Can bamboo leaves be used as antioxidant food additives?

The efficacy and function of bamboo leaves and their medicinal value, taste and meridian tropism are sweet, mild, cold, clearing away heat and promoting diuresis in lung, gallbladder and stomach (1): it is used to treat sores in mouth and tongue, short urine and painful urine caused by excessive internal heat (urinary tract infection in China), and Akebia Akebia and Glycyrrhiza uralensis Fisch (Daochi Powder) clear away heat and promote diuresis, and treat fever, polydipsia and fright. Ophiopogon japonicus oral dose 6- 15g: fried bamboo leaf essence-bamboo leaf antioxidant, the weak ring of antioxidant in the structure of food additive industry in China, especially antioxidant. At present, the antioxidant effect of four kinds of paints abroad is obviously better than that of BHABHT rosemary extract, including sage extract, licorice antioxidant, catechin, ellagic acid and sunflower seed extract. At present, I only approve the use of several edible antioxidants, such as tea phenol, phytic acid (sodium), phospholipids and licorice antioxidants, to replace antioxidants. At present, the development trend of food industry has the characteristics of local resources, and independent intellectual property rights are practical, efficient and cheap. Antioxidants are more important. China has a vast territory and abundant resources, and there are thousands of traditional medicines and foods, which have unique advantages in developing nutritional and functional food additives. I, Su Zhuwang, said that there are 40 genera in China and about 4 million hectares of bamboo in Zhong Zhulin, and the unique characteristics, forms and uses have been paid more and more attention. The strategy of sustainable development is playing an increasingly important role. My research on bamboo leaf effect is at the leading level in the world-99 years ago, the research level of bamboo leaf flavonoids on lipid oxidation showed that the leaf extract of Phyllostachys pubescens significantly inhibited AAPH-induced lipid oxidation and prevented C++ serum low-density lipoprotein cholesterol oxidation. Wheat milk extract (Ahuatian) added with 1% bamboo leaf extract significantly improved the anti-free radical and anti-oxidation ability of the product and protected the fresh-keeping performance of the product; The enhanced quantification of beer improved the antioxidant capacity and storage stability of bamboo leaf extract, and significantly inhibited the increase of diacetyl. The controllable acid hydrolysis of bamboo leaf flavonoids significantly improved the lipophilicity of its flavonoid glycoside converted aglycone. The rapid determination of TBA showed that the hydrolyzed aglycone of rapeseed oil system showed oxidation resistance compared with BHT, and its effective concentration was about 0.2 ‰. The improved oven test showed that the ability of hydrolyzed aglycone to inhibit lard oxidation was similar to that of quercetin tea phenol. The results of chemiluminescence determination show that the aglycone after hydrolysis is clear. The properties of OH are close to quercetin, which indicates that bamboo leaf flavonoids have the potential as antioxidants. In 2000, Shuang Ye antioxidant was listed as a guide for the development of new products in domestic light industry by the State Economic and Trade Commission, and the summary of priority products in food additive industry was listed as 2002 items. "Hygienic Standard for the Use of Food Additives" requires a systematic study on the production technology, physical and chemical properties, quality standards, toxicological test results and application effects (application scope and application amount) of antioxidant (AOB) from bamboo leaves. 1. Production technology of Bambusoideae, Bambusoideae, Phyllostachys and Phyllostachys. Based on the original patented bamboo leaf crude extract, it is refined by combined membrane separation technology. Due to the progress of column chromatography and countercurrent chromatography, the content of total flavonoids in lactone phenolic acids is lower than or equal to the compound synergistic mixture mentioned in this product. The main flavonoid glycosides of flavonoids include orientin, isoorientin, vitexin isovitexin, etc. Lactones are mainly hydroxycoumarin and its glycosides; The main cinnamic acid derivatives in phenolic acids are chlorogenic acid, caffeic acid and ferulic acid. 3. AOB for identifying yellow or brownish yellow powder or particles is soluble in water and ethanol, and slightly soluble in acetone, butanol, ethyl acetate, etc. Identification of AOB hygroscopic dry-phase stabilizer: take 0.5g of this product and dissolve it in 95% ethanol 100ml. According to the identification, take this solution 1ml and add 2-3 drops of1%FeCl triethanolamine solution, which should be dark blue or blue purple; Take 1ml solution and add 1% %AlCl triethanol solution, the solution should be bright yellow; Take 0.5g of this product, add ether 10ml for ultrasonic extraction for 30s, filter the filtrate, smear 1ml in a water bath at 0 ~ 90℃, and evaporate the ether. Add 2ml of 2% m-dinitrobenzene solution (prepared with 95% ethanol) and 2.5mol/LKOH aqueous solution of 1ml, put them in a hot water bath, and they will turn red immediately and dark purple quickly. The infrared spectra of potassium bromide tablets show 3-4-0, 2-9-0, 1-5-2-0, and the characteristic absorption is near 0 bar, 0cm- 1 grade. It is dissolved in pure methanol with the spectral range of 200 ~ 200 nm. The scanning ultraviolet spectrum shows that there are two main absorption peaks in the region of 240 ~ 400 nm, and the strong absorption peak in the region of 240 ~ 240 nm shows the typical characteristics of plant flavonoids preparations. 4. Safety evaluation of bamboo leaves, history of edible medicine in China and even Southeast Asia. 99 Ba (light) bamboo leaves have been approved by the Ministry of Health to be included in medicines and foods. User list: Bamboo Leaf Flavonoids and Zhukangning Capsules, which obtained the approval number of health food in 1999 and 2002 respectively, and the disease prevention and control in Zhejiang Province was carried out in accordance with the Food Safety Toxicology Evaluation Regulations of the Ministry of Health. The research conclusion shows that in the first stage, according to China's toxicity grading standard, at the weight of 10000 mg/kg, the LD50 of China and the oral toxicity of mice were identified as the actual viruses in both sexes. In the second stage, Ames test was negative, and the micronucleus test of mouse bone marrow cells was negative, suggesting that in the third stage, the low dose group, high dose group and low dose group were set as 100, 200 and 300 times of energy intake (Balu 0 mg/d). The traditional teratogenic test showed that all the indexes in each dose group had no obvious maternal toxicity and teratogenic effect. There was no obvious toxic reaction in maternal effect and fetal effect of mouse offspring reproduction test. Metabolic test showed that four kinds of carbon glycoside flavonoids of AOB were directly absorbed in the gastrointestinal tract of rats, and all major tissues and organs (liver, kidney, brain and muscle) were treated for 0.5h, 1h, 1h, 1h, 2h, 3h, 4h, luh, bahh and/kloc-. The yield and content of four kinds of carbon glycosides in gastrointestinal tract are different. After 24 hours of sexual gavage, fecal samples accounted for two kinds of paints, AOB samples were not excreted by land% urine, and other main hydroxycoumarins were absorbed mainly through blood channels. Blood and kidney tests were carried out in liver, brain and muscle tissues of all rats. Give the subject 24 hours. The efficacy of urine test in this group was 1.9%. Introduction to the efficacy of bamboo leaves: Bamboo leaves ("Bielu") are different from Bambusa bambusa ("Bielu"). The morphology of bamboo is described in detail. Bamboo shavings are collected by fresh people. The leaves of herbs are narrow-lanceolate. 5 ~ 1.6 cm wide and 1 ~ 2 cm wide. The tip is tapered, the base is obtuse, the petiole is about 5 mm long, and the edge is smooth on one side and serrated on the other. Parallel pulse Lu ~ Ba transverse pulse is very significant; Dark green hairs on the leaves, shallow on the back and slightly hairy at the base; Thin and crisp, weak in qi, pale in color, green, complete, branched, delicious, sweet and light in cold ① turtle shell: pungent and flat in cold ② medicinal property theory: sweet and toxic ③ green and burning herbs: bitter and sweet but slightly cold in poison ④ herbs: sweet and light in flavor, flat in qi, slightly cool in channel tropism, lung, gallbladder and stomach meridian ① southern Yunnan herbs: entering. Indications of muscle three meridians-bamboo leaves have the functions of clearing away heat, removing annoyance and promoting diuresis, and treat fever, polydipsia, convulsion, epilepsy, cough, vomiting, vomiting, short face and chylous tongue sore. ② Theory of medicinal properties: treating hematemesis, fever, toxic wind and thirst; 3 dietotherapy materia medica: treating cough, thirst, phlegm blocking throat and removing annoyance; ④ Traditional Chinese medicine: resolving phlegm to treat heat and mania ⑦ Herbs: treating asthenic heat, irritability, sleep, polydipsia, body fluid, hydrolysis, laryngitis, wind-heat convulsion ⑧ Chongqing Tang essays: soothing the liver, promoting gallbladder, expelling wind, clearing heat, calming the nerves and stopping spasm ⑨ Herbs: cooling spleen, treating hematemesis, nosebleeds, hearing and improving eyesight, oral dosage. Three or two liters of wheat, three liters of Trichosanthes kirilowii, two cups of water, two buckets of boiled bamboo leaves, eight liters of herbs, four liters of warm-taking (the secret of bamboo leaf soup outside Taiwan), two liters of gypsum for treating typhoid fever, one liter of Pinellia ternata (washed), half a catty of people, one liter of Ophiopogon japonicus (roasted licorice), two liters of rice from Treatise on Febrile Diseases, and half a liter of bamboo leaf gypsum. (4) Treatment of wind-heat by trance: Bamboo leaves hold half a cup of rice and two cups of wormwood, and cook two flavors; Take a juice cup; Rice is put into porridge ("Sheng Hui" bamboo leaf green porridge); (5) Treating wind-heat red asthma pain: Bamboo leaves, Radix Puerariae, Radix Saposhnikoviae, Radix Platycodi and Radix Glycyrrhizae, and Ginseng Second Artillery; Fifteen dates, five ginger and twenty flavors are boiled in a barrel; Take two liters and a half warm three warm clothes to sweat (synopsis of the golden chamber) licorice. Take two glasses of water and take them to seven cups of warm clothes (Qi Xiaoliang's Danzhu decoction). ⑦ Treat the pain caused by heat in the intestine: Danzhu decoction, Erqianmu Tongqiao Gancao Bache (fried), San Qian Huangliuqian decoction (Li Yi Jian Yi's Daochi powder). ⑧ Treat sudden sweating of blood gas: Danzhu decoction is taken three times and then taken (again).
