-------------------------------------------PU 值-------------------------------------------------
PU(巴氏杀菌单位)的计算核心是 “温度对微生物的杀灭效应×时间”的累积值,需结合特定温度下的杀菌效率系数(Z值或L值,行业常用Z值),具体分两步:
1. 明确核心参数
计算前需确定2个关键值:
• 参考温度与基准时间:默认以 60℃为基准温度,1分钟的杀菌效果定义为1个PU(即60℃×1分钟=1PU)。
• Z值:衡量温度对杀菌效率影响的系数,指“杀菌效率提升10倍所需升高的温度”。
啤酒行业通常取 Z=10℃
(不同食品Z值不同,如牛奶Z=8℃,啤酒因微生物特性取10℃)。
2. 套用计算公式
若杀菌过程中温度恒定(如恒温杀菌阶段),直接用以下公式计算:
PU = t × 10^[ ( T - 60 ) / Z ]
公式中各符号含义:
• PU:最终的巴氏杀菌单位总数;
• t:在温度T下的实际杀菌时间(单位:分钟);
• T:杀菌过程中的实际温度(单位:℃,需≥60℃,低于60℃时杀菌效应可忽略);
• Z:啤酒行业取10℃(固定值,除非特殊工艺调整)。
-------------------------------------------------------------------------------------
举例:直观理解计算过程
假设饮料在 70℃下恒温杀菌5分钟,计算PU值:
1. 代入公式:T=70℃,t=5分钟,Z=10℃;
2. 先算指数部分:(70-60)/10 = 1,10^1 = 10(10的多少次方)
3. 再算PU值:5分钟 × 10 = 50 PU。
即“70℃杀菌5分钟”的累积杀菌效果,相当于“60℃杀菌50分钟”,最终得50个PU。
------------------------------------------------------------------------------------------------
啤酒 PU值
啤酒杀菌一般63度15分钟,杀菌微生物,酵母菌,乳酸菌,一般在 15-30之间
(取杀菌效率系数 Z=10℃)
牛奶PU值
一般 63-65度 保持30分钟 PU值 157-320之间
如果用72-75度 15秒杀菌 约为 15-36左右
高温杀菌80-85度 保持 10-15秒 PU值更高
(取杀菌效率系数 Z=8℃)
果汁PU值
一般情况多数在 90-95度 10-15分钟
果汁 85度 15分钟 PU值约为 1320
果汁 90度 15分钟 PU值约为 33950
果汁 95度 15分钟 PU值约为 116145
果汁特殊用 84-85度杀菌 一般 30-40分钟 PU值在1856左右
(取杀菌效率系数 Z=9℃) 过高的杀菌强度,会导致果汁变味,产生焦糊味,维生素流速等情况。
补充:实际生产中的复杂情况
若杀菌机是变温过程(如预热→升温→恒温→降温),需将整个过程按温度段拆分,计算每个温度段的PU值后累加求和,得到最终总PU(此过程通常由杀菌机的控制系统自动采集温度、时间数据并计算,无需人工手动拆分)。
• 低温巴氏杀菌(60-75℃):多用于对热敏感的鲜榨果汁(如橙汁、苹果汁),时间通常为 10-30分钟,以保留风味和营养。
• 中温巴氏杀菌(75-85℃):是工业生产中最常用的方式,时间缩短至 10-15分钟,平衡杀菌效果与产品品质(如市售瓶装果粒橙常用此范围)。
• 超高温瞬时杀菌(UHT,135-150℃):针对需长期常温保存的果汁,杀菌时间极短,仅 7-15秒,能最大化减少营养流失,且可实现无菌灌装。
The core calculation of PU (pasteurization Unit) is the cumulative value of "the killing effect of temperature on microorganisms × time", which needs to be combined with the sterilization efficiency coefficient at a specific temperature (Z value or L value, the Z value is commonly used in the industry), and it is specifically divided into two steps:
1. Clarify the core parameters
Two key values need to be determined before calculation:
• Reference temperature and reference time: By default, 60℃ is taken as the reference temperature. The sterilization effect in 1 minute is defined as 1PU (i.e., 60℃×1 minute =1PU).
• Z value: A coefficient that measures the impact of temperature on sterilization efficiency, referring to "the temperature increase required for a tenfold increase in sterilization efficiency". In the beer industry, Z=10℃ is usually taken (the Z value varies for different foods; for example, Z=8℃ for milk and 10℃ for beer due to its microbial characteristics).
2. Apply the calculation formula
If the temperature remains constant during the sterilization process (such as in the constant-temperature sterilization stage), the following formula can be directly used for calculation
PU = t × 10^[(T - 60)/Z]
The meanings of each symbol in the formula:
• PU: The total number of final pasteurized units;
• t: Actual sterilization time at temperature T (unit: minutes);
• T: Actual temperature during the sterilization process (unit: ℃, must be ≥60℃; the sterilization effect can be ignored when the temperature is below 60℃);
• Z: For the beer industry, take 10℃ (a fixed value, unless adjusted for special processes).
For example: Intuitively understand the calculation process
Suppose the beer is sterilized at a constant temperature of 70℃ for 5 minutes, calculate the PU value:
Substitute into the formula: T=70℃, t=5 minutes, Z=10℃;
2. Calculate the exponent part first: (70-60)/10 = 1,10 ^1 = 10;
3. Calculate the PU value again: 5 minutes × 10 = 50 PU
That is, the cumulative sterilization effect of "sterilization at 70℃ for 5 minutes" is equivalent to that of "sterilization at 60℃ for 50 minutes", ultimately resulting in 50 PU.
Supplementary: Complex situations in actual production
If the sterilizer is a variable temperature process (such as preheating → heating → constant temperature → cooling), the entire process needs to be split by temperature segments. The PU value of each temperature segment is calculated and then summed up to obtain the final total PU (this process is usually automatically collected and calculated by the sterilizer's control system, without the need for manual splitting).
