Overall there was significant (P less than 0.01) rise in pH as the storage period progressed. There was non-significant (P less than 0.01) difference between treatments. The average WHC increased significantly (P less than 0.01) upto 8 weeks (32.87%) and then started decreasing and was lowest at 16 weeks (24.14%). There was significant decrease (P less than 0.01) in WSP as the storage period increased from 0 week to 16 weeks. The average WSP of old female goat meat kept as chunk in LDPE and mince in HDPE increased significantly (P less than 0.01) with respect to young male goat meat (kept as chunk in LDPE and mince in HDPE). There was significant (P less than 0.01) reduction in SSP as the storage period progressed but there was non-significant decrease between 4 weeks and 8 weeks. SSP was 8.53% at 0 week and 4.58 at 16 weeks. The average TBA-values increased significantly (P less than 0.01) at each storage interval. The value increased from 0.28 (at 0 week) to 0.65 (at 16 weeks) mg of malonaldehyde/kg of meat. Mince kept in HDPE of old female goat had significantly (P less than 0.01) higher TBA value than other treatments. There was significant (P less than 0.01) reduction (5.65 log10 cfu/g at 0 week and 5.26 log10 cfu/g at 16 weeks) at each storage interval in APC as the storage period increased.

Biochemical, microbiological and sensory quality parameters of mustard hilsa prepared from Hilsashad (Tenualosa ilisha) were examined to observe the changes in quality during storage at refrigerationtemperature (5° to 8°C) for 60 days and at frozen temperature (-18°C to -20°C) for 180 days. The moisture,protein, lipid, and ash content and pH value in mustard hilsa decreased compared to those obtained for freshfish. On the other hand, TVB-N and peroxide values increased compared to the values found in fresh fish. Atrefrigeration temperature and frozen temperature moisture and ash contents increased but protein and lipidcontent decreased gradually throughout the storage period. pH value of the mustard hilsa reduced from 7.22to 6.01 and 6.59 at refrigeration and frozen temperatures, respectively. The TVB-N value and peroxide valueincreased progressively throughout the storage period irrespective of storage temperatures. Rate of changes indifferent parameters of mustard hilsa was slower in vacuum sealed packs than non-sealed and sealed packs.The aerobic plate count of bacteria was increased in refrigeration temperature but the load of microbes wasreduced at frozen temperatures. The result of sensory quality change showed that, irrespective of storagetemperature and packing condition the scores of sensory quality parameters decreased with the progress ofstorage time though the decreasing rate was slower at frozen temperature. The study concluded that, atrefrigeration temperature mustard hilsa might remain in acceptable condition up to 60 days and at frozentemperature for about 180 days in vacuum sealed pack.

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.

Loss of market value of shrimp is mainly due to the formation of black spot called melanosis. A study was conducted for 14 days to determine the extent of melanosis and quality changes during that period of freshly har-vested whiteleg shrimp (Litopenaeus vannamei) under chilled storage (2℃). Among quality parameters, total volatile basic nitrogen (TVB-N), thiobarbituric acid reactive substances (TBAR-S), were varied from 13.17 mg % to 44.50 mg % and 0.04to 2.57 mg malondehaldehyde/kg of fat respectively whereas melanosis score and metric chroma (C) exhibited significant increases during chilled storage (P<0.05). There was a slight increase in moisture, crude fat and pH from 73.96 % to 74.57 %, 1.05 % to 1.14 % and 6.52 to 7.60 respectively at 14th day of storage. Loss of protein from 22.51 % to 21.28 % may be due to decrease in available amino acids during chilled storage and total plate count (TPC) showed gradual increase of bacterial load up to 1.73*107 log CFU/g at the end of chilled storage. The sensory analysis by panellists indicated, the acceptability of white leg shrimp was up to 6 days in chilled condition and formation of black spot is one of the major parameter for rejection by the panellists.

The present study was undertaken to evaluate the effect of different levels of corn flour on the quality characteristics of chicken meatball. The meatballs were formulated having 0, 05, 10 and 15% of corn flour. After formulation, samples were preserved at -20˚C for 60 days and analyzed the data at 0, 15, 30 and 60th day, respectively. The products were analyzed for various sensory, proximate, biochemical and physicochemical attributes. The sensory (color, flavor, tenderness, juiciness and overall acceptability), proximate composition- dry matter (DM), ether extract (EE), crude protein (CP) and ash, biochemical parameters- free fatty acid (FFA), peroxide value (PV) and thiobarbituric acid value (TBARS) and physicochemical (raw pH, cooked pH and cooking loss) were analyzed. Data were analyzed in a 4x4 factorial experiment in completely randomized design with replicated three times per cell. Results showed that corn flour inclusion in meatballs have no effect on sensory parameters, but the highest value for all sensory parameters was found at 15th day storage period, (p<0.05). After 15th day, with the increasing of storage period the value for all sensory parameters were decreased (p<0.05). The proximate component’s value were differ with treatment and day interval group (p<0.05). The highest value of raw pH and lowest value of cooking loss were found in 5% corn flour group (p<0.05). The highest value of cooked pH and lowest value of cooking loss were found at 15th day storage period. There were no effect of treatment or day interval on FFA and TBARS. Highest value of PV were found in 0% cornflower group (p<0.05). It may be concluded that 5% corn flour and 15 days storage period is suitable for chicken meat ball.Bang. J. Anim.
