Abstract

The increasing production and consumption of meat globally have raised serious concerns about environmental pollution, land and water requirements, greenhouse gas emissions, biodiversity loss and human health. Ensuring adequate protein requirement is one of the biggest challenges to food security. Therefore, new-generation meat and dairy analogues from a wide range of novel protein sources, such as upcycled plant materials, cultured cells, fermentation processes, fungi, algae and edible insects, have gained significant interest from both researchers and consumers. This study aims to review alternative proteins, meat and dairy analogues, and assesses their potential for an affordable, health-conscious, environmentally responsible and sustainable food future for humanity. The findings reveal that for the fourth industrial revolution in food production to successfully drive a protein transition, consumers must be engaged from the outset — including in the marketing of new products — to prevent rejection and resistance to dietary change. Clear and compelling communication is also needed to explain why and how novel meat and dairy alternatives surpass direct plant-based options, which have long offered significant benefits and remain a reliable and satisfying food choice.

Abstract

Alternative plant and seaweed protein sources other than soy and pea have gained significant interest as sustainable replacements of animal proteins in the last decades. However, despite a large food safety literature base, there are concerns about their food safety risks. The current study aims to synthesize the existing knowledge and gaps on safety risks associated with brewers' spent grain (BSG), grapes, hazelnuts, potatoes, pumpkins, and seaweed. A systematic review between 2003 and 2023 was conducted in the PubMed database to identify microbial, chemical, mycotoxins, heavy metals, and allergenic risks in the key commodities. The records obtained were exported into an online reference management platform, screened by inclusion and exclusion search strings, and the duplicates were removed. Finally, two reviewers assessed the eligibility of the full-text articles. The findings demonstrated that 9127 papers were identified, and 1639 of them were left for eligibility assessment. The reviewers finally included 144 articles. Amongst the commodities, the most safety studies were on grapes, with 55 papers, followed by potatoes (n=38), seaweed (n=21), hazelnuts (n=19), pumpkin (n=9), and BSG (n=2), respectively. Based on the risk type, heavy metals were the most studied ones, with 49 papers, followed by mycotoxins (n=31), microbial risks (n=23), chemical contaminants (n=21), and allergenic risks (n=20), respectively. To meet the growing need for plant and seaweed proteins, their food safety aspects should be extensively studied to deliver safe, healthy, and affordable substitutes based on robust safety standards.
