生产精油和抗氧化剂用迷迭香干叶标准的研制

Study on Standardization of Dried Leaves of Rosemary for Production of Essential Oil and Antioxidant

根据行业要求,研究和制定了林业行业标准——生产精油和抗氧化剂用迷迭香干叶。该标准主要规定了迷迭香干叶的术语和定义、技术要求、取样、检验方法、包装、标志、贮存和运输等,技术要求中包含外观、气味和风味、迷迭香茎秆含量、迷迭香棕色叶含量、外来物含量、水分含量、总灰分、酸不溶性灰分、挥发油含量、醇溶抽提物等技术指标,该标准适用于各种干燥方法得到的迷迭香干叶,可作为迷迭香精油和抗氧化剂生产用原料质量评价及贸易的依据。根据采样测试和结果分析,建议将迷迭香干叶设为3个等级,即优级品、一级品和二级品,并规定了3个等级迷迭香干叶技术参数的取值范围。

Standardization of dried leaves of rosmary （Rosmarinus officinalis L. ） was studied to establish a professional standard according to the requirement of rosmary processing industry. The standard specified terms and definition, technical requirements, sampling, testing method, packing, marking, storage and transportation. The technical requirements included items such as： appearance, odour and flavour, content of broken stems and branches of rosemary, content of brown leaves of rosemary, content of extraneous matter, moisture content, total ash, ash insoluble in hydrochloric acid, volatile oil content and extract soluble in ethanol. The standard could be used for dried leaves of rosmary obtained by different drying methods. The standard will be acted as a basis for quality evaluation and trading of dried rosemary leaves as raw material for production of essential oil and antioxidant. It is suggested to set three grades of dried rosemary leaves, namely ： excellent grade, the first grade, and the second grade according to the testing results of rosemary samples. The value ranges of technical parameters for three grades of dried rosemary leaves were also specified.
