以微胶囊包埋率为评价指标,采用响应面法优化苦杏仁油微胶囊制备工艺;同时为验证微胶囊化对油脂氧化稳定性的促进作用,以微胶囊化前后的苦杏仁油为对象,采用烘箱加速法进行加速氧化试验,每3 d测定1次苦杏仁油和微胶囊中过氧化值、碘值、酸价、皂化值、共轭二烯烃值,并利用傅里叶红外光谱进行扫描鉴定其中的官能团。结果表明,苦杏仁油微胶囊制备的最佳工艺条件为:壁材料液比1∶16(g/mL),乳化剂添加量2.1%,芯壁比1∶85(g/mL),微胶囊平均包埋率为84.07%±0.37%,符合预测值。苦杏仁油在(60±1)℃的条件下储藏至第12天时,其过氧化值超过国标中的最低限量标准(0.25 g/100 g);而微胶囊化后的苦杏仁油在整个储藏期间各项指标的变化幅度较小,表明微胶囊化有利于提高油脂的氧化稳定性。该研究结果为开发油脂微胶囊化保存手段奠定了理论基础。 相似文献

Soybean sprouts are an important year-round vegetable in Asia. Currently, testing of soybean lines for sprout traits is labor
intensive and amount of seed required have dictated that testing generally begins after lines have been composited from a
plant row in the F4 or later generations. Sprout testing requires germination of more than 150 seeds, precise watering over several days and
movement of seedlings from water baths to growth chambers limiting the number of entries which can be evaluated. The objective
of this study was to determine if germinating fewer seeds (10, 20 or 40) on an agar medium is comparable to sprouting over
150 seeds in the traditional method for evaluating soybean genotypes for sprout traits. Sprout growth characteristics were
compared for Pungsannamulkong, a known sprout soybean, germinated on 1.0, 1.2, and 1.4% agar medium. Sprout traits 5 days
after seeding 20 or 40 seeds on a 1.4% agar medium were very similar to the traditional method. There was no advantage for
germinating soaked seeds over dry seeds on the agar medium to determine sprout characteristics. Evaluation of 20 dry seeds
on a 1.4% agar medium of eight known sprout cultivars was comparable to the traditional method for measuring sprout characteristics
for each cultivar. The agar method requires less labor, fewer seeds, no watering schedules or water baths and less growth
chamber space than the traditional method to test genotypes for sprout characteristics. This allows more lines from soybean
breeding populations in earlier generations to be evaluated. The agar method will improve the efficiency for evaluating soybean
breeding lines for sprout traits. 相似文献

Soybean sprouts, a traditional vegetable in Asia, are gaining popularity in the United States. Soybean sprout demand has been supplied by natto (a Japanese soyfood) cultivars that share some seed characteristics with sprout cultivars. However, natto seeds do not meet all requirements of sprouts and are rejected by sprout manufacturers. The objectives of this study were to evaluate important seed and sprout traits as potential selection criteria in breeding sprout soybeans and to study the storage effect on soybean sprout quality. Almost all genotypes produced thicker and longer hypocotyls and higher fresh-sprouts than ‘MFS-561’, a commercial soybean sprout variety. Hypocotyl length ranged from 13.8 to 16.2 cm. Four fungi genera Bipolaris sp., Cercospora sp., Botrytis sp. and Caethomium sp. were isolated from seeds. Cracked cotyledons and abnormal seedlings were the two main constraints affecting soybean sprout quality. Correlation coefficients among all traits indicated that percentage and weight of high- and average-quality sprouts would determine sprout yield. Acceptable yield and several traits were recommended to be used simultaneously while breeding superior sprout soybean cultivars. Good sprout varieties should produce high-quality sprouts >48%, average-quality sprouts <38%, low-quality sprouts <14%, sprout yield >5.7 g/g seed, hypocotyl thickness >1.6 cm and hypocotyl length >13 cm. One-year seed storage at room temperature reduced sprout quality. V09-3876 and V12-1939 had superior seed and sprout traits and are promising lines for further evaluation for sprout production. Seed storage over time affects seed germination and seedling vigor, and fungi on seed can cause reduced seed quality. 相似文献

Fatty acid composition and C18:2:C18:3 of soybean seed and sprout is important for soy-industries to manufacture quality products. Six soybean varieties were analyzed
by gas chromatography to determine fatty acid composition and linoleic to linolenic acid ratio (C18:2:C18:3) in seed, sprout, and their structural parts. In the case of whole seed and its structural parts, significant variation in
fatty acid composition and C18:2:C18:3 were observed between varieties except palmitic acid (C16:0), while all the parameters were significantly different for seed parts. Significant interactions of variety with seed parts
were observed for oleic acid (C18:1), C18:2 and C18:2:C18:3. The highest saturated fatty acid, C18:1 and polyunsaturated fatty acid were recorded in seed coat, cotyledon, and seed axis, respectively. The lowest C18:2:C18:3 was found in seed axis. In the case of sprout study, variety had significant effect on all the parameters observed for whole
sprout, cotyledon, root, and except C18:3 for hypocotyl. Culture days had significant effect on C16:0, C18:2 and C18:3 in whole sprouts, while only on C18:3 and C18:2:C18:3 in cotyledon. For hypocotyl, culture days had significant effect on C18:1, C18:2 and C18:2:C18:3, however, C16:0, C18:1, C18:3, and C18:2:C18:3 were significantly different in root. In sprout, days and variety interacted significantly for C16:0, C18:3 and C18:2:C18:3, and C18:1, C18:2, C18:3, and C18:2:C18:3, respectively for whole, cotyledon, and root. The significantly lowest C18:2:C18:3 (1.1) was observed in hypocotyl and root of Hwangkeumkong in 5 days. Knowledge of fatty acid composition and C18:2:C18:3 of seed, sprout, and their parts could be applicable for oil and other soy-food industries to make quality products. 相似文献

不同温度对大豆种子萌发影响的研究 总被引:7,自引:1,他引:7
通过对东农42、东农43、东农163、合丰25、绥农10号采用六种发芽温度4℃、8℃、12℃、15℃、20℃、25℃下温度对大豆种子萌发影响的研究,表明:4℃、8℃温度过低,在调查期间种子一直没有发芽。其它几个温度的发芽率以15℃为最高,12℃为最低,同前人研究发芽率随温度升高而升高不同。同一温度不同品种的发芽率、平均芽长在品种间差异显著,说明种子萌发受遗传因素影响,同一品种不同温度之间的平均芽长随温度的升高依次升高。实验的研究有利于确定大豆的田间播种温度,为适时早播,保证田间种子的发芽,出苗,成苗,及时的成熟提供依据,并为最终的高产奠定基础。 相似文献
