The Effect of Initial Treatment in Making Purple Sweet Potato Flour on Cakes Quality

Introduction

The production of purple sweet potato flour has become increasingly popular in recent years due to its high nutritional value and potential health benefits. However, the quality of the flour can be affected by various factors, including the initial treatment process. This study aims to examine the effect of different initial treatment methods on the quality of cakes produced from purple sweet potato flour. The research method used is a random design of non-factorial groups with one factor, namely various initial treatment methods, which include blanching, soaking in sodium metabisulfit 2000 ppm, soaking in sodium metabisulfit followed by blanching, and control treatment.

The Importance of Initial Treatment in Purple Sweet Potato Flour Production

The initial treatment process is a critical step in the production of purple sweet potato flour. It can affect the quality of the flour, which in turn can impact the final product, such as cakes. The initial treatment can influence the color, texture, and nutritional content of the flour. For instance, blanching can help to remove excess moisture from the sweet potatoes, resulting in a drier and more stable flour. On the other hand, soaking in sodium metabisulfit can help to preserve the anthocyanin content of the sweet potatoes, which is responsible for the purple color and potential health benefits.

The Effect of Initial Treatment on Purple Sweet Potato Flour Quality

The results of this study showed that the initial treatment had a significant effect on some important parameters, including the color values of L, A, B, Browning Index, water content, and organoleptic colors of purple sweet potato flour. The initial treatment also had a significant impact on skin tone (crust) and content (crumb) cake, as well as anthocyanin levels contained in it. However, the initial treatment did not have a significant effect on the density of the Kamba and the organoleptic value of the flour aroma.

The Impact of Initial Treatment on Cake Quality

The initial treatment also had a significant impact on the quality of cakes produced from purple sweet potato flour. The study found that the cake produced from purple sweet potato flour with blanching treatment has proven to be the best. The cake has a fairly high anthocyanin content, which is 495.62 mg/L, good antioxidant activity with an IC50 value of 274.08 μg/ml, as well as relatively balanced water content at 22.9%. The organoleptic value received by the panelists shows that the quality of the cake can be considered satisfactory.

The Significance of This Study

This research provides a clear picture of the importance of initial treatment in the processing of purple sweet potatoes into flour. This can be a guide for the food industry to improve the quality of purple sweet potato-based products, especially in making cakes. By understanding the effect of different initial treatment, producers can choose the most effective method to achieve optimal cake quality, while utilizing the nutritional content and health benefits of anthocyanin in purple sweet potatoes.

Conclusion

In conclusion, this study highlights the importance of initial treatment in the production of purple sweet potato flour. The results of this study show that the initial treatment can significantly affect the quality of the flour and the final product, such as cakes. The study also found that blanching treatment is the most effective method in producing high-quality cakes with good antioxidant activity and balanced water content. This research can serve as a guide for the food industry to improve the quality of purple sweet potato-based products and to utilize the nutritional content and health benefits of anthocyanin in purple sweet potatoes.

Recommendations

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

The food industry should consider using blanching treatment as the initial treatment method in producing purple sweet potato flour.
Producers should choose the most effective initial treatment method to achieve optimal cake quality, while utilizing the nutritional content and health benefits of anthocyanin in purple sweet potatoes.
Further research should be conducted to explore the effect of different initial treatment methods on the quality of other purple sweet potato-based products.

Limitations of This Study

This study has some limitations that should be noted. The study only examined the effect of different initial treatment methods on the quality of cakes produced from purple sweet potato flour. Further research should be conducted to explore the effect of initial treatment on other purple sweet potato-based products. Additionally, the study only used a random design of non-factorial groups with one factor, which may limit the generalizability of the results.

Future Research Directions

Future research should focus on exploring the effect of different initial treatment methods on the quality of other purple sweet potato-based products. Additionally, researchers should investigate the effect of other factors, such as storage conditions and processing methods, on the quality of purple sweet potato flour and the final product.
