3项虾青素团体标准！南工大合成生物工程团队牵头制定

Core Viewpoint - The recent release of three group standards for astaxanthin production by Nanjing University of Technology marks a significant step in standardizing production technology in China, providing essential technical support for high-quality industry development [2][6]. Group 1: Standards Overview - The three standards include: 1. "Technical Requirements for the Production of Natural Astaxanthin for Health Foods," which outlines raw material selection, production processes, quality control, and safety evaluations to ensure compliance with food safety and efficacy requirements [12]. 2. "Quality Grade Evaluation of Natural Astaxanthin Raw Materials for Health Foods," which establishes quality grading standards for natural astaxanthin in health food applications, promoting high-quality industry development [12]. 3. "Technical Requirements for the Microbial (Red Yeast) Fermentation Method for Synthesizing Natural Astaxanthin," which provides systematic regulations covering strain selection, fermentation processes, extraction, purification, and product testing to promote green and efficient production technologies [12]. Group 2: Market Potential and Applications - Astaxanthin, a potent antioxidant, is widely used in health foods, cosmetics, and aquaculture, with increasing demand for natural products expected to drive market growth. The market size for astaxanthin is projected to reach $3.4 billion by 2027 [7]. - The successful heterologous synthesis of (S)-astaxanthin by the research team has achieved a yield of 0.9 g/L, and through adaptive evolution, a yeast strain has been developed that produces 4.6 times more astaxanthin at 25°C compared to the original strain [9]. - Various products have been developed for market release, including fish feed, carotenoid essential oils, pet snacks, and probiotics, facilitating the industrial application of this technology across multiple sectors [9].
