Detection of Borax Content with Turmeric (Curcuma Longa Linn.) in Meatball Snacks in the Pekenan Area

Meatball snacks are one of the most popular culinary delights in Indonesia, nutrition in the form of animal protein which is important for the growth and development of our bodies can be obtained from consuming meatballs, but what is worrying is that there are irresponsible sellers who are not responsible for maintaining consumer health, namely adding borax as a food additive so that meatballs last longer and are more chewy, the use of borax in food can cause health problems. The Pekenan Pasar Sore area is an area that is one of the places where meatball sellers sell their wares, therefore the author conducted a study on the detection of borax content with turmeric filtrate in meatball snacks sold in the Pekenan Pasar Sore area, with the aim of finding out whether or not there are meatball sellers in the area who add borax to the ingredients for making their meatballs. This research was conducted from June to August 2024. This type of research is qualitative. The meatball samples in this study were meatballs from meatball traders in the Pekenan Pasar Sore area, Beringin District, totaling 12 traders taken by total sampling. Organoleptic tests and detection of borax content were carried out on meatball samples with turmeric filtrate. The data were analyzed descriptively. From the results of the study, it was found that the physical characteristics of the A-L meatball sample included having a natural meat aroma, gray color, and a texture that was not too chewy. And the results of the borax test on the A-L meatball sample with turmeric filtrate produced a yellow color. So from these results it shows that the A-L meatball sample sold by meatball sellers in the Pekenan Pasar Sore area does not contain borax.

Analysis Pork Contamination in Beef Meatballs through Polymerase Chain Reaction in Palu City

The need for halal products is essential, particularly among various processed beef products like meatballs, which are popular among nearly the entire community. These products are susceptible to issues of meat counterfeiting for greater economic gain. This study aims to determine the smallest DNA concentration that can still be detected and to assess whether there is any pork contamination in meatballs circulating in Palu City using Polymerase Chain Reaction (PCR). This test uses four DNA samples obtained from fresh meat to test the specificity of the primer: wild boar, rat, and goat DNA samples as comparisons, and pig DNA as a positive control. The presence of DNA bands in the agarose gel electrophoresis visualization results indicates that DNA amplification has occurred, meaning that the sample can be detected. The analysis results showed that the primer used (Cyt-b) had good specificity for detecting pork DNA, while the absolute pork DNA concentration of 0.01 ng/µL and the reference meatball DNA with a concentration of 0.01% are the smallest limits that can still be detected using PCR. Of the four meatball samples from Palu City, one sample produced a DNA band, indicating that the sample contains or is contaminated with pig DNA. This method is valid as it meets the specificity test and demonstrates a good detection limit.

Identifikasi Bakteri Salmonella sp pada Bakso Ayam yang Dijual di Pasar Tradisional Kecamatan Denpasar Selatan

Indonesia is a country that is rich in various kinds of food products, one of which is meatballs. Meatballs are food products made from crushed meat, mixed with flour and some complementary spices, formed into rounds, and boiled. Meatballs can be found in almost all cities in Indonesia because this product is much- loved by the community, one of which can be found in traditional markets in the South Denpasar district. The market is very vulnerable and has quite a high risk of pathogenic microbial contamination. Improper processing of meatballs and low sanitation of the environment where they sell and personal hygiene of traders can increase bacterial contamination. This study aims to determine the contamination of Salmonella sp bacteria in chicken meatballs and the application of sanitation and hygiene to chicken meatballs sold in traditional markets in the South Denpasar district. This study used survey methods and sampling techniques with saturated sampling methods. The total samples used in this study were 10 samples which were tested with SSA media, gram staining, and TSIA test. The data obtained were presented in the form of tables and pictures and analyzed descriptively. The results showed that 7 samples of chicken meatballs sold in traditional markets in the South Denpasar District contained Salmonella sp. These results indicate that chicken meatballs sold at traditional markets in South Denpasar District have not met the requirements of the Food and Drug Supervisory Agency Regulation No. 13 of 2019 concerning the maximum limit of microbial contamination in processed food, Salmonella sp. in meatballs is negative/25g and some traders have not implemented good hygiene and sanitation practices.

Identification of Borax in Meatball Skewer Snacks in East Lombok

Meatballs are a processed meat-based food commonly processed by adding chemical preservatives. Many reports find the usage of borax as the chemical preservative in meatballs sold in large markets on Lombok Island. However, the use of borax in the type of meatball consumed as snacks called skewered meatballs has not been identified thoroughly in East Lombok. This study aimed to identify borax in skewered meatballs in East Lombok qualitatively by curcumin paper test and flame test colors using sodium tetraborate as standard. The result showed that 4 samples confirmed positive for borax through the curcumin paper test. Two of those four samples showed the same flame color as standard corresponding to the presence of borax as a preservative in skewered meatballs tested. These results indicate that the curcumin paper test and flame color test were compatible in identifying borax in skewered meatball samples qualitatively.

Bacteria Contaminants in Meatballs Sold in the Market Padang City Raya

Meatballs are a processed meat product that has high nutrition. The maximum shelf life for meatballs made from meat is 1 day (12 hours). Storing meat foods at inappropriate temperatures, such as room temperature, greatly facilitates the growth of microbes. The marketplace for meatballs in traditional markets in the city of Padang is still sold on the streets at open-air temperatures without using sufficient refrigeration. The possibility of contamination with microorganisms is very large. This research aims to determine the suitability and quality of meatballs sold at Pasar Raya Padang City by examining the Total Plate Count (TPC) and identifying the types of bacteria that contaminate meatballs sold at Pasar Raya Padang City. The research results showed that the amount of microbial contamination in meatballs varied, namely 1.9x10 6, 7.5x10 6, 5.6x10 6, 1.8x10 6, 8.6x10 6, and 9.2x10 6. The results of this study showed that the meatball samples had microbial contamination greater than 10 5 CFU/gr or did not meet SNI standards. Based on macroscopic and microscopic morphological identification as well as biochemical reactions, all isolates were classified as bacteria from the genus Bacillus

Are online meatball restaurants in Indonesia committed to their declared Halal label?

Background and Aim: Halal restaurants participating in online food delivery services do not require halal certification. The Halal status of products through the Halal logo provides the consumer with information on the basis of which he decides to buy. Online transactions involve potential risks related to online processes, payment methods, and product quality. The aim of this study was to determine whether a declared Halal label is in accordance with the business processes implemented. Materials and Methods: Halal authentication of Gofood's meatball partner products in Yogyakarta and Solo Raya determined the incompatibility of meatball ingredients. Sixty meatball samples were collected from Yogyakarta and 30 samples from Solo Raya. Halal certification test was carried out using the thermal cycle polymerase chain reaction method at Universitas Gadjah Mada Animal Husbandry Laboratory and the results were used to identify pork contamination in meatballs. The addition of pork or pork meatballs was used as a control. Results: Eight meatball restaurants in the Solo Raya and Yogyakarta areas were found to be contaminated with pig DNA. The results of the tracing materials and processes, i.e., the grinding stage, are critical because all samples were supposed to be made from beef. It is known from interviews that contamination with pig DNA at the milling stage was accidental. Conclusion: Restaurants that sell meatballs are committed to adhering to product labels that are 91.1% safe from pork contamination. The Halal and original beef labels were in accordance with their statements. This study highlights the concept of Halal authentication with traceability to overcome pork contamination in meat products. Keywords: halal authentication, halal supply chain, online food delivery, traceability.

Identification of Formalin in Meatball Sold at Palopo City Food stalls using Schryver Method Approach

Formalin, a solution containing 30-50% formaldehyde gas (CH2O), finds applications in various sectors such as corpse preservation, disinfection, and the production of plastics and anti-foaming agents. Despite its industrial benefits, formalin is often misused as a preservative in the food industry, particularly in perishable items like meatballs. This research employs a descriptive method to provide an overview of formaldehyde identification in meatballs. Ten meatball samples were collected from permanent stalls in Palopo City for analysis. Laboratory tests conducted qualitatively using the Test Kit method revealed negative results (-) for formalin content in all samples. No color changes were observed in the tested meatballs, indicating the absence of formalin.

Investigation of Biofilm Production and Determination of Antibiotic Resistance Profile of Staphylococcus aureus Isolated from Ground Beef and Meatballs

Staphylococcus aureus (S. aureus) is bacterium that threatens public health because it causes infections and food intoxication. For this reason, within the scope of this study, it was aimed to determine the presence of S. aureus, antibiotic resistance profiles, and biofilm formation in ground beef and meatball samples consumed in Amasya. In the study, 60 meat samples purchased from Amasya were used as material. First, conventional culture technique and PCR testing were used for the isolation of S. aureus. Secondly, antibiotic resistance profiles of the S. aureus were analyzed by disc diffusion. Finally, biofilm production of the S. aureus was analyzed phenotypically by the microtiter plate method and genotypically by PCR. Through the study, we identified 58 S. aureus isolates that were confirmed phenotypically and genotypically. Disc diffusion results showed that all S. aureus were sensitive to imipenem and piperacillin-tazobactam, but resistant to methicillin 43.10% (25/58), erythromycin 41.37 % (24/58), penicillin 58.62% (34/58), gentamicin 10.34% (6/58), chloramphenicol 17.24% (10/58), tobramycin 6.89% (4/58), and levofloxacin 1.72% (1/58). Biofilm production was determined as 58.62% (34/58) in the microtiter plate. In the PCR analysis, the icaA or icaD gene of a total of 4 (6.89%) different isolates was evaluated as positive. As a result, the presence of antibiotic-resistant S. aureus in ground beef and meatballs and the production of biofilm by the bacteria pose a potential risk. Therefore, it is important for human health to take the necessary precautions to reduce the risk of S. aureus contamination during the processing, and transportation.

Comparing application methods of reishi mushroom (Ganoderma lucidum) extract in deep-fried meatballs: impact on heterocyclic aromatic amine formation.

The present research was conducted to investigate the impact of reishi mushroom extract (RME) on the formation of heterocyclic aromatic amines (HAAs) in meatballs. Sample preparations involved applying RME using either the spreading or addition method, with varying concentrations (0%, 0.25%, 0.5%, and 1% of RME), followed by deep-frying at temperatures of 150 and 190 °C for 3 min. The types and levels of HAAs varied based on the frying temperature, method of extract application, and the extract concentration. Notably, total HAA contents increased with rising the frying temperature (P < 0.01) and varied from undetectable levels to 4.91 ng g-1 across all analyzed meatballs. The addition method was more effective than the spreading method (P < 0.01), and among the concentrations tested 0.25% RME exhibited the highest efficacy in reducing total HAAs (P < 0.05). Furthermore, the addition method inhibited lipid oxidation more efficiently compared to the surface spreading method (P < 0.05). This study demonstrated that RME had mitigating effects on HAAs depending on the concentration and frying conditions in deep-fried meatball samples. © 2024 The Author(s).

Effect of Olive Oil Hydrogel as a Fat Replacer in Beef Meatballs.

Meat and meat products are essential sources of dietary saturated fatty acids. However, excessive consumption of meat and meat products may be harmful to human health. The study evaluates the effect of fat replacement with hydrogels (olive oil in water emulsions gelled by gelatine) in meatballs. The effect of replacing fat with different ratios of hydrogel (control, 25 (F25), 50 (F50), 75 (F75) and 100 % (F100)) on the chemical (fatty acids and thiobarbituric acid reactive substances (TBARS)) and physical (cooking loss, diameter reduction, fat retention, water retention, colour and texture analysis) characteristics of the meatballs were analyzed. The fat content of raw meatball samples was reduced from (31.2±2.2) to (10.5±0.4) % in the sample with the highest fat substitution (F100). The energy levels of the F100 samples were almost 56 % lower than of the control group. Monounsaturated fatty acids (MUFAs) represented the dominant group in all substitution rates of the meatballs, followed by saturated fatty acids (SFAs) and finally polyunsaturated fatty acids (PUFAs). Among the raw meatball samples, the highest oxidation occurred in the F50 and F100 groups. However, it was determined that the difference between F25 and F75 and the difference between control and F75 were not statistically significant (p˃0.05). When the cooked samples were compared, the highest thiobarbituric acid (TBA) value was found in the F50 sample, followed by the F100 and F75 samples. The difference between the mean values of springiness and cohesiveness of the samples was not significant (p˃0.05). The hardness value of samples decreased significantly (p˂0.001) with >75 % fat replacement. It can be concluded that the oil replacement rate that may satisfy consumer demand without impairing the product technological and chemical quality should be <75 %. As the fat replacement ratio increases, the SFA content of cooked meatballs decreases, while the MUFA and PUFA contents increase. Considering the positive effects of reducing the intake of SFAs and increasing the intake of unsaturated fatty acids on non-communicable diseases such as cardiovascular diseases, fat replacement in meatballs is important for future developments.

Sensitivity of commercial rapid test kit to pork contamination in processed foods

Guaranteeing halal products has now become a necessity, especially for food products. This is intended to ensure that the food produced is not contaminated with non-halal ingredients, including pork. Pork contamination in processed meat foods such as meatballs is still often found. Various tests can be done to detect the presence of pork in processed foods. One of them is a rapid test using the LFIA method. This test is widely used because it is more efficient, economical, and easy to prepare samples. A rapid pork contamination test kit (XEMA) has been circulating in Indonesia. In the research, the sensitivity of this rapid test kit was tested on processed meat foods with various concentrations of pork and variations in the main ingredients. The color test shows that the simulated samples of beef meatballs without added pork are dark greyish white, as are the simulated samples with concentrations of 1% and 10%. Meanwhile, samples with concentrations of 20% and 40% have a paler color. Meanwhile, there was no significant difference in the variation in pork concentration in meatballs with the main ingredients of chicken and fish. For smell and texture, there were no significant differences in the simulated samples, both the control and samples with varying concentrations. From testing, it is known that the test kit can detect the presence of pork up to a concentration of 10% in samples, with the main ingredients being beef, chicken, or fish. These results indicate that this rapid test kit can well detect pork contamination in processed food samples.

This study aims to determine the effect of heating time in the combustion process on Staphylococcus aureus contamination in grilled meatballs. A total of 9 samples of meatballs obtained from 3 sellers of grilled meatballs were divided into 3 treatments, namely burning at temperatures ranging from 56˚C-59˚C for 1 minute, 3 minutes, and 5 minutes, with 3 repetitions. Determination of the number of microbes was carried out using the Total Plate Count (TPC) method. The research data were analyzed using a two-way ANOVA analysis of variance followed by Duncan's test. The results showed that the duration of burning affected the amount of Staphylococcus aureus contamination in grilled meatballs. The best combustion was shown at 5 minutes, with a microbial count of 3.6 × 101 CUF/g. The results of the analysis of variance (ANOVA) showed that there was a significant difference (P0.05) in the average value of Staphylococcus aureus microbial contamination in grilled meatballs given treatment. Based on the calculation results, it can be concluded that 5 minutes of burning time is the most effective for decontaminating the amount of Staphylococcus aureus microbial contamination in grilled meatballs.

Development of real-time polymerase chain reaction for analysis of rat meat (Bandicota bengalensis) in beef meatballs for halal authentication.

Consumer awareness of food adulteration is increasing nowadays. Motivated by economic gain, unethical meat producers try to blend halal meat such as beef with non-halal meat like rat meat (RM). This study aims to develop a real-time polymerase chain reaction (RT-PCR) analysis method to analyze the presence of RM in beef meatballs. This research was carried out in the following stages: primer design, DNA isolation, analysis of DNA isolates, the optimization of primer annealing temperature, primer specificity test, sensitivity, and repeatability. The validated RT-PCR method was then used to analyze the marketed meatball samples. The result showed that the designed primer targeting on ND2 gene set rat mt-DNA (forward: ACTCCATATCTCTCACCATATTTCC; reverse: GGGTTAGGGTACTTAGGATTGTTAG), had good specificity at an optimal annealing temperature of 56.3oC over the other eight species. The developed RT-PCR method produces a limit detection value of 195.31 pg, coefficient of determination (R 2) for linearity of 0.983, amplification efficiency (E) of 100%, and CV value for amplification response of 1.8%. The result showed that the developed RT-PCR method did not detect the presence of RM DNA in eight marketed beef meatball samples. The developed method meets the acceptance criteria for RT-PCR and can be used as a halal authentication method to identify the presence of RM in beef meatballs.

Quality Evaluation of Buffalo Meatballs Produced at Different Comminution Process Temperatures

Buffalo meatballs were formulated and the effects of different comminution temperatures on the quality (cooking yield, water holding capacity (WHC), protein, texture, colour, and sensory) were evaluated. During the mixing of ingredients, the comminution temperature was adjusted using different types of water which were ice (0°C), ice water (4°C), cold water (10°C), room temperature water (22°C), and warm water (32°C). Following comminution for 3 minutes, the temperatures of the batters were recorded at 14, 25, 25, 29, and 27°C, respectively. The comminution took a total of 15 minutes had produced batters with similar final temperatures (ranging from 36 to 38°C), except ice temperature mixing (28°C). Cold water meatballs produced the highest cooking yield but significantly the lowest (P&lt;0.05) water-holding capacity. The colour of the cold water meatball shows significantly (P&lt;0.05) the highest L* (lightness), significantly (P&gt;0.05) the lowest a* (redness), and the lowest b* (yellowness) values. While the textures (hardness, cohesiveness, gumminess, chewiness, and springiness) of all meatballs were similar (P&gt;0.05). All meatball samples had nearly similar soluble protein concentrations (0.97 to 1.06 ug/ml) but ice water meatballs had the highest (P&lt;0.05). The panellists gave all the meatballs a score ranging from 6.32 to 6.98, with ice meatballs receiving the highest mean score (6.98) acceptability score (P&gt;0.05). In conclusion, comminuted buffalo meatballs can be produced using either ice, ice water, cold water, room temperature water, or warm water without affecting their quality. However, ice is suggested for safety purposes against microbial growth during processing.
