Abstract

Due to the growing interest in the production and consumption of wild boar meat, the quality attributes of meat products should be well established. To characterize the quality of wild boar cross meat, two males and two females reared in the same environment were slaughtered at an average of one year of age, and meat samples were was collected and analyzed for different parameters such as for moisture, pH value, protein, fat, iron, phosphorous, calcium, water holding capacity through the measure of cooking loss. Data obtained for live body weight, carcass biochemical characteristics, and meat quality traits were submitted to one-way analysis of variance (ANOVA) using a general linear model (uni-variate) in Statistical Package for Social Sciences (SPSS) computer program and the level of significance was determined observing the probability value (p) obtained through ANOVA of respective traits. To study the association among nutritive values and body parts, Pearson’s correlation coefficients were determined using in Statistical Package for Social Sciences (SPSS) computer program. The pH values were found to be in the range of 5.78 to 5.90. Moisture, total ash, fat, and protein contents were observed to be in the range of 71.38 to 73.57 %, 0.89 to 1.10 %, 4.34 to 5.54 %, and 16.73 to 18.84 % respectively. Iron, phosphorous, and calcium content were found to be in the range of 1.94 to 2.94 mg/100g, 20.17 to 37.57 mg/100g, and 170.68 to 190.88 mg/100g respectively whereas cooking loss was in the range of 31.59 to 26.88 %. Sensory evaluation of meat samples was examined by a group of panelists according to the hedonic rating test. The consumer preference was similar to both types of meat samples (male and female). The overall acceptance; however, were higher in female samples than in male samples due to boar taint evident during the cooking or eating of pork derived from non-castrated male pigs once they reach puberty. The comparison of wild crosses among available commercial pigs and indigenous pigs is warranted for further studies with an appropriate and defined production system to obtain lean meat as per the consumer preferences which could be extensively used in commercial pig production to provide high-quality pork.

Abstract

(1) Background: It Is recommended that children consume adequate amount of vegetables. However, the problem still remained in every single family and community. Many studies to find out its causes have been done. Unfortunately, most of them were conducted on parents only. Little is known from children’s own perspective. Children’s perspective is important to help adults in choosing vegetables for the children. Thus, this study aimed to explore children’s opinion on vegetables consumption.; (2) Methods: Qualitative design was employed. Samples were selected using purposive technique sampling. Nine participants aged 6-12 years were interviewed in a focus group discussion. Data were analysed using qualitative data analysis by Miles and Huberman.; (3) Results: The FGD indicates three themes: why kids dislike vegetables, sort of vegetables which kids love to consume, reasons why kids want to eat vegetables.; (4) Conclusions: Health education and involving children in their own food preparation is promising way to improve vegetables intake. Further research is to develop a new form of health education and a program in which children are involved to choose and prepare their own vegetables.

Abstract

Brazilin in sappan is sensitive to pH, which make it possible as indicator of food quality. This research aimed to investigate performance of sappan extract as colorant for indicator label applied in chicken meat packaging. The samples were stored at room and refrigerator temperature. They were then tested for color change of label RGB (Red Green Blue), pH and TVB-N (Total Volatile Base-Nitrogen) of the meat. Data were analyzed using ANOVA at significant level of 5%. Indicator label showed the reduced RGB during storage, while pH and TVB-N increased. In case of room temperature, the color change into pink occurred in day 3 with pH 6.72 and TVB-N 1.84 mg N/100g. Meanwhile, for samples at refrigerator temperature, the label color turned into pink in day 6, with pH 6.56 and TVB-N 2.09 mg N/100g. In this regard, indicator label could detect the depletion of chicken meat quality as indicated by color shift from yellow to pink when pH and TVB-N were at critical value. This result provides significant output for development of sappan extract for indicator of meat spoilage.

Abstract

Topics protection of catchment area relating to land use to support sustainability and environmental capacity is an interesting topic to be discussed scientifically. The increasing frequency of floods, droughts, landslides, and water crises are recently showed that the management of watersheds (DAS) has not been optimal. The Kineros Model for predicting the effect of land use on the surface run-off need to be improve in application. This paper has shown that the protection of natural ecosystems has a better impact than infrastructure development, especially about preventing inundation due to high surface runoff. This journal will strengthen the need for watershed-scale erosion prediction analysis because of its ability to define strategic areas of policy intervention to enable policymakers and the community to carry out recovery programs/activities more effectively and focused. The accuracy of determining the location of the policy has an impact on cost, time, and energy efficiency. Spatial calculation/analysis models combined with social and economic approaches will create a balanced and integrated sustainable development. The reviewer suggests a realistic combination of approaches, which combines the spatial aspects and technocratic calculations aspects of economic instruments that become balanced in a multidisciplinary concept.

Abstract

Duck egg is known to have an unpleasant fishy odor which often becomes a factor reducing its acceptance in public. This odor is resulted from lipid oxidation which can be avoided by using an antioxidant. This study was aimed at assessing the effects of the inclusion of star gooseberry (Sauropus androgynus) dried leaf extract in ration on egg organoleptic quality of local duck. The study was conducted in a completely randomized design with 4 treatments and 4 replicates. Sensory test by 60 semi-trained panelists and hedonic quality and hedonic tests were conducted. Data were subjected to a Kruskal-Wallis test. Results showed that treatments gave significant effects (P <0.05) on aroma (hedonic), yolk color, and aroma (hedonic quality). It was concluded that the inclusion of star gooseberry dried leaf extract by 1,5% in ration improved the quality of egg yolk color, egg aroma, and consumers’ preference. A further study on the effects of DSGLE on meat quality and protein digestibility in ducks was recommended.

Abstract

One of the sources of animal protein for the community can be obtained from quail eggs. Quail eggs have nutritional value that is not inferior to other poultry eggs. Feed is one of the factors that can affect egg quality. Coriander is a spice that contains essential oils that are beneficial for the body when consumed. So it is hoped that the presence of this essential oil can help improve livestock growth and produce quality quail eggs sensory. This study aimed to examine the effect of giving coriander flour to quail feed on the sensory quality of eggs. The study was conducted for 30 days. The livestock used were Japanese quail aged 30 days with 100 heads. The feed used is commercial feed and additional coriander flour. The design used was a completely randomized design with 4 treatments and 5 replications for each unit of 5 birds with treatment R0 = commercial feed +0% coriander flour, R1 = commercial feed + 0.5% coriander flour, R2 = commercial feed + 1% coriander flour, R3 = commercial feed + 1.5% coriander flour. Data were analyzed using Kruskall Wallis and Duncan's multiple range test. The results showed that the administration of coriander flour had a significant effect (P<0.05) on the hedonic test of egg white color and texture hedonic quality test, while for the egg yolk color, taste, aroma variables were not significantly different (P>0.05). This study concludes that organoleptic administration of 1% coriander flour can increase the panelists' preference for egg whites and improve the texture of quail eggs.

Abstract

Bacteriocin was bacterial metabolite that have antimicrobial properties, so it had the potential to be used as food bio preservatives. Bacteriocin was produced by lactic acid bacteria (LAB), one of the sources of which was from smoked fish products. Some regions in Indonesia produce various types of smoked fish from various types of fish, which were thought to contain bacteriocin-producing lactic acid; one of them was giant cathfish (Arius thalassinus). This study aims to obtain LAB isolates that have strong antimicrobial activity and have the potential to produce bacteriocin-like from smoked giant catfish (Arius thalassinus). The research method used an experimental method that analyzed descriptively. Based on the results, there were 15 isolates LAB isolated from smoked giant catfish. Three selected isolates showed strong antimicrobial activity inhibiting E. coli and S. aureus bacteria, and the most effective inhibiting Salmonella sp. One selected LAB isolates identified Pediococcus acidilactici suspected to produce pediocin bacteriocin-like, while the other two isolates identified Lactobacillus plantarum sp 1 and Lactobacillus plantarum sp 2 which suspected to produce plantaricin bacteriocin. Bacteriocin from the three isolates of LAB had characteristics stable to temperatures up to 121oC, stable in pH range 2-6, and bacteriocin activity increased with the addition of SDS (Sodium Dodecyl Sulfate) and EDTA (Ethylenediaminetetraacetic acid) surfactants. The conclusion was that the bacteriocin produced was stable at high temperature, low pH, and resistence in the presence of surfactants, so it had the potential to be developed as biopreservatives material in preserving fish-based foods
