Organization, Consolidation and Presentation Of Financial Statements [Abstract]
Organization and Principal Activities	1. ORGANIZATION AND PRINCIPAL ACTIVITIES In these condensed consolidated financial statements, unless the context requires otherwise, the terms “we”, “our”, “us” and the “Company” refer to Tanke Biosciences Corporation, a Nevada corporation formerly known as Greyhound Commissary, Inc. (“Greyhound”), as well as our direct and indirect subsidiaries, and our principal operating business, Guangzhou Tanke Industry Co., Ltd. (“Guangzhou Tanke”), a company organized under the laws of the People’s Republic of China (“China” or the “PRC”), which we control via a series of variable interest entity contractual agreements (the “VIE Agreements”) more fully described below. We conduct our business through our subsidiaries, principally our wholly-owned subsidiary China Flying Development Limited (“China Flying”), a Hong Kong incorporated company, and its wholly-owned subsidiary Guangzhou Kanghui Agricultural Technology Co., Ltd. (“Kanghui Agricultural” or the “WFOE”), a wholly foreign owned enterprise incorporated as a limited liability company under the laws of the PRC. The Company operates and controls Guangzhou Tanke through Kanghui Agricultural and China Flying and in connection with the VIE Agreements. On January 3, 2011, Guangzhou Tanke entered into a series of agreements with Kanghui Agricultural, pursuant to which Kanghui Agricultural effectively assumed management of the business activities of Guangzhou Tanke. Kanghui Agricultural is entitled to 100% of the net income of Guangzhou Tanke and is able to direct Guangzhou Tanke’s actions. Also on January 3, 2011, our board of directors unanimously approved a resolution to enter into a Share Exchange Agreement with China Flying, and Golden Genesis Limited, a British Virgin Islands company ("Golden Genesis"), the sole stockholder of China Flying. Under the terms of the Share Exchange, Golden Genesis exchanged 100% of its capital stock in China Flying for 10,758,000 shares of authorized, but previously unissued Greyhound common stock, post-split as described below. Also, at the closing, we issued an aggregate of 2,166,903 shares (post split) of our authorized, but previously unissued common stock to a U.S. advisor. Following the closing of the agreement on February 9, 2011, China Flying became our wholly owned subsidiary. Our board of directors further approved unanimously on January 3, 2011, a one share for 8.512 shares reverse split of our issued and outstanding common stock. The effective date of the split was established by our board on a date prior to the closing of the acquisition of China Flying. The acquisition of China Flying was contingent upon the completion of our planned private placement in which we sold 6,669,627 units (the “Units”), with net proceeds of $6,522,563. Each Unit consisted of a $1.15 principal amount convertible note and a three year warrant to purchase one share of Greyhound common stock. On February 9, 2011, the Company entered into a Securities Purchase Agreement with individual investors relating to the private placement and completed the private placement transaction (see Note 9 below). The proceeds from such sale will be used to finance the operations and growth of Guangzhou Tanke. At the time of the Share Exchange Agreement, Greyhound had 3,397,787 shares of common stock issued and outstanding. Following the reverse split, but prior to the issuance of shares pursuant to the acquisition of China Flying, the outstanding shares were reduced to 399,180 shares. Split shares issued in connection with the reverse stock split were fully paid and non-assessable. The number of stockholders will remain unchanged as a result of the reverse split. The par value of our common stock remained unchanged. As management of Guangzhou Tanke obtained control of the Company, the Share Exchange was treated as a reverse merger. Accordingly, for accounting purposes Guangzhou Tanke was the acquirer so historical financial information presented herewith is that of Guangzhou Tanke. Consequently, there was no step-up in the basis of the assets of Guangzhou Tanke, as Guangzhou Tanke was the acquirer for accounting purposes. Pursuant to the VIE Agreements, Kanghui Agricultural has the right to advise, consult, manage and operate Guangzhou Tanke for a quarterly fee equal to Guangzhou Tanke’s net income. Additionally, the Tanke Shareholders pledged their rights, titles and equity interest in Guangzhou Tanke as security for Kanghui Agricultural to collect consulting and services fees provided to Guangzhou Tanke through an Equity Pledge Agreement. In order to further reinforce Kanghui Agricultural’s rights to control and operate Guangzhou Tanke, the Tanke Shareholders granted Kanghui Agricultural an exclusive right and option to acquire all of their equity interests in Guangzhou Tanke through an Option Agreement. Neither Tanke Biosciences nor Kangui Agricultural own the assets or are responsible for the liabilities of Guangzhou Tanke. The VIE Agreements were necessary because without them, the shareholders of Tanke Biosciences would not have control of Guangzhou Tanke. With these in place, however, Guangzhou Tanke is contractually equivalent to a subsidiary of Tanke Biosciences. Guangzhou Tanke has historically self financed, and has been a profitable enterprise. However, on February 9, 2011, Tanke Biosciences sold convertible notes payable (see Note 9 below) with net proceeds of $6,522,563. Such proceeds will be used to finance the operations and growth of Guangzhou Tanke. As Tanke Biosciences has complete control over Guangzhou Tanke, all assets presented on the balance sheet of Tanke Biosciences are available to settle obligations of Tanke Biosciences. Furthermore, there are no liabilities on the balance sheets of Guangzhou Tanke that do not have recourse against the assets of Tanke Biosciences. As Guangzhou Tanke is our sole operating entity, nearly all operating assets and liabilities are those of Guangzhou Tanke. “RMB” and “Renminbi” refer to the legal currency of China and “$”, “US dollar” and “US$” refer to the legal currency of the United States. Overview of Our Business Through Guangzhou Tanke, our principal operating business, we are one of the leading animal nutrition and innovative feed additive providers in China. Our products are distinguished from traditional artificial feed additives in that they are environmentally-friendly and are designed to optimize the growth and health of livestock such as pigs and cattle, as well as farmed fish.
