CONSTITUTION:Trypsin is added to hydrolyze an aqueous solution of casein and the pH of the resultant hydrolyzate solution is regulated to 4.0-5.0. The formed precipitate is then removed and the obtained supernatant is further regulated to pH<4.0. The formed precipitate is then removed and the prepared supernatant is subsequently regulated to pH >=5.0. Thereby, the objective mixture having the following physico-chemical properties is obtained: 2000-5000 molecular weight distribution; <=25.0 ratio of number of molecules of nitrogen/ phosphorus; having preventing effects on calcium insolubilization; >=95% transmittance at 800nm of a 10(wt./vol.)% aqueous solution; without causing precipitation and clouding by heating a 10(wt./vol.)% aqueous solution at >=80 deg.C temperature and without causing precipitation and clouding even by dissolving thereof in an acidic solution at pH <=5.0.

2. Description of the Related Art In recent years, the calcium intake of Japanese people has tended to be insufficient as compared with the required amount. Especially, the insufficient calcium intake of school children, pregnant women, and middle-aged women has become a serious problem. .. Calcium deficiency causes various diseases,
In particular, bone fractures caused by osteoporosis have become a major social problem. Although osteoporosis is caused by a low intake of calcium, it is said that it is also caused by a low absorption rate of ingested calcium in the digestive tract. The pH in the small intestine where calcium is absorbed is neutral to weakly alkaline, and calcium is easily precipitated or insolubilized.

(2) Test method 1 ml of calcium chloride solution and 1 ml of sample solution were placed in a test tube, 2 ml of phosphate buffer was added, and the mixture was kept at 37 ° C. for 2 hours. Then, it was filtered with a filter (pore size 0.45 μm), 0.1 ml of dilute hydrochloric acid solution was added to 0.5 ml of the filtrate, and the amount of calcium in the filtrate was measured with a Hiranuma Ca-Mg counter (manufactured by Hiranuma Sangyo Co., Ltd.). The solubilization rate of calcium was tested by calculating the percentage of the difference between the amount of calcium in the initially added calcium chloride solution and the amount of calcium in the filtrate, relative to the amount of calcium in the initially added calcium chloride solution.

(3) Test Results The test results are shown in Table 1. As is clear from Table 1, sample 1 (acid-resistant casein phosphopeptide mixture of the present invention) was subjected to sample 2 (conventional product produced by a typical conventional method) and sample 3 (precipitation once at a pH of less than 4.0). A significantly higher calcium insolubilization-preventing effect (higher solubilization rate) was observed at a lower concentration as compared with the removed sample). Therefore, it was revealed that the acid-resistant casein phosphopeptide mixture of the present invention has an extremely excellent effect of preventing calcium insolubilization. Although the starting materials and the manufacturing method were changed and other conventional products were tested as controls, almost the same results were obtained.
