I: INTRODUCTION 1.1 Rationale: Currently, tea tree is not only a nutritious food crop for health but also a key crop in the sustainable poverty reduction of mountainous farmers and helping farmers improve their local economic situation in the establishment and development of the new countryside, being the place to develop tourism for many regions of the mountainous and midland regions Green tea - a familiar and long-standing drink, has widespread popularity around the world According to modern scientific researchers, green tea contains many healthy chemical compounds such as: Polyphenols - catechins, caffeine, amino acids These are substances that work to increase resistance, keep the body healthy, reduce stress, fight aging, cut the risk of heart and cancer disease… When the tea is diluted, water can only partially extract the valuable antioxidants as well as minerals, most of the nutritional value is in the residue that people often throw away On average, a cup of matcha is equivalent to 10 cups of regular brewed green tea [20] Commonly, matcha is divided into types of matcha powder: matcha is for drinking, matcha for cooking, and for cosmetic use Matcha for drinking is the original use of matcha, being a tea with a natural aroma, having a mild acrid taste and is selected from young leaves, with high prices In addition, this matcha powder can be used in cosmetics with a variety of uses Matcha for cooking has a strong flavor, often using older tea leaves, maximizing the use of ingredients, often cheaper than drinking matcha The production of matcha diversified Luan van products from tea leaves and can be used in many products of the food and pharmaceutical industries From the above reasons, I have chosen the topic: “Survey of Matcha green tea powder process at Ntea Viet Nam J.S.c in Dong Hy- Thai Nguyen” 1.2 Objectives: - Surveyed matcha green tea powder production process at Ntea J.S.c in Dong Hy- Thai Nguyen - Surveyed the standards applied for

Biocert-IFOAM certification 1.4 Profile of the cooperating agency: The company name: Ntea Viet Nam J.S.c in Dong Hy- Thai Nguyen Legal representative: Nguyen Kim Cong Operating date: 11/10/2017 Luan van Step 3: Assessing the current status of food manufacturers against the requirements of standards: It is important to consider the activities, consider the requirements and extent of the food manufacturer’s response This assessment is the basis for planning human resources that need to be changed or supplemented Thereby, the company builds detailed programs and projects to ensure control of food safety hazards at all times when consumption Benefits of ISO 22000: 2005: - Achieved ISO 22000: 2005 certification, allowing companies and businesses to compete in international markets In the domestic market, this can help the company stay one step ahead of its competitors - Thanks to a systematic approach, risks are controlled more efficiently, quickly, and flexibly - Since the risk points are pre-defined, production defects should be avoided, thereby reducing production costs - Food poisoning is completely prevented - All consumer food safety needs are fully met - Everyone working in the organization is aware of food safety and hygiene issues - Control inventory more effectively - Delivery time is done exactly - Guaranteed consumer satisfaction from which to get their trust 48 Luan van Figure 14: ISO 22000: 2005 certification Every product put into production is required for quality, quantity; regardless of the error, it must be fully recorded and investigated to find the cause and the way to be handled After quality inspection meets new standards, it will be delivered to consumers 49 Luan van For each factory, there is always a QC department - which helps to check the quality step by step in the production process This department inspects the sampling, checks the starting materials, packaging materials, and controls all production stages Figure 15:

International Federation of Organic Agriculture Movement with 870 members in 120 countries Founded in 1972 in France in a conference on organic agriculture organized by the French farmer organization [8] The organic industry has undergone extraordinary changes in phases: Organic 1.0, Organic 2.0, and Organic 3.0 Organic 1.0: Pioneers from around the world Organic 1.0 was started by numerous pioneers, who observed the problems with the direction agriculture was taking at the end of the 19th century and beginning of the 20th century They saw the need for a radical change[17][9] Organic 2.0: Norming and Performing: There is more and more evidence highlighting the positive impacts of organic on a range of important issues including consumer health, biodiversity, animal welfare and the improved livelihoods of producers[17][9] Organic 3.0: Approved by our General Assembly in 2017, the overall goal of Organic 3.0 is to enable a widespread uptake of truly sustainable farming systems and markets based on the principles of organic agriculture[17][9] IFOAM standards are applicable in the fields of: agricultural production (including plant varieties), livestock (including beekeeping), aquaculture, wild animals, food processing[ 8] Purpose: - Applied the principle of organic agriculture on ecological, economic and social factors of the world 51 Luan van - Allows for widespread adoption of truly sustainable farming systems and markets based on organic principles and imbued with a culture of innovation, improving progress towards best practices, transparency integrity, comprehensive collaboration, overall system and real pricing [17] Mission: - Lead, unite and support the organic farming movement Value: - IFOAM holds an important position as the international organization of the organic world, uniting stakeholders from all aspects of the industry to create a common voice on organic issues - IFOAM operates fairly, comprehensively, with the participation and appreciation of other organic agricultural movements In the process of implementing the goals, IFOAM proceeds to implement courses, sticking to organic agriculture movements based on principles Support ecological and social change to facilitate trade, production, support organic development and train the next generation of leaders [8] 3.7.3.2 IFOAM standards are applied in Ntea Thai Nguyen: Land and water: Be tested periodically every months Fertilizer: The Company does not use chemical fertilizers in organic production, chemical plant protection drugs, growth stimulants, does not use human manure, and compost is made from municipal waste 52 Luan van Agricultural residues and animal manure took from outside the farm must be heated and decomposed before being used in organic farming Cultivar: The factory uses the locally available midland tea garden for renovation, sufficient to adapt to local soil, climatic conditions, and resistance to pests and diseases Maintained and managed organically for 12 - 36 months before being certified organic Management of pests, diseases, and weeds: Always comply with IFOAM standards for substances used to control harmful microorganisms and disease Pests, diseases, and weeds are always prevented before the breeding season Pests: Mold is controlled by Ntea in rainy seasons, before the rainy season, water nano silver to control fungus Watering garlic lemongrass chili herb to prevent pests, bugs, mosquitoes, During the breeding season can often water herbs (once every days), when many worms appear, we proceed to catch them manually Weed: we need to remove weeds at the base of the tea to be able to protect the base of the tea plant from damage and from weed competition for nutrients Raw material preservation: Store ingredients in a cold room of 16 ° C, placed on a shelf at least 10cm away from the floor Avoiding mold, avoid water entering the material storage, always keep dry and clean Ntea Thai Nguyen Joint Stock Company is honored to be the first unit in the Vietnam Tea Association to be directly visited and awarded by Biocert 53 Luan van International (India) and awarded international organic certification for its achievements in production and business activities according to the standards of organic agriculture in IFOAM (International Federation of Organic Agriculture Movements) [1] According to Dr Dilip Dhaker- representative of Biocert International, the organization highly appreciated the results that Ntea Vietnam has achieved In addition, Ntea's natural conditions, soil resources, water resources, and primary products, etc., have undergone a series of rigorous tests and scientific analysis according to international standards expert review [1] Figure 16:International organic certification issued by Biocert International 54 Luan van Ntea branded products always meet the standards of a prestigious organic agricultural organization This is considered a "travel" license to help Ntea boost exports while promoting the image of the country and people of Vietnam as well as affirming the brand and quality of Vietnamese products 55 Luan van CHAPTER IV DISCUSSION AND LESSON LEARNED 4.1 DISCUSSION There are a lot research on matcha, application of matcha in food and functional foods However, counterfeit products are increasingly appearing on the market that not meet international quality standards The purpose of this thesis is to survey the production process of organic green tea powder at Ntea Thai Nguyen Joint Stock Company Matcha is an organic product so the manufacturing process must be strictly followed from cultivation to finished products Steaming and crushing are two particularly important steps because it affects the quality, taste and color of matcha The manufacturing process of matcha organic green tea powder at Tea meets all quality standards Matcha Ntea is economical price but the quality of the product is highly appreciated, there is not too much difference from Japanese matcha products Matcha Ntea organic green tea powder is used in two forms of beverage and beauty Basically Matcha is used as a beverage, with more attention with popular forms: hot drink, cold drink and ice cream Moreover, Ntea Thai Nguyen also produces in milk tea products with matcha ingredients and received a lot of positive feedback from consumers This is seen as an advantage that brings the company on the momentum of development and retains a foothold in the tea industry at domestic and international Ntea Thai Nguyen always aims to bring consumers a

improving myself so that I can adapt to the risks that may occur in a more professional working environment in the future 57 Luan van CHAPTER V CONCLUSION After my internship at Ntea Thai Nguyen company from theory to practice through data collection by interviewing, observing and directly involved in production, I completed this thesis ―Survey of matcha green tea powder process at Ntea Vietnam J.S.c in Dong Hy, Thai Nguyen‖ and solves the following important issues: First, I research clearly the process of processing Matcha green tea powder at Ntea Thai Nguyen from care to finished products In the process of directly participating in production, from a student perspective I realize that in order to create a qualified organic green tea powder product, it is necessary to go through strict steps and regulations in production Second, assess the factors affecting the accumulation of some chemical compounds in tea and factors affecting the change of chemical compounds of tea during processing On that basis offer solutions to improve the quality of tea products in the future Ntea Thai Nguyen Joint Stock Company completely meets the requirements of quality products such as food hygiene and safety, storage system The factory has applied ISO 22000:2005 standards to the processing stages to ensure safety and hygiene Moreover, the company is also honored to be a unit in the

With maxim ―Taking quality as a competitive advantage, customer satisfaction is a measure of value‖, Ntea Thai Nguyen has a 58 Luan van policy of a closed production process that meets organic standards, confidently brings consumers high-quality organic products However, the company has not yet operated at full capacity, not fully automated, still needs the help of many workers There should be some orientation to overcome problems with production equipment and improve the quality of machinery There are more progressive solutions to solve external problems for product productivity which achieve the best effect 59 Luan van REFERENCES I Vietnamese references: Documents circulated internally by Ntea Vietnam company Dang Thi Thanh Quyen (2007) Research on green tea powder matcha
