Introduction

The Medan Industrial Research and Standardization Center has conducted an analysis of several important parameters of wheat flour, namely water content, ash content, protein content, and falling number. This analysis process uses several methods that have been proven effective in determining the quality and nutritional value of flour. The water content is determined by the gravimetric method, the gray content by the dry ashing method, the protein content by the semi-micro-kjeldahl method, and the falling number is measured using a special instrument.

Analysis Method

Each method used has its own advantages and ways of working. Understanding these methods is crucial in determining the accuracy and reliability of the results.

1. Water Content

The gravimetric method is the most common technique used to determine the water content in food ingredients. This process involves drying the sample at a certain temperature until the weight is stable, so that the water content can be calculated. The gravimetric method is widely used in the food industry due to its simplicity and accuracy.

2. Ash Content

Dry ashing method is the process of burning samples at high temperatures to eliminate organic material, leaving ash as a residue. From this remaining, ash content can be calculated and provide information about the minerals contained in flour. The dry ashing method is a reliable technique for determining the ash content of flour, which is essential in understanding the nutritional value of the flour.

3. Protein Levels

The semi-micro-kjeldahl method calculates the levels of nitrogen contained in protein, which is then converted into protein content. This technique is effective in estimating the quality and nutritional value of flour. The semi-micro-kjeldahl method is widely used in the food industry due to its accuracy and reliability.

4. Falling Number

Falling number measurements are carried out to assess the quality of flour in terms of enzyme activity, especially amylase. The higher the falling number value, the better the flour quality, which means that flour has a low enzyme activity. The falling number is an essential parameter in determining the suitability of flour for various culinary applications.

Results and Quality Standards

The results of the analysis showed that water content, ash content, protein content, and falling number from the wheat flour under study were within the limits in accordance with the quality standards of SNI 3751: 2009. This shows that the flour has good quality and is suitable for use in the food industry.

The Importance of Water Content Analysis, Ash Content, Protein Content, and Falling Number

Analysis of water content, ash, protein, and falling number is very important in determining the quality of flour. Flour with the right water content will have a better shelf life, while the gray content can provide an indication of the minerals in the flour. Protein content directly affects the structure and texture of the final product, such as bread and pasta. Meanwhile, falling number can show potential problems in the manufacturing process, especially if the flour will be used in the bread industry.

Conclusion

Through an analysis conducted at the Medan Industrial Research and Standardization Center, it can be concluded that the wheat flour studied meets the established quality standards. This is important to maintain the consistency and safety of food products produced. With a better understanding of the characteristics of flour, producers can optimize the use of this material in various culinary applications.
