Organoleptic Attributes

The present study was conducted to assess the impact of chitosan coating (1%) containing Artemisia fragrans essential oil (500, 1000, and 1500 ppm) as antioxidant and antimicrobial agent on the quality properties and shelf life of chicken fillets during refrigerated storage. After packaging meat samples, physicochemical, microbiological, and organoleptic attributes were evaluated at 0, 3, 6, 9, and 12 days at 4 °C. The results revealed that applied chitosan (CH) coating in combination with Artemisia fragrans essential oils (AFEOs) had no significant (p < 0.05) effects on proximate composition among treatments. The results showed that the incorporation of AFEOs into CH coating significantly reduced (p < 0.05) pH, thiobarbituric acid reactive substances (TBARS), and total volatile base nitrogen (TVB-N), especially for 1% CH coating + 1500 ppm AFEOs, with values at the end of storage of 5.58, 1.61, and 2.53, respectively. The coated samples also displayed higher phenolic compounds than those obtained by uncoated samples. Coated chicken meat had, significantly (p < 0.05), the highest inhibitory effects against microbial growth. The counts of TVC (total viable counts), coliforms, molds, and yeasts were significantly lower (p < 0.05) in 1% CH coating + 1500 ppm AFEOs fillets (5.32, 3.87, and 4.27 Log CFU/g, respectively) at day 12. Organoleptic attributes of coated samples also showed the highest overall acceptability scores than uncoated ones. Therefore, the incorporation of AFEOs into CH coating could be effectively used for improving stability and shelf life of chicken fillets during refrigerated storage.

To investigate the effectiveness of adding lemon peels and pulp extracts on some quality properties and shelf-life of the sheep longisimussdorsi muscle during refrigerated storage at 4±1°C for 0, 4, and 8 days for this purpose am meat trim of visible fat and connective tissue, they cut in small cubes. The meat samples divide into four equal proportions and mix with different concentrations of lemon peel and pulp extract according to the following formulations: Control; T1 1%; T2 2% and T3 3% of lemon peel and pulp extract, by applied immersion method. The results showed acceptable results of moisture content, Water-holding capacity cooking loss, thiobarbituric acid, met-myoglobin, myoglobin, and sensory traits of the samples treated with lemon peel in comparison to the control group. The phiso-chemical traits changed during the storage periods but the meat sample treated with lemon extract was more stable than control groups. These results suggested that using lemon peels and pulp extracts to maintain physio-chemical properties of ram meat and extend shelf-life during refrigerated storage, which may have implications of meat processors.

The present study aimed to develop a novel active edible film based on gelatin incorporated with 0, 0.3, 0.6, and 0.9% w/w anise essential oil as a natural preservative and investigate the shelf life extension potential of chicken fillets during 12 days of refrigerated storage. The chicken fillets were wrapped with the essence-free and anise essential oil-loaded gelatin films, and microbial counts, chemical and sensory tests were surveyed during chilled storage. Results showed that aerobic mesophilic bacteria and Pseudomonas spp counts significantly decreased at all levels of anise essential oil during the first week of storage, while psychrotrophs, yeasts, and molds numbers began to reduce at concentrations of 0.6 and 0.9% from day 6. The using of anise essential oil caused a significant decrease of chemical parameters of chicken fillets, and the values of pH, peroxide, thiobarbituric acid reactive substance, and total volatile basic-nitrogen reached from 7.42, 5.7 meq/kg, 2.21 mg malondialdehyde/kg, and 24.94 mg N/100 g for the essence-free wrapped samples to 4.8, 6.35 meq/kg, 1.73 mg malondialdehyde/kg, and 18.78 mg N/100 g for the ones wrapped with 0.9% anise essential oil-loaded gelatin films at the end of storage day. In conclusion, application of gelatin films loaded with 0.6 and 0.9% anise essential oil can be advised for wrapping chicken fillets to prolong the shelf life for at least one week.

The Impact

As the global meat market moves to never frozen alternatives, meat processors seek opportunities for increasing the shelf life of fresh meats by combinations of proper cold chain management, barrier technologies, and antimicrobial interventions. The objective of this study was to determine the impact of spray and dry chilling combined with hot water carcass treatments on the levels of microbial indicator organisms during the long-term refrigerated storage of beef cuts. Samples were taken using EZ-Reach™ sponge samplers with 25 mL buffered peptone water over a 100 cm2 area of the striploin. Sample collection was conducted before the hot carcass wash, after wash, and after the 24 h carcass chilling. Chilled striploins were cut into four sections, individually vacuum packaged, and stored to be sampled at 0, 45, 70, and 135 days (n = 200) of refrigerated storage and distribution. Aerobic plate counts, enterobacteria, Escherichia coli, coliforms, and psychrotroph counts were evaluated for each sample. Not enough evidence (p > 0.05) was found indicating the hot water wash intervention reduced bacterial concentration on the carcass surface. E. coli was below detection limits (<0.25 CFU/cm2) in most of the samples taken. No significant difference (p > 0.05) was found between coliform counts throughout the sampling dates. Feed type did not seem to influence the (p > 0.25) microbial load of the treatments. Even though no immediate effect was seen when comparing spray or dry chilling of the samples at day 0, as the product aged, a significantly lower (p < 0.05) concentration of aerobic and psychrotrophic organisms in dry-chilled samples could be observed when compared to their spray-chilled counterparts. Data collected can be used to select alternative chilling systems to maximize shelf life in vacuum packaged beef kept over prolonged storage periods.

Studies on plantain chips fried with varietal stored tiger nut oil were studied. Three different tiger nut cultivars were sourced from Benue state and their oil extracted using hexane in an extractor. The stored oils were used to fry plantain chips after potatoes slicing and oil quality and stability analyzed. The moisture values of the chips from 0 week to week 12 for sample (A) ranged between 2.09-2.41 and 2.08-3.48 for samples (B) and (C) respectively .The thiobarbituric acid value from zero week - week12 for sample B O ranged between 0.19-0.21malon mg, sample BO ranged between 0.27-0.36 malon mg, while sample C ranged between 0.23-0.24malom mg. The appearance, aroma, taste, texture and overall acceptability of the chips ranged between 6.25-7.40, 6.20-6.55, 6.30-6.45, 6.20-6.55 and 6.15-6.55 respectively. Sample A and CKO (control) was most preferred in terms of appearance, aroma, taste, texture (crispness) and overall acceptability while sample A and C was least preferred. The sensory scores of the plantain chips fried with the oil were high for taste and aroma. During the storage, moisture values and thiobarbituric acid values of the chips were within the limits as recommended by CODEX Alimentarius.
