严苛的类GAP采收质量管理规范

优质基因库保护

三江源的每一支冬虫夏草均精选自冬虫夏草的最优质产区——青海玉树。青海省虫草资源非常丰富,数量和质量均居全国之冠。其中处于三江源核心区的玉树州冬虫夏草产量占青海省总产量的60%以上。青海三江源药业集团运用规范化管理和质量监控手段,保护三江源冬虫夏草种质资源和优质基因库,实现三江源神草原材的标准化、现代化。

最佳采收时间

每年5月1日至6月20日左右,三江源野生冬虫夏草的产地都有一次10至20天左右的采挖期,专家团队依据当时和往年同期天气冷暖对比情况,将准确预测出最精确当年头草的采挖时间。一般在晴天的清晨8点至11点进行,此时段采挖,首先因为光照角度适宜,易于在草丛中发现露出地表的冬虫夏草子座;其次该时段的冬虫夏草虫体含水量适宜,子座长度适宜,多为最为珍贵的头草,菌香味浓郁,药用价值最高。

Harvest

Strict harvest quality management regulation GAP

Protection on high quality gene bank

Qinghai Sanjiangyuan Pharmaceutical Group applies standardized management and quality control measures to protect wild resources and ecological environment so as to realize sustainable utilization of precious aweto resource to protect high quality Sanjiangyuan aweto species and gene bank as well as to realize standardization and modernization of Sanjiangyuan aweto.

Best time for harvesting

There is a harvesting period of 12 to 26 days from May 1st to June 20th every year in the production area of aweto in Sanjiangyuan. The team of expert will precisely predict the best time for the first harvest with weather condition compared with that of previous years.

Reserved under vacuum and freezing condition

The cordycepic acid, adenosine, amino acid and microelement as well as activity and available nutrients of the aweto can be reserved by application of international advanced cryogenic vacuum freeze drying technology. Through this technology, the retention rate of effective constituent of aweto can reach 98% or above.

Harvest quality standards

Complete shape with upper part to be the stroma and the lower part to be the dead larva; the larva is golden yellow while the eye part is brownish red; the length of the dead larva is above 4 cm and diameter is above 0.5cm without any damage or mildew spot on the surface; 20~30 rings on the back and 8 pairs of feet in the abdomen part, among which 4 pairs are visible in the middle part; the section part of the body is white and full and the centerline is the residue of digestive tract; you can see 6-30μ bristle on the epidermis via observation by microscope and the wall of the body is thick with obvious intrusion by hypha. There are residues of angular visceral in the middle part; one stroma, seldom 2~3.It grows from the head part of the host with length > 7 cm. This length is the most prominent feature for a high quality aweto for the first harvest; the diameter of the stroma root is > 2.5mm and becomes thinner towards the upper part; the head part is brown and almost in the shape of round column. It is full at the beginning but hollow in the later period; you can see that the perithecium grows near the surface while the root is slightly embedded into the stroma in shape of oval or egg via observation by microscope, 380-550μ* 140-240μ; two asco-spores with several diaphragms, 160-470μ * 5-6.5μ.
