Tea is a popular beverage with potential health benefits for those who consume it regularly. Tea products with health claims require scientific evidence based on clinical trials with generally accepted scientific data and newly developed scientific data. Tea products have been labelled FOSHU in Japan, claiming to reduce body fat and cardiovascular risk. In The USA, health claims on tea cannot be recommended and categorized as Qualified Health Claims. In Europe, health claims for tea still required further research to provide accepted scientific data. This review aims to explain the position of tea products based on the perspective of the regulatory framework of food health claims in the different official agencies in the United States, Europe, and Japan.

2022
Özge Duygu Okur
This study aims to reveal the quality properties of yogurt enriched with walnut during cold storage (4°C) for 28 days. Five sets of yogurt types were produced by using walnut at varying rates (A: 0% (control), B: 1%, C: 2.5%, D: 3.5%, E: 5%). Physicochemical, sensory, phenolic contents and antioxidant properties of yogurt samples was investigated during the 1st, 7th, 14th, and 28th days of storage. The study was conducted to optimize the walnut addition level to obtain better quality yogurt as a functional food. It was determined that the walnut enrichment affects the gross chemical component of yogurt samples. Yogurt sample with %5 walnuts (E) had the highest total phenolic and antioxidant activity content (respectively 1027.50 mg GAE/kg, 19.95 mM TE) among the samples. The yogurt sample with the highest sensory attribute score was the one containing 1% walnuts. Therefore, it was concluded that yogurt added with walnut could serve as functional yogurt beneficial for human health.

2020
Elif Öztürk | Gülden Ova
In this study, wheat flour was substituted with the following ratios of the raw (RCBH) and leached (LCBH) cocoa bean hull (CBH) in pound cakes (PC) (CBH/wheat flour ratios: 20/80 (20%), 30/70 (30%) and 40/60 (40%)), respectively. The proximate composition and the content of bioactive compounds in the cake samples for each weight ratio of RCBH and LCBH and in the hulls were evaluated. Fiber, ash, total antioxidant activity (TAA) and total phenolic compound (TPC) contents increased with the CBH content in the cakes. No significant difference was found in the specific volume among the cake samples. Based on the results of the textural analysis, all cake samples showed higher hardness, lower springiness and cohesiveness than those of the control cake. Regarding to the color of the crumb and crust, the 40% LCBH and RCBH cakes presented the lowest L*, a* and b* values. According to the Principal Component Analysis (PCA), it was observed that the properties with respect to the cell uniformity, adhesiveness, sweetness, oiliness and humidity of the 20LCBH and 20RCBH cakes can be distinguished clearly from the other flour substituted cakes.

Aronia melnocarpa, commonly known as chokeberry, originates from the eastern region of North America and belongs to the Rosaceae family within the Maloideae subfamily. The sour taste of fresh chokeberries makes them infrequently eaten as is, but they find extensive use in the food industry for creating fruit juices, fruit teas, wines, jams, jellies, and dietary supplements. Chokeberries represent a source of a wide range of bioactive compounds with potential health benefits for humans. Among the effects supporting human health are antidiabetic, anti-inflammatory, antimicrobial, and anticancer properties, as well as protection for the heart, liver, and nervous system. The abundant presence of polyphenols, such as phenolic acids, flavonols, anthocyanins, flavanols, and proanthocyanidins, plays a crucial role in conferring the remarkable bioactivity of chokeberries. These compounds are responsible for many of the health benefits associated with the consumption of chokeberries. Chokeberry fruits and their derived products showcase notable antioxidant properties and have the potential to promote health by effectively reducing the formation of free radicals. In this review, a comprehensive analysis of scientific research has been conducted to explore the polyphenolic compounds found in chokeberries, as well as their antioxidant potential. The findings in this review are likely to have a significant impact on future research focused on developing functional food products based on chokeberries. Chokeberries possess the potential to serve as food constituents intentionally crafted to augment antioxidant capacity. However, similar to other natural plants and medicinal products, conducting extensive research is crucial to assess the antioxidant potential, safety, and mechanisms of action of chokeberries. Therefore, the aim is to make a positive contribution to the continuation of research on the positive effects of chokeberry on health.
