Chemical and Functional Characteristics of Composite Flour from Modified Kasava Flour and Flour

Introduction

The production of composite flour from modified kasava flour and flour has gained significant attention in recent years due to its potential to improve the nutritional content and functional characteristics of traditional flour-based products. Kasava flour, a staple ingredient in many African countries, is rich in nutrients and has been shown to have various health benefits. However, its use in food products is limited due to its high starch content and low gluten content. In this study, we aim to investigate the chemical and functional characteristics of composite flour produced from modified kasava flour and flour using various drying methods and flour ratios.

Research Methodology

This study employed a complete randomized design (CRD) to investigate the effects of two main factors on the chemical and functional characteristics of composite flour. The first factor was the type of kasava flour modified with four different drying methods, namely:

M1: Drying using sunlight: This method involves drying the kasava flour under direct sunlight, which is a traditional method used in many African countries.
M2: Drying with solar dryers: This method involves using solar dryers to dry the kasava flour, which is a more modern and efficient method.
M3: Drying using a stove: This method involves drying the kasava flour using a stove, which is a common method used in many households.
M4: A combination of solar dryers and stoves: This method involves combining the use of solar dryers and stoves to dry the kasava flour.

The second factor involved a mixture ratio between wheat flour and kasava flour modified with different ratios, namely:

T1: 90% wheat flour and 10% kasava flour: This ratio is commonly used in traditional flour-based products.
T2: 80% flour and 20% kasava flour: This ratio is used to improve the nutritional content of traditional flour-based products.
T3: 70% flour and 30% kasava flour: This ratio is used to create a more balanced blend of wheat flour and kasava flour.
T4: 60% flour and 40% kasava flour: This ratio is used to create a more nutritious and functional composite flour.

Tested Parameters

Some of the parameters analyzed in this study include:

Water content (%): This parameter measures the amount of water present in the composite flour.
Ash content (%): This parameter measures the amount of inorganic compounds present in the composite flour.
Fat content (%): This parameter measures the amount of fat present in the composite flour.
Protein content (%): This parameter measures the amount of protein present in the composite flour.
Food fiber content (%): This parameter measures the amount of dietary fiber present in the composite flour.
Absorption of water and oil (g/g): This parameter measures the ability of the composite flour to absorb water and oil.
Swelling power (g/g): This parameter measures the ability of the composite flour to swell when exposed to water.
Expansion when baking (baking expansion) (ml/g): This parameter measures the ability of the composite flour to expand when baked.

Research Results

The results of this study indicate that the type of modified kasava flour and the drying method used has a very significant effect on protein content, expansion when baked, and significant effect on flour flower power. In addition, the ratio of a mixture of flour and kasava flour also shows a very significant effect on various parameters, including water content, fat, protein, food fiber, water and oil absorption, flower power, and expansion when baked.

Additional Analysis and Explanation

From the results of this study, it appears that the selection of the right type of kasava flour and the appropriate drying method is very important in improving the quality of composite flour. For example, the use of drying with sunlight (M1) can maintain better nutritional content compared to drying using a stove (M3), which tends to reduce nutritional content due to excessive heating.

The ratio of flour and kasava flour also plays an important role in determining the final quality of composite flour. Wheat flour which has a high gluten content gives structural strength to the dough, while Kasava flour adds additional nutrients and can increase functional characteristics, such as water and oil absorption.

Conclusion

This study provides significant added value to the food industry and flour-based processed products. By understanding the chemical and functional characteristics of this composite flour, producers can create more quality products and in accordance with consumer tastes and nutritional needs. Further development of this study can also open new opportunities in healthier and nutritious flour-based product innovations.

Recommendations

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

The use of drying with sunlight (M1) is recommended for maintaining better nutritional content.
The use of a combination of solar dryers and stoves (M4) is recommended for improving the quality of composite flour.
The ratio of 70% flour and 30% kasava flour (T3) is recommended for creating a more balanced blend of wheat flour and kasava flour.
Further research is needed to investigate the effects of other drying methods and flour ratios on the chemical and functional characteristics of composite flour.

Limitations

This study has several limitations, including:

The use of a small sample size.
The lack of control over environmental factors.
The limited number of parameters analyzed.

Future Directions

This study provides a foundation for further research in the area of composite flour production. Future studies can investigate the effects of other drying methods and flour ratios on the chemical and functional characteristics of composite flour. Additionally, further research can be conducted to investigate the potential health benefits of composite flour and its potential applications in various food products.
