  • Chopped garlic was added to beef to determine its effect on the protein digestion during storage and heat treatment. The digestibility of raw beef without garlic was not significantly changed during storage at $4^{\circ}C$, but increased as garlic added and aging time increased. The optimal aging time and amount of garlic added was varied with heating time. Trypsin inhibitor did not change the digestibility of beef due to its thermal inactivation. Gel chromatography revealed that the lower molecular weight peptides(2,200~6,150 dalton) were shown in beef-garlic mixture through aging and heating procedure. When aged beef with garlic was digested with four-enzyme system, the soluble portion was increased significantly in comparison with that from raw beef without garlic. Protein quality of beef, as measured by computed PER(C-PER), was improved from 2.14 of raw beef to 2.50 of aged beef with chopped garlic.

  • This study investigated the quality characteristics and biological activities, such as antioxidant, whitening, anti-diabetes, and anti-inflammatory activities, of yellow garlic, by simplify processing time and manufacturing process compared with black garlic. Extracts were prepared various ratios of water and ethanol solvent [water : ethanol (v/v)=100:0, 70:30, 50:50, 30:70, 0:100] from yellow garlic. Alliin content of yellow garlic showed no difference compared with fresh garlic, whereas S-allyl cysteine content of yellow garlic was higher than that of fresh garlic. Alliin content of yellow garlic extracts increased in an ethanol concentration-dependent manner. Total phenol and flavonoid contents were highest in 100% ethanol extract. DPPH and ABTS radical scavenging abilities did not show significant differences among 0~70% ethanol extracts, whereas 100% ethanol extract showed the highest contents of 93.45% and 91.46%, respectively. Tyrosinase and ${\alpha}$-glucosidase inhibitory activities were also highest in 100% ethanol extract, but did not show significant differences among the extract solvents. Water and ethanol extracts from yellow garlic showed anti-inflammatory effects by modulating production of NO and cytokines at a concentration of $100{\mu}g/mL$. We suggest that yellow garlic has antioxidant, whitening, anti-diabetes, and anti-inflammatory activities and can be used as a functional material similar to black garlic.

  • Allium sativum (Family Amaryllidaceae or Liliaceae) is used worldwide for various clinical uses like hypertension, cholesterol lowering effect, antiplatelets and fibrinolytic activity etc. Due to these common house hold uses of Allium sativum, as a herbal supplements, and failure of patients to inform their physician of the over-the-counter supplements they consume leads to drugnutrient interactions with components in herbal supplements. Today these types of interactions between a herbal supplement and clinically prescribed drugs are an increasing concern. In vitro studies indicated that garlic constituents modulated various CYP (cytochrome P450) enzymes. CYP 3A4 is abundantly present in human liver and small intestine and contributes to the metabolism of more than 50% of commonly used drugs including nifedipine, cyclosporine, erythromycin, midazolam, alprazolam, and triazolam. Extracts from fresh and aged garlic inhibited CYP 3A4 in human liver microsomes. The in vivo effects of garlic constituents are found to be species depended and the dosing regimen of garlic constituents appeared to influence the modulation of various CYP isoforms. Studies have indicated that the inhibition of various CYPs by organosulfur compounds from garlic was related to their structure also. Studies using in vitro, in vivo, animal and human models have indicated that various garlic constituents can be the substrates, inhibitors and or inducers of various CYP enzymes. The modulation of CYP enzyme activity and expression are dependent on the type and chemical structure of garlic constituents, dose regime, animal species and tissue, and source of garlic thus this review throws light on the possible herb drug interaction with the use of garlic.

  • In the present work antidotal effect of dietary garlic was studied on lead-intoxicated rat. One of 5 groups of young Wistar sp. male rat, aged 4 weeks for control were fed only normal diet. Lead (25 ㎎/㎏.bw/week) was administered to other four groups for plumbism model over 4 weeks, of which three groups were supplemented with one of the following raw garlic juice: 1.10 (1% diet), 2.21 (2%) and 3.31 (3%) ㎎/㎏.bw/day respectively. Body weight gain rates in all garlic group significantly increased, especially in 2% garlic group that showed 9.8% net gain, as compared with only-lead treated group but lower values than control. The fecal and urinary lead excretion in all garlic groups significantly increased in a dose dependent fashion with highest value of 9.59% net gain in 3% garlic group as compared to lead treated control group. In comparison with lead treated control group, all garlic groups showed significantly increased hemoglobin contents, hematocrit values (Hct), red blood cell (RBC) count, mean corpuscular volume (MCV), and δ-amino levulinic acid dehydratase (δ-ALAD) activities. The values of 2% and 3% garlic groups remarkably increased while no significant difference between the values of 2% and 3% garlic groups was observed. The ALT activities, blood urea nitrogen (BUN) and creatinine (CR) in all garlic groups significantly decreased as compared with lead-treated control group. The values of 2% garlic group were the lowest and significantly different from the values of 1% and 3% garlic groups. The results showed that 2%-3% garlic juice in diet had obviously antidotal effects in lead-poisoned rats by promoting lead excretion. However, mega dose garlic such as in 3% garlic group might have some adverse effects on hepatic and renal functions in rats. In conclusion, the dietary habit to take ordinary garlic sauce in appropriate amount, may be helpful for preventing lead or other heavy metal intoxication.

  • In this study, black garlic was produced by aging under high temperature $(70^{\circ}C)$ and high humidity (90% RH) conditions. Then, the physiological activity and antioxidative effects of its extract were compared to those of normal garlic extract. The black garlic extract had a 2.5-fold higher total polyphenol content than that of the normal garlic extract, showing levels of 10.0 mg/g and 3.7 mg/g, respectively. At the $1,000{\mu}g/mL$ concentration, the black garlic and normal garlic extracts had electron donating abilities of 101.9% and 12.9%, respectively. For their nitritescavenging effects, the normal garlic extract showed slightly higher scavenging activity than the black garlic extract at the 5 mg/mL concentration; whereas the black garlic extract had a slightly higher effect at concentrations above 20 mg/mL. In terms of their superoxide dismutase activities, the black garlic extract showed a 10-fold higher activity as compared to the normal garlic extract at the 20 mg/mL concentration. Furthermore, at 50 mg/mL, the angiotensin converting enzyme inhibitory effects of the normal garlic and black garlic extracts were approximately 52.7% and 88.8%, respectively. These results indicate that the antioxidant activity and ACE inhibitory effects of the black garlic extract were greater than those of the normal garlic extract.
