Abstract

     Hue pomelo (Citrus grandis (L.) Osbeck) is a specialty fruit tree of Thua Thien Hue province. To establish a scientific basis for registering “Hue” geographical indications for pomelo products, this article focuses on researching the reputation, sensory quality, and biochemical quality of Hue pomelo products through the analysis of morphological characteristics, biochemical quality, and processing using statistical methods. The research results show that: (1) Hue pomelo  as a long-standing reputation recognized by both businesspeople and consumers; (2) In terms of sensory quality and biochemical quality, Hue pomelo products exhibit distinctive characteristics compared to those of the same type from other regions; for instance, small size (average weight ranging from about 0.7-1 kg per fruit), pear-shape with a flat stem end, the ripe peel is greenish-yellow and smooth with a natural light fragrance, slender segments are small, straight, firm, crunchy with a slightly sweet and mildly sour taste that is not bitter or astringent. The oluble solids content (Brix degree, %) ranges from 9.42-11.23; total sugar content ranges from 7.80-9.34%; total acid content ranges from 0.58-0.71%, and Vitamin C content ranges from 59.29-66.20 mg/100 g.
