Wax apple fruit ( Alston cv. Taaptimjan) is a tropical fruit with many nutritional bioactive compounds and high economic value. However, when fully ripe, the thin-skinned fruit is highly susceptible to physical damage and microbial spoilage that significantly reduce its commercial value. The present study was aimed to find a suitable ripening stage between the ripe and overripe wax apple fruits for developing a value-added beverage specifically cider. The chemical profiles of ripe and overripe wax apple juice and cider were determined by measuring sugar, acid, alcohol, mineral, proximate, ascorbic acid, amino acid, antioxidant, and volatile levels. Overall, the results showed significant variations. The physicochemical and proximate analysis showed highest values for ripe fruit juice than overripe fruit juice and the cider samples. The amino acids in the samples were found almost at similar levels. Polyphenolic content and antioxidant activities were higher in ciders than in unfermented juices. In addition, the overripe fruit cider had more volatile compounds than ripe fruit cider and unfermented juices. Overall, the overripe fruit is suitable for producing cider, whereas the ripe fruit is more suitable for the unfermented beverages.

Aim: This study evaluated effects of various solutions on color stability and surface hardness of a nanohybrid dental composite in simulated oral environments.
Materials And Methods: Sixty-four composite disks were fabricated and randomly allocated into eight groups ( = 8 per group): Artificial saliva (AS), Biotene (B), passion fruit juice (PFJ), orange juice (OJ), Sprite (S), Coca-Cola (CO), apple cider vinegar (ACV), and cranberry juice (CJ). Specimens were immersed in respective solutions at 37°C for 28 days.

Background: Fruits are an important source of flavonoids, and greater intake of dietary flavonoids in older adults has been shown to be associated with decreased risk of dementia. It is unclear whether this relationship is similar or different between younger adults and older adults.
Objectives: We examined for associations between midlife and late-life intake of flavonoid-rich fruits and incident dementia.

This study aimed to investigate the impact of different strains of on malolactic fermentation (MLF), antioxidant activity, and aroma of ciders. A commercial strain of and six indigenous strains were co-inoculated into apple juice to induce simultaneous alcoholic fermentation (AF) and MLF. The findings indicated that despite belonging to the same species, the different L.

Patulin, a toxic mycotoxin, can contaminate apple-derived products. The FDA has established an action level of 50 ppb (ng/g) for patulin in apple juice and apple juice products. To effectively monitor this mycotoxin, there is a need for adequate analytical methods that can reliably and efficiently determine patulin levels.
