Abstract

The Faculty of Animal Science, IPB University, produces pasteurized milk daily under the D-farm milk processing unit. In order to maintain the product quality, as well as its safety, the fresh milk as raw the main material and the produced pasteurized milk quality is tested periodically. The aim of this research is to evaluate the quality of fresh and pasteurized milk produced by the D-farm milk processing unit. The tested fresh milk was originated from two different farms, while the tested pasteurized milk was made by using pasteurizer machine and double-wall pan heating. The tests were carried out by using a lactoscan milk analyzer. The results showed that the fresh milk used by the D-farm milk processing unit had good milk quality, even though still below the SNI standard, while the produced pasteurized milk has met the SNI standard. In addition, the pasteurization by using pasteurizer produced better pasteurized milk quality compared to the traditional pasteurization by using double-wall pan heating.

Abstract

Egg white lysozyme (EWL) has considerably a wide functional protein exhibiting antibacterial activity mainly against Gram-positive bacteria. The EWL is widely applied in food industry and is considerably safe. Despite its high potency, EWL of Indonesian poultry has never been studied and exploited. This study was aimed to purify EWL from two Indonesian poultry: kampung chicken and Cihateup duck, and compared to egg of commercial laying hens. The eggs in this study were obtained from field laboratory of Faculty of Animal Science, Bogor Agricultural University (IPB) and classified in AA quality based on the interior quality. First attempt to purify the EWL was performed by using ethanol precipitation yielding purified EWL which was still contaminated by other proteins, hence designated as partially purified EWL. Final concentrations of partially purified EWL of kampung chicken, commercial laying hens, and Cihateup duck were about 5800, 5400, and 5500 μg/mL, respectively. To confirm whether the use of ethanol in the purification affecting EWL antibacterial activities, the activities were examined against Staphylococcus aureus. It demonstrated that the partially purified EWL exhibited ability to inhibit S. aureus at 6 and 26 h suggesting that the method was feasible as it did not interfere EWL antibacterial activities. Yet, based on SDS-Page, purity was the issue in ethanol precipitation method. Further attempt using ion exchange chromatography at pH 10 successfully purified lysozyme as indicated by a single band corresponding to lysozyme size (~14 kD) free from bands of other proteins. Altogether, a single step of ion exchange chromatography is sufficient and promising to isolate EWL from Indonesian poultry for various industrial purposes.Key words: Indonesian poultry, lysozyme, egg, kampung chicken, Cihateup duck

Abstract

Lysozyme is one of the proteins found in hen egg albumin. Besides known as antimicrobial agents, lysozyme hydrolysis products can also function as antioxidants and as angiotensin converting enzyme (ACE) inhibitors. The lysozyme is also known to have lysine and arginine that can give a sweet taste. The research aimed to isolate lysozyme from commercial laying hen eggs. The isolation and purification of the eggs lysozyme was done by preparative and analytical separation technique using cation exchange resins.  The preparative separation was carried out by centrifugation of a large sample size of 205 g by centrifuga-tion, while the analytical separation only used only 3.16 g sample with a column measuring 13 cm in length and 3 cm in diameter. The number of samples isolated by preparative separation is greater than that with analytical method. The preparative separation was conducted in order to obtain the pure isolated lysozyme in higher quantity for further testing purposes. The purity of the isolated lysozyme from preparative separa-tion was 68.62% and the purity of isolated lysozyme from analytical separation was 63.03%.

Processing is the way to solve that problem. Nasu palekko is a signature dish from South Sulawesi which made from duck meat and full of local spices. Nasu palekko has potentially fat oxidation reactions that impacted on decreasing quality. The addition of natural antioxidant ingredients can inhibit the fat oxidation process. This study was aimed to analyze the physicochemical, microbiology characteristics, and fat oxidation intensity during storage at room temperature with different processing method and shelf life. This study was used a completely randomized design (CRD) factorial 2x3 with 3 replications, consisting of 2 processing method (dry processing, wet processing) and 3 storage time (0 days, 2 days, 4 days).  The obtained data were analyzed using analysis of variance, and the significant result was further being tested by the Tukey test. The results showed that the treatment method had a significant effect (p<0.05) on all variables except  moisture content. Storage time had a significant effect (p<0.05) on most of the research variables, except pH and water activity. The results of microbiological analysis showed that there was significant effect (p<0.05) of treatment between processing methods and storage time. Based on this study, nasu palekko with dry processing method has lower pH, moisture content, water activity, MDA, and trimethylamine content. Higher intensity of fat oxidation occurs in wet processing. Based on the microbiological quality, dry and wet processing methods are still suitable for consumption until the fourth day of storage at room temperature.Keywords: meat ducks, nasu palekko, processing, storage

Abstract

Egg white is one source of protein that has many functions, including as an antimicrobial, antihypertensive, anti-cancer, and this can also be used as a preservative and sweetener. The addition of egg white powder to effervescent tablets with lemon essence is expected to increase protein levels in the tablet. The purpose of this study was to study the physical, chemical and organoleptic characteristics of effervescent tablets by adding egg white powder to the formulation. The study design used a randomized block design (RBD) with the making period as a group. The treatments used were different concentrations of effervescent mix (sodium bicarbonate, citric acid and tartaric acid), that is, 55, 60 and 65%. Data from the test results were tested with analysis of variance (ANOVA), further tests with the Duncan test. The physical characteristics of effervescent tablets with the addition of egg white powder and the difference in the concentration of effervescent mix as a treatment were not significantly different among treatments. The chemical characteristics of egg white effervescent tablets did not change with the treatment concentration of effervescent mix 55, 60 and 65% but the water activity (aw) of the effervescent tablets changed. Increasing the concentration of effervescent mix treatment can reduce the value of aw from 0.58 to 0.50. The addition of albumen powder with different concentrations of effervescent mix resulted in effervescent tablets according to predetermined standards. The organoleptic test results on the overall assessment of egg white powder effervescent tablets were somewhat favorable

Abstract

Jerky is a processed meat product that can have rancidity due to storage. Adding fresh red ginger as a spices can inhibit the growth of bacteria, increasing antioxidant activity, and potentially increasing tenderness. This study aims to examine the characteristics of beef jerky added by fresh red ginger (Zingiber officinale var. Rubrum) as a seasoning. This study used the addition of fresh red ginger with proportion 0%, 12,5% and 25% from meet weight. Beef was sliced with a thickness of 5 mm then was marinated with spices for 12 hours. Marinated beef was dried using oven at 60°C for 3 hours and 70°C for 5 hours. The results showed that the addition of fresh red ginger to beef jerky was able to increase pH, aw, moisture content, DPPH inhibitory activity, and antioxidant capacity, as well as reduce hardness, TBARS value and TPC numbers. Salmonella sp., Escherichia coli and Staphylococcus aureus bacteria were not detected in all treatments and storage. The red ginger concentration of 12.5% in both raw and cooked beef jerky was preferred by the panelists. Beef jerky with the addition of 25% fresh red ginger showed the best results for testing the physicochemical, sensory, microbiological, and antioxidant activity properties.
