Teknologi Pembuatan Membran Nata Kedaireka MF Th 2023
Summary
TLDRThis video introduces the innovative creation of Nata de Soya, a food product transformed into a filter membrane. Utilizing waste materials from tofu and tempeh production, the process involves boiling the ingredients with sugar and sterilizing them before pressing. The final product, a membrane filter, effectively purifies coffee, milk, and water, while also filtering bacteria. The detailed steps highlight the eco-friendly aspect of repurposing waste into a functional product, showcasing the potential for sustainable solutions in food processing.
Takeaways
- 😀 Nata de soya is a food product made with the help of Acetobacter xylinum bacteria, using liquid waste from tofu.
- 🌱 The primary purpose of making Nata de soya in this context is to create a filter membrane rather than a food item.
- 💧 The filter membrane can be used for various applications, including filtering coffee, milk, water, and even bacteria.
- 📊 Three different compositions are used to produce the Nata de soya, varying the ratios of tofu liquid waste and coconut water.
- 🍬 Each composition includes added sugar (1 kg) and a small amount of Za (100 grams) for the fermentation process.
- 🔥 The production process involves heating the mixture to a warm temperature before adding sugar, which acts as a carbon source.
- 🧼 Sterilization of materials, such as newspapers, is crucial for ensuring a hygienic production environment.
- ⏳ After boiling, the mixture is allowed to cool and is covered with sterilized newspaper for 24 hours for fermentation.
- 💧 The membrane filtering process involves both cold pressing to remove excess water and hot pressing to form sheets.
- 📹 The video aims to educate viewers about the step-by-step process of creating Nata de soya and its uses.
Q & A
What is Nata de Soya?
-Nata de Soya is a food product made with the help of bacteria, specifically Acetobacter xylinum, using soy milk as the main ingredient. It is produced from waste liquids generated in tofu production.
What alternative uses does Nata de Soya have?
-In this context, Nata de Soya is not made for consumption but is utilized as a filter membrane. It can filter beverages like coffee and milk, as well as bacteria from liquids.
What are the three compositions used in the Nata de Soya production?
-The three compositions include: 1) 40% tofu waste liquid, 40% tempeh waste liquid, and 20% coconut water; 2) 80% tofu waste liquid and 20% coconut water; 3) 80% tempeh waste liquid and 20% coconut water, with added sugar and vinegar.
How much Nata de Soya is being produced in this demonstration?
-In this demonstration, 20 liters of Nata de Soya are being produced, using 16 liters of tofu waste liquid and 4 liters of coconut water.
What role does sugar play in the Nata de Soya production process?
-Sugar serves as a carbon source during the production of Nata de Soya, promoting the growth of bacteria that facilitate the fermentation process.
What is the process of sterilizing the newspaper used in the production?
-The newspaper used in the production is sterilized by ironing it, ensuring it is free from contaminants before being used to cover the Nata de Soya mixture.
What are the two pressing methods used to create the filter membrane?
-The two pressing methods used are cold pressing and hot pressing. Cold pressing reduces the moisture content, while hot pressing forms the Nata into a solid filter membrane.
How long does the Nata de Soya need to rest after being poured into the tray?
-After pouring the mixture into the tray, it needs to rest for 24 hours before inoculation, allowing the fermentation process to occur.
What are the final products obtained from the Nata de Soya production process?
-The final product is a filter membrane made from the Nata de Soya, which can be used for filtering various liquids, including coffee, milk, and even bacteria.
What is the significance of using waste materials in this production process?
-Using waste materials like tofu and tempeh byproducts helps reduce environmental waste while creating a valuable product, promoting sustainability and resource efficiency.
