Application of food additives the rapid development of modern food industry requires more and more strict food safety, and natural food additives are more and more used in the food industry. |
| extraction process | 1. Supercritical CO2 fluid extraction: 160.0G of the crushed and sieved rosemary powder is placed in a 1L extraction kettle, and the extraction time is designed with the oil yield as the index, extraction pressure and extraction temperature of three factors and three levels of orthogonal experiments. This was repeated twice and the arithmetic mean of the results was taken. The optimum conditions are: extraction pressure 20.0MPa, extraction temperature 40.0 ℃, extraction time 4.0h, the oil yield reached 4.40%;2. Steam distillation: 20.0G of the crushed and sieved rosemary powder is placed in a 500ml round-bottom flask, and the particle size of the material is designed with the oil yield as an indicator, the orthogonal experiment of three factors and three levels of liquid-solid ratio and extraction time was determined according to the determination method of volatile oil XD in the appendix of Pharmacopoeia of the People's Republic of China (2000 edition 1), repeated for 3 times, and the arithmetic mean value was taken as the result. The optimum conditions were as follows: the material particle size was 0.20, the ratio of liquid to material (v/w) was 4 ∶ 1, the extraction time was 4.0h, and the oil yield reached 1.40%. |
| content analysis | ester content analysis a sample of 10ml was accurately measured by the ester determination method (OT18). The equivalence factor (e) in the calculation is taken as 98.15. The ester content in terms of bornyl acetate was thus determined. Total borneol content analysis was determined by total alcohol assay (OT-5). 5ml of dry acetylated oil should be taken accurately During saponification. The percentage content of Borneol (calculated by the following formula: X = 7.712A(1-0.0021E)/(B-0.021A) where A- volume of hydrochloric acid of 0.5mol/L for titrating sample solution (ml) and the difference between the blank test consumption; B a quality of the acetylated oil, g;E a bornyl acetate (C12H20O2) ester content,% (see above). |
| toxicity | GRAS(FEMA;FDA,§ 182.10,2000). GRAS; (FEMA;FDA,§ 182.20,2000). LD505000mg/kg (rat, oral). |
| usage limit | FEMA(mg/kg): Soft drink 3.6; Seasoning 2.9; Meat 40; Candy 7.5; cold drinks 0.5~40; Baked products 6.3. FEMA(mg/kg): Soft drink 700; Seasoning 680; Meat 380. |
| Use | GB 2760-96: food flavor permitted. Mainly used for sauce, meat, poultry and other seasoning. light yellow liquid aroma/taste: Strong cool, sharp and fresh herb with orange fruit aroma, sharp, spicy, strong aroma, transparent hair, giving people a sense of freshness. Site of use: whole plant (removal of the woody part), or only leaves. Specific gravity: (20 ℃)0.893-0.916 optical rotation: (20 ℃)-7o-+11o30 'refractive index: (20 ℃)1.4670-1.4730 acid value:<1 Solubility: 1:4-1:10 dissolved in 80% ethanol ingredients: α-pinene, camphene, cineole, bornyl acetate, camphor, borneol content: borneol 10 ~ 15% application: rosemary oil is often used as a health and medical supplies, not used in daily flavor. Medicinal qingrejiedu powder |
| production method | produced by the perennial shrub Rosmarinus officinalis the fresh shoots and flowering annual shoots and flowers were distilled by steam. Yield 2%(leaves) ~ 1.4% (flowers). Mainly produced in Spain, Italy, Tunisia, the former Yugoslavia, the former Soviet Union and Turkey and other countries. More use of leaves or in addition to the xylem of the whole plant, should be quickly dried after harvest, so as not to dissipate aroma. The drying was performed in a large dish in a ventilated dark place to maintain the green color. |
