Do you think the magnetic tongue is useful? Why or why not? - Yes‚ because the magnetic tongue is as good as a professional food taster when it comes to assessing flavours. 3. What is NMR spectroscopy? - It is an analytic tool that allows scientists to study the physical‚ biological‚ and chemical properties of matter. p. 19 1. What

This is done using liquid/solid extraction and chromatography. Once the Lycopene is isolated‚ IR spectroscopy will determine its percentage actually obtained by chromatography. Procedure: A massed sample of 1.012g of tomato paste was placed in a 125mL Erlenmeyer flask. To the flask‚ 5mL of 50:50 hexane-acetone was added into the flask. After the

Rubidium forms amalgams with mercury and alloys with gold‚ sodium‚ potassium‚ and cesium. Rubidium glows red-violet in a flame test. Rubidium Trivia: • Rubidium melts just a little above body temperature. • Rubidium was discovered using spectroscopy. When Bunsen and Kirchoff examined their sample of petalite‚ they found two red spectral lines deep into the red part of the spectrum. They named their new element rubidium after the Latin word rubidus meaning ’deepest red’. • Rubidium is the

Ocimum basilicum‚ commonly known as ‘Indian basil’‚ is an indigenous south Indian species (Bhasin‚ 2012). Among over 150 basil species belonging to the genus Ocimum‚ two most widely grown species for essential oil production are holy basil (Ocimum sanctum L.) and sweet basil (Ocimum basilicum L.). Ocimum basilicum‚ an erect highly branched aromatic perennial herb of family Lamiaceae is well known for its sweet basil oil and is widely distributed throughout India. This species is believed to be originated
