豆乳的生产

一、引言制作豆乳的主要原料是黄豆,丹麦专家称黄豆是中国的乳牛。豆腐、豆乳和酱油等豆制品是中国发明的,到目前为止,中国已有三千多年的生产历史,后来传到了日本、朝鲜、东南亚、美国、丹麦和欧洲,过去的十年又传到了非洲。豆乳的营养价值被越来越多的人所认识。因此,消费量也越来越     

豆乳浆生产中提高豆蛋白质抽出率的研究

本文初步探讨在豆乳生产过程中,大豆预处理条件(灭酶、浸豆等)和磨碎提取条件(磨碎、过滤等)对豆蛋白抽出率的影响及不同条件下制得的豆浆(乳)的粘度变化。研究结果表明:采用160℃干热灭酶30秒钟,以40C,PH9.0—10.0的碳酸氢钠溶液浸豆,75—80C,PH7.5,1:15(豆冰)的水量(用碳酸氢钠调PH)磨豆,浆液在80C左右过滤的工艺,可获得较高的蛋白质抽出率及固形物抽出率,制得的豆乳质量较高。     

豆乳生产关键工艺技术的研究

本文提出豆乳生产的关键技术,包括三个方面,去除豆腥味：排除有害因子;提高蛋白质回收率。结论认为,脱腥 增香,对提高豆乳质量是极为重要的。     

无臭豆乳生产技术

一、前言目前,我国奶类尚不丰富,据统计,1986年全国牛奶产量为286万吨,连同其他乳类,全国乳产量只有340万吨,人均3.4kg,这与世界发达国家人均占有乳量100kg相比,差距很大。根据营养学家评定,豆奶具有与牛奶同等的营养价值(见表1),就其保健价值而言,     

豆乳的生产工艺及豆乳系列饮料开发

阐述了大豆经浸泡、磨制、分离、脱腥、灭酶、均质、灭菌等工艺处理后，成为一种营养丰富，易于人们接受的大豆系列饮品，为人们提供了大豆的一种科学方便的食用方法。     

豆乳乳酸菌饮料的生产

豆乳乳酸菌饮料,是以豆乳为主要原料,经乳酸菌发酵制成的,具有特殊风味的仿酸乳制品。本文就其豆乳的制备、发酵液的生产以及产品发酵和产品后期处理做了叙述。     

THE INFLUENCE OF THE REFRIGERATED FARM BULK MILK TANK ON THE QUALITY OF THE MILK AT THE PROCESSING DAIRY

A brief review is given of the bacteriology of bulk milk collection, with particular reference to the total bacterial content of the raw milk at different stages of collection. This is followed by a consideration of appropriate reference, routine and simplified tests and standards for the bacteriological quality control of bulk collected milk.
It is recommended that the total colony count, thermoduric count and coliaerogenes count, all at 27°C, should always be used for investigational, survey and advisory work. As these tests are too laborious, slow and expensive for the routine fortnightly grading of farm bulk tank milk supplies at creamery laboratories, a modified resazurin test at 30°C is prescribed for this purpose.     

PROFITABLE PROCESSING OF MILK BY-PRODUCTS

An attempt has been made in this paper to give a brief glimpse of the way the dairy industry in New Zealand is structured in order to maximize the return to the milk producer. The industry being co-operative, the producer of milk is also a shareholder in the dairy company to which his milk is forwarded, processed and manufactured. The paper could more properly be entitled 'The Profitable Production of Milk and Milk Products'.     

新型高阻隔包装材料在乳品包装领域的应用
