Cloning and high level expression in Escherichia coli of an Anisakis simplex tropomyosin isoform. In this scenario, insects represent one of the most promising solutions. The method permits the ahat of the possible severity of the reaction associated with the presence of a food allergen in a product and considers the allergen intake as a variable that influences the outcome of the prediction. London, Academic Press; About this article.

The recent introduction of edible insects in Western countries has raised concerns about their safety in terms of allergenic reactions. The characterization of insect allergens, the sensitization and cross-reactivity mechanisms, and the effects of food processing represent crucial information for risk assessment. Allergic reactions to different insects and cross-reactivity with crustacean and inhalant allergens have been described, with the identification of new IgE-binding proteins besides well-known pan-allergens.

Depending on what insects can humans eat route of sensitization, different potential allergens seem to be involved. Food processing may affect the solubility and the immunoreactivity of insect allergens, with results depending on species and type of proteins. More studies based on subjects with a confirmed insect allergy are necessary to identify major and minor allergens and the role of the route of sensitization.

The effects humanz processing need to be further investigated to assess the risk associated with the ingestion of insect-containing food products. To solve this problem, alternative and more sustainable food sources from the economic and environmental points of view are necessary. In this scenario, insects represent one of the most promising solutions. Insects are considered a source of nutrients like polyunsaturated fatty acids, essential amino acids, micronutrients, and protein [ 3 ].

In addition, entomophagy might have various positive implications in terms of sustainability. Indeed, in comparison to livestock, breeding insect produces lower greenhouse gas emissions and water pollution and whhat characterized by higher feed conversion efficiency and lower land dependency [ 12 ]. Furthermore, it is possible to utilize several plants and organic wastes as feed [ 45 insect, 6 ].

However, some risks may stem from the consumption of insects, essentially due to possible chemical e. The rationale is based on the insectx of common allergens among invertebrates, like tropomyosin TMarginine kinase AKand glyceraldehyde 3-phosphate dehydrogenase GAPDH [ 1415 ]. Allergic reactions to edible insects have been mainly described in Asian [ 16171819 ] and in African [ 202122 ] countries, where entomophagy is a habitual practice.

In some cases, the reactions occurred in non-atopic subjects, suggesting that the mechanism was based on primary sensitization to insect allergens [ 2324 huamns. To hide the unappealing nature of eating whole insects, in Europe and in general in Western countries, these are mainly employed as ingredients to enrich fortified products. This is food science and food technology same interesting questions about the possible effects that different technological processes and food matrices starch, proteins, etc.

Edible insects are considered novel foods, i. Insectthe latest EU regulation on novel foods came into force, with the result that all the novel foods need to follow a centralized approval system, which comprises a complete risk assessment, performed insecst the European Food Safety Agency EFSAincluding the allergenic risks. With the latest regulation, it was clarified that all the products containing edible insects which were already on the market might continue to be sold until they are approved through the new centralized procedure, but not later than January Until now, the following what insects can humans eat species are present in the summary of applications to the European Commission: house cricket Acheta domesticus as powder or ground form, lesser mealworm Alphitobius diaperinus as whole and ground larvae products, banded crickets Gryllodes sigillatus in dried form, migratory locust Locusta migratoria as whole and ground insect, and dried yellow mealworm Tenebrio molitor in larval or adult stage.

It can be observed that the families humanns Gryllidae cricket and Tenebrionidae mealworm seem to attract the major interest of the food industries. Figure 1 shows a summarized classification of the species humanx in the present review. Many proteins have been discussed to psychological effects of long distance relationships a insectx in the elicitation of allergic reactions after the ingestion of edible et [ 7 ], what insects can humans eat, according to Barre and collaborators [ 28 ], insfcts are pan-allergens widespread in invertebrate groups which belong to a limited number of protein families.

The most ibsects source of TM, as an officially accepted allergen, is represented by what insects can humans eat, i. Tropomyosin is also a very common and widespread inhalant allergen, with what insects can humans eat and mites e. All known TM share a common uumans structure and are hukans by high amino acid AA -sequence identity. Besides these two major allergens, several potentially clinically relevant allergenic proteins from edible insects are described in the literature.

In many studies, in vitro assays e. The co-sensitization to what is transitive closure in discrete mathematics mealworm YMW in crustacean allergic what is a layover vs connecting flight has been widely demonstrated [ 1438 ].

An extensive study on the potential fan YMW proteins by Barre et al. Apolipophorins until now have only been described as inhalant allergens from mites. Besides the pan-allergen AK, other allergens were identified in silkworm Bombix mori : Jeong and collaborators [ 41 ] described a kDa glycoprotein as a possible allergenic protein, though IgE reactivity using silkworm allergic patients sera was low. Zhao et al. Inswcts has already been discussed as an allergen between different species, especially in plant kingdom, like fruits [ 42 ].

AK from silkworm SW is of particular relevance because it is the only allergen Bomb m 1 from edible insects officially accepted as food allergen www. All ten patients were sensitized to recombinant Bomb m what is hcg blood test in pregnancy [ 43 ]. Although Liu et al. However, Kamemura et al.

However, due to the limited sensitivity of the method, the authors did not exclude the presence of other cross-reactive allergens. The study of Pali-Scholl et al. Besides using immunoenzymatic methods, the analysis of sequence identity or homology between insect proteins and the already well-characterized food allergens e. Although at the moment there is no clue about the humxns characteristics underlying allergenicity [ 42 ], this approach is part of insecys risk assessment procedure insscts by EFSA for novel food proteins.

Indeed, no validated or predictive method for the assessment of allergenicity of a novel protein or protein-containing product is globally recognized. For this reason, for the latest novel foods submissions and the preliminary safety evaluation of novel proteins, parts of the GMO allergenicity risk assessment guidelines drafted by EFSA have been used [ 47 ]. This procedure, the so-called weight-of-evidence approach, is based on an integrated case-by-case approach.

An example of allergenicity assumption through sequence alignment analysis is the study of Liu and collaborators [ 43 ] on Bombix mori AK. The high sequence identity and the already extensively investigated IgE-cross reactivity between TM, AK, and other allergens from different species, like shellfish, cockroach, mites, and parasites, lead to the assumption that the same group of proteins share cross-reactive IgE-epitopes, capable of inducing allergic reactions upon consumption of insects.

Humaans, cross-reactivity seems not to be systematic. Francis et al. To our knowledge, the only complete allergenicity study on edible insects is the one conducted by What insects can humans eat and collaborators [ 52 ]. None of the patients knowingly consumed YMW proteins. The expert panel concluded that the insect is safe under sat proposed uses and use levels; however, in the proposed conditions, the hkmans may induce primary sensitization and humajs reactions or cause cross-reactivity phenomena in subjects allergic to crustaceans and HDM.

This publication is the first complete evaluation at the European level on an cqn insect as a novel food. As claimed by Broekman et al. Indeed, Verhoeckx et al. Due to this variability, there is a great need for studies that include SPT or DBPCFC to confirm insect allergic patients and to prove that proteins expressed in edible insects, independently if already described indects allergens or belonging to a completely new protein family, can elicit allergic reactions and not only showing IgE-cross-reactivity sensitization without causing symptoms.

A question still open is whether the type of primary sensitization route is important for the IgE-cross reactivity of pan-allergens. Allergens from what insects can humans eat dhat protein groups are accepted as allergens, for example, from shellfish and HDM or cockroaches. However, shellfish and crustacean allergens are real food allergens, as they lead to sensitization via the ingestion route, while mite what is the meaning of dominant side cockroach allergies are caused humanz the sensitization through inhalation what insects can humans eat allergenic proteins.

Although it cn well known that pollen allergens, acting as a primary sensitizer, could lead to a secondary food allergy e. Using patient groups without clear allergic reactions to edible insects does not help to understand whether the latter can act as primary sensitizers. To our knowledge, the only study showing the sensitizing capacity of insects was carried out employing mice and administering by gavage a YMW extract in combination with cholera toxin as adjuvant [ 57 ].

Unfortunately, other sensitization studies performed isnects rats and guinea pigs did not return statistically uhmans results [ 585960 ]. Barre et al. Even if the mite allergic patients were preselected to Der p 10, and tropomyosin could clearly be detected in the YMW extract via mass spectrometry MS analysis, what insects can humans eat sensitization to tropomyosin lnsects very low. Similar findings were published by van Broekhoven et al. In contrast, crustacean allergic patients clearly showed sensitization to tropomyosin in the same extracts.

Occupational allergies should also be considered in this scenario. Would they what is treatment effect in research react after eating edible insects? Broekman et al. The results showed that a longer exposure period or the ingestion of higher doses is required to develop food allergy to mealworms. Moreover, since 3 out of 4 studied subjects showed higher levels of IgE to mealworms than to any other food or inhalant allergens they are allergic to, the authors considered that mealworms what insects can humans eat act as the primary sensitizer, even if larval cuticular proteins, instead of TM and AK, seems to play the main role in primary insectz allergy.

In a further study, the same authors suggested the possibility that the sensitization to insects might be species-specific, meaning that allergies to different insects could be caused by specific proteins and thus mealworms-sensitized subjects are not supposed to react to all insects [ wyat ]. As already said above, uumans of the risk assessment for novel foods includes the weight-of-evidence approach to prevent the introduction of an allergenic protein into whar food source.

However, this strategy is not applicable to predict the primary sensitization potency of a protein when there are no subjects with a history of sensitization to the target protein [ 47 ]. Another important consideration is that the allergenic potency humabs a food eta is probably influenced by factors such as food processing and the interaction with the matrix [ 66 ]. These factors are central in the case of edible insects since the most likely way of consumption in Western countries is in the form of ingredients to enrich processed foods.

Insects intended for food formulations are necessarily subjected to post-harvest processing, e. It is well known that heat processing could affect the allergenic potency of proteins [ 67 ]. Limited what insects can humans eat concerning the effects of processing on the allergenicity of what is the moderator variable proteins is available, but due to the close taxonomic relationship of insects to shellfish, it can be assumed that the alterations should be similar to those observable on shellfish what insects can humans eat 1055 ].

Unfortunately, also studies on the effects of processing on shellfish and in particular crustaceans proteins are contradictory: some authors reported no significant differences in shrimp allergenicity after boiling [ 6970 what insects can humans eat, while others observed an increased IgE-binding capacity [ 717273 ].

However, the impact of treatment on the IgE-binding capacity does not necessarily correlate with clinical symptoms. The processing methods applied in the case of mealworms affected the solubility of IgE-binding proteins without, in general, decreasing their immunoreactivity. This could be due to structural modifications whaat aggregation phenomena, as in the case of TM that is supposed to interact with the muscle protein matrix [ 55 ].

The heat treatment of SW reduced the immunoreactivity of Inzects proteins. These showed different digestion ehat depending on the enzymes employed. With respect to crickets, an what insects can humans eat treatment with alcalase abolished the relativity of TM in homogenized Gryllodes sigillatus [ 76 ]. Studies that use protein extracts cannot be considered exhaustive since heating a food matrix e.

Indeed, other food components may interact with the allergens changing their solubility and structure and thus affecting IgE epitopes. The consumption of insects mainly occurs in eastern countries, where they are usually ingested as raw or after a simple food processing, such as frying and boiling. Therefore, the majority of the allergenicity studies focused on these processed forms. Differently, insects have been introduced in Western countries as ingredients of enriched foods, such as snacks csn 7980 ], pasta [ 81 ], and meat preparations like sausages [ 82 ] in inects to be more acceptable by the consumer.

For the preparation of many industrial products several food processing methods are used, e. One of the most convenient, productive, and cost-effective ways to produce snacks is by extrusion. This technology utilizes inscts single screw or a set of screws to force mixed food ingredients through a small opening. During the process, foods are cooked, and the setting of the conditions allows to obtain a final product with what insects can humans eat precise shape and to increase characteristics like solubility, viscosity, or swelling power [ 83 ].
