The round plump beans actually remind one of the vast and fertile black soil in Heilongjiang. It is said that bean curd. the earliest known bean product, can be dated to as far back as the time of Christ! I enjoyed the full taste and flavor of Heilongjiang bean curd. and was able to thrive on the dish.展开更多

This research investigated the presence and levels of Zn in muscle and brain tissues of C. gariepinus sourced from selected markets in Delta State. Replicate adult fish samples were obtained from seven market locations in Oleh, Asaba, Ekpan, Ogwashi-Ukwu, Okere, Abraka and Ughelli towns, labeled and taken to the laboratory in iced coolers. The presence and levels of the heavy metal were determined spectrophotometrically. Concentrations ranged from 0.015 - 0.19 (0.09 ± 0.02) mg/kg d.w. in muscle and 0.035 - 0.36 (0.16 ± 0.03) mg/kg d.w. in brain tissues, even as accumulation levels differed significantly (t = 0.005) between the tissues at p < 0.05. There was also significant locational heterogeneity in accumulations of the metal [F<sub>(100.97)</sub> > F<sub>crit(4.02)</sub>] at the 95% confidence limit;with least accumulation of 0.03 (±0.01) mg/kg d.w. recorded in fish samples obtained from Ughelli and maximum accumulation of 0.28 (±0.07) mg/kg d.w. recorded in those obtained from Oleh locations. However, levels were below the Food and Agricultural Organization and World Health Organization acceptable limits for Zn in edible fish. Results revealed that lipophilic brain tissues accumulated more heavy metal than muscle tissues. Since accumulation levels were low, they do not currently constitute public health risks to consumers in Delta State.展开更多

The cuisine inherits from the culinary style of the people who migrated from the Central Plains to South China, and also combines the cooking skills from the imperial court that had been spread to Guangxi in the late Northern Song Dynasty (960- 1127), as well as the culinary skills from feudal officials’ private chefs in the Ming (1368- 1644) and Qing (1644-1911) dynasties.展开更多
