1, Hefei market I'm not sure. I'm here in Shenzhen. Generally speaking, the bulk bird's nest in shopping malls and pharmacies is about 40-90 yuan/gram. The price is quite high and the quality is uneven. I saw the other day that the small swallow strips with Tongrentang brand were all made in 39 yuan/gram, and they were made in Hainan. As we all know, Indonesia is the largest producer of bird's nest, followed by Malaysia; The best quality cave swallow in Thailand (this kind is about 200 yuan/gram, and it is extremely difficult to see in the market); Followed by Indonesia and Malaysia. 2. "Packaged" Do you mean gift boxes? This is related to the quantity of packaging. You can calculate the approximate price with the unit price. 3. Bird's nest is graded. The main identification conditions are shape, size, origin, quality, etc. Because Jin Siyan builds nests three times a year, the first time it is built with high purity, large size and the best quality; The last time was worse. Of course, most of the very beautiful, white and seamless bird's nests on the market are bleached and glued, especially in the mainland market. Because a large part of the cost of bird's nest is the cost of manual selection, picking hairs by hand is a delicate job. A skilled worker can only pick about ten Bai Yan (official swallows) a day, and it is even more difficult for blood swallows to pick hairs, only about five a day. Therefore, many unscrupulous businessmen will take advantage of the fact that most mainland customers are not in contact with bird's nest, and use bleaching to soak the bird's nest in hydrogen peroxide, so that there is almost no swallow hair, and the bird's nest is white and beautiful! Moreover, pure hand-picked hair often has a gap in the swallow cup after picking hair, and some merchants use glue to make it look good and heavy. However, only the shell of the bleached and glued bird's nest is beautiful. What do you think of the real nutrition? In addition, the bird's nest in the shopping mall is not necessarily fake, so you must keep your eyes open. After all, what you eat in your stomach is not a child's play.
