概括
电子商务的乳制品配送显示了可变的温度配置,对液体牛奶的保质期的影响最小. 需要进一步的研究来评估这些易腐的商品的感官质量和消费者接受度.
科学领域:
- 食品科学 食品科学 食品科学
- 供应链管理 供应链管理
- 微生物学 微生物学
背景情况:
- 电子商务食品分发,由COVID-19大流行加速,已经扩大到包括更广泛的易腐烂产品和更长的运输距离.
- 越来越多的杂货电子商务引入了潜在的温度滥用,冒着像乳制品等易腐烂物品的腐烂和质量下降的风险.
- 了解各种电子商务分销道对乳制品保质期的影响,对于保持质量和安全至关重要.
研究的目的:
- 评估电子商务分销对流体牛奶和希腊酸奶保质期的影响.
- 在不同的电子商务运输路径中分析时间-温度概况.
- 评估模拟电子商务条件下的乳制品的微生物和感官保质期.
主要方法:
- 监控流体牛奶和希腊酸奶的模拟和真实电子商务时间温度概况,通过三个道进行监控:直接向消费者,企业向消费者和企业向企业向消费者.
- 对流体牛奶进行了微生物和感官保质期测试,使用从1.89升牛奶运输中测量的温度配置.
- 利用计算模型根据温度数据和初始细菌度预测牛奶腐烂.
主要成果:
- 产品交付温度在道之间有很大的差异,从 -0.9°C到19.2°C.
- 企业到企业到消费者交付的牛奶和酸奶的平均到达温度分别为7.2°C和7.3°C.
- 从电子商务条件中模拟的短期温度暴露对流体牛奶的微生物和感官保质期产生了有限的影响,得到了预测模型的支持.
结论:
- 乳制品的电子商务分销表现出相当大的温度变化,突出了潜在的冷链挑战.
- 目前的电子商务条件似乎对流体牛奶在保质期结束时的微生物破坏的影响很小.
- 未来的研究应该专注于评估感官质量和消费者接受度,因为当前的模型预测微生物生长,而不是感官属性,这显著影响消费者选择.

Factors Influencing Microbial Growth: Temperature
1.1K
Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...

Physical Methods for Controlling Microbial Growth: Temperature
955
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

Effects of Temperature on Free Energy
27.9K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Responses to Heat and Cold Stress
14.7K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
