A major technological leap solves industry bottlenecks in large-scale standardized production

The Fisheries Machinery Research Institute of the Chinese Academy of Fishery Sciences has successfully overcome key technological bottlenecks to develop high-quality sashimi oyster products. This green purification and quality improvement technology addresses long-standing industry issues, including poor synergy in traditional sterilization methods, high energy and water consumption, and a lack of automation.

By constructing an innovative circulating water purification mode that combines ozone and ultraviolet multi-barriers with a biofilm system, the institute has optimized the sterilization process so that the oysters meet strict standards for raw consumption. This new procedure solves the common problems of uneven purification, flavor loss, and declining vitality during commercial circulation. Additionally, the team independently developed an automated turnover system capable of handling the entire process from clean cleaning and flexible crating to green purification, paving the way for large-scale, intelligent production.

The reliable product support generated by this complete set of core technologies ensures that the quality and safety indicators of the purified oysters fully meet the rigorous requirements of GB10136 "National Food Safety Standard for Animal-Derived Aquatic Products" and DBS44/006 "Microbial Limits for Non-Prepackaged Ready-to-Eat Foods in Catering Services" for raw aquatic products.

Recognizing these advancements, The Guangdong Fisheries Society organized an expert evaluation meeting in Guangzhou to review the project alongside related seafood innovations. The meeting was chaired by Chen Jianguang, Secretary-General of the Society, and featured an esteemed evaluation committee. The panel included Professor Wu Zhaohe from Zhongkai University of Agriculture and Engineering, Professor Du Hong from Shantou University, Researcher Pan Jianyu from the South China Sea Institute of Oceanology, Chinese Academy of Sciences, Professor Zhou Aimei from South China Agricultural University, and Associate Professor Cui Chun from South China University of Technology.

During the session, project leaders detailed their respective findings to the panel:

"The achievements systematically studied raw material quality maintenance and ultrasonic synergistic improvement technology, low-temperature cooking pre-processing technology, packaging materials, and packaging methods. They constructed a full-chain quality assurance technology system from raw materials to the cold chain, formed a complete solution for high-quality oyster pre-processed food processing technology, and developed high-quality oyster pre-processed food products."

Following this, the specific breakthrough regarding raw consumption was presented:

"The results systematically studied technologies such as ozone and artificial seawater green purification technology for oysters, commercial live-keeping and distribution technology, purification turnover system and purification equipment system, forming an integrated technology for green purification and quality improvement of oysters, and developing high-quality sashimi oyster products."Researcher Ni Jin, project leader of "Integrated Technology for Green Purification and Quality Improvement of Oysters"

Following a comprehensive review, the expert panel unanimously agreed that these new technologies and products are highly innovative, possess immense market potential, and have officially reached an advanced level in China.

中国の科学者が緑色の水産物浄化で画期的な進歩を達成、専門家は高度な新型サシミ生牡蠣製品を称賛

主要な技術的飛躍により、大規模な標準化生産における業界のボトルネックを解決

中国水産科学研究院漁業機械儀器研究所は、主要な技術的ボトルネックを克服し、高品質なサシミ生牡蠣製品の開発に成功した。この緑色の浄化および品質向上技術は、従来の殺菌方法における相乗効果の低さ、高いエネルギーと水の消費量、自動化の不足など、長年にわたる業界の課題に対処するものである。

オゾンと紫外線によるマルチバリアとバイオフィルムシステムを組み合わせた革新的な循環水浄化モードを構築することにより、同研究所は殺菌プロセスを最適化し、牡蠣が生食の厳格な基準を満たすようにした。この新しい手順は、商業流通時における不均一な浄化、風味の損失、および活力の低下という共通の課題を解決する。さらに、同チームは、洗浄、柔軟な箱詰めから緑色浄化に至る全プロセスを処理できる自動ターンオーバーシステムを独自に開発し、大規模でインテリジェントな生産への道を開いた。

この一連のコア技術によって生み出された信頼性の高い製品サポートは、浄化された牡蠣の品質および安全指標が、生用水産物に対するGB10136「食品安全国家基準 動物性水産物」およびDBS44/006「飲食サービスにおける非包装即食食品の微生物限界量」の厳格な要求を完全に満たすことを保証している。

これらの進歩を認め、広東省水産学会は、関連する水産物の革新技術とともに本プロジェクトを審査するため、広州で専門家評価会議を開催した。会議は同学会の秘書長である陳建光が議長を務め、著名な評価委員会が参加した。専門家パネルには、仲愷農業工程学院呉灶和教授汕頭大学杜虹教授中国科学院南海海洋研究所潘建宇研究員華南農業大学周愛梅教授、および華南理工大学崔春副教授が含まれている。

セッション中、プロジェクトのリーダーたちはそれぞれの成果の詳細をパネルに説明した:

「この成果は、原料の品質維持および超音波相乗向上技術、低温調理前処理技術、包装材料、および包装方法について系統的に研究したものである。原料からコールドチェーンにいたる全チェーンの品質保証技術体系を構築し、高品質な牡蠣調理済み食品加工技術の完全なソリューションを形成し、高品質な牡蠣調理済み食品を開発した。」 — 広東海洋大学の「牡蠣調理済み食品の統合技術および新製品」プロジェクトリーダー、鄭恵娜教授

これに続き、生食に関する具体的な画期的進歩が発表された:

「この成果は、牡蠣のオゾンおよび人工海水による緑色浄化技術、商業的な活魚保持および流通技術、浄化ターンオーバーシステムおよび浄化設備システムなどの技術を系統的に研究し、牡蠣の緑色浄化および品質向上の統合技術を形成し、高品質なサシミ生牡蠣製品を開発したものである。」 — 「牡蠣の緑色浄化および品質向上統合技術」プロジェクトリーダー、倪錦研究員

総合的な評価を経て、専門家パネルは、これらの新技術および新製品が非常に革新的であり、莫大な市場の潜在力を有し、中国において公式に先進的なレベルに達していることに満場一致で同意した。
