本标准适用于乳与乳制品的微生物学检验。
本标准规定了双歧杆菌(Bifidobacterium)的鉴定及计数方法。本标准适用于双歧杆菌纯菌菌种的鉴定及计数。本标准适用于食品中仅含有单一双歧杆菌的菌种鉴定。本标准适用于食品中仅含有双歧杆菌属的计数,即食品中可包含一个或多个不同的双歧杆菌菌种。
本标准规定了低聚糖的术语和定义、分类、命名方法、技术要求、试验方法和标签要求。本标准适用于以天然产物或其转化物为原料,经酶法、酸碱法转化或直接提取工艺制成的液态或固态(粉末状、结晶状)食用或饲用低聚糖产品。
本标准规定了食品加工用乳酸菌的术语和定义、分类、要求、试验方法、检验规则和标志、包装、运输、贮存。本标准适用于以适宜的发酵用营养物质接种乳酸菌种,经发酵培养,浓缩等工艺制成的,用于乳及乳制品、肉制品、饮料、泡菜发酵及发酵剂以外的其他用途的食品加工用乳酸菌。
本标准规定了可用于食品的双歧杆菌属(Bifidobacterium)、乳杆菌属(Lactobacillus)和嗜热链球菌(Streptococcus thermophilus)鉴定技术的实验室基本要求、生物安全与质量控制、鉴定原则和鉴定结果表述。本标准适用于可用于食品的双歧杆菌属(Bifidobacterium)、乳杆菌属(Lactobacillus)和嗜热链球菌(Streptococcus thermophilus)的种水平鉴定。
本标准规定了食品微生物实验室常用的菌种保藏的定义、技术原则、技术要求和技术方法。本标准适用于食品微生物实验室菌种的保藏。
本标准界定了进出口食品、化妆品一般术语、制抽样术语、感官检验方法术语、理化检验方法术语、生物学检验方法术语、毒理学术语、风险分析术语、质量管理体系术语、出入境监督监管术语、标准术语、缩略语。本标准适用于进出口食品、化妆品标准的编写和出版,也适用于食品工业生产、科研、教学及其他有关领域。
This International Standard specifies a method for determining the minimal inhibitory concentration (MIC) of aseries of antibiotics applicable to bifidobacteria and non-enterococcal lactic acid bacteria (LAB).NOTE Unlike the disk diffusion method, which is semi-quantitative, the frequently used broth microdilution methodgives quantitative MICs of the test organism in a dilution series of the antibiotics. The lowest concentration of an antibioticthat prevents visible growth of a test organism is considered to be the MIC.This International Standard recommends the broth microdilution method as the standard method.
This International Standard specifies a method for the selective enumeration of presumptive bifidobacteria inmilk products by using a colony count technique at 37 °C under anaerobic conditions.The method is applicable to milk products such as fermented and non-fermented milks, milk powders, infantformulae, and starter cultures where these microorganisms are present and viable, and in combination withother lactic acid bacteria. (For proposed quality criteria of dairy products, see, for example, Codex Stan243:2003 [6].)Bifidobacteria used in milk products usually belong to the species (e.g. see References [7][8][16]):a) Bifidobacterium adolescentis;b) B. animalis subsp. animalis;c) B. animalis subsp. lactis;d) B. bifidum;e) B. breve;f) B. infantis;g) B. longum.
This Report only deals with the sharing between IMT-Advanced and the radiolocation service in the bands 3 400-3 700 MHz, including potential interference mitigation techniques which may be applicable for IMT-Advanced and the radiolocation systems. The sharing between the fixed-satellite service and IMT-Advanced is addressed in a separate Report.
This amendment provides the G.992.1 revision (revision of Annex C, addition of Annex I and addition of Appendix V). It includes the changes introduced by G.992.1 (1999) Corrigendum 2. Revised Annex C covers specific requirements for an ADSL system operating in the same cable as ISDN as defined in Appendix III/G.961. Annex I covers ADSL system with improved performance on short loops operating in the same cable as TCM-ISDN as defined in Appendix III/G.961.
This European Standard defines general rules for the enumeration of probiotic bifidobacteria in feed samples (additives; premixtures and feeding stuffs) that contain bifidobacteria as a single bacterial component or in a mixture with other microorganisms.
This Standard specifies a method for the selective enumeration of presumptive bifidobacteria in milk products by using a colony count technique at 37 °C under anaerobic conditions.
