Nutrition of Komtan Soup

Have you ever wondered why a warm soup tastes so deeply comforting after savoring a premium 烧肉 dinner?

Hello, everyone. This is Sondo of 黑5.

After enjoying our juicy Fresh 横膈膜 and thick-cut 和牛 牛舌 root grilled to perfection over 纪州备长炭 炭火, what do you choose as the grand finale of your dinner? While finishing with a cold bowl of Reimen noodles is refreshing, taking a warm, rich soup as your final sip brings a deep sense of satisfaction and comfort that spreads throughout your entire body.

Among all our soup offerings, the one we prepare with the utmost passion is our “Komtan Soup” (also known as 牛骨高汤). The reason your body naturally craves this warm soup after eating rich meats, and why it soothes your stomach so effectively, is backed by scientific principles rather than simple emotion.

Indeed, 黑5’s Komtan Soup is often praised as a “drinkable skincare elixir” or a “natural multi-supplement” by health and beauty-conscious guests. Today, based on strict analysis data from the Food Environment Hygiene Research Institute, I would like to share the scientific nutritional properties and health benefits of our signature soup.

Our Meticulous High-Pressure Stockpot Brewing Method

Every single drop of the nutrition in our Komtan Soup comes from our uncompromising preparation process. Unlike many casual restaurants that dilute pre-made concentrates, 黑5 brews its stock entirely from scratch daily.

We source selected domestic beef bones (Genkotsu) and domestic chicken feet (Momiji), which are packed with premium gelatin. We place them tightly into our special high-pressure stockpots, brewing them under intense pressure for hours until the marrow and bone structures completely break down. This pressure-cooking method extracts glycine, proline, and other vital amino acids locked deep inside the marrow that would never dissolve under normal cooking temperatures.

Particularly, chicken feet serve as an excellent source of collagen, adding a natural, velvety texture and mild sweetness to complement the powerful, rich flavor of the beef bones. This high-pressure extraction turns the soup into a creamy, milky-white elixir that is rich in umami and nutrients. This stock is the secret behind 黑5’s dense, nourishing 牛骨高汤.

Only 0.3g of Sugars: Basic Nutrients Backed by Scientific Analysis

What exactly does this soup contain? According to official test results from the Food Environment Hygiene Research Institute, every 100g of our broth features the following nutritional values:

• Energy: 110 kcal
• Protein: 5.5 g
• Fat: 9.5 g
• Carbohydrates: 0.7 g (including 0.3g of Sugars and 0.4g of Dietary Fiber)
• Moisture: 84.1 g
• Ash: 0.2 g
• Salt Equivalent: 0.107 g (Sodium: 42 mg)
• Calcium: 0.7 mg

The most remarkable figure in this analysis is the extremely low sugar content of just 0.3g per 100g. This proves that the soup’s rich texture and flavor come entirely from natural amino acids, with zero artificial sugars or chemical additives. For guests practicing low-carb or ketogenic diets, this soup serves as an outstanding source of pure, clean energy.

Additionally, it provides a high protein content of 5.5g per 100g. Being high-protein and low-carb with a moderate energy value of 110kcal, it acts as a perfect recovery drink for tired muscles after exercise or a busy day.

The sodium level is also remarkably low, with a salt equivalent of just 0.107g. This is a fraction of the salt found in standard miso soups or broths, allowing health-conscious guests to drink every last drop completely guilt-free.

The “Drinkable Skincare Elixir” – 18 Essential Amino Acids

The main reason 黑5’s Komtan Soup is called a “drinkable skincare elixir” is its rich concentration of essential amino acids that form the building blocks of collagen in our skin, joints, and blood vessels.

Our analysis detected 18 distinct amino acids per 100g of broth:

• Glycine: 1,200 mg
• Proline: 640 mg
• Glutamic Acid: 550 mg
• Alanine: 530 mg
• Arginine: 400 mg
• Aspartic Acid: 320 mg
• Lysine: 200 mg
• Leucine: 180 mg
• Serine: 150 mg
• Valine: 130 mg
• Phenylalanine: 120 mg
• Threonine: 110 mg
• Isoleucine: 92 mg
• Tyrosine: 49 mg
• Histidine: 44 mg
• Methionine: 37 mg
• Cystine: 8 mg
• Tryptophan: Less than 25 mg

The figures for Glycine (1,200mg) and Proline (640mg) are extraordinarily high. These two amino acids are critical for synthesizing collagen to maintain skin elasticity and moisture. Drinking a single cup of our Komtan Soup supplies these vital skincare nutrients in their most bioavailable liquid form.

Furthermore, glycine is scientifically recognized for improving sleep quality and regulating the nervous system. Glutamic acid (550mg) serves as the primary energy source for renewing gut lining cells. It protects and heals your stomach wall after a heavy meal. Additionally, Alanine (530mg) supports liver health, while Arginine (400mg) promotes blood circulation and Aspartic Acid (320mg) aids in clearing fatigue. It is a true powerhouse of recovery nutrients.

Harmonizing Palate and Gut Health After 炭火-Grilled 和牛

Enjoying Komtan Soup as a 烧肉 finale creates a highly logical dietary harmony.

At 黑5, our trained staff provides tableside grilling, cooking your raw Fresh 横膈膜 and 和牛 cuts to perfection over 纪州备长炭 炭火. While this process renders out excess fat, eating a hearty meat dinner still puts your digestive system to work.

Finishing your meal with this warm 牛骨高汤 supplies glutamic acid and glycine to stimulate digestive enzymes, promoting smooth digestion. The warm liquid improves blood flow to the digestive tract, preventing bloating and morning-after stomach heaviness. Drinking our sodium-restricted, rich soup leaves you feeling completely satisfied and refreshed the next morning. This balance is what makes 黑5’s dining experience truly complete.
