This review article aims to provide an up-to-date overview of the main determinants of consumers’ acceptance of novel foods (new foods and ingredients) in the EU with emphasis on product’s intrinsic properties (sensory characteristics) and individual factors (socio-demographics, perceptive, psychological) by adopting a systematic approach following the PRISMA methodology. Case studies on terrestrial (i.e., insects, cultured meat and other animal origin products, plant-based food including mushrooms, plant-based analogues, pulses, and cereals) and aquatic systems (i.e., algae and jellyfish) are included focusing on age-related and cross-national differences in consumer acceptance of novel foods and ingredients. General trends have emerged that are common to all the novel foods analysed, regardless of their aquatic or terrestrial origin. Aspects such as food neophobia, unfamiliarity, and poor knowledge of the product are important barriers to the consumption of novel foods, while healthiness and environmental sustainability perception are drivers of acceptance. Sensory properties are challenging for more familiar ingredients such as plant-based food (e.g., novel food made by pulses, mushrooms, cereals and pseudocereals). Results are discussed in terms of feasibility of introducing these products in the EU food systems highlighting strategies that can encourage the use of new ingredients or novel foods.

In Western societies, the unfamiliarity with insect-based food is a hindrance for consumption and market development. This may depend on neophobia and reactions of disgust, individual characteristics and socio-cultural background, and risk-perceptions for health and production technologies. In addition, in many European countries, the sale of insects for human consumption is still illegal, although European Union (EU) and the European Food Safety Authority (EFSA) are developing regulatory frameworks and environmental and quality standards. This research aims to advance the knowledge on entomophagy, providing insights to improve consumer acceptance in Italy. This is done by carrying out the characterization of a sample of consumers according to their willingness to taste several types of insect-based food and taking into account the connections among the consumers’ features. Thus, the dominance-based rough set approach is applied using the data collected from 310 Italian consumers. This approach provided 206 certain decision rules characterizing the consumers into five groups, showing the consumers’ features determining their specific classification. Although many Italian consumers are willing to accept only insects in the form of feed stuffs or supplements, this choice is a first step towards entomophagy. Conversely, young Italian people are a niche market, but they can play a role in changing trends.

Purpose: The purpose of this paper is to investigate the trends and prospects for the development of the halal market for Italian foods, with a focus on pasta production as one of the most valued products of the Made in Italy brand. The analysis takes into consideration drivers and obstacles for developing halal orientation strategies in world and internal markets and opportunities and threats for Italian food firms. Design/methodology/approach: Market dynamics were investigated by a forecasting tool, the Delphi method, which aims to explore future market trends and give suggestions for firm strategies and policy intervention. Besides firms, other experts involved in the Italian halal food sector were interviewed. Answers were organised according to the level of importance given to the different issues and to the level of agreement between the opinions of the experts. These findings were then discussed in relation to the contexts, both external and internal to companies, that had given rise to such opinions. Findings: The halal food market represents a good opportunity for enlarging the overseas markets for Italian products and producers. Several external and internal factors related to the demographic, the institutional, the market and the firm contexts, emerged. The challenges that non-Islamic countries, markets and firms face in the adoption of halal strategies are mainly due to the institutional context, to the scarce awareness of halal principles and practices, and to some suspicion of Islamic food and culture that does not yet seem well-known and accepted on the domestic market. Originality/value: The Islamic food market has still to be fully explored in Italy, this is despite strongly emerging demand and a growing number of firms showing interest in implementing halal certification and entering new Islamic markets. The paper findings contribute to the scarce empirical literature about the halal market in Italy and give some recommendations both for supporting further studies, identifying preliminary implications and suggesting policy measures.

To address global food security, new strategies are required in view of the challenges represented by Climate Change, depletion of natural resources and the need to not further compromise the ecosystems’ quality and biodiversity. Food losses and waste (FLW) affect food security and nutrition, as well as the sustainability of food systems. Quantification of the adverse effects of FLW is a complex and multidimensional challenge requiring a wide-ranging approach, regarding the quantification of FLW as well as the related economic, environmental and social aspects. The evaluation of suitable corrective actions for managing FLW along the food supply chain requires a system of sound and shared benchmarks that seem still undefined. This review aims to provide an overview of the environmental, economic and social issues of FLW, which may support policy measures for prevention, reduction and valorization of food wastes within the food supply chain. In fact, detection of the hotspots and critical points allows to develop tailored policy measures that may improve the efficiency of the food supply chain and its sustainability, with an integrated approach involving all the main actors and considering the several production contexts.
