| HACCP是一个完全的预防性食物平安质量掌握系统，请求熟悉如今还没有熟悉到的伤害加以掌握，警惺能够涌现的新伤害，一旦涌现立刻掌握。本研究应用HACCP(伤害剖析和症结掌握点)的根本道理对法国种特细青刀豆罐头的临盆进程停止伤害剖析并提出伤害的预防办法，肯定了症结掌握点，即法国种特细青刀豆罐头空罐(瓶)验收、装罐、排气和封口、杀菌、冷却等五个工序。本文重要研究法国种特细青刀豆罐头杀菌前提(杀菌温度和时光)这一环节。在杀菌的进程中，既要处理杀菌过度形成的产物的色、喷鼻、味欠安，同时也要处理杀菌缺乏形成的食物平安伤害，使罐头食物到达贸易无菌，既能在常温下储藏及发卖，又尽量的坚持食物原本的风味、光彩、组织形状及养分成份。是以，停止法国种特细青刀豆罐头杀菌前提的研究对进步产物品德，包管产物质量与平安显得极端主要，经由过程迷信的实验、剖析、验证，对杀菌前提等停止肯定，并停止了保温蕴藏试验，证明在症结掌握点上对明显伤害实行的进程掌握的有用性，为法国种特细青刀豆罐头平安临盆与品德包管供给迷信的实际根据。试验办法起首依据法国种特细青刀豆罐头的相干特征选定了罐头杀菌的对象菌为生芽孢梭状芽孢杆菌，肯定生芽孢梭状芽孢杆菌耐热性参数D值，实际盘算出杀菌前提(杀菌温度和时光)并停止实罐实验，依据产物的感官质量最好和经济上最公道选定杀菌前提。接着在罐内接种生芽孢梭状芽孢杆菌停止确证性接种实罐实验，确证杀菌前提的公道性，肯定最好杀菌前提。并对接种实罐实验后的试样在恒温下停止保温蕴藏实验。对接种实罐实验和保温蕴藏实验成果都正常的罐头加热杀菌前提进入临盆线的实罐实验作最初验证。临盆线实罐实验样品在恒温下停止保温蕴藏实验，当保温实验后开罐磨练成果，内容物全体正常，即为平安的杀菌前提，可在临盆上运用。研究结论以下(1)依据生芽孢梭状芽孢杆菌的耐热性，对法国种特细青刀豆罐头杀菌前提停止实际盘算，成果为杀菌温度121℃，时光22。52min(铁罐(≤800g))。经由过程正交实验并联合感官品德评价，肯定法国种特细青刀豆罐头实罐杀菌前提温度121℃，经由23min杀菌后，法国种特细青刀豆罐头的芽孢杆菌和耐热性细菌都可以获得有用的掌握。(2)接种生芽孢梭状芽孢杆菌作为目标菌(Clostridium sporogenes，简称(P。A。3679))，经由过程分歧的杀菌公式杀菌后肯定最好杀菌公式(15min—23min—15min)/121℃，仅限于铁罐(≤800g)。(3)接种实罐实验后的试样在恒温下停止保温蕴藏实验。在温度为35℃、36℃、43。2℃前提下，法语论文题目，分离蕴藏3个月，成果是容器外不雅无异常变更，罐底盖未收缩、无低真空。实验停止后对全体实验罐停止开罐磨练，对严厉依照各症结掌握限值停止加工的法国种特细青刀豆罐头，在保温蕴藏实验期内形状、光彩、PH值和稀薄性等目标都正常。(4)临盆线的实罐实验验证了最好杀菌前提温度121℃，时光23min(铁罐(≤800g))的平安性。(5)临盆线实罐实验样品在恒温下停止保温蕴藏实验，法语论文范文，在温度为35℃、36℃、43。2℃前提下，分离蕴藏3个月，实验进程中未涌现胀罐景象，保温实验停止后开罐磨练，成果是内容物全体正常，是以，验证的最好杀菌前提是平安的。 Abstract: HACCP is a complete preventive food safety quality control system, request is familiar with the present damage is not familiar with the master, the police the marsten house can emerge a new damage, once appear immediately grasp. This study uses basic principles of HACCP (crux of damage analysis and control point) of France a fine green concanavalin canned birthing to stop the damage analysis and put forward the measures to prevent damage, affirmed the crux to grasp the point, namely acceptance of French special fine green beans tin cans (bottles), tank, exhaust and sealing, sterilizing, cooling etc. five processes. The important research in the process of canned canned food sterilization conditions (sterilization temperature and time) of this link. In the process of sterilization, both to sterilization excessive formation of product color, nasal spray, taste Qianan, also have to deal with sterilization lack of food safety harm, the canned food to arrive trade sterile, both at room temperature storage and sale, and try to adhere to the food the original flavor, luster, shape of the structure and nutrient ingredients. Is to stop French special fine green beans sterilization of canned food premise of research to improve product quality, to ensure product quality and peace is extremely important, through the process of scientific experiment, analysis and verification, the sterilization conditions such as stop sure and stop the insulation hidden test. The crux of the master master of obvious damage to the implementation process of the usefulness of, for French special fine green concanavalin canned safe childbirth and moral guarantee supply superstitious actual according to. Test method first according to French special fine green concanavalin canned coherent features selected object bacteria sterilization of canned food for Clostridium spores, sure Bacillus Clostridium thermophilic Bacillus parameters D value, actual disk calculated sterilization premise (sterilization temperature and time) and stop the tank experiment, according to sensory quality of the product the best and most economically reasonable selected sterilization conditions. Then the bacteria were inoculated in the tank to stop the confirmatory inoculation experiment, and confirmed the rationality of the sterilization condition. And the experiment of the test sample after the experiment of the experiment was stopped under constant temperature. To actually inoculated pot experiment and insulation contains experimental results both normal canned heat sterilization conditions into the production line of tank experiment to verify the initial. Production line tank experimental samples under the condition of constant temperature stop insulation contains experimental, when incubation experiments can hone achievements, contents of all normal is safe sterilization conditions, and can be applied in production. Study the following conclusions (1) according to the heat resistance of spores of Clostridium, of French special fine green beans sterilization of canned food premise stop theoretical calculation. As a result, sterilization temperature of 121 DEG C time 22. (Tie Guan 52min (800g)). Through orthogonal experiment and sensory association moral evaluation, certainly French special fine green concanavalin canned can sterilization conditions temperature 121 DEG C, through 23min sterilization, French special fine green concanavalin canned bacillus and thermoduric bacteria can be useful to master. (2) sporogenes Clostridium (P) was used as the target bacteria (). A. 3679), through the different sterilization sterilization formula certainly the best sterilization formula (15min, 23min, 15min) /121 DEG C, only limited to tin (less than or equal to 800g). (3) after the experiment of the experiment, the experiment of the test sample was stopped under constant temperature. At a temperature of 35 C, 36 C, 43. 2 degrees Celsius, the separation of 3 months, the results of the container is no exception, no abnormal changes in the bottom of the tank is not contracted, no low vacuum. Experimental stop to stop all the cans can hone, tough in accordance with the crux of the master limit stop processing the French super fine green concanavalin canned, in the insulation hidden during the experiment of shape, luster, and the pH value of the thin target are normal. (4) canning production line experiment verified the best sterilization conditions temperature 121, time 23min (Tie Guan (800g)) security. (5) production line can stop insulation is experimental experimental samples under constant temperature, the temperature of 35 DEG C, 36 C, 43. 2 degrees under the premise, the separation of 3 months, the experimental process has not emerged in the phenomenon of expansion tank, heat insulation test after the opening pot test, the results are the contents of all the normal, is to verify the best sterilization premise is safe. 目录: |
