This paper examines how technological innovation in next-generation probiotics shapes consumer trust through the lens of perceived safety. Rapid advances—spanning conventional cultures (Tier 1), postbiotics (Tier 2), and engineered microbial strains (Tier 3)—are transforming functional food architectures, yet consumer trust remains a critical determinant of their successful development, application, and adoption. Drawing on interdisciplinary evidence from food microbiology, consumer perception research, and regulatory analysis, this study examines and evaluates how these distinct technological innovation tiers alter public risk dynamics. Findings indicate that processing methodologies, media framing, and the spread of misinformation significantly influence public perceptions of microbial legitimacy, while the “Animation Gap” and “Contamination Anxiety” introduce qualitatively new cognitive friction points. Furthermore, regulatory inconsistencies across jurisdictions and variability in health claim substantiation further complicate market uptake. Streamlined case-based evidence highlights physical stability, sensory performance, and explicit value metrics that determine whether technological innovations are trusted or rejected by consumers. The paper argues that bridging the gap between scientific innovation and public acceptance requires proactive communication strategies, ethical marketing practices, and participatory engagement strategies grounded in empirical integrity. In addition, digital ecosystems, including social media and algorithm-driven content exposure, play an increasingly influential role in amplifying technology neophobia, underscoring the need for robust, targeted, evidence-based public communication in the evolving landscape of probiotic and functional food innovation.

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 and environmentally responsible and sustainable food future for humanity. The findings revealed 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.

Food fortification is a critical tool for addressing global micronutrient deficiencies, yet existing frameworks often prioritize industry standards and policy enforcement over consumer engagement. Despite numerous fortification initiatives, public awareness, transparency, and accessibility remain inconsistent, leading to gaps in effectiveness and trust. This study builds on examining existing fortification frameworks, highlighting their strengths and limitations. While current models effectively determine fortification needs, feasibility, and industry compliance, they frequently overlook harmonization with existing health interventions, policy integration, and consumer inclusion. This presentation explores how fortification can be reframed through a consumer-centred approach, ensuring that individuals are informed, empowered, and actively engaged in food fortification policies and practices. Key challenges, such as limited public awareness, labelling inconsistencies, and lack of consumer consultation, are analysed alongside solutions that emphasize transparency, education, and policy integration. By bridging the gap between fortification efforts and consumer needs, governments and industry stakeholders can enhance public trust, compliance, and long-term health outcomes. Informed by existing gaps in fortification policy, this study argues for a revised model that strengthens enforcement while fostering consumer participation, ultimately creating a more sustainable and equitable food fortification system.

The human diet comprises both plant and animal protein, with considerable regional variation and greater reliance on animal protein in richer Western nations. Animal protein is less efficient in its use of land, water and energy resources than plant protein, and is associated with significant atmospheric emissions contributing to climate change. It also has adverse health consequences for many consumers. Food security worldwide is threatened by a growing reliance on animal protein, with developing countries increasing consumption of animal products in response to growing prosperity and a desire to emulate Western diets. Although a range of drivers contributes to some consumers shifting to more plant-rich diets, this trend is insufficient to stem the rapid rise in meat consumption. Meat products are being developed using cell-based technologies, but these are yet to become commercially available. They also challenge the animal-plant protein dichotomy. This dynamic situation needs to be managed nationally and internationally to avert the dire consequences of an over-reliance on animal protein.

Australia, which has one of the world’s highest per capita meat consumption rates, is hesitant toward adopting alternative proteins. This study examines consumer perceptions of protein alternatives and their perceived safety, nutritional value, health risks, cost and willingness to incorporate them into their diets. Using a mixed-methods approach, a survey of 520 Australians aged 18 to 64 revealed that while alternative proteins are viewed as occasional dietary options, younger consumers—despite their tendency to favour traditional food choices—show interest in plant-based milk and algae-based products. However, across all generations, interest in regular consumption of plant-based meats, insects and cultured meat remains low. These findings highlight evolving attitudes, challenges to market growth, and the importance of fostering greater consumer trust to encourage wider adoption of alternative proteins. Addressing generational differences in adoption and resistance will be essential for expanding market penetration.

Methane, a potent greenhouse gas, has a global warming potential over 84 times greater than carbon dioxide over its relevant lifespan. Current atmospheric methane concentrations are at a record high, significantly contributing to near-term climate warming. Agriculture, particularly livestock, is a major methane emitter, accounting for 40% of global total emissions, with enteric fermentation in ruminants accounting for 90% of agricultural methane emissions. The recent interest in mitigating these emissions has centered on seaweeds, such as Asparagopsis taxiformis, which contain bromoform, a bioactive compound shown to significantly reduce enteric methane production. However, bromoform raises environmental concerns including its potential carcinogenicity and ozone-depletion effects. This study systematically reviews the environmental and ozone-related impacts of scaling up seaweed production for enteric methane reduction in livestock. Key challenges include sustainability, biodiversity risks, and upstream emissions possibly offsetting the methane reduction gains. Animal health concerns, such as reduced weight gain and mucosal irritation, also warrant attention. Additionally, supply chain logistics, cultivation and harvesting practices, and bromoform retention remain underdeveloped. The limited assessment of the ozone depletion potential underscores the need for further research. These findings highlight the need for techno-feasibility and life cycle assessment before scaling up seaweed-based solutions. A broader approach to methane mitigation, beyond feed additives, is essential to ensure sustainable outcomes for livestock agriculture.

Meals served to children should not only satisfy hunger and taste preferences but also be nutritionally adequate. Nutrition in early childhood is critical, as children spend a significant portion of their day in kindergarten or preschool, making these settings key contributors to their overall dietary intake. With the rising prevalence of nutrition-related health conditions among children, early interventions are essential for developing and establishing lifelong healthy eating habits. This study assessed the nutritional value and quality of children’s diets in two distinct settings: kindergartens in Wroclaw, Poland, and preschools in Sydney, Australia, evaluating their alignment with the planetary health diet. The research analysed 10-day menu cycles from five kindergartens in Wroclaw and the contents of lunchboxes from five preschools in Sydney’s Upper North Shore area. A total of 100 menus were reviewed in Poland, while 100 children’s lunchboxes were assessed in Australia. Different analytical methods were employed: the Diet 6D software program for the Polish menus and the Food Consumption Score for the Australian lunchboxes. Both methods revealed dietary imbalances, such as excessive intake of protein, vitamin A, salt, and sugar, alongside deficiencies in calcium, vitamin C, and vitamin D. The study concluded that children’s diets should adhere to nutritional guidelines, meeting both Polish and Australian standards, and align with the principles of the planetary health diet. To achieve this, nutritional education is essential for kindergarten staff in Poland, while targeted educational interventions are needed for parents and children in both Poland and Australia, promoting health and environmental sustainability through better nutrition.
