The Future of Food: How Analytical Techniques Are Changing Our Food

Burgers & BeerFrom veggie burgers that taste, smell, cook and look like real beef to transforming water into wine, the way we “grow” and make food and drink is changing—and analytical chemistry techniques are playing a major role.

“The future of food is synthetic,” Alec Lee, co-founder of Ava Winery, said in a recent interview with the Napa Valley Register. “Producing synthetic food is basically the next technology boom. Food tech is going crazy right now.”

Analytical Testing News Roundup: Turning Water into Wine & Craft Beer for Aquatic Conservation

Analytical Testing News Roundup IIAnalytical testing techniques are being used every day by scientists and researchers all over the world to make interesting and groundbreaking discoveries.

Below we roundup some of the most interesting and cool bits of news and research of analytical testing methods in action, many of which involve the making and perfection of adult libations:

1. Brewer & National Aquarium Partner to Create Craft Brew, Support Aquatic Conservation

A Delaware brewing company, Dogfish Head, has teamed up with the National Aquarium in Baltimore to create a brew that pays tribute to sea life, while also aiming to conserve it.

What’s the Difference between GC/MS and Ion Chromatography?

GC-MS vs. Ion ChromatographyAll manufacturers aim to create the highest quality and safest products for their customers. Often times, analytical testing services from a materials testing lab are enlisted to make sure manufacturers are doing just that.

Analytical testing can uncover the causes of product failures, identify contaminants or toxins, and also determine the chemical composition of samples. Two commonly used materials testing techniques are ion chromatography (IC) and gas chromatography-mass spectrometry (GC/MS). While both are forms of chromatography and can be used in similar ways, each is unique and valuable for different situations.

Below we discuss similarities and differences, and when each technique is utilized.

Why Cleanliness Testing is Essential for Medical Devices

While the actual construction and materials used in the medical device are essential to product quality, cleanliness is equally—if not more—important.

Cleanliness testing can ensure that your medical devices are free from contaminants that could lead to product failure, or pose safety risks to patients. In addition, the FDA requires that medical device manufacturers follow specific cleanliness validation procedures. Cleanliness testing can ensure that your products are meeting those FDA guidelines.

What is Cleanliness Testing?

Cleanliness testing aims to reveal any contaminants in, on, or outgassing from a product. Analytical tests such as liquid particle counting, outgassing testing, and ion chromatography are some of the most common types of cleanliness testing.

Evolving Microcontamination Testing Methods

Hard drives affected by microcontaminationHard drive manufacturers have been pushing the limits of technology since the medium of data storage was invented. It’s amazing that while storage capacity has increased exponentially, the size of the storage vessel has decreased significantly.  State of the art devices now store as much as 6 and 8 Terabytes (TB), and hard drives in the next decade could store as much as 60 TB. Technologically advanced hard drives like these require state of the art microcontamination and hard drive testing.

How Material Testing Supports Good Manufacturing Practices

In many industries, including biotechnology, pharmaceuticals, cosmetics and food and drink industries, complying with good manufacturing practices (GMP) to maintain government certification requires diligent material testing.

Good Manufacturing Practices (GMP) are a set of mandates set by regulatory bodies, including the FDA hyperlink and similar government organizations around the world, to ensure safety in products that are consumed and used in direct contact with people. A GMP badge on packaging, for example, implies that the regulatory agency has reviewed and approved the product’s manufacturing facility.

Are You Worried About Sulfites in Food?

sulfites in foodA bit of oil and vinegar in your salad makes for a simple, but delicious dressing. However, if you tend to get headaches often, that little bit of vinegar may trigger an aspirin craving.

Sulfites, the inclusive term for Sulfur Dioxide (SO2), are an allergy concern and are also hypothesized to trigger headaches. Because of this, governments regulate sulfites in food and drink products. The U.S. and Canada regulate the sulfite contents of wine, for example, at a maximum of 350 parts per million (ppm), and if it contains more than 10 ppm the label must note that the product ‘contains sulfites’.

What Type of Materials Testing Do You Need?

Materials testing for quality control

As a quality assurance specialist you are trained to spot quality issues and product defects. You know that if the fit isn’t right or the specified color mixture is slightly off, you can find the solution. However, quality control is difficult when there’s an unknown contaminant on your products or a mysterious product failure. In these cases, you might need to send a sample in for materials testing.

How IC Analysis Aids in the Production of Biofuels

IC analysis used to analyze ethanolMany Americans have started using ethanol fuel as an affordable and environmentally-friendly alternative to regular gasoline. The highly publicized E85 fuel is a blend of 85% ethanol and 15% gasoline and can only be used in specially designed vehicles known as “Flex-Fuel”. However, did you know that even if your car isn’t flex-fuel, you may be using ethanol? In fact, 95% of all automotive gasoline sold is blended with 10% ethanol, known as E10, and can be used by any normal gas powered car. Most states don’t require E10 manufacturers to label gasoline used with ethanol, so you may be pumping ethanol into your car without even realizing it!

7 Signs that it’s Time for Materials Testing

materials testing for clean production processesAs an engineering or manufacturing lead for your business, you have enough to do without trying to troubleshoot a mysterious product failure. From staffing issues to inventory and manufacturing to fulfillment, a product failure due to contamination or unexpected out gassing in transit is the last thing you want to hear about.

Luckily there materials testing techniques that can mitigate these risks ahead of time or quickly in the face of crisis so you can keep production moving.

Below are 7 issues that can be solved with the help of materials testing, and the specific testing methods to help you find the solution.
