Against the backdrop of the continuous expansion of the global dried fruit market, China, as a major producing country, faces food quality control and international trade barriers caused by imperfect standard systems. This study was based on a systematic review of 11 international and domestic standards for dried fruit products, compared and analyzed the differences in key quality indicators such as sensory evaluation, moisture content, total acidity, total sugar, ash content and impurities. The study found that although China's current standards were stricter than international standards in terms of total acidity, total sugar, and impurity limits, there were prominent issues such as a chaotic grading system for sensory indicators, lack of consistency in moisture threshold values (e.g., the domestic standard moisture limit for raisins was 15 g/100 g to 20 g/100 g), and significant differences in total sugar limits (e.g., different standards for dried dates require total sugar levels ranging from 60% to 75%). Additionally, some indicators (such as the moisture limit for dried peaches at 30 g/100 g) were lower than international standards (ISO 7703:1995 limit less than or equal to 20%). This study recommends: Adopted a dual-track optimization approach of “integrating domestic standard systems+breaking through international standard strategies”, accelerated the formulation and implementation of national standards for dried fruit food safety to strengthen supervision, systematically revise industry standards to eliminate indicator conflicts, and take the lead in developing international standards for specialty products, thereby comprehensively enhancing the quality competitiveness of China's dried fruit industry and its voice in international standard setting.
