中文摘要: 在糙米催芽过程中进行钙营养强化,并在催芽中期采取负压辅助处理富钙,研究不同浓度CaCl2溶液(100、150、200 mg/L)浸泡催芽和不同强度负压(-0.06、-0.08、-0.10 MPa)处理对发芽糙米中钙含量的影响,以及负压辅助钙营养强化对糙米在发芽过程中产生γ-氨基丁酸(gamma-aminobutyric acid,GABA)的影响。结果表明,营养强化处理最佳条件为CaCl2浸泡液浓度150 mg/L、负压处理强度-0.08 MPa、负压处理时间4 h。在此条件下得到发芽糙米中钙含量最高可达523 mg/kg,GABA含量可达89.65 mg/100 g。

Abstract:Calcium was enriched by negative pressure treatment at the middle germination stage of brown rice.The effects of CaCl2solution(100,150,200 mg/L)soaking and negative pressure treatments(-0.06,-0.08,-0.10 MPa)on calcium content in germinated brown rice were studied.Further,the effect of negative pressureassisted calcium enrichment on the content of gamma-aminobutyric acid(GABA)in germinated brown rice was studied.The optimal conditions for calcium enrichment were obtained as follows:CaCl2concentration of 150 mg/L and negative pressure treatment at-0.08 MPa for 4 h.Under these conditions,the content of calcium and GABA in germinated brown rice reached 523 mg/kg and 89.65 mg/100 g,respectively.
