솎은 과실의 일반성분은 완숙과실 보다 조단백질, 조지방, 회분함량이 높았으나 탄수화물 함량은 낮았다. 무기물 함량은 Ca> Mg＞ P＞ Na＞ K＞ B 순이었다. 중금속 중 As, Cd, Cr, Hg는 검출되지 않았고 Ge, Mo, Ni, Pb 등은 극 미량이었다. 유기산은 tartaric acid, citric acid, malic acid, succinic acid 등이 검출되었으나 솎은 배는 citric acid가 검출되지 않았다. 유리당은
Thinned fruits, apple, pear and peach were investigated into chemical components and physiological activities. On proximate compositions, crude protein, crude fat and ash of thinned fruits were higher than those of ripe fruits, showing lower carbohydrate in thinned fruits. The contents of inorganic substance were Ca, Mg, P, Na, K and B in order. On heavy metals, As, Cd, Cr and Hg were not detected and Ge, Mo, Ni and Pb were trace. Organic acid in thinned apple and peach were detected as tartaric acid, citric acid, malic acid and succinic acid, but thinned pear did not contain citric acid. Free sugars in thinned pear and peach were composed of glucose, fructose and sucrose but sucrose was not detected in thinned apple. Contents of insoluble dietary fiber in thinned fruits were higher than soluble dietary fiber. The thinned apple extracts showed high antioxidant activity. Nitrite scavenging activity of thinned apple and pear extracts were 71∼80 e/o and 61∼63% at pH 1.2, respectively. Tyrosinase inhibitory activity of thinned pear extracts was 61.0∼89.4 ％, however peach extinct showed no activity.
