It evaluates their physicochemical properties, thermal stability, and rheological behaviour. Three honey varieties, one of which was Lavender Honey (LH), were incorporated into cacao printlets to assess their impact on structural integrity and compatibility with Vitamin D3 (VitD3), a bioactive compound known for immune system enhancement. Including honey aims to improve the nutritional profile, enhance the taste, and potentially increase the bioavailability of VitD3, which is limited by its hydrophobic nature and low oral absorption. Thermal analysis showed that honey-infused cacao printlets maintain a liquid-like state under ambient conditions and exhibit stability up to the printing temperature of 38 °C. Rheological assessments demonstrated that both individually and in combination, increased honey concentrations and VitD3 incorporation enhance viscosity. These changes improve printability and structural integrity during 3DP. While raw LH demonstrated antibacterial activity, no antibacterial efficacy was observed in the LH-based printlets after incubation. LH at a 10% concentration emerged as the optimal formulation, demonstrating balanced structural properties and effective miscibility with VitD3.</div><div>This study highlights how raw Greek honey produced without chemical miticides, has the potential to enhance the functionality and palatability of 3D-printed health supplements.

Therefore, we aimed to assess the suitability of insects as source ingredients for surimi, a widely-used, intermediate food material. Mealworm (<em>Tenebrio molitor</em> L.) and two-spotted cricket (<em>Gryllus bimaculatus</em> L.) surimi were prepared, and their physicochemical and rheological properties were examined. Myofibrillar protein-rich fractions were obtained using the washing and pH shift methods. For the pH shift method, the myofibrillar proteins were extracted at acid (pH 2) or alkaline (pH 11) conditions, and surimi gel was prepared by heating myofibrillar protein-rich fractions. The pH shift method resulted in a higher surimi yield from edible insects than the washing method, whereas the washing method resulted in a higher surimi yield from tilapia (<em>Oreochromis niloticus</em>) and chicken breast (<em>Gallus gallus domesticus</em>). After acid treatment, lipid oxidation increased in all samples; however, edible insect surimi exhibited lower oxidation levels than tilapia and chicken breast surimi. Insect proteins, except for acid-treated mealworm proteins, successfully formed gel structures upon heating, resulting in softer gels than those obtained from tilapia and chicken breast. Consequently, the pH shift method resulted in elevated insect surimi yield, and the alkaline treatment was more appropriate for producing fine-quality edible insect surimi. Our study demonstrates the usefulness of edible insects as surimi ingredients, particularly for soft-gel food production. These findings emphasize the innovative application of edible insects in the food industry, suggesting the possibility of expanding their use as alternative protein food ingredients.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"10 ","pages":"Article 100952"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11698935/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142930805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare nutritional values and harmful compounds in IND vs. HM versions of four common foods: plumcake, fish sticks, tomato sauce, and cereal bars. The HM foods were prepared using similar recipes to their industrial counterparts, avoiding technologies and ingredients not available at home. The analysis revealed identical nutritional compositions between the IND and HM versions. Acrylamide (AA) and Maillard reaction (MR) products, considered potentially harmful, showed comparable levels across the food pairs, though HM versions showed slightly higher levels in some cases. AA was undetectable in IND plumcake and HM cereal bars, while HM fish sticks had higher AA content than the industrial version. These findings indicate that homemade foods do not necessarily offer superior nutritional quality or lower levels of harmful compounds compared to industrial products.
