Black Soldier Fly Larvae – Tasting Notes

Black Soldier Fly Larvae are a leading insect for feed applications. If you have ever seen a chicken eat BSFL, you will know why, the love it! No one seems to be targeting the use of BSFL for food. Let’s answer the question on what they taste like.

EnviroFlight kindly provided samples for evaluation. Please note that their production system is designed for feed applications and not food.

Black Soldier Fly Larvae – Dried, Wholeimg_0009

Aroma – pungent, strong earthy, fishy. In my opinion, the aroma is not very appetizing. In some respects, similar to dry roasted cricket powder. BSLF is fishy vs shrimp-like and is stronger.

Flavor – earthy, chocolate-like, malty, the fish flavor perception is very low, mildly sweet. The taste is a lot better than the aroma.

Texture – the dried whole BSFL have a very soft texture. They mostly dissolve upon chewing. The texture was not chalky.

Black Soldier Fly Larvae – Oil, Crude

The flavor had more pronounced chocolate/malty flavors. The fat was solid at room temperature. When warmed slightly to melt, the color is slightly yellow.

Defatted, milled Black Soldier Fly Meal (much of the fat is removed by mechanic press prior to milling)img_0011

Aroma and flavor was similar to the dried whole BSFL. The dried whole tasted slightly better as the fat portion was not removed. The texture was not chalky.

The powder did not dissolve well in water.

Can BSFL be used as a food ingredient?

The strong aroma and flavor pose challenges for using BSFL as a food ingredient. The preferred culinary use would be to cook fresh (not dried) BSFL. The flavor of fresh is likely a lot milder and more palatable. Businesses harvesting BSFL are also focused on feed applications but that could change.

There are techniques to reduce flavor that can be applied to dried product. Solvent extraction using ethanol or hexane should work. Another is super-critical carbon dioxide extraction. It would be interesting to try these on cricket powder too.

Grasshopper Wild Harvesting Using a Net

Grasshoppers are commonly consumed in Mexico and regions of Africa. However, they are hard to come by in the States. (Unless, you live next to some tall grass and its the right season. Being in Texas, there are plenty of grasshoppers to go around.)

Lets get right to the interesting stuff… what did I catch and what did it taste like!

5 different grasshopper species.

Preparation: The insects were frozen then rinsed. They were cooked in butter/oil until they changed color and held for an additional 2 minutes.

After cooking:

Flavor

The flavors were very mild. They have a brothy flavor that is sort of like vegetable broth but non-descript. They didn’t taste like any particular protein or vegetable. The closest flavor I can think of is seaweed with a little bit of asparagus. I tried just 3 of the varieties and they were all similar in flavor.

The textures were pleasant. The exoskeletons broke down upon mastication. They were pretty dry; not a meaty texture.

How and where the insects were harvested:
Choice of Net

There are two main types of nets used by entomologists (Texas A&M video on nets). The aerial net and the sweep net… I choose the somewhat DIY way. I picked up a heavy duty leaf rake for pool cleaning and the local department store. The big advantage, it turns out, was the 8 foot pole!

insect grasshopper net pool entomophagy

It worked well as is. Once a grasshopper was in the net I just grabbed it and put it into the jar. I could only catch one at a time this way. Im thinking about cutting open the bottom of the net and adding netting from a mesh laundry bag. It would make it more difficult for them to jump back out (yes, this happened a few times).

Location

From Phone 296

I found a nice patch of uncultivated lane ‘behind a gas station’. The grass varied in density, type and height. The best spots were where the grass was dense and near a ravine. I knew I found a good spot because they were pretty loud.

Season

I set out in the early afternoon on a hot Texas day in August.  I probably should have waited until the evening as they are less active when the temperature drops. My understanding is that they are less active in cooler temperatures. The large ones can fly up to 20 feet making them really difficult to catch.

Food Safety – Message to Consumers

Food safety is a key concern when consumers make food choices. Most westerners are unfamiliar with how insects are used as food which casts doubt on their safety. Here are some key points of discussion.

  1. Insects are harvested and processed just like any other food.
    •  The insects are harvested specifically for human consumption
    • They are free from filth and extraneous material.
    • They are handled and processed using Good Manufacturing Practices (GMPs) and in compliance with food laws.
  2. People have been consuming insects as food for thousands of years.
    • Insects have been an important part of our evolutionary diet.
    • Today, insects provide necessary protein in some native diets.
    • In certain places, insects are considered a delicacy.
  3. Over 2 billion people consume insects on a regular basis.

Some other thoughts…

Not all insects being consumed are farm raised. Imported products and even domestic insects are sometimes wild harvested. So a blanket statement saying that the insects we are distributing/promoting are all farm raised would not be accurate. Imported products are also more difficult to audit due to geographical and language barriers. Id love to hear more thoughts on how insects are being demonstrated to be wholesome and what documentation is available to support that.

Cricket Powder Tasting Notes

Akketa and Cricket Flours were fresh samples and had the most flavor. The flavor and aroma were characteristic of cricket flour. Crustacean/shrimp-like, nutty, beany. All Things Bugs cricket powder was distinct having a mild flavor that was somewhat malty. The sample I have from World Ento is about a year and a half old and was mild in flavor; the flavor profile is characteristic and no other defects.

Samples of cricket powder were evaluated strait up and in water.

Production Costs for 1 Bottle Of Cricket Worcestershire

Ive broken down the production cost into 3 parts – Food Ingredients, Packaging Costs and Overhead.

I have not executed yet so I might be off on my estimates. The overhead cost is modeled on producing 200 bottles using a commercial kitchen. Im overestimating the time is will take to produce 200 bottles which is really driving up the cost.

Packaging $ Per Bottle
Packaging – bottle 0.33
Packaging – cap/reducer/wrap 0.13
Packaging – label 0.25
Total Packaging Cost 0.71
Food Costs $/lb Usage Extended cost $/lb
Worcestershire Ingredients 2.00 50.0% 1.00
Cricket Broth 1.80 50.0% 0.90
Cricket Worcestershire 1.90
95% Yield 2.00
Labor/Overhead Staff # $/hr bottles/hr $/bottle
Facility Rental 100.00
Labor 2 30.00
Through put 50
Total Overhead Cost 2.60
Total Costs $/Per bottle (5 oz)
Cricket Worcestershire 0.63
Packaging Cost 0.71
Labor/overhead 2.60
Production cost per bottle 3.94

There are a few other costs that need to be taken account for. Im concerned with distribution costs. Who will fulfill orders via direct online sale and how much will it cost to do so?

Beyond Cricket Flour

Cricket flour does have its virtues. Its shelf stable, easy to use and takes away the ick factor. But like any other food we eat, there are tons of different types of insects and and even more ways to prepare them.

The next step beyond cricket flour is frozen whole crickets. This will provide consumers with a bigger and blanker canvass for there culinary creations.

I have always thought canned crickets is a great ideaPhoto Aug 22, 11 22 16 PM.

The best cricket dish Ive had so far has been ‘popcorn crickets’. Lightly battered and deep fried, they had a crispy exoskeleton and mouth watering aroma similar to shrimp. This concept could be sold in the frozen food section of the grocery store next to chicken nuggets. And also distributed through food service for places like carnivals or other street food.

One of the more interesting concepts I have heard of is a fermented cricket sauce that is produced in a manner similar to fish sauce. The possibilities are endless.

What other insects are out there… Wax worms!

Wax worms taste really good. Re-fried beans traditionally use lard but wax worms work great instead. They have the same sort of fatty flavor to them.

Another insect is agave worms. In Sal De Gusano, roasted agave worms are used for their smokey flavor and savory taste. Use insects for their flavor as well as a source of nutrients.Photo Dec 06, 4 26 27 PM
