Pineapple flavor and Allyl caproate

IMG_6799

My favorite unit in O-Chem(Organic Chemistry) was when the professor brought in a small bottle of Allyl caproate (aka Allyl hexanoate FEMA #2032) for the class to evaluate. It was my first exposure to a flavor aromatic. He passed around the bottle and asked us carefully smell the bottle and tell the class what we thought. I was intrigued, it smelled like pineapple. From that moment on, I was hooked on O-Chem. The unit's focus was probably naming or was focused on esters. Allyl caproate is an ester. Esters are often times described as fruity.  Allyl describes the group of atoms attached to the ester group.         Allyl caproate is fruity and smells like pineapple, but also has a … [Read more...]

Oil and Water; Math and Science

https://www.reference.com/science/don-t-oil-water-mix-5fa85ae059405d10

The orange peel contains the fragrance of the fruit, the "essential oil". An essential oil is different that a "fixed oil" (nut or vegetable oil) which is not fragrant. Flavor scientists value essential oils and they extract them so they can use them in flavors. These oils are excellent starting materials  for flavoring beverages, but they need to be modified to be useful. They do not "go into" a beverage. We modify the oils to make them "go in" or  make them "miscible". Chemists use miscible to explain the phenomenon of  two liquids with similar polarities (intermolecular interactions) being combined uniformly. In contract, chemists use soluble to explain the phenomenon of a solid (solute) dissolving in a liquid … [Read more...]

Lab Girl and Eucalyptol

LAB GIRL by Hope Jahren

Depression and anxiety are illnesses that haunt me. Sometimes they demand my undivided attention and other times they merely have an underlying presence in my thoughts. They hurt me, but they also help me develop new ideas. Hope Jahren's new novel, Lab Girl, chronicles her struggles with mental anguish as well as love of lab, science and hard work. In some ways, we are very much alike. We both: were born in 1969 love science and working in a lab are fascinated by nature understand Norwegian culture; having both lived there struggled as females in the science field with few women mentors like to write work too hard have difficulties managing stress and anxiety manage extreme anxiety by chewing hands or nails are … [Read more...]

Watermelon and 2,6-Dimethyl-5-heptenal (FEMA#2389)

Watermelon

Memorial day weekend is the unofficial start of summer and that means watermelon. Watermelon is the fruit we pack in the cooler for picnics at the park. In contrast, watermelon flavored candies are not a universal American favorite. Some people think only "monsters" like watermelon candy. When LifeSavers Five Flavors replaced the green lime flavored candy with a green watermelon flavored candy, it was a sad day. Like candy blog mentioned we were not asked what flavor we like; they just changed it. Personally, I find that watermelon flavor always seems to taste like cleaner or chemicals. Often, this is because a chemical found in watermelon and known to characterize it, 2,6-Dimethyl-5-heptenal (aka melonal) is too high (e.g. 0.1 ppm … [Read more...]

Vinegar and Acetic acid

Vinegar, cooking and cleaning type

"What's on the wall above the shower?"asks my husband. "That's mold", I say in unbelief, thinking "Is he completely unaware that mold has been growing on and off in our bathroom for at least a year?? Does he not notice anything??" He then asks nicely,"Did you know vinegar is good for cleaning mold?" I reply (almost sarcastically )"great, then can you get the vinegar, climb up there, and wipe it down?"  He tells me "I should probably do that", but I don't hold my breath. A few days later, I get the Lysol wipes, a step stool and rub the mold off the walls above the shower. I do not use vinegar but I do scrub.   Vinegar (~ 5% dilution of acetic acid) is a weak acid and a good sanitizer (kills germs). Mold is controlled by … [Read more...]

Grapes, Grandma and Methyl anthranillate

IMG_6299

My grandmother died last month. She's been in my thoughts quite a bit. In fact, just last week, while preparing grapes, I thought of her. Grandma showed me how to prepare grapes by cutting them into little bunches. She said little bunches are handy for grabbing, packing in lunches, and as snacks. Every summer, I spent at least two weeks at her beach house in Laguna playing in the ocean. After a few "wipe-outs" in the  waves, cold grapes were a good snack. This summer, while vacationing in southern California, I kept with tradition and prepared grape bunches for beach snacks. My kids loved the grapes as well as the ocean and boogie boarding. My last conversation with my grandmother was about my beach vacation and I told her my girls … [Read more...]

The Bitter Taste of Science Fair

Tonic Water (needed to make glowing slime)

I'm feeling drained this New Years. In fact, I blew off my resolution to join a gym so I could stay home and drink wine. I feel stressed because my kid wants to take part in the school science fair. From the moment I picked her up from school, I was overwhelmed. We returned from a vacation late the night before, so I had groceries to put away, dishes to clean, dinner to start, laundry to begin and a middle schooler who needed help with her math homework. My 3rd grader was now demanding I understand the  excitement of science fair? She insisted I arrange playdates to recreate experiments from you-tube and get her signed up for science fair NOW!  If that wasn't enough, she was adamant that we go to the store and get tonic water and potato … [Read more...]

Cheesecake flavor

last piece of amateur's cheesecake

I baked my first cheesecake Christmas day. The recipe seemed easy enough, but I got distracted and missed the instruction not to over mix. My family was forgiving and loved it none-the-less. In fact, they said it tasted better than the usual dense cheesecakes. Long story short, I am an amateur when it comes to baking cheesecakes, but I have plenty of experience making cheesecake flavors. Food companies that make yogurt, ice cream, white chocolate or baked goods often look for cheesecake flavors. In order to formulate a good cheesecake flavor, a blend of butter acids is important.  Some recommendations: Butyric acid (FEMA 2221)-a component of butter and cheese-smells like rotten milk iso Valeric acid (FEMA 3102)-a component of … [Read more...]

Buttered Popcorn

Homemade Popcorn

"Popcorn is such a great snack. It is easy to forget how easy and cheap it is to prepare at home." (Leanne Brown, Eat Well on $4 a day, Good and Cheap). Thanks to Leanne's encouragement and a $2 bag of popcorn, the Bautista family has been enjoying homemade buttered popcorn as a treat and snack. My eight year old may not care much about price or nutrition, but she is of the opinion that buttered popcorn "is fun" and screamed in delight when she pulled the lid off the popcorn pot too early.  My twelve year old also has an opinion, "I didn't think I liked popcorn until I tried homemade buttered popcorn", because "it tastes good. Can I have some more? LEAVE SOME FOR ME!!" There are aroma chemicals that smell like popcorn, but I have … [Read more...]

Apple Flavor and Ethyl-2-methyl butyrate

Lattin's Country Cider Mill & Farm, Olympia, WA

Americans love apples, hence the saying "As American as Apple pie". In Washington state, Apples are the largest agriculture crop with over 100 million 40 pound boxes being harvested annually. Last week I traveled to the "Apple Capital of the World", Wenatchee, WA. I was in meeting rooms most of the time, but I did manage to get out and purchase a big bag of Honeycrisp apples for home. My family never understood the fuss about Honeycrisp; until now. My children traditionally favor Gala or Fuji apples, but this bag of Honeycrisp apples opened our senses to what a truly a delicious apple Honeycrisp is. Next time, I will buy a crate of apples, because this bag only lasted a few days. These Honeycrisp apples were perfectly crisp, juicy, sweet, … [Read more...]
