Sensory attributes of edible insects and insect-based foods – Future outlooks for enhancing consumer appeal

Abstract: Background Edible insects are considered a new alternative sustainable source of proteins that exhibits higher feed-conversion efficiency and has a less negative environmental impact, compared to conventional animal-derived protein sources. Highly nutritional edible insects may help solve issues of global malnutrition and food insecurity, while byproducts have the potential for practical application in the food industry, agriculture, and medicine. Despite these numerous benefits, negative attitudes toward insects as food exist in societies where it is not part of their culture to consume insects, raising barriers to the wider introduction of edible insects in the diet on a regular basis. Scope and approach In this review, we discuss the sensory characteristics, such as flavor and texture, of edible insect and insect-based foods, their contribution to consumers’ attitudes toward edible insects, and approaches to alter the quality of sensory attributes—from insect farming and processing to novel product formulation and taste education. Key findings and conclusions Sensory and visual characteristics of edible insects, and availability of information on their origin and safety, are important factors in consumer appeal and their willingness to try eating insects in the future. Flavor and texture of edible insects depend largely on the insect species, its development stage, and the way it is processed. Recent findings on insect production, processing, and formulation of insect-based foods, as well as ways to increase familiarity with edible insects, demonstrate the potential to enhance the acceptability of insects as a novel food.

Crowdsourcing Mechanism for Trust Evaluation in CPCS Based on Intelligent Mobile Edge Computing

Abstract: Both academia and industry have directed tremendous interest toward the combination of Cyber Physical Systems and Cloud Computing, which enables a new breed of applications and services. However, due to the relative long distance between remote cloud and end nodes, Cloud Computing cannot provide effective and direct management for end nodes, which leads to security vulnerabilities. In this article, we first propose a novel trust evaluation mechanism using crowdsourcing and Intelligent Mobile Edge Computing. The mobile edge users with relatively strong computation and storage ability are exploited to provide direct management for end nodes. Through close access to end nodes, mobile edge users can obtain various information of the end nodes and determine whether the node is trustworthy. Then, two incentive mechanisms, i.e., Trustworthy Incentive and Quality-Aware Trustworthy Incentive Mechanisms, are proposed for motivating mobile edge users to conduct trust evaluation. The first one aims to motivate edge users to upload their real information about their capability and costs. The purpose of the second one is to motivate edge users to make trustworthy effort to conduct tasks and report results. Detailed theoretical analysis demonstrates the validity of Quality-Aware Trustworthy Incentive Mechanism from data trustfulness, effort trustfulness, and quality trustfulness, respectively. Extensive experiments are carried out to validate the proposed trust evaluation and incentive mechanisms. The results corroborate that the proposed mechanisms can efficiently stimulate mobile edge users to perform evaluation task and improve the accuracy of trust evaluation.
