摘要
以凝固液的pH值及鲜胶乳的凝固效果为考核指标,研究了生物凝固液的制备工艺,第1次培养生物凝固液其清水∶菌种∶糖蜜比例为100∶0.5∶5,对鲜胶乳进行凝固后所得乳清加糖蜜继续培养生物凝固液,其乳清∶糖蜜比例为100∶5。结果表明,采用乳清制备的凝固液比用清水、菌种、糖蜜制备的凝固液其凝固效果更好,胶乳每次生物凝固所得乳清只加糖蜜重复培养生物凝固液,至少可循环利用20次以上。而温度越高,生物凝固液pH值降低越快,当pH值降至4.0以下,即可用以凝固胶乳。
The production technology of biological coagulation liquid was studied in this paper. Initially, water, bacteria and adjuvant were used to foster biological coagulation liquid with the ratio of 100/0.5/5. Then the serum from latex coagulation was added with adjuvant with the ratio of 100/5, which was used to foster biological coagulation liquid continually. The results showed that the serum with adjuvant had better coagulation effect than the initial coagulation liquid. The higher the temperature, the faster the pH value of biological coagulation liquid reduced, and it could be used to latex coagulation when the pH value was below 4.0. The serum from biologieal coagulation could be used to foster biological coagulation liquid repeatedly, 20 times at least.
