Visions of Sugarplums
Sugarplums:
Not many people have had an actual sugarplum, but they don't only exist in book & song. A sugarplum was originally a candied plum; a way to preserve the taste of summer all year long. Somewhere along the way it became a mixture of dried fruits and nuts. And as far as Christmas candy goes, this is pretty healthy!
1 cup pitted dates (or figs)
1 cup toasted almonds
1 cup dried apricots
1/3 cup pistachios
1/3 cup candied ginger
2 tbsp grated orange zest (or lemon)
2-3 tbsp orange juice (or lemon)
Demerara sugar (or other large granular sugar)
Add everything except orange juice & sugar to a food processor & process until minced. Add juice until mixture sticks together. Form into 1" balls and roll in the sugar. Place in small, fluted cups or arrange on a platter.
This is just a basic recipe - feel free to get creative. You can add prunes, cherries, raisins, coconut, etc. Add what you like and what makes you happy. Next time you hear the Nutcracker Suite you really will have visions of sugarplums in your head!
Lollipops:
Lollipops are so simple, but they are interesting chemically. There is a finite amount of sugar you can dissolve in water, called a saturated solution (just over 200g sugar per 100g of water at 20°C). But as you increase the temperature of the water, you can increase the amount of sugar in solution forming a super-saturated solution. Unfortunately super-saturated solutions aren't very stable; the sugar wants to recrystallize. Since lollipops are amorphous, not crystalline, this is a problem. Luckily, it is one that isn't too hard to solve. For starters, wet down the sides of your pot to keep crystals from developing. These can become "seed crystals"; if they fall in the super-saturated solution they can cause the crystals to redevelop. We also add corn syrup (full of glucose & fructose molecules) to run interference with the sucrose molecules and break up their party. And lastly, don't stir the solution once it hits a boil; agitation is also something that causes the sucrose to recrystallize. We want clear, smooth lollipops not gritty, opaque ones.
1 cup sugar
1/3 cup light corn syrup
1/2 cup water
1/2 to 1 tsp Flavored Oil (cherry, cinnamon, peppermint, anise) of your choosing
Food coloring as desired
Candy thermometer
Paper or wooden lollipop sticks
Silpat or oiled baking sheet or oiled marble slab
Stir sugar, corn syrup, and water in a heavy saucepan. Bring to a boil stirring often and brushing down the sides of the pan with a wet pastry brush. Once boiling, cover and let boil 2-3 minutes. Uncover and put in candy thermometer, bring to 290°F. Remove from heat, add color & flavored oil; cool to 280°F. Spoon onto silpat or oiled surface (or into molds). Add sticks while still hot & pliable; spoon a small amount of candy over the stick to help hold it in place. Let cool completely.
I hope you are inspired to try one (or both!) of these recipes and that you've learned something new. I've had fun with all of this sweet talk but I promise to move on from sugar in the next post, before we all get cavities from the sugar overload!

Sugar Sugar
Well my sweets, before I go into a sugar crash, I think it is time to close this post. I'll stay on saccharides next post, but will talk about some of its other forms. Bye!

C is for Carbohydrate
The role of carbohydrates in human nutrition is to supply a readily accessible and quickly utilizable form of energy. They allow your body to spare its muscles (protein) from being broken down to supply the needed fuel. We may be complex creatures, but we run on the simplest of sugars, glucose. In fact, it is the only fuel our nervous systems and brain can use.
So let's start our foray into this topic with the simplest of the carbs - sugars. Sugars come in multiple forms: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. As you can tell from the prefixes, they are made of sugar molecules ranging from one (mono) to many thousands (poly). Sugars also have the suffix '-ose', which designates them as being part of the sugar family. {For those of you who are chemistry junkies, this is the site for you.}
Monosaccharides are single sugar molecules, as I've mentioned, and the most important of these is glucose (also called dextrose). It has the chemical structure [C6(H2O)6] and exists in a ring (cyclic) formation. But there are other monosaccharides besides glucose such as fructose, xylose, galactose, and ribose.
Disaccharides are, as their name suggests, sugars comprised of two monosaccharides. They occur when the two monosaccharides join together and kick out a water (H2O) molecule in a dehydration reaction forming a glycosidic bond. Different combinations of monosaccharides come together to form different disaccharides. Glucose + Fructose = Sucrose (what we call table sugar), Glucose + Galactose = Lactose (milk sugar), and Glucose + Glucose = Maltose (malt sugar).
Oligosaccharides are sugars comprised of 4 to 8 monosaccharides (oligo means few) and are known as simple sugars. The most common are fructo-oligosaccharides which occur in vegetables (like asparagus & onions) and are short chains of fructose molecules. They are of particular interest these days because of research that proves they enhance the growth of beneficial gut bacteria - this is called a prebiotic effect. Because of this, food scientists are finding new applications where they can add oligosaccharides.
And lastly, polysaccharides are long chains (100+) of monosaccharides. Typically they are insoluble in water and are not sweet. You know some of them as starches and cellulose. There is also one which you may not be as familiar with (yet) called inulin. And like a fructo-oligosaccharide, has a prebiotic effect that aids in digestive health. Inulin belongs to a category of carbs called fructans. {For more information on inulin: click here}
So to recap - carbohydrates are the fuel our bodies run on. Sugars are the simplest forms and as you add on molecules, they become strings and those strings become chains, which makes them less soluble and less sweet. In the next post I will continue to discuss this category of carbohydrates and some of their individual details. Until next time - Stay sweet!

What's My Function?

A Perfect Score
Bioavailability - the degree to which a substance can be digested and utilized by the body in the amount and form in which it is present.
% Biological Value (% BV) - the proportion of absorbed protein (Nitrogen balance) that is retained in the body for maintenance and/or growth.
Casein (milk protein) = 85% Whey Protein Isolate = 98% Soy Protein Isolate = 80%
Rice Protein = 64% Whey Protein Concentrate = 95% Whole Egg = 100%
Net Protein Utilization (NPU) - the proportion of protein intake that is retained; a completely digested protein would have an equal %BV and NPU value.
Casein = 76 Whey Protein Isolate = 92 Soy Protein Isolate = 61
Rice Protein = NA Whey Protein Concentrate = 93 Whole Egg = 94
Protein Efficiency Ratio (PER) - based on the weight gain of a growing test animal (rat) divided by its protein intake over a study period (usually 10 days).
Casein = 2.9 Whey Protein Isolate = 3.5 Soy Protein Isolate = 2.1
Rice Protein = 1.3 Whey Protein Concentrate = 3.0 Whole Egg = 3.8
Protein Digestibility Corrected Amino Acid Score (PDCAAS) - a method of comparing protein quality based on the amino acid requirements of humans (a score of 1.0 = a complete protein, i.e. 100% of the essential amino acids after digestion).
Casein = 1.23 Whey Protein Isolate = 1.14 Soy Protein Isolate = 0.92
Rice Protein = 0.55 Whey Protein Concentrate = 1.0 Whole Egg = 1.19
So, does anyone really pay attention to these values? A few do, (body builders, olympic atheletes) but most of us don't. Does this have any practical applications? Can you use this info? Well sure. If you happen to like protein bars, you can use this information when looking at the nutrition panel to determine the quality of the proteins it contains. If you are a vegetarian/vegan, you can use this information to make sure you are getting a complete compliment of proteins in each meal so your body doesn't feed on itself. And you can impress people at the gym with your newly acquired expertise on this topic! Ok, maybe that's just me.
So, what's next you ask? Well, you know what a protein is and you know how to judge their quality, so how about what it is they do in the food products you purchase? In my line of work we are far more concerned with the properties different proteins exhibit and I will tell you all about it in my next post.

A Protein Primer

Where to Start
Food (fōōd) n. 1. A substance, usually of plant or animal origin, taken in and assimilated by an organism to maintain life and growth: nourishment. That's how Webster's Dictionary defines it, but it isn't the legal definition our industry uses. We use the definition from the Federal Food, Drug & Cosmetic Act which defines food as: (1) Articles used for food or drink for man or other animals, (2) Chewing gum, and (3) Articles used for components of any such article (i.e. ingredients).
But what is food really? Essentially it is all of those items you find on a label and nutritional data panel. It is comprised of three main constituents: protein, fat & carbohydrates. Lets start here; there is plenty of time to cover the other organic & inorganic substances found in what we eat. I want you to understand the basics.

Welcome to Food Literate
I can't really remember a time when I wasn't in the food industry. You see, I am the third generation of my family to work with food. I grew up, literally, in a food manufacturing plant, but that's not my only credential. I hold a Bachelor of Science in Food Technology from The Ohio State University and have almost 20 years of experience in the field.
I spent the first half of my career on the product development bench designing new marinades, glazes, coatings, snack seasonings, soups, gravies, and side dishes. I've served as a trained sensory panelist, written FDA and USDA formatted labels, and performed application work with flavors.
I've spent the second half of my career as a laboratory director involved in technical and regulatory services. I am immersed in the constantly changing world of FDA regulations, DOT regulations, The Bioterrorism Act of 2002, kosher & halal certifications, GMO, BSE, BST, irradiation, MSDS, etc. I am a Certified Food Defense Coordinator and am in charge of Food Security at the company for whom I work.
I have completed my culinary coursework at the esteemed Culinary Institute of America (CIA) so that I can become a Certified Culinary Scientist (still need to take my test). I am a Professional Member of the Institute of Food Technologists, a Food Science & Technology Member of the Research Chefs Association, and a Member of the Women's Foodservice Forum, where I am active in Committee leadership.
In a nutshell, I'm a food geek. So much so that my friends and family encouraged me to share some of this knowledge of food, ingredients, their workings, and this industry with you and anyone else that happens to land on my little corner of the internet.
Why this site:
To expose and refute the junk science and unsound information you see and read daily on television and on the internet spread by purported pundits, unscrupulous marketers, shady advocacy organizations, and uninformed journalists. It is also to share information about the ingredients and processes used to make the foods we all love. Our society is very far removed from its food. It comes in brightly colored, fantastically marketed packaging but too few consumers know how it actually gets from the farm to the family dinner table.
Let's face it - we are a nation of food illiterates.
There are too few people that actually have basic food knowledge and they tend to get their scientific information concerning the food they eat from Alton Brown (whom I admit, I do adore). I'm pretty sure I may be on to something simply because not a day goes by that someone doesn't ask me a food-related question (outside of my work responsibilities).
This website is dedicated to fielding questions, having conversations, and disseminating food-related information to a wider audience. I will endeavor to keep the information interesting, fun, and useful. I'll trust that you'll let me know how I'm doing!
