A19 Deep Sea Line-Caught Tuna Belly Blocks

Product Introduction

These premium tuna blocks are wild line-caught from deep open ocean, including Bluefin Tuna Otoro (Fatty Belly), Yellowfin Tuna Chutoro (Medium Fat Belly) and Bigeye Tuna loin cuts. All fish are immediately flash-frozen at ultra-low temperature on the fishing vessel right after harvest to lock in original tender texture, rich marbling fat and natural ocean sweetness. They are top-tier ingredients for high-end Japanese sashimi, nigiri sushi and seared tuna dishes, perfect for home Japanese food making, banquet serving and premium gift giving.

Different Cuts Features

1. Bluefin Tuna Otoro (Top Fatty Belly) The most luxurious part of bluefin tuna with abundant marble-like fat streaks. The flesh shows gradient pinkish-red color, ultra-soft and melt-in-your-mouth texture with rich buttery fatty aroma. It is regarded as the premium king of sashimi with lingering sweet aftertaste.

2. Yellowfin Tuna Chutoro Cost-effective classic belly cut with balanced fat and lean meat. Firm, bouncy texture with clean umami flavor without greasiness. Ideal for daily sashimi, nigiri and lightly torched seared dishes.

Core Selling Points

1. Wild Deep Sea Line Fishing, Pollution-Free Habitat Caught by longline fishing in remote open ocean, far away from coastal water pollution. Wild deep-sea living environment creates firmer meat and superior natural flavor compared with farmed alternatives.

2. Ultra-Low Temperature Flash Freezing Onboard After being caught, each tuna is immediately bled, gutted, processed and frozen at -60℃ ultra-low temperature on the boat. This technology prevents cell damage and keeps the texture almost identical to fresh-caught fish after thawing. No repeated freezing, no water soaking for weight gain, meat will not turn mushy or dry.

3. Professionally Trimmed Boneless Solid Blocks Each block is precisely trimmed by experienced workers to remove bones, tough fascia and bloody parts. Neat thick chunks allow you to cut thick or thin slices freely for sashimi without complicated secondary processing.

Storage & Thawing Tips

1. Store unused tuna blocks in freezer at -18℃ for long-term preservation immediately after receipt;

2. For raw sashimi eating: thaw slowly in refrigerator chiller compartment. Do NOT soak in room-temperature water for fast thawing, which will ruin the firm texture;

3. Raw eating is recommended only for people with strong digestive systems. Sensitive stomach groups should fully cook the tuna before eating.
