Increasing the Taste and Texture of Yogurt from Goat Milk with the Addition of Passion Fruit and Dutch Eggplant Juice

Introduction

The process of processing goat milk into yogurt is a crucial step that affects the taste and texture of the final product. In this study, the main focus is to explore the combination of yogurt flavors produced from goat milk with various starter compositions, as well as the addition of passion fruit and Dutch eggplant, which is a typical fruit of North Sumatra. The study took place at the Agricultural Product Technology Laboratory, Faculty of Agriculture, University of North Sumatra, from January to March 2010.

The Importance of Starter Composition in Yogurt Production

Starter composition plays a vital role in the fermentation of yogurt. The starter used can affect the pH and viscosity of yogurt, which in turn affects the texture and taste. In this study, variations of starter levels from 2% to 8% provide varying options, where higher levels can produce thicker and creamy yogurt. This discovery is very important for yogurt producers, as it can increase consumer attractiveness of goat milk-based products.

The Role of Passion Fruit and Dutch Eggplant in Enhancing Yogurt Taste and Texture

Passion fruit and Dutch eggplant are two fruits that are rich in nutrients and have unique characteristics that can enhance the taste and texture of yogurt. Passion fruit is known for its sour taste, while the Dutch eggplant has a softer and sweeter taste. The combination of the two fruits creates a balanced taste profile that is both refreshing and appealing. The addition of passion fruit and Dutch eggplant juice not only gives a fresh taste but also brings an attractive aroma and natural color to the yogurt.

The Benefits of Using Local Materials in Yogurt Production

Another advantage of this study is to focus on the use of local materials. Sari fruit passion fruit and Dutch eggplant are abundant fruits in North Sumatra, so that their use does not only support environmental sustainability but also the local economy. By promoting yogurt that is enriched with local fruit juice, it is expected to increase public awareness of the importance of consumption of local-based food products that are rich in nutrients.

The Potential of Goat Milk-Based Yogurt in the Market

This study provides valuable insight into the potential processing of yogurt from goat's milk with the addition of passion fruit juice and Dutch eggplant. This innovation not only enriches variations of products in the market but also provides more health benefits, considering that they are rich in vitamins and antioxidants. Through the right steps in processing, the results obtained can meet the tastes of consumers that are increasingly developing a preference for more natural and nutritious food products.

Methodology

This study used a complete factorial random design, involving two factors consisting of four levels for starter (2%, 4%, 6%, and 8%) and three levels of additional taste of fruit juice (without fruit juice, Dutch eggplant juice, and passion fruit juice). The method used for organoleptic tests in this study is non-parametric, and observed parameters include total acids, protein content, pH yogurt, texture, and organoleptic aspects which include color, aroma, and taste.

Results and Discussion

The results showed that the variation of starter levels and the addition of passion fruit juice and the Dutch eggplant contributed significantly to the achievement of the taste and quality of yogurt which was excellent. The study found that the combination of passion fruit and Dutch eggplant juice not only gave a fresh taste but also brought an attractive aroma and natural color to the yogurt. The use of local materials in yogurt production not only supports environmental sustainability but also the local economy.

Conclusion

In conclusion, this study provides valuable insight into the potential processing of yogurt from goat's milk with the addition of passion fruit juice and Dutch eggplant. This innovation not only enriches variations of products in the market but also provides more health benefits, considering that they are rich in vitamins and antioxidants. Through the right steps in processing, the results obtained can meet the tastes of consumers that are increasingly developing a preference for more natural and nutritious food products.

Recommendations

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

Yogurt producers should consider using local materials such as passion fruit and Dutch eggplant in their products to enhance the taste and texture of yogurt.
The use of starter composition with varying levels of 2% to 8% can produce thicker and creamy yogurt, which can increase consumer attractiveness of goat milk-based products.
The promotion of yogurt that is enriched with local fruit juice can increase public awareness of the importance of consumption of local-based food products that are rich in nutrients.

Future Research Directions

Future research directions include:

Investigating the effects of different types of fruit juice on the taste and texture of yogurt.
