Food Science in the News - Food Spoilage Red Light Green Light

Food waste is a major problem and expiration date confusion is one of the contributing factors. At a meeting of the American Chemical Society one scientist proposed smart-tags which could indicate whether food is spoiled. This innovation could alleviate some of the expiration date confusion and subsequent food waste. My only concern is that red means "fresh" and green means "spoiled".

When Granola Bars Roam Free

Perhaps it's because I'm a food scientist or perhaps it's because I have an odd sense of humor, but I always get a kick out of products labeled "natural." Let me share the 5 "natural" anomalies that amuse me the most.

The Linger - A Food Science Horror Story

I tried swishing with water and carbonated water, even alcohol when I got home; I tried brushing my teeth several times but it was still there.

This is a series of posts in which I share snippets of what it's like to be a food scientist. As a product developer for dry powder shakes, there are some lessons I never learned in school and some challenges I never saw coming.

Green-Eyed Insight on The Linger

It all started when we decided to screen different brands of stevia to improve Cost of Goods. Stevia is stevia is stevia, right? Oh, so wrong. One of those brands didn't seem as pure as the others and gave me a hint of a bitter metallic taste that just wouldn't go away. This is called The Linger, and it's a fairly common experience among food scientists and product developers. 

When I asked my colleagues if they'd ever had a taste that just wouldn't go away they all smiled and laughed with a look of nostalgia on their faces. Enduring The Linger is not a fun situation to find yourself in but eventually it does go away. The experience is a rite of passage, a badge of honor, like the first time you have to spend the night in your lab during Grad School.

Side note – if you ever have to spend the night in your lab during Grad School the key is to find three padded roller chairs and line them up so the seats make a soft elevated bed. Point the backs of the outer chairs in opposite directions as the chair in the middle so you can lie down atop the line of seats and have a makeshift wall on either side. If these padded chairs are on wheels (and they usually are) make sure the wheels are locked or that the outside chairs are pushed up against a desk or a wall. If you're taller than 5' 1.5", it might take more than 3 chairs, but the key is to alternate the directions the backs of the chairs are pointing. This alternate pattern keeps the chairs stable and keeps you from falling onto the floor. 

Eventually The Linger does go away but since it's not always caused by the same ingredient, the solution won't always be the same. A good tip to remember is "Like dissolves like" so in order of increasing hydrophobicity/decreasing water-solubility, try carbonated water, coffee, peppermint flavored gum or toothpaste, oyster crackers, peanut butter and olive oil. You may even find that alcohol works but please don't drink on the job unless your boss says it's okay. Until The Linger goes away, everything you put in your mouth will taste like the ingredient that caused The Linger. Don't panic and don't be tempted to over-eat to make the flavor go away. Rest assured it eventually goes away and you'll be able to tell the Newbie your Linger experience one day. 

Got your own Linger experience? Please share it.

I Ate the Whole Thing -- Food Label Hypothetical

Have you ever eaten a whole can of soup or a whole pint of ice cream? How about a whole bag of popcorn? These are just some of the products that are often consumed per container instead of per serving recommended on the label. But what if the label matched what we actually normally eat?

Secret Tips For Surviving a Convention, Expo and/or Conference

I used to work for a convention center as a cashier during all the big expos and conventions. Now I'm on the other side, walking the show floor and holding meetings throughout the day at several exhibitor booths. Regardless of the industry, there are ten "insider tips" I'd give to anyone who has the opportunity to attend an expo, conference or convention.

1--Bring a water bottle you can refill.

When I worked for the convention center, I used to tell my angry customers that the Convention Center water was magical, and that's why it was so expensive. That usually got a sympathy laugh, but bringing your own water bottle and refilling at the water fountains is definitely the way to go. I'd even add a lemon to the water bottle because some drinking fountain water doesn't taste that good.

2--Stay hydrated.

Attending a convention, conference or expo usually involves a jam-packed day of walking the floor and meeting people. Dehydration leads to fatigue, and sometimes grumpiness, not to mention the increased risk of binging on free samples (see tip number 3).

3--Go Easy on the free samples.

This tip is especially relevant to food industry expos like Natural Products Expo or IFT, but at any expo there are the people who get so excited by all the free pens, buttons and stress balls that they take home more branded junk than they need.  When it comes to food/beverage and supplement industry expos, it helps to remember that some samples are carefully monitored and frequently refreshed, and some samples are neglected and exposed for hours. In rare cases this neglect and exposure could lead to microbial growth or contamination. In most cases abandoned samples will just suffer sensory degradation, meaning they taste much less appealing than they do made fresh. As a food scientist, it makes me nervous when the Sales Rep wants to offer a sample tasting bar... ("Okay but pleaaaassee don't leave the tasting cups out for more than 30 minutes or my baby won't taste like it's supposed to!")

4--Bring plenty of business cards.

It's better to have a surplus of business cards and not need them than to miss the opportunity to connect with someone (or the opportunity to win a free iPad in those business card raffles I always see at expos).  Furthermore, with every business card you hand out you reduce your risk of having to throw away recycle those cards when you're promoted or change jobs.

5--Bring hand warmers.

Seriously, stopping at a sporting goods store and buying the camping pack of hand warmers may be the best expo/convention/conference investment I've ever made. Convention centers are always cold. Aside from the crankiness and drowsiness, the cold can lead to other uncomfortable conditions (see tip number 6).

6--Take an "Essentials Kit".

Cold air can lead to chapped hands and chapped lips, so bring a mini-bottle of lotion and some chap-stick. When you meet people for the first time at expos and conventions, you want to make a good first-impression and not be worried about a hangnail or whether or not your lunch is still in your teeth.  Bring floss and a toothbrush, a nail file or clippers, and a small packet of tissues. Ladies, you may want to bring a few other items...like bobby pins and makeup. If I had a nickle for every woman that's asked me for a rubber band or bobby pin when I worked at the convention center, I'd have enough money to buy Convention Center water.

7--Bring your own food (and caffeine!)

Food at these types of events is either free (see tip number 3) or expensive (see tip number 1). Since it's usually a jam-packed day, people don't have time to stand in line for 30 minutes for lunch. The alternative is to bring in your own food. Cuties, RTD protein shakes, baby carrots and pre-sliced apples with nuts or peanut butter are good snacks to bring along because they're small, mess-free and not temperature-dependent. With all the free samples it's probably not necessary to eat a whole 500 calorie lunch. As for the caffeine, well, it's not a necessity for everyone. Some people find caffeine helps if they have to work the booth or walk the floor all day. It also helps some people stay engaged and friendly/peppy when they've got meeting after meeting after meeting.

8--Don't look down on those with backpacks.

By the end of the day the free, branded, reusable bag you got at the door is straining with the weight and volume of all the flyers, free pens and samples you've amassed throughout the day. I know it looks silly, but a backpack is not something to scoff at. A backpack is actually a good idea if you have to bring a laptop for some of your convention presentations or meetings, a jacket for layering up in the cold, or a pair of comfy shoes (see tip number 9).  Of course there are some exceptions, and some backpacks that should be left at home...

9--Bring comfy shoes (and a pedometer).

Walking the floor is great exercise (but maybe not enough exercise to justify all the free samples you'll consume). You'd be surprised how many miles you walk during events like this so it's a good idea to wear a pedometer. The comfy shoes tip is one many people have already figured out. When I worked the convention center it was always fun to see how the footwear evolved from Day 1 of the expo through to the last day of the event. By the end, everyone is in flats so don't feel bad if you have to trade style for comfort. If anyone makes fun of your kicks, challenge them to a foot race.

10--Bring a cell phone charger.

Convention centers don't always get the best reception, and your smart phone may spend its battery power searching for a signal the whole day. Even if the signal was fantastic, battery power dwindles rapidly when you're using the expo app on your smart phone, taking pictures of booths or exhibits, or using GPS to find your way back to your hotel.

With these 10 tips, you can avoid common problems and pitfalls of the typical expo or convention. If you have any tips/tricks to add, I'd love to hear them. Thanks, and enjoy the show!

Reflecting and Looking Forward -- Big News for the Green-Eyed Guide

Perhaps it’s because my mind works in check lists and bullet points. Perhaps it’s because I’ve taken on a role that has dramatically improved my understanding of botanical ingredients and has strengthened my relationships with ingredient suppliers. Perhaps it’s because I sometimes make royal messes when I weigh out dry powder ingredients (see previous post – “The Xanthan Gum Disaster“). For whatever reason, I’ve been promoted from R&D Food Technologist to R&D Quality Assurance Specialist (see “What I Do When I’m Not Blogging“).

I see the projects I’m handed as a reflection of the confidence my team holds in my abilities, and thus the big expectations for me have filled me with excited determination. It reminds me of the first time my mom handed me the keys to the car and said “Okay, you can drive this time.”

I couldn’t be happier, but during this transition I’ve been incredibly busy. I apologize for not posting on a more regular basis but I intend to make up for that. Here’s what lies in store for the month of March:

Upcoming Posts for March on GreenEyedGuide.com:
