The Effect Of Storage Time On Free Fatty Acids In CPO And RBDPO At PT.Smart Tbk

by ADMIN 80 views

Introduction

Crude palm oil (CPO) and refined, bleached, and deodorized palm oil (RBDPO) are two types of palm oil that are widely used in various industries, including food, cosmetics, and pharmaceuticals. The quality of these oils is crucial in determining their shelf life and economic value. One of the key factors that affect the quality of palm oil is the level of free fatty acids (FFA). In this study, we investigate the effect of storage time on FFA levels in CPO and RBDPO at PT. Smart Tbk.

Background

Palm oil is a complex mixture of triglycerides, which are composed of glycerol and fatty acid chains. During storage, palm oil can undergo various chemical reactions, including hydrolysis, oxidation, and polymerization. Hydrolysis is a chemical reaction in which water reacts with fat, producing fatty acids and glycerol. This reaction can occur naturally in palm oil, especially when it is stored for an extended period. The level of FFA in palm oil is an important indicator of its quality and shelf life.

Research Methodology

In this study, we used alkalimetric titration with NaOH to determine the level of FFA in CPO and RBDPO at PT. Smart Tbk. The samples were collected on the first day, third day, sixth day, and twelfth day of storage. The results were then analyzed to determine the effect of storage time on FFA levels.

Results

The results of the study are presented in the following table:

Sample Day 1 Day 3 Day 6 Day 12
CPO 4.11% 4.51% 5.01% 5.23%
RBDPO 0.0436% 0.0523% 0.1025% 0.1234%

As shown in the table, the level of FFA in CPO increased from 4.11% on the first day to 5.01% on the sixth day. Similarly, the level of FFA in RBDPO increased from 0.0436% on the first day to 0.1025% on the sixth day. These results indicate that the hydrolysis process occurs along with the length of storage, which causes an increase in FFA levels in both types of oil.

Discussion

The increase in FFA levels in CPO and RBDPO can be explained by the chemical process of hydrolysis. Hydrolysis is a chemical reaction in which water reacts with fat, producing fatty acids and glycerol. In the context of storage, the longer the oil is stored, the more likely the occurrence of this reaction, especially if the storage conditions are not ideal, such as high temperature and humidity.

High levels of FFA in oil can affect the quality and shelf life of the oil. For example, high FFA levels can cause oil to experience rancid taste and have the potential to reduce its economic value. Therefore, it is essential for oil producers such as PT. Smart Tbk to supervise and manage oil storage time effectively, in order to maintain product quality.

Conclusion

This study shows that the shelf life has a significant effect on FFA levels in CPO and RBDPO. In the oil processing industry, an understanding of the storage time effect is very important to ensure the quality of the final product and customer satisfaction. Thus, good storage management can be the key to increasing the competitiveness of products in the market.

Recommendations

Based on the findings of this study, the following recommendations are made:

  1. Regular monitoring of FFA levels: Oil producers should regularly monitor FFA levels in their products to ensure that they are within the acceptable limits.
  2. Effective storage management: Oil producers should implement effective storage management practices, such as controlling temperature and humidity, to prevent the occurrence of hydrolysis.
  3. Proper handling and transportation: Oil producers should ensure that their products are handled and transported properly to prevent damage and contamination.
  4. Quality control: Oil producers should implement quality control measures to ensure that their products meet the required standards.

Limitations

This study has several limitations, including:

  1. Limited sample size: The sample size used in this study was limited, which may not be representative of the entire population.
  2. Short storage period: The storage period used in this study was short, which may not be representative of the long-term effects of storage on FFA levels.
  3. Limited analysis: The analysis used in this study was limited to FFA levels, which may not be representative of other quality parameters.

Future Research Directions

This study provides several avenues for future research, including:

  1. Investigating the effects of storage conditions: Future studies should investigate the effects of different storage conditions, such as temperature and humidity, on FFA levels.
  2. Examining the effects of storage time on other quality parameters: Future studies should examine the effects of storage time on other quality parameters, such as peroxide value and iodine value.
  3. Developing predictive models: Future studies should develop predictive models to predict FFA levels based on storage time and other factors.
