    Functional pet food has grown rapidly, in line with the accelerated humanization of pets, growing attention to relations between diet and health, and mounting sustainability awareness. The article provides a critical overview of recent developments and new trends in functional pet food, combining data from published works, patents and market-driven innovative companies. The current trends depict a transition from single-nutrient fortification to integrated nutrition interventions through modulation of gastrointestinal health, immunity, metabolism, cognition and age-associated conditions. Special attention is dedicated to probiotics, prebiotics, postbiotics, polyphenols and novel protein sources, as well as innovations in processing and delivery technologies. The review highlights ongoing issues on the relevance of study design, available long-term safety information and our capacity to mechanistically underpin claims with respect to function. Because this review maps clusters of innovation and clusters of underdeveloped knowledge, it offers a roadmap for the translational pathway from scientific discovery to commercialization. The results highlight a call for harmonized methods, longer duration studies and integrative omics-based approaches in order to improve the evidence basis formulation and responsible marketing of future functional pet food products following credible, safe and sustainable strategies.

    The present study aimed to investigate the in-vitro antidiabetic activity of collagen hydrolysate (CH) from Asian bullfrog skin and its application as a bioactive compound in dark chocolate bars. Papain (3% [w/w]) was used to obtain CH with a simultaneous conjunction of ultrasound. CH possessed α-amylase inhibitory activity with an IC<inf>50</inf> value of 3.60 mg/mL, while results from inhibition reaction kinetics revealed that CH inhibited α-amylase in a non-competitive mode. Different concentrations (0.5, 1.0, and 2.0% [w/w]) of CH were then fortified into dark chocolate bars, and the physicochemical characteristics, breaking strength, and rheological behaviour of the resulting chocolate were investigated and compared with a control (without CH addition). A higher level of CH significantly enhanced antidiabetic activity against α-amylase (p ≤ 0.05) in chocolate bar. Chocolate bar with 2% CH complied with the nutritional claim requirement for ‘source of protein’ with lower fat content and energy value, while sensory evaluation revealed good organoleptic properties.

    Here we test a method of incorporating of plant extracts into popular snack foods to help control diabetes. Since some fresh vegetables contain antidiabetic compounds, ultrasound-assisted extraction was used to optimize their extraction of from spring onions, bunching onions, and celery for later incorporation into crackers. We compared various concentrations of ethanol used during extraction, after which they were exposed to an ultrasound processor whose amplitude and sonication time were also varied. The optimal extraction conditions were found to be an ethanol concentration of 44.08%, an amplitude of 80%, and a sonication time of 30 min. This resulted in the highest level of α-glucosidase inhibitory activity (i.e., 1,449.73 mmol ACE/g) and the highest extraction yield (i.e., 24.16%). The extract produced from these optimum conditions was then used as a constituent component of crackers at 0.625%, 1.25%, or 2.5% w/w. These biscuits were then produced at baking temperatures of 140°C, 150°C, or 160°C. We then measured the physical characteristics and bioactivities of sample biscuits from each treatment. We found that biscuits containing 2.5% vegetable combination extract and baked at 140°C had the highest total phenolic content, the strongest antioxidant performance, and showed the most substantial antidiabetic and antiobesity effects. Here we establish conditions for the effective extraction of antidiabetic functional ingredients via ultrasound from green leafy vegetables. We also provide a method of using these ingredients to prepare crackers with the aim of developing a functional antidiabetic snack food.
