Effectiveness of Lactic Acid Filtrate Products Shrimp Paste against the Quality Characteristics of the Fresh Fresh Fish (Dasyatis Kuhlii) from the Belawan Fish Auction Place (TPI)

Introduction

The fishing industry plays a vital role in the economy of many countries, with various types of fish being caught and sold in the market. One of the types of fish that has high economic value is the stingray (Dasyatis Kuhlii). However, the handling of this fish when on the ship is often less attention, resulting in the condition of the fish becoming not fresh when it arrives at the port. This study aims to evaluate the effect of lactic acid filtrate from shrimp paste products in maintaining the quality characteristics of stingrays.

Background

Stingrays are one of the most valuable types of fish in the fishing industry, with high demand in the market. However, the handling of this fish is often neglected, resulting in the condition of the fish becoming not fresh when it arrives at the port. This can lead to a decrease in the quality of the fish, making it less desirable for consumers. The use of lactic acid filtrate from shrimp paste products has been shown to have potential in maintaining the quality of fish. Lactic acid bacteria (BAL) isolated from shrimp paste have been used to improve the quality of fish by reducing the pH and total volatile base nitrogen (TVBN) levels.

Methodology

This study was conducted from August to October 2022, using lactic acid bacteria (BAL) isolated from shrimp paste. The BAL was stored for seven days at 25-27 ºC, and observations were made on the 2nd, 4th, and 7th days. The pH and TVBN levels were measured, as well as the total plate count (TPC) of the fish. The results of the study showed variations in pH levels, ranging from 7.99 to 9.17, and TVBN values ranging from 627.33 MGN/100 g to 1052.16 MGN/100 g. The TPC showed a significant number, ranging from 3.86 x 10^7 cfu/ml to 6.788 x 10^8 cfu/ml.

Results

The results of the study showed that the effect of lactic acid filtrate from shrimp paste products in maintaining the quality of stingrays was less effective at room temperature. This indicates the need for further handling to increase the storage of stingrays, especially after arrest. The study also showed that the use of lactic acid filtrate has the potential to improve fish quality, but its effect is very dependent on storage temperatures and environmental conditions.

Analysis of Research Results

Based on the results of the test, it can be analyzed that high stingrays have the potential to reduce the taste and quality of the meat. In addition, the increasing TVBN level indicates a worse decay process. The higher the TVBN value, the lower the quality of the fish. Meanwhile, high TPC shows the growth of uncontrolled microorganisms, which can potentially endanger the health of consumers if the fish are consumed. These results indicate that post-pyudous handling should be considered seriously to maintain product quality.

Recommendations for Handling Stingrays

Based on these findings, it is recommended that fishermen and fisheries industry players pay more attention to the techniques of handling and storing stingrays after being captured. In addition to the use of lactic acid filtrate, other methods such as fast cooling or the use of natural preservatives can also be applied to maintain the freshness and quality of stingrays. The implementation of better handling techniques is expected to increase the selling value of stingrays on the market and have a positive impact on fishermen's income and food security. Awareness of the importance of maintaining fish quality must be a priority at every stage, ranging from fishing to distribution to consumers.

Conclusion

In conclusion, this study has shown that the use of lactic acid filtrate from shrimp paste products has the potential to improve the quality of stingrays. However, the effect of this method is very dependent on storage temperatures and environmental conditions. Therefore, it is recommended that fishermen and fisheries industry players pay more attention to the techniques of handling and storing stingrays after being captured. The implementation of better handling techniques is expected to increase the selling value of stingrays on the market and have a positive impact on fishermen's income and food security.

Future Research Directions

Future research directions include the study of the effect of lactic acid filtrate on other types of fish, as well as the development of new methods for maintaining the quality of fish. Additionally, the study of the impact of handling techniques on the quality of fish is also recommended. By conducting further research in this area, it is expected that the quality of fish can be improved, and the income of fishermen can be increased.

Limitations of the Study

This study has several limitations, including the use of a small sample size and the lack of control over environmental conditions. Additionally, the study was conducted in a laboratory setting, which may not reflect the actual conditions of the fishing industry. Therefore, further research is needed to confirm the findings of this study and to develop new methods for maintaining the quality of fish.

Frequently Asked Questions (FAQs) about the Effectiveness of Lactic Acid Filtrate Products Shrimp Paste against the Quality Characteristics of the Fresh Fresh Fish (Dasyatis Kuhlii) from the Belawan Fish Auction Place (TPI)

Q: What is the purpose of this study?

A: The purpose of this study is to evaluate the effect of lactic acid filtrate from shrimp paste products in maintaining the quality characteristics of stingrays (Dasyatis Kuhlii) from the Belawan Fish Auction Place (TPI).

Q: What are the quality characteristics of stingrays that were evaluated in this study?

A: The quality characteristics of stingrays that were evaluated in this study include pH, total volatile base nitrogen (TVBN), and total plate count (TPC).

Q: What is the significance of pH in the quality of fish?

A: pH is an important factor in the quality of fish, as it affects the growth of microorganisms and the development of off-flavors and off-odors. A pH level of 7.99 to 9.17 was observed in this study, which is within the acceptable range for fish quality.

Q: What is the significance of TVBN in the quality of fish?

A: TVBN is an indicator of the spoilage of fish, as it increases with the growth of microorganisms. A TVBN value of 627.33 MGN/100 g to 1052.16 MGN/100 g was observed in this study, which indicates a moderate level of spoilage.
