Minerals in edible insects:a review of content and potential for sustainable sourcing

In response to the rapid increase in world population and subsequent demands for food,edible insects represent an alternative food source for humans that is rich in proteins,amino acids and minerals.Entomophagy is a tradition in many countries including China and Thailand,and edible insects have attracted a lot of attention in Western World due to their suitable nutrient composition,high mineral content(e.g.,Fe,Zn,Ca,Mg)and potential use as a supplement in human diet.In this study,we surveyed mineral content in seven insect orders and 67 species of mass produced and wild-harvested edible insects.The total content of essential elements in edible insects was very high in Tenebrio molitor,Bombyx mori,and Zonocerus variegatus.The heavy metal content(summarized for eight species)was below the maximum limit allowed for safe consumption.Sustainable supply of minerals derived from insect biomass is complicated due to the high variations of mineral content in insects and the potential of its change due to processing.

Immunological disturbance effect of exogenous histamine towards key immune cells

Histamine in food has attracted widespread attention due to the potential toxicity and associated health risk.However,its influences on immunological components,especially the function of key immune cells,are still poorly known.In this work,we explored the effects of exogenous histamine on the function of key immune cells such as intestinal epithelial cells,dendritic cells,and T cells.The results showed that histamine could affect the expression of allergy-related genes in CMT93 cells at a high dose of histamine.Moreover,it’s found that histamine could cause an imbalance in the levels of relevant immune factors secreted by dendritic cells and T cells,especially those related to allergy.At the same time,the proportion of MHC class IIpositive dendritic cells and the proportion of T helper 2(Th2)cells in CD4^(+)T cells increased after histamine stimulation.We concluded that the presence of a certain level of histamine in food may affect the expression of allergy-related cytokines,disrupt the balance of the immune homeostasis,and potentially lead to adverse immune reactions.This work demonstrated the importance of including the estimation of histamine’s immune safety in aquatic products rather than merely considering the potential risk of food poisoning.

Characterization of blueberry exosome-like nanoparticles and miRNAs with potential cross-kingdom human gene targets

Edible plant derived exosome-like nanoparticles(ELNs)have been shown to have multiple nutraceutical functions.However,the diversity of plant materials makes the plant derived ELN study challenging.More efforts are still needed to explore the feasible isolation methods of edible plant derived ELNs and the possible roles of food-derived ELNs in improving human health.In this study,a size exclusion chromatography based method was compared with the traditional ultracentrifugation method to isolate blueberry derived ELNs(B-ELNs),and the miRNA profile of B-ELNs was analyzed by high-throughput sequencing.A total of 36 miRNAs were found to be enriched in B-ELNs compared with berry tissue,and their potential cross-kingdom human gene targets were further predicted.Results showed that size exclusion chromatography was effective for B-ELN isolation.The most abundant miRNAs in B-ELNs mainly belonged to the miR166 family and miR396 family.Target gene prediction indicated that B-ELNs could potentially regulate pathways related to the human digestive system,immune system and infectious diseases.

Matching Dyeing and Properties of Silk Fabrics with Natural Edible Pigments

The silk fabrics were matching dyed with three natural edible pigments(red rice red,ginger yellow and gardenia blue).By investigating the dyeing rates and lifting properties of these pigments,it was observed that their compatibilities were excellent in the dyeing process:dye dosage 2.5%(omf),mordant alum dosage 2.0%(omf),dyeing temperature 80℃and dyeing time 40 min.The silk fabrics dyed with secondary colors exhibited vibrant and vivid color owing to the remarkable lightness and chroma of ginger yellow.However,gardenia blue exhibited multiple absorption peaks in the visible light range,resulting in significantly lower lightness and chroma for the silk fabrics dyed with tertiary colors,thus making it suitable only for matte-colored fabrics with low chroma levels.In addition,the silk fabrics dyed with these three pigments had a color fastness that exceeded grade 3 in resistance to perspiration,soap washing and light exposure,indicating acceptable wearing properties.The dyeing process described in this research exhibited a wide range of potential applications in matching dyeing of protein-based textiles with natural colorants.

Plant-based vaccines against viral hepatitis: A panoptic review

The traditional vaccines against hepatitis have been instrumental in reducing the incidence of some types of viral hepatitis;however,the need for cost-effective,easily distributable,and needle-free vaccine alternatives has led to the exploration of plant-based vaccines.Plant-based techniques offer a promising avenue for producing viral hepatitis vaccines due to their low-cost cultivation,scalability,and the potential for oral administration.This review highlights the successful expression of hepatitis B surface antigens in plants and the subsequent formation of virus-like particles,which have shown immunogenicity in preclinical and clinical trials.The challenges such as achieving sufficient antigen expression levels,ensuring consistent dosing,and navigating regulatory frameworks,are addressed.The review considers the potential of plant-based vaccines to meet the demands of rapid vaccine deployment in response to outbreaks and their role in global immunization strategies,particularly in resource-limited settings.This review underscores the significant strides made in plant molecular farming and the potential of plant-based vaccines to complement existing immunization methods against viral hepatitis.

Changes of structure and functional properties of rice protein in the fresh edible rice during the seed development

It has been reported that fresh edible rice has more bioactive compounds and its protein is easier to digest and has lower hypoallergenic than mature rice. In this paper, the changes in structure and functional properties of proteins at five different stages, including early milky stage(EMS), middle milky stage(MMS), late milky stage(LMS), waxy ripe stage(WS)and ripening stage(RS), during the seed development were investigated. It was found that with the seed developing, the molecular weight of fresh rice protein gradually become larger while the secondary structure changed from the highest content of disordered structure at MMS to the highest content of ordered structure at RS, which affect the surface hydrophobicity and then the functional properties of proteins, including foaming properties, emulsifying properties and oil holding capacity. Fresh rice protein at MMS has the strongest surface hydrophobicity while fresh edible rice protein at RS has the strongest oil holding capability. The results of our study can provide a theoretical basis for the application of fresh rice protein in the food industry and help to develop new fresh edible rice food.

Edible mushrooms as a potent therapeutics of subclinical thyroid dysfunction among adults,especially in obese individuals:a prospective cohort study

Background:Mushrooms are a good source of many nutrients which are potentially beneficial for chronic diseases.We speculated that due to its abundant nutrients edible mushrooms might have a beneficial effect on the prevention of subclinical thyroid dysfunction(SCTD).Therefore,we designed a large-scale cohort study to examine whether mushrooms consumption is a protective factor for SCTD in adults.Methods:This prospective cohort study investigated 6631 participants(mean age:(45.0±10.2)years;55.1%men).Edible mushrooms consumption was measured at baseline using a validated food frequency questionnaire.SCTD was defined as abnormal serum thyroid-stimulating hormone levels and normal free thyroxine.Cox proportional hazards regression models were used to examine the association of edible mushrooms consumption with incident SCTD.Results:During follow-up period,a total of 262 new cases of SCTD were identified,the incidence rate of subclinical hypothyroidism was 8.9/1000 person-years and subclinical hyperthyroidism was 7.2/1000 person-years.After adjusting potential confounding factors,the multivariable hazard ratios(95%confidence intervals)for subclinical hypothyroidism were 1.00(reference)for almost never,0.53(0.29,0.97)for 1-3 times/week and 0.30(0.10,0.87)for≥4 times/week(P for trend=0.02).It also showed edible mushrooms consumption was inversely associated with subclinical hypothyroidism in obese individuals but not non-obese individuals,the final hazard ratios(95%confidence intervals)were 0.14(0.03,0.73)(P for trend<0.01).Conclusions:This population-based prospective cohort study has firstly demonstrated that higher edible mushrooms consumption was significantly associated with lower incidence of subclinical hypothyroidism among general adult population,especially in obese individuals.

Isolation and identification of four pathogenic bacterial strains from edible snake(Elaphe carinata and Ptyas mucosus)farms with pneumonia in China

This report describes an outbreak and treatment of pneumonia and enteritis in a snake farm with more than 3000 snakes containing Elaphe carinata(one-year-old)and Ptyas mucosus(three-month-old)seedlings in Huanggang,Hubei,China.Gentamicin was used once in the early stage as treatment,administered orally with water or feed by owners,but mortality increased.Lobar pneumonia was confirmed by dissection and histopathology in infected snakes.Four main pathogenic bacteria were isolated and identified with culture and 16S rRNA sequencing:Staphylococcus sciuri,Salmonella enteritis,Vagococcus fluvialis and Providencia vermicola.Drug susceptibility tests were performed,and amikacin,gentamicin and cefitriaxone were chosen accordingly.After two rounds of treatment,the clinical signs for Elaphe carinata were under control,and the mortality was close to 0%after treatment.However,treatments for Ptyas mucosus seedlings did not work well,potentially because of poor administration technique and weak body condition.
