Objectives: We aimed to examine health-related nutritional knowledge and dietary behavior related to caffeine intake among high school students ( = 310) in the Yongin region of Korea.

Methods: Data were collected using a face-to-face survey, and analyzed using chi-square test, - test, and logistic regression analysis.

Results: The level of caffeine intake in respondents was divided into low (< 30 mg/d; = 208) and high caffeine intake groups (> 30 mg/d; = 102).

Fermented kale juices using four types of lactobacilli were produced in the present study. After 48 h of fermentation time, viable cell counts of all ferments reached an above 10 CFU/mL. The viability of the ferments after cold storage in the refrigerator for 4 weeks showed 10 CFU/mL in all ferments.

Shinseoncho and kale were made into green vegetable juices by building block [shinsenocho branch (SB), shinsenocho leaf (SL), kale branch (KB), and kale leaf (KL)]. Fluctuations in their phenolic contents and antioxidant capacities were analyzed during refrigerated storage at 4°C for 28 days. Total polyphenolic contents of leaf parts showed a decreasing tendency after 4 days (SL) or 7 days (KL), whereas branch parts showed fluctuating values during the entire storage period.

Citron seed extracts (CSEs) were made using distilled water (CSEW), ethanol (CSEE), and n-hexane (CSEH), to measure the total polyphenol contents, DPPH and ABTS radical scavenging activities, and anti-complementary activity. The total polyphenol content was observed the highest in CSEE (188.71 μg/mL), and occurred in the following order: CSEE>CSEW (141.

Shinseoncho and kale were divided into stem [shinseoncho stems (SS) and kale stems (KS)] and leaf parts [shinseoncho leaves (SL) and kale leaves (KL)] and made into green vegetable juices for analyses of nutritional compositions and antioxidant activities. Higher values of total acidity were observed in SL (0.736%) and KL (0.

Trifoliate orange seed extracts (TSEs) were prepared from different solvents, water (TW), ethanol (TE), and n-hexane (TH), and assessed for their antimicrobial activities against six gram-negative food-borne pathogens (Escherichia coli KCTC 1039, Escherichia coli O157:H7 ATCC 43895, Salmonella Enteritidis ATCC 3311, Salmonella Typhimurium KCCM 11862, Shigella sonnei KCTC 2518, and Vibrio parahaemolyticus ATCC 17802). Among the tested TSEs, TE and TH showed a slight inhibition activity on V. parahaemolyticus ATCC 17802, but a good growth inhibition activity on Sal.

Trifoliate orange seed extracts (TSEs) were made using either distilled water (TW), ethanol (TE), or n-hexane (TH), to measure total polyphenol contents, DPPH and ABTS radical scavenging activities, and anti-complementary activity. The results showed that the total polyphenol content showed higher value at TE (235.24 μg/mL, p<0.

Article Synopsis
  • - The study focused on enhancing the production of Cordyceps sinensis using a submerged culture method by experimenting with different carbon sources, primarily rice bran and citrus peel for optimal glucosamine and exopolysaccharide (EPS) yield.
  • - The researchers established an optimal nutrient mix (including rice bran, molasses, and other components) and conditions (25°C and 5-6 days culture time) that maximized EPS productivity with significant immune-boosting properties.
  • - Adding citrus peel to the culture considerably boosted both EPS and glucosamine content while also increasing anti-complementary (up to 80.8% activity) and antioxidant (AEAC value of 384.6 mg/100g) effects

This study investigated the growth promoting effects of yeast extract (YH) fed to Sprague-Dawley male rats (3 weeks old) for 4 weeks. The negative (N)-control and positive (P)-control groups were given a daily oral administration of saline and foremilk (1 g/kg of BW), respectively, and the YH-1 and YH-2 groups were given daily administrations of YH (0.5 and 1 g/kg of BW, respectively).

To reduce the pungency of Capsicum without the loss of its biological activity, a Capsicum sp. was fermented by Bacillus subtilis with the addition of Rapidase enzyme. At 1 day of fermentation, the capsaicin content of the Capsicum ferment with Rapidase had sharply decreased from an initial content of 11.
