Raw materials: Raw materials are Myxopyrum smilacifolium Blume root that are not moldy Before using for next step of process, all dirt, soild, orgarnism and other objecst must be taken away - Drying: Myxopyrum smilacifolium Blume root will be dried at 45oC to reach the moisture of 10 - 13% so that the raw materials will not be moldy in the process of not being used - Cutting: The roots of Myxopyrum smilacifolium Blume are cut to slice of 1cm With this size of material, it is easy to absorb the solvent, the process of solvent injection is also faster, the active ingredients quickly dissolve in the solvent - Soaking and extracting: Materials are soaked in alcohol 80% solvent, extraction temperature is 800C, raw material/solvent ratio is 1/15 (kg/litter) and extraction for 90 minutes The obtained extracts are collected and prepared for the condensing step Soaking the of Stevia and Licorice materials in a temperature of 40 - 45oC, for hours, in 70o alcohol to get Stevia and Licorice extract - Condensing the extracts: The purpose of condensing is to remove solvent to increase the dry matter content of the product When it becomes a thick, viscous form, a liquid extract is obtained and ready for the next drying process - Drying liquid extracts: The liquid extracts will be dried to reach the moisture of - 10% - Grinding: After drying the solid extracts are very firm and very difficult to mix with addtive components, so it is necessary to grind them to powder form - Mixing: Three extract powders from Myxopyrum smilacifolium Blume, Stevia and Licorice and lactose will be mixed following the ratios of 11.4/0.3/0.3/88% respectively The mixture is mixed well to ensure the harmony of taste - Drying: The purpose of this drying step is to reduce the moisture of the final products to - 5% The temperature of 450C will be applied to get safe humidity and for better preservation - Packing: The mixed and dried extracts will be weighed and packed in a certain unit Ash and moisture contents of complete instant tea product 40 Luan van Table 4.8 Ash and moisture contents of complete instant tea product Number Content Result (%) Moisture 2.38% Ash 0.49% The Table 4.8 shows that the ash and moisture components of final instant tea product meet the requirement of standard of instant tea following the TCVN for instant tea products 41 Luan van PART V CONCLUSIONS AND RECOMMENDATION 5.1 Conclusions From the results of the research, there are some conclusions as follows: - During the extraction process of Myxopyrum smilacifolium Blume, the most suitable factors to have the highest amount of total polysaccharides content are: + Solvent is alcohol with the concentration of 80% + Time of extraction process is 90 minutes + Temperature of extraction process is 80oC + Ratio of material/solvent is 1/15 (w/v) - The mixing ratio of ingredients to create instant tea from Myxopyrum smilacifolium Blume was determined with 11.4% Myxopyrum smilacifolium Blume, 88% Lactose, 0.3% Licorice solid extract and 0.3% Stevia solid extract - The drying temperature of instant tea was determined with the temperature of 45oC - The final instant tea product has the ash component of 0.49% and the moisture of 2.38% 5.2 Recommendation - The process of producing instant tea from Myxopyrum smilacifolium Blume root should be applied in the real market to enhance the values of Myxopyrum smilacifolium Blume - It is very necessary to evaluate the bioactiveness of total polysaccharides obtained from the extraction process 42 Luan van REFERENCES I Vietnamese referencess: Đỗ Huy Bích, Đặng Quang Chung, Bùi Xuân Chương, Nguyễn Thượng Dong, Đỗ Trung Đàm, PhạmVăn Hiền, Vũ Ngọc Lộ, Phạm Duy Mai, Phạm Kim Mân, Đoàn Thị Nhu, Nguyễn Tập, Trần Toàn (2006), 1000 thuốc động vật làm thuốc Việt Nam, Nxb Khoa học Kỹ thuật, Hà Nội Hồng Văn Hộ (2006), Những có vị thuốc Việt Nam, Nxb trẻ Bùi Hồng Quang, Vũ Tiến Chính (2011), “Những lồi sử dụng làm thuốc họ Nhài Việt Nam”, Báo cáo Hội nghị khoa học toàn quốc sinh thái tài nguyên sinh vật lần thứ 4, tr.1260 Phạm Hoàng Hộ (2000), Cây cỏ Việt Nam Quyển II, NXB Trẻ, tr 889 Võ Văn Chi (2012), Từ điển Cây thuốc Việt Nam (Bộ mới), tập 2, NXB Y học, tr.369 Nguyễn Viết Thân (2003), Kiểm nghiệm dược liệu phương pháp hiển vi tập 1, NXB Khoa học kỹ thuật, Hà Nội Bộ Y tế (200), Dược điển việt nam IV, NXB Y học Đỗ Huy Bích (2004), Cây thuốc động vật làm thuốc Việt Nam, Nxb KH & KT, Hà Nội Đỗ Tất Lợi (2001), Những thuốc vị thuốc Việt Nam, NXB Y học Trương Hương Lan đồng đội (2014) nghiên cứu xác định thành phần dinh dưỡng cỏ TS Bùi Xuân Đông (2004), “Hóa sinh phần III”, Trường đại học Bách Khoa Đà Nẵng Lê Thanh Mai, Nguyễn Thị Hiền, Phạm Thu Thủy, Nguyễn Thanh Hằng (2005), “Các phương pháp phân tích ngành công nghệ lên men”, NXB khoa học kỹ thuật Đỗ Tất Lợi (2004), Những thuốc vị thuốc Việt Nam, NXB Y học Phạm Hoàng Hộ, Cây có vị thuốc Việt Nam, NXB KHKT Hà Nội Nguyễn Kim Phi Phụng, Phương pháp cô lập hợp chất hữu cơ, NXB Đại học Quốc Gia TP Hồ Chí Minh ( 2007), tr 35-36 Lê Ngọc Thụy (2009), Các q trình cơng nghệ sản xuất thực phẩm, Nxb Bách Khoa, Hà Nội Hà Duyên Tư (chủ biên) (2009), Phân tích hóa học thực phẩm, Nxb Khoa học Kỹ thuật, Hà Nội 43 Luan van II English references Jolly Samu, Siju E.N., Minil M and Rajalakshmi G R (2015), “ Antioxidant activity of Myxopyrum Smilacifolium lume”, Asian Journal of Pharmaceutical and Clinical Research, 8(3) Gopalakrishnan S., Rajameena R (2013), “GC-MS analysis of some bioactive constituents of the leaves of Myxopyrum serratulum A.W.Hill”, International Journal of Advanced Research Praveen R.P and Ashalatha S N (2014), “Callus induction and multiplication of internodal explants of Myxopyrum smilacifolium Blume”,International Journal of Current Microbiology and Applied Sciences, 3(10),pp 612-617 Chandrasekar R and Chandrasekar S (2017), “Natural herbal treatment for rheumatoid arthritis -
