Protaetia brevitarsis protein
- Different solutions were used to extract edible insect protein
- PH 1, 4, 7, 10, and 14 and 0, 0.1, 0.5, and 1 M NaCl
- PH of the extracted protein
- Increased with increasing pH (1.12±0.02 to 12.81±0.03)
- Decreasing NaCl concentration (6.52±0.02 to 6.89±0.01)
- Colour difference
- Increased when deviating from neutral pH and 0 M NaCl.
- Surface hydrophobicity (ug) and solubility (mg/ml) of the protein
- Decreased at pH 1 (12.25±1.39 ug and 0.74±0.08 mg/ml) and 14 (20.62±1.48 µg and 0.18±0.02 mg/ml)
- Compared with pH 7 (71.81±1.76 µg and 1.26±0.22 mg/ml)
- Higher pH and NaCl concentrations
- Yielded higher thermal stability
- Foaming capacity
- Highest at 0.5 (110.5±0.71%) and 1 M (100.5±10.61%) NaCl, and pH 14 (122.5±3.54%)
- Followed by that at pH 1 (72.50±3.54%), although with low stability
- Emulsifying capacity and stability of the protein
- Increased when deviating from pH 4.
- protein of P. brevitarsis
- Had high functionality when extracted at highly alkaline conditions using NaCl.

Tenebrio molitor (TM) and Pachymerus nucleorum (PN) oil
- Rats’ models
- Single oral administration (acute toxicity)
- 28 consecutive daily administrations (subacute toxicity)
- Considerable reduction in cholesterol and glucose levels of the treated rats
- Acute and subacute toxicology experiments suggested
- Did not cause any lethality
- no changes in hematological parameters.
- www.ocl-journal.org/articles/ocl/full_html/2022/01/ocl220011/ocl220011.html
- Could be considered as a therapeutic agent for the treatment of skin wounds
- Significantly increased the re-epithelization after skin injury (Kim et al., 2021)
- Positively affects the role of interactions among keratinocytes, fibroblasts and myofibroblasts.

Tenebrio molitor
- Growth cycle starting from 6.6% of lipid (fresh matter)
- For young larvae (mass around 23 mg)
- Increases to 11.7% for older larvae (154 mg size)
- Adult stage, the fat content decreases to 6.2% (fresh matter)
- Insect lipids mainly composed of triacylglycerols
- In minor amounts include
- cholesterol,
- Partial glycerides,
- Free fatty acids (FFA),
- Phospholipids
- Wax esters (Tzompa-Sosa and Fogliano, 2017)
- Most insect lipids are
- Liquid at room temperatures (20 °C) = “insect oils”
Tenebrio molitor crude oil
- Light-yellow oil of very good quality after a mechanical extraction
- Peroxide value
- First oxidation marker
- Very low 2–3 meq O2/kg
- Oleic acidity
- Marker of an aqueous or enzymatic degradation of oil
- Very low 0.25% oleic acid
- Liquid state is linked to the nature of the fatty acid profile
- Rich in unsaturated fatty acids
- Main fatty acid is oleic acid (C18:1omega9, 44%)
- Linoleic acid (C18:2omega6, 28%)
- Palmitic acid (C16:0, 18%)
- Very similar to
- Rice bran and peanut oils (Orsavova et al., 2015)
- Also of Acheta domesticus lipids

Cricket powder
- In Japan is added to elderly consumers’ food to improve digestion through a chitin-derived prebiotic.
- “Crickets require 10% of the feed needed to grow a kilo of beef.
- One kilo of crickets requires just 2.5 liters of water
- 8,000 times less than beef
- 15 times less than leading plant-based meats
Nam Dang, CEO of Cricket One.
- “Cricket production at scale is a feasible solution to feed the growing population and address SDG goals
- Cricket farm of 100 hectares
- Will be capable of producing enough protein for a country the size of Singapore
