——水活度能揭示面粉的什么特性？

你能通過只是簡單測試碾磨處理過程中的面粉的水分活度，來看出來面粉的不同之處么？

過去的幾個月里，Decagon食品實驗室一直在研究不同調和技術所處理的面粉，看看是否可以檢測出面粉在碾磨之前是否被妥善的處理了。

他們同時也研究了柔軟的和堅硬的面粉，顆粒大小不同的面粉以及不同調和技術下的面粉之間的吸附性能的差別。

其結果對于那些與谷物加工產品打交道的人和對通過檢測水活度來評估原材料質量有興趣的人們將是非常有趣的。

 October Virtual Seminar:
What a_w Reveals About Flour

Can you detect differences in the way flour was handled during the milling process simply by measuring its water activity? 

Over the last several months, the Decagon food lab has been looking at flours (white and farina) made with different tempering techniques to see if you can l whether the flour was handled properly prior to milling.

They’ve also been looking at differences in sorption properties between hard and soft flours, flours of different particle sizes, and flours treated differently during tempering. 

The results will be interesting to anyone who works with grain-based products—and to anyone interested in using water activity to assess the quality of raw ingredients.

November Virtual Seminar: 
Tree Nuts

There's a moisture sweet spot in almonds, pistachios, pecans, walnuts. Too wet and they mold, too dry and they break in the bag. 

Historically, the industry has used moisture content to make this measurement, but many manufactures have no faith in the moisture numbers. You can have in-spec product that molds in storage. 

The Decagon food lab has some recent findings to share on this topic, including:

? How you can establish a moisture specification that prevents mold and reduces breakage

? How to improve the consistency and reliability of moisture content measurements

? Whether or not you can see an inflection point in the isotherm of a tree nut

? A survey of the water activity of commercially available nut products
