I feel blessed to live in one of the most beautiful areas in our country. The Pacific NW offers the perfect climate and landscape for summer recreation and one way to enjoy the great outdoors is to spend a Sunday afternoon driving through the hills and valleys of this region. A quick drive into the country can lead to beautiful landscapes covered with rolling vineyards and architecturally beautiful wineries. The wine industry has grown significantly in this area over the past several decades and in just an afternoon you can stop by more than a handful of destinations and sample a large variety of fine wines. On our last winery tour I was given yet another lesson on wine tasting, but this time the conversation was not about the actual wine itself. In fact, I spent nearly an hour with the vintner discussing wine bottle glass colors. You may be wondering how the color of the bottles could possible warrant that much attention, but in truth it plays a significant role in wine integrity and marketability.

Most wine connoisseurs know that proper storage conditions greatly affect the quality of wines. Light and high temperatures are the main culprits for altering wine integrity and can have a direct effect on taste and color. “Studies have shown that the color of the glass affects the color and aroma of the wine within when exposed to light; specifically it was found that green bottles have a greater protective effect against light than lighter colored bottles when held at a constant temperature. Interestingly, other studies have found the exact opposite, so it’s not completely clear what is going on inside those bottles when exposed to light.”1. Glass color measurement provides insight on how light affects wine after bottling and can help wine producers make important choices when it comes to bottling quality wines.

Using Spectrophotometry to Revolutionize Acrylic Paint Manufacturing and Labeling

Posted on Nov 29, 2023 by HunterLab

This week, I received a call from a manufacturing client who was struggling with a lack of customer satisfaction for one of their artist-quality acrylic paints. Apparently, the color on the bottles didn’t accurately reflect what the dried paint looked like by daylight, and the customers were demanding more precise labeling.

The problem, of course, is that this is an industry-wide issue.

In this case, I was able to help the client via a paradigm shift. By asking “what if?,” we came up with a solution that revolutionized their acrylic paint labels. I provided the client with the spectral analysis tools required to accomplish the task, and we journeyed into the artistic unknown.

Why Acrylic Paint Labeling Must Change

The problem with paint, of course, is that it dries. Most of the time, the dry shade differs (sometimes significantly) from the wet shade in the bottle, and differs yet again from the color swatch printed on the bottle label. Further complicating matters, the lighting under which the finished piece of art is displayed often renders the perceived color different yet again.

This presents a challenge when you are trying to advertise your product in color charts and catalogs (and, of course, in the bottle) and need to meet the high standards for artist-grade colors.

If labeling were to change, there is a largely open market to gain and the potential for a huge amount of brand loyalty. And if you’re a new manufacturer of acrylic paints and need to establish your reputation, a better label could set you apart. Spectrophotometry is the tool needed to break into this new market and enable a labeling revolution.

It’s Turkey Time: Using Visible Spectroscopy to Meet Consumer Demands for Poultry Inspection Safety

Posted on Nov 29, 2023 by HunterLab

November is finally here and you know what that means…turkey time! I am already digging through my cookbooks and planning our big meal for the end of the month, along with millions of other Americans. Turkey sale prices are cramming the local ads and poultry production lines are in hyperdrive this month. To keep up with the demand and ensure consumer safety, visible spectroscopy is now being used to differentiate between wholesome and unhealthy poultry products. With regard to such massive numbers, visible spectroscopy works more quickly and more accurately than the human eye can manage and provides the first step towards safety in high speed production.

Tea Fingerprinting: Combining Chromatography and Spectrophotometry for Quality Analysis

Posted on Nov 29, 2023 by HunterLab

After being a habitual coffee drinker for most of my life, I finally switched out my mid-morning cream and sugar-saturated cup for a healthier alternative: tea. Apparently I am joining the already millions of people who consume tea on a daily basis, making tea second only to water in popularity around the globe. Not only does tea come in a variety of choices, but high quality tea boasts numerous health benefits as well. Tea fingerprinting is the most widely used method for analyzing the quality of tea through chromatography and spectral analysis. Color, flavor, and health benefits are all related to quality, and new advancements in colorimetric technology offer better ways to measure these traits and provide quantifiable data through the use of spectrophotometers.

Spectral Analysis: Spectrophotometers Help Shine a Light on Meat Quality and Prices

Posted on Nov 29, 2023 by HunterLab

Friday night can’t arrive soon enough. With the reservation set at our favorite local steakhouse, my mouth is already watering at the thought of that flavorful and juicy cut of beef. Just thinking about it makes my taste buds happy, but what makes that restaurant steak taste so great? Superior establishments choose their beef based on quality ratings that are linked to tenderness and marbling, which is measured directly through spectral analysis. Spectrophotometers provide a spectral analysis of meat through reflectance values, which aids manufacturers in processing and packaging a product that meets consumer expectations, market price pressures, and standardized grading regulations.

Reflecting the price of quality

The dollar amount of meat depends entirely on the value of the cut, but both consumers and producers are often confused by what grading standards mean and how they are determined. These standards are developed by the USDA (United States Department of Agriculture) and are based solely on quality and composition. Spectral analysis is critical in determining categorization based on marbling (the amount and distribution of intramuscular fat) and reflectance value. Tender meat reflects more light than tougher cuts and can be measured using a spectrophotometer to determine light reflectance value. These measurements can then be used to help predict slice shear force values, creating more efficiency from processing to packaging.

Color Management: How Investing in Spectrophotometers Today Leads to a More Profitable Tomorrow

Posted on Nov 29, 2023 by HunterLab

When times are tough, cutting corners in color management may seem like the answer to saving those extra dollars, but unfortunately it usually has the opposite effect. Within the past decade, laying off employees  has been a reality for many, as well as pay cuts and salary freezes. As we climb out of this recession hole, we are left with limited resources and outdated technology. Color management and approval is often spread thin  between fewer employees and with new color product development and production growth, meeting production and quality standards becomes a real challenge. If we were to put ourselves under the spectrophotometer today, we may see the color of anxiety shining through as we scramble to meet the color management standards in a competitive global market.

Using Spectrophotometers to Develop Color Quality in Composite Deck Material

Posted on Nov 29, 2023 by HunterLab

Composite deck material is growing in popularity with improved color retention and durability, making the competition in this market grow. Image Source: Flickr’ Fiberon

Over 15 years ago, my husband and I installed a beautiful cedar deck. That first year it looked perfect; we painstakingly added several coats of stain to protect the surface and bring out the natural wood grains and colors. However, over the years this process had to be repeated again and again, with the tedious effort of removing old stain and sanding the surface clean to start fresh. Now, a decade and a half later, despite all our hard labor, the years have taken their toll and it is time for a replacement. These days, I am much more savvy on the costs of staining, stripping and sanding, not to mention the hours of time that maintenance of real wood consumes. So this time around we are strongly considering composite decking to reduce to labor and cost later on down the road..

Composite decking has come a long way over the past several decades. In the early days of production, color quality in composite deck material was limited and did not hold up well to the natural elements. Fading and degradation were often apparent, diminishing the popularity of these building materials. But despite these initial challenges, the sustainability of composite decking technology still held promise for the future and new industry competition quickly stepped up to the plate. These manufacturers found ways to improve the plastic composite material by using advanced instrumentation to monitor color and quality throughout the production process. Today, modern composite deck companies offer a variety of products with the look and feel of their real wood alternatives. As a result, sales of composite materials have skyrocketed, with last years sales topping the $1 billion mark1. With sales continuing to grow, manufactures are looking for new ways to improve the color stability and quality of their building materials in order to stay competitive in this expanding industry.
