Abstract

The research aims to determine the effectiveness of pandan wangi (Pandanus amaryllifolius Roxb.) leaves extract (PWLE) as flies repellent and understand its effect on the organoleptic qualities of chicken meat. The study was conducted in a completely randomized design with PWLE concentrations (0, 5, 10, 15, and 20%) as research treatments and replicated for four times. The flies repelling data were analyzed by using ANOVA and followed with Least Significance Different (LSD) test. Moreover, the organoleptic test results were analyzed by using Kruskal Wallis test. The results showed that the immersion of chicken meat in PWLE was effective to reduce the number of flies contamination with a repellent level of 0%; 8.25%; 36.5%; 53% and 59%, on the PWLE addition at 0, 5, 10, 15 and 20%, respectively. The results of the organoleptic test showed that the PWLE affected the preference of panelists on color, aroma, and texture parameters.

Abstract

The objectives of this experiment were to evaluate the effect of using meat obtained from cull Bali cows differing in body condition score (BCS) on sensory property and benzo(a)pyrene (BaP) level on se’i (Rotenesse smoked beef). A completely randomized design 9x3 was used in this experiment. The nine treatments were BCS 2 with open smoking method (BCS2O), BCS 2 with close smoking method (BCS2C), BCS 2 given liquid smoke (BCS2LS), BCS 3 with open smoking method (BCS3O), BCS 3 with close smoking method (BCS3C), BCS 3 given liquid smoke (BCS3LS), BCS 4 with open smoking method (BCS4O), BCS 4 with close smoking method (BCS4C), and BCS 4 given liquid smoke (BCS4LS). Parameter measured were sensory property and benzo(a)pyrene (bap) content of se’i. The data of sensory property were analyzed using Kruskal-Wallis test followed by Mann-Whitney test. The data of benzo(a)pyrene (BaP) content was analysed using analysis of variance followed by Duncant test. Results showed that se’i produced from group BCS4LS possessed higher score on taste and tenderness, whereas the strongest aroma of se’i was found in se’i processed by both open and close smoking method in all BCS group. The highest benzo(a)pyrene content (0.0052 – 0.0055 ppm) was found in se’i processed by close smoking method in all BCS group, followed by se’i was added liquid smoke in all BCS group. It is suggested that meat of cull Bali cows with BCS4LS could be used to produce se’i with preferable taste,n tenderness and could lower the accumulation of BaP in se’i.

Abstract

The leaf of Dracaena angustifolia has been used widely not only as natural food colorant but also as a natural source of vitamin C. The objective of this study was to obtain the best addition level of Dracaena angustifolia leaves aqueous extract as natural food colorant for milk toffee based on its effect on texture, color, vitamin C and reducing sugar content. Milk toffee was formulated with different addition levels of Dracaena angustifolia leaves aqueous extract as treatment; 3%, 4%, 5%, 6% on weight/milk volume basis, and compared to control (0%). Higher addition level of Dracaena angustifolia leaves aqueous extract to milk toffee resulted in higher (P<0.01) L*, a*, b* values, and softer texture. Vitamin C and reducing sugar content were increased by the addition of 4% extract. However, there were no further differences on vitamin C and reducing sugar content when the addition level was increased up to 6%. Therefore, among treatments, the highest addition level used in this study (6%) is suggested as the best addition level according to texture, color, vitamin C content and reducing sugar content of milk toffee. The addition of natural food colorant, which contains antioxidant, e.g. Dracaena angustifolia leaves aqueous extract, also promotes the diversification of milk toffee.

Abstract

Red beetroot is rich in phenolic acids and betalain as natural food-coloring agents. Freeze-dried red beetroot that ground into powder can be used as a source of natural coloring to substitute the use of synthetic food color additives as well as filler to substitute tapioca. This study evaluates the function of red beetroot powder not only as filler but also as coloring agent on chicken sausage. Furthermore, its effects as filler (tapioca and beetroot) were also observed on the physical and sensory characteristics of the produced chicken sausage. The substitution of tapioca flour and beetroot powder in this study were 18:0, 17:1, 16:2, and 15:3 (%:%). Each treatment was consisted of three replications. The examined physical properties include pH, water-holding capacity (WHC) and sensory properties. The study found that WHC, color, texture profile and sensory properties were influenced by the increasing level of beetroot flour ratio, while different ratios had no effect on the pH. Chicken sausages made with higher ratio of beetroot flour had good acceptability on flavor and color. The conclusions of this study were substitution tapioca with 2% beetroot powder influenced physical quality (water holding capacity and tenderness) and sensory (color and flavor) of chicken sausage.

Abstract

To maximize the performance of the fermentation process, there is a need for a biactivator. The purpose of this study was to evaluate the characteristics of compost-based waste from cattle dung (CD) combined with rice straw (RS) by applying white rot fungus (Wrf) (Ganoderma sp) as a bioactivator.  In this study, 6 types of treatments have been applied, namely T1(CD:RS)(25%:75%)+5% of Wrf; T2(CD:RS)(50%:50%)+5% of Wrf; T3(CD:RS)(75%:25%)+5% of Wrf; T4 (CD:RS)(25%:25%)+0% of Wrf; T5(CD:RS)(50%:50%)+0% of Wrf; T6 (CD:RS)(75%:25%)+0% of Wrf. The study was designed experimentally using a completely randomized design (CRD), 6 treatments with 3 replications.  Based on the research results, the difference in the ratio of CD to RS and the use of Wrf bioactivator has a significant effect (p<0.05) in increasing the pH, temperature, C-organic and C/N ratio in compost. However, this difference had no significant effect (p>0.05) on the C-organic value. The pH value of compost was obtained with variations of 5.50±0.43-6.73±0.06. Temperature of compost is in the range of values 24.00±0.00-25.67 ±0.58 ºC. The C-organic value is in the range of 24.38±0.48-31.32±0.80%, while the N-organic value varies at 1.34±0.11-2.10±0.15%. The C/N ratio is in the range of 15.00± 0.11-19.33±1.15. Based on the interaction, the results showed that there was a significant interaction (p>0.05) between the use of Wrf bioactivator with the ratio of CD to RS on the parameters of pH, N-organic and C/ Nratio, while, C-organic and temperature had no significant effect.  The results of the study was concluded that several test parameters produced compost characteristics that were in accordance with Standar Nasional Indonesia (SNI) and the Regulation of the Minister of Agriculture of the Republic of Indonesia. Compost production using T3 treatment ((CD:RS)(75%:25%) + 5% of Wrf) produces the best characteristics compared to other treatments.

Abstract

Improving comminuted meat products characteristics using a natural agent, such as phytochemicals, in order to replace the use of nitrite, have become a need due to the health reason. The quality of the sausage is also affected by the initial characteristics of the dough. Therefore, this research was conducted to investigate the effect of aqueous leaf extract of senduduk (Melastoma malabathricum L.) on the physicochemical properties of beef sausage dough. Different four formulas as treatment were employed to form the dough: formula A was as a control consisted of beef meat, vegetable oil, skim milk powder, tapioca, salt, phosphate, and seasoning; formula B was control added with extract 0.55%; formula C was control added with sodium nitrite 0.0011%, and formula D was control added with extract 0.55% and sodium nitrite 0.0011%. All ingredients were blended to be the dough. The result of the study denoted that the extract (B and D) significantly decreased (P<0.05) pH, and aw value with no difference in water content among the dough. The total phenolic content of the dough containing extract (B and D) was markedly higher (P<0.05) than were others. It increased significantly on antioxidant capacity, scavenging activity, and reduced the thiobarbituric acid reactive substances (TBARS) value of the dough. There was also no nitrite residual detected in all dough. In conclusion, the extract could improve the physicochemical properties of beef sausage dough and replace the use of nitrite in the dough.

Abstract

The texture of sausage was affected by its binding agent. Elephant foot yam (Amorphophallus campanulatus) flour was a potential natural binding agent and filler for sausage. The objective of this study was to evaluate the effect of elephant foot yam flour and soybean oil addition to the physicochemical properties and sensory attributes of beef sausage. A randomized block design with two factors and three replications were employed. Three addition levels (10%, 15% and 20% of meat weight) were used for both elephant foot yam flour and soybean oil. The results showed that the addition of elephant foot yam flour significantly (P≤0.01) affect the water-holding capacity (WHC) and sausage texture. The effect (P≤0.05) was also observed on the redness color (a* value). However, no effect was found on pH, L and b* values. On the other hand, the WHC and sausage texture were also significantly (P≤0.05) affected by soybean oil addition without altering pH and color. The highest addition level (20%) for both elephant foot yam flour and soybean oil showed a firm and compact beef sausage micro-structure with small pores. The highest fat and crude fiber content were also found in this group (20% addition level) and the sensory attributes (texture, aroma and taste) of the former group were comparable with the group with lowest addition level (10%). Therefore, elephant foot yam flour can be used as filler for producing both reduced-fat and typical beef sausage.

Abstract

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a toxic compound of organic pollutants that is very persistent in the environment. This compound can accumulate in the body through contaminated food and can cause various adverse effects on human health. The purpose of this study was to observe the effect of casein tablets made from goat milk yogurt on Liver histopathological profile, residual TCDD and malondialdehyde (MDA) levels in broiler chicken exposed to 50 ng/mL TCDD. A total of 18 male broiler chickens aged 3 weeks were used in this study and were divided into 3 experimental groups based on a completely randomized design (CRD): 1 (negative control group), 2 (positive control group), 3 (therapeutic group) which were administered by 750 mg of casein from goat milk yogurt for 21 days. TCDD residue and MDA levels in the liver were measured using a UV-Vis spectrophotometer and thiobarbituric acid reactive substances test, respectively. The liver histopathological profile was observed using hematoxylin-eosin staining. The results showed that the administration of casein tablets decreased the level of TCDD residue and MDA by 5.75% and 43.74%, respectively. Moreover, the liver histopathological profile of the therapeutic group was better than that of the positive control group. It is suggested that casein tablet made from goat milk yogurt possesses anti-dioxin and antioxidant capacities.
