Gummy candies are nutritionally poor foods; however, they have a large consumer market. Enhancing these products with nourishing and/or functional matrices is a challenge. This study aimed to develop the features of a gummy candy probiotic, containing Bifidobacterium lactis HN019, and evaluate its effectiveness in inhibiting Streptococcus mutans UA159. The candy was suitable for probiotic development, whose viable bacterial count was 8.54 Log CFU/g in the ready-to-eat product; high viability was maintained during the 28-day shelf life. Additionally, the rate of probiotic survival under in vitro gastrointestinal simulation was 98% and 93% in the ready-to-eat product and after shelf life, respectively. The sensory analysis revealed scores over 8.0 in all attributes evaluated. Lastly, the inhibition test of S. mutans UA159 showed 25% and 98% inhibition, with 10% and 20% xylitol respectively. Probiotic and xylitol gummy candy is a potential functional food and can target a niche food market, such as teenagers.

Trace elements such as selenium (Se) and zinc (Zn) are essential elements in the human body, while cadmium (Cd) has no physiological function. A high proportion of people consume dietary supplements to enhance the performance of the body or alter the nutrient contents within the body. Therefore, this study was conducted to evaluate the interaction effects of several popular dietary supplements on the bioaccessibility of Se, Zn and Cd in rice with the hope of identifying dietary supplements that can increase rice Se and Zn bioaccessibility but decrease rice Cd bioaccessibility. The results from in vitro gastrointestinal simulation tests showed that the bioaccessibility of these elements in rice was in the order of Cd (52.07%) > Zn (36.63%) > Se (10.19%) during the gastric phase and Zn (26.82%) > Cd (18.72%) > Se (14.70%) during the intestinal phase. The bioaccessibility of Se during the intestinal phase was greater than that during the gastric phase, and the bioaccessibility of Zn and Cd were the opposite. The bioaccessibility of Se significantly increased in response to vitamin C (VC), vitamin E (VE), vitamin B6 (VB6) and vitamin B9 (VB9), especially VC, which also increased the bioaccessibility of Zn and decreased that of Cd. Procyanidins (OPC), methionine (Met) and coenzyme Q10 (Q10) significantly reduced the bioaccessibility of Se. These results suggest that the reasonable use of dietary supplements can effectively regulate the in vivo contents of trace elements, which provide valuable information for developing health interventions to address problems for specific people, especially selenium-deficient people.
