凝固型杏鲍菇酸奶的研制 总被引:1,自引:0,他引:1
以杏鲍菇子实体、鲜牛乳为主要原料,以感官评分为评价指标,采用单因素和正交试验确定并优化了凝固型杏鲍菇酸奶的加工工艺和配方。凝固型杏鲍菇酸奶由杏鲍菇浆和牛奶按比例混合,并加入适量白砂糖、增稠剂、甜味剂,经均质、杀菌、冷却后添加混合乳酸菌发酵剂,于42℃发酵3 h,4-6℃冷藏后熟而制得;试验结果表明,最优配方为杏鲍菇浆与鲜牛奶的配比1∶6,添加蔗糖3%,安赛蜜0.15‰,增稠剂0.06%(海藻酸丙二醇酯∶果胶=4∶2),采用保加利亚乳杆菌与嗜热链球菌为发酵剂(1∶1.5),接种量为2.5%。终产品风味良好,具有广泛的市场应用前景。 相似文献

The flavonoid compounds present in almond (Prunus amygdalus, Rosaceae), Jara (Cistus sp Cistaceae), Echium sp (Boraginaceae) and Chrysanthemum sp (Compositae) bee pollens have been studied by TLC, 2D PC and HPLC techniques. These bee pollens show characteristic flavonoid patterns which allow their use as biochemical markers of their plant origin. In addition, the flavonoid patterns of natural almond and ?Jara’? pollens have been shown to be identical to those of the corresponding bee pollens confirming their use as chemical markers. The flavonoid aglycones obtained by acid hydrolysis of pollen flavonoids are also useful for identification purposes. Almond bee pollen contains 8-methoxykaempferol, kaempferol and quercetin 3-glycosides, ?Jara’? bee pollen produces quercetin and isorhamnetin 3-glycosides and trace amounts of myricetin and kaempferol 3-glycosides, Echium bee pollen contains mostly kaempferol 3-glycosides and traces of quercetin 3-glycosides, and Chrysanthemum contains kaempferol, apigenin, and quercetin 3-glycosides. The major compound in almond pollen, namely 8-methoxykaempferol 3-glycoside, was not detected in the related apple, pear, cherry and plum pollens. 相似文献

Triggered by the development of lactic acid bacteria (LAB) during the production of Scotch whisky, this study examined the influence of yeast and LAB inoculation on whisky flavor. Four new spirits were produced using the same process. LAB were added as a form of a Greek yogurt's live culture. In each category (barley and rye), one sample was fermented with Greek yogurt while the other was fermented without it. The spirits were matured and analyzed at five different points. Results from gas chromatography-mass spectrometry (GC-MS) analysis showed basic volatile compounds, along with some important extra compounds with yogurt culture. The most obvious differences were observed in the concentration of butanoic acid, a characteristic acid in spirits undergoing lactic acid fermentation: to identify esters such as ethyl butanoate, ethyl isobutanoate, isoamyl butanoate, and 2-phenylethyl butanoate, they are not typical compounds in whisky. 相似文献
