Analyses of Pungency-Related Factors of Field and Rice Paddy Garlic

Abstract

The purpose of this study is to evaluate pungency-related factors of field garlic (FG) and rice paddy garlic (RG) from Youncheon province. Allicin, alliin, and S-allyl-L-cysteine (SAC) contents were analyzed by HPLC. In addition, activities of alliinase, GTPase (γ-glutamyltranspeptidase), and pyruvate content of garlic were measured. The moisture content of RG (65.86%) was higher than that of FG (63.34%). However, crude lipid, crude protein, crude ash, and carbohydrate contents of RG were lower than those of FG. The alliin contents of FG and RG were 8.97 and 8.22 mg/g, respectively. The allicin content of FG (2.83 mg/g) was higher than that of RG (2.22 mg/g). Further, SAC content of FG (1.74 mg/g) was higher than that of RG (0.104 mg/g). Alliinase activities of FG and RG were similar, whereas the GTPase activity of FG was higher than that of RG. These results show that the stronger pungency of FG is due to the higher amount of alliin and SAC as well as the higher activity of GTPase compared to RG.

“…Similarly, the levels of both alliin and glucose were the highest in NG, though the alliin content did not show a significant difference between the samples. Notably, the contents of alliin and allicin, compounds associated with the pungency of garlic, differ with the cultivation area and garlic variety [ 21 , 22 ].…”

“…마늘 주산지인 의성과 예천에서도 토양의 화학적 특성 에 따라 마늘의 지상부 생장과 인경 발달이 달라졌으며, 논토양보다는 밭토양에서 생육이 더 좋고 품질이 우수한 것으로 보고 된 바 있다 (Kim et al, 2000). 그리고 밭토양에서 재배된 마늘은 수분 함량이 낮고, 조회분, 조지방, 조단백, 탄수화물 함량이 높을 뿐만 아니라 allicin 함량도 더 높다 (Oh et al, 2012). 인경의 생장도 산지별로 달라서 합천산과 남해산이 무안산, 함평산 과 제주산보다 월등히 좋을 뿐만 아니라 향기성분의 총 함량도 합천산과 남해산이 높고, 특히 남해산 마늘은 항균활성도 높은 것으로 보고된 바 있다 (Shin et al, 2011).…”
