Cricket flour is the misnomer term used to refer to powder made from crickets using various processes. Also known as hamen, cricket flour differs from true flours made from grains by being composed mainly of protein rather than starches and dietary fiber.
Products such as cricket flour are a sustainable and environmentally-friendly source of protein. Crickets grow and reproduce quickly with little maintenance required. Insect food production requirements are based on the 'feed conversion efficiency', this measures the amount of food needed to produce for an increase in weight. Insects, like crickets, require about 1.7 kg of feed to increase weight and it takes 3100 L of water to produce 1 kg of edible cricket protein. This is because crickets are cold blooded and rely on their environment to control metabolic processes rather than food. Insects are beneficial for the ecosystem. They release less greenhouse emission which is toxic for the environment. Insects are more edible. To date, one study has examined the water footprint, taking into account the entire production system, of commercially produced insects. This data showed insects are considered to be 80‐100% edible.Cricket flour#cite note-6|
Food Security and Processing
In Western countries, when raised for human consumption, insects are held to the same safety standards as any other food. The Food and Drug Administration, within the Federal Food, Drug, and Cosmetic Act, states that “The term 'food' means articles used for food or drink for man or other animals, chewing gum, and articles used for components of any such article.” Thus, with insects falling under said category, they must be safe and may not bear any added poisonous or added deleterious substance that is unsafe. Said items may not be prepared, packed, or held under insanitary conditions, and must be produced in accordance with Current Good Manufacturing Practice regulations for manufacturing/processing, packing, or holding human food. The FD&C Act also includes requirements that pertain to the labeling of food and preventive controls, as applicable. Manufacturers have a responsibility to ensure that the food they produce for the United States market is safe and complies with the FD&C Act and FDA’s implementing regulations. Processing can be done either commercially or locally depending on the popularity in a particular region. The process begins with removing the insides of the insect. Then, they are shipped to become preserved or freeze dried. This is done buy using hessian or polypropylene. After, they are completely preserved/dried they are shipped for storage. Insects can be refrigerated or processed into powders. Cricket flour is made with freeze dried crickets. Then, the crickets are baked to make the processing easier. After they are baked, they are ground into very fine pieces. The freezing, baking, and drying makes a dark brown powdery texture.
Cost
Prices will vary depending on location, but the average cost of pre-made cricket flour is around $40 per pound. The price is high due to limited commercializing and processors. Cricket flour is sold in limited areas, but mainly online and wholesale stores. The average prices for frozen crickets are about $9 per pound. These can be utilized in personally making cricket flour.
Food products with cricket flour
Pulverized freeze-dried crickets are used in processed food products, such as:
pasta
bread
cookies
snacks
smoothies
Cricket flour can be utilized as a complete replacement for flour. The taste is very nutty, and cooking quality may change.
Allergies
People with shellfish allergies may need to use caution when consuming cricket flour. Also, there is a risk of pathogens with consuming raw insects.
