绪论：
This is particularly important for a food engineer since the commercial advantages of an optimal controlled process include it can provide better product quality and lower costs compared with an uncontrolled process.
这点对于食品工程师来说是非常重要的，因为商品化生产中，优化控制的加工过程与一个非控制的加工过程而言，具有产品品质高，生产费用少的优点。
The food technologist can usually recognize fats when he sees them because they are quite different both in their physical properties and in their chemical composition from the other two main food constituents, carbohydrate and protein.
当食品科学工作者看到脂肪时，通常可以确认他们，因为不论在物理性质和化学组成上，脂肪都与另外两种主要食品组成成分（碳水化合物和蛋白质）不同。
Computer control is the current by-word in fermentation technology and will soon reach the point where you dare not admit that your fermenters are not coupled to a computer; unfortunately, amidst the improvements this brings, we are beginning to see cases of the old dogma ‘instruments prevent creative thinking’
计算机控制是现代发酵技术中的常用语，并且很快你就不能容忍你的发酵罐没有被连接到计算机。不幸的是，在这过程中我们将开始看到旧的教条主义“仪器阻碍看创造性思维”
It is possible,particularly in the case of an empty fermenter,that a vessel under vaccum could be deformed by the external air pressure,but the main reason for avoiding pressure below atmospheric within the fermenter is that the non-sterile(未经灭菌的)air of environment could be drawn through any small leak in the welded seams of the vessel or pipeline,or through joints or valves.
在真空状态下的发酵罐，尤其是空罐，在罐外气压作用下，可能发生形变，但是避免罐压低于空气压力的原因，还是环境中未经灭菌的空气可能会从发酵罐及其管件焊缝的任何细微缝隙或通过连接件以及阀门吸入罐内。
