Allium mongolicum is a kind of plant with edible, medicinal and feeding value. The effects of ethanol and water extracts of Allium mongolicum on thiobarbituric acid reactive substances (TBARS), nitrite residue, carbonyl group, volatile base nitrogen (TVB-N) and microstructure were investigated in pork dry-cured sausages during ripening. Without added extracts groups were adopted as negative controls (CK), and adding ascorbic acid groups (VC) were used as positive controls. Results showed that compared with CK, TBARS of ethanol, water extracts and VC groups were significantly reduced. Ethanol extracts, water extracts and VC significantly decreased residual nitrite of sausages (P <0>05) comparing with CK. Ethanol extracts have better ability than water extracts in reducing carbonyl content and TVB-N. The microstructure of the CK was the worst, and the microstructure of ethanol extracts group was the best. It was concluded that ethanol extracts of Allium mongolicum could be used to produce dry-cured sausage to improve safety and quality.

Antioxidant And Antimicrobial Activities

Pork is perishable due to oxidation and microbial spoilage. Edible coating based on biopolymers and phenolic compounds is an effective way to preserve the quality of pork. In this study, ferulic acid-grafted-CS (ferulic acid-g-CS) with strong antioxidant and antimicrobial activities was synthesized through a carbodiimide-mediated coupling reaction. The obtained ferulic acid-g-CS was used as an edible coating material for fresh pork. The effect of ferulic acid-g-CS coating on the quality of pork during storage was investigated at 4 °C for 8 days. As compared to the uncoated pork, pork coated with CS and ferulic acid-g-CS showed lower total viable counts, total volatile basic nitrogen values, pH values, thiobarbituric acid reactive substances, and drip losses. Besides, pork coated with CS and ferulic acid-g-CS presented more compact microstructures than the uncoated pork at the eighth day. Sensory evaluation assay showed pork coated with CS and ferulic acid-g-CS had better color, odor, and over acceptance in comparison with the uncoated pork. Ferulic acid-g-CS coating, due to its relatively higher antioxidant and antimicrobial activities compared to CS coating, had a better performance in refrigerated pork preservation. Ferulic acid-g-CS coating effectively extended the shelf life of refrigerated pork to 7 days. This study revealed ferulic acid-g-CS coating was a promising technology for refrigerated pork preservation.

The aim of this study is to evaluate the effects of Psidium guajava leaves extract on the quality of cobia (Rachycentron canadum) fillets during in ice storage. A group of cobia fillets was soaked in Psidium guajava extract solutions at concentration of 0.03% (w/v) for 30 minutes while the other group soaked in cold ice water, considered as control treatment. The experimental fillets were packed and stored in ice for 15 days. Sampling were done on the 1st, 5th, 10th and 15th day. Analyzed parameters included temperature, total viable counts (TVC), sensory property, pH, moisture, water holding capacity (WHC), texture, total volatile base nitrogen (TVB–N), peroxide value (PV), Thiobarbituric acid reactive substances (TBARs), and fillet color. The results indicated that cobia fillets treated with guava extract solutions 0.03% showed significantly higher sensory property, lower PV and TBARs compared to the control treatment during ice storage. Based on the sensory property and total viable counts, cobia fillets can be used up to 10 days in both treatments remaining high quality of the cobia fillet.

Uniform design was adopted, and two factors, i.e., frozen at different time postmortem with six levels, thawing at different thawing rate with three levels, were considered. Thiobarbituric acid reactive substances (TBARS), pH and sensory evaluation were measured to study the different effects of the two factors considered. The results showed: All the two factors considered had significant effects on pH and TBARS, and the effects of the two factors on them were nonlinear. But they had no significant effects on sensory evaluation. TBARS values representing the storage quality of raw sausages was only affected by thawing rate in the test, and had the maximum at the thawing rate of 3cm/h thawed in 19.5°C still air. So when using frozen raw meat for sausage production, selecting an appropriate thawing condition is very necessary.

The work deals with a study of the effect of natural antioxidants – rosemary extracts in powder and liquid forms, respectively, on the quality of a heat-untreated meat product. Effect of added antioxidants was estimated in samples taken from the meat product mixture, from a ready-made product immediately after smoking, after 28 days – at the expedition of the meat product and then after further 28 days of storing at different ambient temperatures. Marked positive effect of the applied antioxidants was noted especially during storing when the peroxide and thiobarbituric acid reactive substances (TBARS) values of fats increased more slowly compared to meat products manufactured without added antioxidants. Subsequent sensory analysis shows also preferences for the antioxidant treated meat products.

In this study different methods were used to evaluate the effectiveness of a carrageenan coating and carrageenan coating incorporating lemon essential oil (ELO) in preserving the physicochemical and olfactory characteristics of trout fillets stored at 4 °C up to 12 days. The fillet morphological structure was analyzed by histological and immunological methods; lipid peroxidation was performed with the peroxide and thiobarbituric acid reactive substances (TBARS) tests. At the same time, two less time-consuming methods, such as Attenuated Total Reflectance-Fourier Transformed Infrared (ATR-FTIR) spectroscopy and the electronic nose, were used. Uncoated trout fillets (UTF) showed a less compact tissue structure than carrageenan-coated threads (CTF) and coated fillets of carrageenan (active) ELO (ACTF), probably due to the degradation of collagen, as indicated by optical microscopy and ATR-FTIR. UTF showed greater lipid oxidation compared to CTF and ACTF, as indicated by the peroxide and TBARS tests and ATR-FTIR spectroscopy. The carrageenan coating containing ELO preserved the olfactory characteristics of the trout fillets better than the carrageenan coating alone, as indicated by the electronic nose analysis. This study confirms that both carrageenan and ELO containing carrageenan coatings slow down the decay of the physicochemical and olfactory characteristics of fresh trout fillets stored at 4 °C, although the latter is more effective.

Abstract The purpose of the study was to increase the nutritional quality of pork, and to investigate the effect of the synbiotic on the oxidative stability of lipid. A 4 weeks experiment was performed on 8 weaned piglets (age 47 days, TOPIGS), divided into 2 groups (C, E). The control group (C) received a conventional diet, while the experimental group (E) included a diet supplemented with organic Zn and 10 g/kg synbiotic mixture. The productive parameters were evaluated. After slaughtered, muscle (tenderloin, shoulder, loin, ham and belly) and organs samples (liver, spleen and kidney) were collected. The muscle and organs samples were analysed regarding the proximate chemical analysis (dry matter, crude protein, crude fat, and ash). The antioxidant capacity and thiobarbituric acid reactive substances (TBARS) were performed on shoulder and ham samples at first day of the trial, 4 and 7 days after refrigeration. The crude fat determined in the loin samples, recorded a significant increase in the E group compared to the C group. The ash was higher in the shoulder samples from C group than in E group. At 7 days of refrigeration, the MDA concentration was significantly lower in the shoulder and ham samples from E group than those from C group. The conclusion was that the diet supplemented with organic Zn and 10 g/kg synbiotic mixture contributed to the delay of the lipid oxidation process of the shoulder and ham samples during the refrigeration period.

ABSTRACT: This study evaluated the effects of intramuscular alpha-tocopherol (vitamin E) supplementation on meat quality characteristics of Santa Inês and Dorper crossbreed lambs. All animals were feed with a high concentrated diet in feedlot. Eight days before slaughter, the animals were distributed into four blocks according to weight gain. At the seventh and fourth days before slaughter, they were intramuscularly treated with 0, 10 or 20 IU of DL-alpha-tocopherol per kg of metabolic body weight. At slaughter they had 138 days of age and 43.6 kg of live weight, in average. Carcasses were stored for 24 hours under refrigeration at 2°C. Longissimus thoracis muscle pH (pH24h) and color (lightness, yellowness and redness) were analyzed and its samples were collected for evaluation of shear force (SF), cooking loss (WLC), fatty acid composition (FA) and thiobarbituric acid reactive substances after one (TBARS1m) and after five months (TBARS5m) of freezing. Linearity deviation effect was observed for lightness (L*; P=0.0042) and yellowness (b*; P=0.0082). Intramuscular administration of 10 or 20 IU of alpha-tocopherol/kg of metabolic weight did not influence the conservation of fatty acid in the carcasses, but benefit L* and b* values.

The aim of this study was to evaluate the oxidative stability of fresh lamb patties from Longissimus dorsi (LD) muscle, obtained from animals slaughtered at 10 months-age, during 9 days under refrigerated storage. Six batches (n = 6) of lamb patties were prepared and analyzed for thiobarbituric acid-reactive substances (TBARS), and for carbonyl content throughout 9 days at 4 °C. TBARS levels were stable (p > 0.05) during first five days of storage and a decrease (p < 0.05) in lipid oxidation was observed on day 9. Carbonyl content increased (p < 0.05) up to day 5, remaining constant (p > 0.05) from day 5 to day 9. We concluded that fresh lamb patties from LD muscle of animals slaughtered with 10 months of age was relatively stable to oxidative process during refrigerated storage without additional treatment, which may represent a viable and interesting alternative for refrigerated meat market.

The efficacy of pulsed UV (PUV) light treatment carried out in a wide range of fluence was investigated on pastirma slices by characterizing Staphylococcus aureus inactivation using mathematical models and by assessing the treatment effects on quality attributes. Pastirma slices inoculated on top surface with S. aureus were subjected to pulsed UV light for 5, 15, 25, 35, and 45 s at 5, 8, and 13 cm from the quartz window. Although the 5 cm/45 s treatment (72.3 J/cm2) yielded a maximum reduction of 2.99 log cfu/cm2 for S. aureus, this treatment changed the color, moisture, and thiobarbituric acid-reactive substances (TBARS) values of pastirma significantly ( p < 0.05). The quality of pastirma tended to change above 20 J/cm2, below which the highest log reduction of S. aureus was ∼1.3 log cfu/cm2 obtained after the 8 cm/15 s treatment (18 J/cm2). Kamau’s model provided better fit to inactivation data (root mean square error: 0.049–0.116, Af: 1.013–1.046, R2: 0.991–0.999) than Cerf’s and Weibull models.

Unstable Temperature

The effect of glazing and storage temperature on lipid oxidation and sensory properties of mackerel fillets was evaluated. A total of 288 fillets were stored for 6 months under stable temperature of –18 °C and unstable temperature, which involved six temperature fluctuation cycles from –18 to –5 °C each month. Glaze determination, chemical composition, thiobarbituric acid reactive substances examination and sensory evaluation of fillets were performed. Glazing and stable temperature conditions slowed down lipid oxidation in fillets compared to unglazed samples and samples stored under unstable freezing conditions. The thiobarbituric acid reactive substances increased slowly in glazed samples and a positive effect of stable conditions was found after two months and became obvious from the fifth month of storage. Sensory scores included evaluation of taste, aroma, texture, juiciness, and appearance corresponded to chemical results. Glazed fillets had the best scores in sensory evaluation and can be recommended for consumption; on the other hand, unglazed fillets stored under unstable temperature could not be consumed because of rancidity. This is the first similar study in mackerel when unstable temperature conditions are considered as a factor increasing lipid oxidation. Prevention of temperature fluctuation during storage is important to keep the quality of the frozen fillets.
