The Effect of pH and the Duration of Hydrolysis on the Manufacture of Glucose Syrup from Tapioca by Acid Hydrolysis

Introduction

The production of glucose syrup from tapioca is a crucial process in the food and beverage industry, with applications in various products such as soft drinks, baked goods, and confectionery. The process involves acid hydrolysis, a chemical reaction that breaks down starch into simple sugars. However, the quality of the resulting glucose syrup is heavily dependent on the pH and duration of hydrolysis. This study aims to investigate the effect of pH and hydrolysis time on the quality of glucose syrup produced from tapioca using acid hydrolysis.

Materials and Methods

This study employed the Factorial Complete Random Design (RAL) method with 2 factors: pH and hydrolysis time. The pH factor had 4 levels: pH 1.00, pH 1.50, pH 2.00, and pH 2.50. The hydrolysis time factor also had 4 levels: 2 hours, 2.5 hours, 3 hours, and 3.5 hours. This resulted in 16 combinations of treatments tested.

Results

The results of this study showed that pH had a significant effect on total dissolved solids (TSS) and glucose levels. The lower the pH, the higher the TSS and glucose levels. This indicates that more acidic pH accelerates the hydrolysis process, resulting in more starch breaking down into sugar.

Furthermore, hydrolysis time also had a significant effect on glucose, TSS, degrees of thickness, and organoleptic colors. The longer the hydrolysis time, the higher the glucose levels, TSS, and degrees of thickness. This is because the longer the hydrolysis time, the more starch breaks down into sugar.

Discussion

The combination of pH treatment and hydrolysis time had a significant effect on glucose levels, but had no significant effect on TSS, degrees of thickness, and organoleptic colors. This suggests that pH and hydrolysis time interact to affect the quality of glucose syrup.

The Importance of this Research

This study provides valuable information for the food and beverage industry that uses glucose syrup as a raw material. The results of this study can be used to determine the optimum condition of pH and hydrolysis time in the process of making glucose syrup, resulting in products with good quality and consistent quality.

Further Analysis

This research can be continued by testing the effect of other variables such as acid types, acid concentrations, and hydrolysis temperatures. Additionally, the results of this study can be used to develop the Glucose Syrup Quality Prediction Model based on pH parameters and hydrolysis time.

Conclusion

By understanding the effect of pH and the duration of hydrolysis in the process of making glucose syrup from tapioca, we can optimize the production process and produce high-quality products. This study provides valuable insights for the food and beverage industry, and can be used as a reference for future research in this field.

Recommendations

Based on the results of this study, the following recommendations can be made:

The pH level should be maintained at a lower level (pH 1.00) to achieve higher TSS and glucose levels.
The hydrolysis time should be extended to 3.5 hours to achieve higher glucose levels, TSS, and degrees of thickness.
The combination of pH treatment and hydrolysis time should be considered when determining the optimum condition for glucose syrup production.

Future Research Directions

This study can be continued by investigating the effect of other variables such as acid types, acid concentrations, and hydrolysis temperatures on the quality of glucose syrup. Additionally, the results of this study can be used to develop the Glucose Syrup Quality Prediction Model based on pH parameters and hydrolysis time.

Limitations of the Study

This study has several limitations, including:

The study only investigated the effect of pH and hydrolysis time on the quality of glucose syrup, and did not consider other variables that may affect the quality of the product.
The study only used tapioca as the raw material, and did not investigate the effect of other starch sources on the quality of glucose syrup.
The study only used acid hydrolysis as the method of starch breakdown, and did not investigate the effect of other methods on the quality of glucose syrup.

Conclusion

In conclusion, this study provides valuable insights into the effect of pH and hydrolysis time on the quality of glucose syrup produced from tapioca using acid hydrolysis. The results of this study can be used to optimize the production process and produce high-quality products. However, further research is needed to investigate the effect of other variables on the quality of glucose syrup and to develop the Glucose Syrup Quality Prediction Model based on pH parameters and hydrolysis time.
