Vietnamese fermented pork roll (Nem Chua) is delicious by its distinctive and unforgettable sweet, crunchy and spicy feeling. It becomes a specialty of many regions in Vietnam. Recently consumers always pay much attention to hygiene. Spices and herbs can be considered as alternatives of artificial additives. This research evaluated the possibility of chilli powder incorporated to Vietnamese fermented pork roll (Nem Chua) during storage. Different percentages of chilli powder (0÷2.5 %) were added Nem Chua. In 12 hour-interval, samples were taken to examine Enterobacteriaceae load, pH, thiobarbituric acid value (TBA), total volatile bases nitrogen (TVB-N), overall acceptance (sensory score). During 60 hours of lactic fermentation, Enterobacteriaceae load decreased with the amount of chilli powder added. On the control sample, Enterobacteriaceae load increased during storage. Much more reduction of pH value was noticed when increasing chilli powder. There was a significant retardation of TBA and TVB-N accumulation by chilli powder addition. At 1.5% of chilli powder supplemented, the highest sensory score was noticed. Chilli powder would be a promising natural spice to control food hygiene and maintain physciochemical and sensory attributes of meat products.

Changes in physical, chemical, microbiological and sensory qualities of cooked crayfish (Procambarus clarkia) meat, treated at different freezing rate (-30°C,CPF; -60°C,ULTF; -196°C,LNM), were investigated during storage at -20°C for up to 6 months. pH value increased in all treatments with the sharp reduction after 3 months. Increase in weight loss of LNM was slower than that of CPF and ULTF cooked crayfish. During frozen storage, thiobarbituric acid value (TBA value) fluctuated in all treatments, but lipid oxidation did not affect the quality of crayfish meat because of its lower fat contents. Total volatile basic nitrogen (TVB-N) increased with storage time, with the reduction of TVC and sensory score. Freezing rates could not cause significant changes in chemical qualities (pH value, total volatile basic nitrogen, thiobarbituric acid value), sensory quality and microbiological quality for all three treatments during storage. In spite of decrease of quality of cooked crayfish meat in all treatments, good edibility was kept throughout the storage.

Khiaosa-ard R., Chungsiriwat P., Chommanart N., Kreuzer M. and Jaturasitha S. 2011. Enrichment with n-3 fatty acid by tuna oil feeding of pigs: changes in composition and properties of bacon and different sausages as affected by the supplementation period. Can. J. Anim. Sci. 91: 87–95. Belly, lean from the shoulder and backfat obtained from 80 pigs, fed either no or 1.6 kg tuna oil during fattening (35–90 kg body weight), were used to prepare bacon, Chinese-style sausage and Vienna-style sausage. The tuna oil had been supplemented either initially, at the end, or continuously during fattening. In all meat products, tuna oil supplementation clearly increased contents of n-3 fatty acids (FA), especially of the long-chain n-3 FA. Differences among supplementation periods were pronounced only in the n-3 FA proportion of total FA being lower with early tuna oil feeding. Thiobarbituric acid value, which was high in dry Chinese-style sausage, was mostly enhanced by tuna oil, whereas the period of tuna oil supplementation had no systematic influence. In conclusion, any mode of tuna oil supplementation investigated was efficient in enriching n-3 FA, but care should be taken in producing dry sausages due to their susceptibility to rancidity during storage time.

The aim of this trial was to investigate changes in chemical and physico-chemical parameters during the production of traditional Sremska sausage (dry fermented sausage) from pork of three pig breeds: Mangalitsa (MA), Moravka (MO) and Swedish Landrace (SL). Analyses of all variants of sausages were carried out after stuffing (day 0) and on production days 3, 7, 14 and 21. The reduction in moisture during production caused the increase in protein, fat and ash contents (p<0.001) in all three variants of sausages, were found to be within the range for this type of sausages. Higher fat content in MA and MO sausages compared to SL variant was most likely a result of the different chemical composition of the meat from pigs of autochthonous breeds. All three sausage variants had a similar final pH value, but the mildest drop of pH was determined in MA sausages. Pig breed significantly affected (p<0.05) all three indicators of oxidative changes (thiobarbituric acid value, peroxide value and free fatty acid content). It was found that they were higher in SL compared with MA and MO sausages and to significantly increase during the production process.

Abstract Meat is a highly nutritious food rich in protein, fat, vitamins, and minerals. Nevertheless, chemical reactions and microorganisms might affect the quality of nutritional constituent of meat products. This study investigated the influence of adding Moringa oleifera leaves powder (MOLP) on the nutritional, technological properties, and consumer acceptability of mutton patties. Four treatments of mutton patties with 0, 0.3, 0.6, and 0.9% of MOLP were produced. The prepared patties (raw and cooked) were evaluated for quality attributes such as proximate composition, total phenolic content (TPC), cooking properties (cooking yield and cooking loss), physical characteristics (colour and water holding capacity [WHC]), thiobarbituric acid reactive substances (TBARS), pH value, and sensory quality. The incorporation of MOLP into the mutton patties significantly increased (p < 0.05) protein, fat, ash contents, TPC, pH, WHC, and cooking yield. However, moisture content, TBARS, and colour decreased. Most sensory likability scores of patty samples with up to 0.3% of MOLP were comparable to those of the control sample. Evidently, the inclusion of 0.3% of MOLP produces mutton patties with high sensory desirability.

Melon Seed Oil

The physical value of oil depends upon its chemical composition, even today these values play a vital role while using different oil for industrial products and also, despite the vast nutritional and medicinal significance of egusi melon, there are little details on the shell life and stability of its oil over time. Therefore, the influence of time and temperature on melon seed oil was investigated at temperatures of 0oC and 30oC at different weeks to ascertain its physicochemical value and storage stability. For week zero, at 0oC and ambient temperature (30oC), the result revealed iodine value 124.09, Acid value 3.64 mgNaOH/g, Free Fatty Acid value 1.84 mgNaOH/g, Saponification 217.35 mgKOH/g, Peroxide value 1.25 mg/g oil, pH 5.89 and thiobarbituric acid value 0.1383 respectively. In the 5th week, at 30oC, the result revealed iodine value 91.1543, acid value 12.8921 mgNaOH/g, free fatty acid value 6.4988 mgNaOH/g, Saponification 346.42 mgKOH/g, Peroxide value 9.5mg/g oil, pH 3.2 and thiobarbituric acid value 0.413 respectively. Also at 0oC in the 5th week, the results were observed as follow: Iodine value 102.53, Acid value 7.96 mgNaOH/g, Free Fatty Acid value 4.01 mgNaOH/g, saponification 287.51 mgKOH/g, Peroxide value 6.1 mg/g oil, pH 5.05, and thiobarbituric acid value 0.2658 respectively. Refrigeration (0oC) of oil reduced the rate of most of the oxidative deterioration that produces rancidity. These values are within recommended range for edible oils. These results indicate that egusi melon oil could be a good source of table oil. The statistical results show that there was a significant difference between the melon seed oil stored at 0oC and 30oC (P < 0.001).

The effects of gamma irradiation and ozone treatment on microbiological and physicochemical properties of bee pollen were investigated. Gamma irradiation at 7.5 kGy reduced the total microbial loads below detection levels (&gt;102 CFU g−1) but after ozone treatment of up to 18 ppm for 8 h the total aerobic bacteria were found in concentrations of more than 103 CFU g−1. Physicochemical properties such as amino acid and fatty acid composition, thiobarbituric acid value, mineral content, and pigment were not significantly changed by gamma irradiation, whereas ozone treatment caused significant changes in fatty acid composition, thiobarbituric acid value, and pigment by lipid oxidation and decoloration (P &lt; 0.05).

A research was designed to study the effect on inhibiting the photosensitized oxidation of natural (lycopene) and synthetic (tertiary butylhydroquinon, TBHQ) antioxidant in soybean oil. In the presence of light, mean value of all samples revealed that a significant increase in peroxide value, free acid value and thiobarbituric acid (TBA) assay. The addition of lycopene and TBHQ reduced the peroxide value of control sample from 12.810 to 7.378 and 9.882 meq/kg, respectively. And TBA was found to be 0.163 in control sample, while the values of lycopene and TBHQ treatments were 0.080 and 0.134. Meanwhile, the oil samples were treated with different does of lycopene under light, the rate of oxidation increased considerably with a corresponding decrease in the content of lycopene. The data showed that oils containing 300 ppm lycopene had the lowest levels of free fatty acid value.The results indicated that lycopene in soybean oil exposed to light were found to be effective in inhibiting lipid oxidation.
