揚げ物調理に使用して劣化した食用油の廃油時期(酸価値2.5～3.0)の目安を判断する為の試験紙です。 調理後のまだ熱い油に先端を浸けるだけなので、簡単に使えます。 油の捨て時がわかりやすい!紙が紫から緑に替わると捨て時です。 簡単にわかりやすいのでアルバイトの方や新人さんでも判断できます。 厚生労働省の「弁当及びそうざいの衛生規範について」(環食第161号、昭和54年)の通知では、「揚げ調理中の油脂が発煙点170℃未満、酸価値2.5超、カルボニル値50超で明らかに劣化していたら、そのすべてを新しい油脂と交換すること」としています。

酸価測定の公定法である酸・アルカリ滴定法の原理に基づいてpH指示薬、塩基性物質を濾紙に含浸し、乾燥させた試験紙です。 フライ油(加熱油脂)など、現場の品質管理に適しています。 判定時間(測定所要時間)は極めて短く、約30秒となっています。 判定操作はごく簡単で、誰にでも判定を行うことができます。 従来の酸価測定キットと異なり、溶剤を使用していないため、火気を特に意識することなく使用することができ、また、使用済みの試験紙は償却が可能です。

Description。USB-C is fantastic. What makes this cable even better is that one of the features we love so much about USB-C has been replicated to the USB-A 2.0 plug! These cables have minor， yet genius modifications that allow them to be plugged into their ports regardless of orientation. No longer will you fight the USB "super position" where both orientations of your plug seem incorrect. A simple solution to a problem that nearly everyone has faced.。Until we have converted all our hubs， chargers， and ports over to USB-C this is the cable you're going to need for basic USB 2.0 connections. This cable is much thinner and flexible than its 3.1 counterpart and is perfect for USB to serial applications as well as for direct connection to basic microcontrollers.。This cable has the D+/D- wires along side large-gauge VBUS/GND wires.

Description。The SparkFun Qwiic micro：bit Breakout is a board that connects to the BBC micro：bit and expands the capabilities of the development platform by providing access to more pins and allowing for connections to the I2C and SPI buses. This breakout board for the micro：bit's edge connector allows intermediate and advanced users to connect the micro：bit to breadboards and other Qwiic sensors， motors， LEDs and more.。The micro：bit on its own has three digital/analog input/output rings available for you to use initially with alligator clips. With the micro：bit Breakout we have broken out all 21 GPIO， power and ground-to-pin outs in a 0.1" formation and with two individual Qwiic Connectors. With this breakout you will be able to unlock the full potential of your micro：bit!。Note：。No micro：bit or headers are included with this breakout； they will need to be purchased separately. If you would like a micro：bit breakout with headers already soldered on， be sure to check out this board's sibling.。The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.。Get Started with the Qwiic micro：bit Breakout Guide
