Mulberry tea is the product that has been paid attention to by both domestic and international consumers, accounting from the increasing growth rate of domestic market as well as the rising trend of export volume and value. Current mulberry tea production is in the form of industrial manufacturing or cooperatives that scatter in all regions of Thailand. In 2008 The Queen Sirikit Institute of Sericulture has coordinated with the The National Bureau of Agricultural Commodity and Food Standards (ACFS) to establish the Thai Agricultural Standard to create consumer’s trust in quality and safety of the product and to improve Thai agricultural commodity to be more acceptable. The provisions of this standard are based on the information of the following documents: Notification of Ministry of Public Health No. 28 (B.E. 2547) on Herbal Tea; TCPS 30/2546, Thai Community Product Standard on Mulberry Tea; CODEX STAN 1-1985.

B.1.2 Sampling procedure means an establishment of sample collecting method and specifying sample size of a lot for examination in order to obtain information for deciding whether to accept or reject a lot. It is divided into two levels as follows: (1) Primary sampling procedure means a direct sample collection from a lot to represent the product lot in sufficient quantity for the analysis and to make a decision to accept the lot. (2) Secondary sampling procedure means combining primary sample homogenously and decreasing the sample size to an appropriate number before analysis and making decision to accept the lot. B.2 Method of Primary Sampling B.2.1 Randomly sample a lot of mulberry tea according to the sample size indicated in Table B.1 (for package with weight not exceeding 1 kg), Table B.2 (for package with weight exceeding 10 kg). For package that weighs more than 1 kg but less than 10 kg can refer to either Table B.1 or B.2. The primary sampling shall examine the package, label, net weight, health claim and official inspection mark or certification mark. B.2.2 If the results of the sample meet with the provisions of Section 9 and 10 it shall be considered that the lot is fulfilled. 9 TAS 3000-2009 Table B.1 Primary Sampling for Containing Container with Weight Not Exceeding 1 kg. (Section B.2.1) Size of Lot Size of Sampling (Units of Containers) (Units of Containers) Not exceeding 500 10 500 – 1,000 15 More than 1,000 20 Table B.2 Primary Sampling for Containing Container with Weight Exceeding 10 kg. (Section B.2.1) Size of Lot Size of Sampling (Units of Containers) (Units of Containers) Not exceeding 10 2 11 – 50 3 50 – 100 5 More than 101 7 Randomly take the primary sample (Section B.2.1) and send to inspection unit for quality analysis. For the analysis of contaminant and pesticide residues, it shall be in compliance with the sampling procedure under the relating agricultural commodity standards. B.3 Method of Secondary Sampling Sampling procedure for containing container with capacity of not exceeding 1 kg If the container’s weight is less than 200 g, the sample size for microbiological analysis shall be drawn according to Section B.3.1.1 without opening the container/box to obtain the specified number of sample. If the container’s weight is more than 200 g, the sample size for microbiological analysis shall be drawn according to Section B.3.1.1 without opening the container/box to obtain the specified number of sampling or the randomly sampling in each container for microbiological analysis by using suitable instrument to obtain the specified number of sample. TAS 3000-2009 10 Subsequently, take the remaining primary samples, thoroughly mix them, and sample to obtain sufficient weight for other quality analyses. If the sample is not adequate for the analyses, take more samples from the primary sample until sufficiency. Sampling procedure for container’s weight exceeding 10 kg and for container’s weight exceeding 1 kg but less than 10 kg First, randomly take the sample in each container for microbiological analysis by using suitable instrument to obtain the specified number of sample. Then, randomly sample in each container, thoroughly mix to obtain sufficient weight for other quality analyses. B.3.1 Microorganism (Section 8.2) B.3.1.1 Randomly sampling 5 samples from the primary sample (Section B.2.1). Each sample shall not be less than 150 g, contained in sealed condition before sending for microbiological analysis. B.3.1.2 If the result of the examination is in accordance with Section 8.2, it shall be considered that the lot is fulfilled. B.3.2 General Characteristics and Foreign matters (Section 4.1 and Section 4.3) colouring and flavouring (Section 5) B.3.2.1 Randomly sampling 300 g of mulberry tea from primary sample (Section B.2.1) for the analysis of general characteristics, foreign matters, colouring and flavouring. B.3.2.2 If the result of the examination is in accordance with Section 4.1, 4.3 and 5, it shall be considered that the lot is fulfilled. B.3.3 Moisture content (Section 4.2) B.3.3.1 Randomly take 2 samples weighs 50 g each, from primary sample (Section B.2.1)put into individually sealed containers for further examination of moisture content. B.3.3.2 If the result of the examination is in accordance with Section 4.2, it shall be considered that the lot is fulfilled. 11 TAS 3000-2009 Annex C UNIT The unit and symbol used in this standard and the SI unit (International System of Units or Le Système International d’ Unités) recognized to be used are as follows: Description Unit Name Unit Symbol Mass Gram g Kilogram kg Length Millimeter mm Volume Milliliter ml
