在墨西哥对用菠萝汁浓缩液(白利糖度为25、30和40)生产菠萝汁粉进行了试验。一种表面活性剂混合剂加麦芽糊精作为辅助剂加入菠萝浓缩液中,并搅拌。通过下法可获得充分的泡沫:(1)25白利糖度的浓缩液用表面活性剂(Sorbac60—Polisorbac80);(2)表面活性剂占总固形物重百分率为0.285％;(3)亲脂基与亲水基之比为6;(4)搅拌7分钟。浓缩泡沫在烤炉中脱水,然后用60、70、 Experiments were conducted in Mexico on the production of pineapple juice powder using pineapple juice concentrates (Brix 25, 30 and 40). A surfactant mixture plus maltodextrin as an adjuvant was added to the pineapple concentrate and stirred. Sufficient foam can be obtained by the following method: (1) 25 Brix concentrates with surfactant (Sorbac 60-Polisorbac 80); (2) surfactant with a total solids weight percent of 0.285%; (3) lipophilic Base and hydrophilic group ratio of 6; (4) stirring for 7 minutes. The concentrated foam is dehydrated in an oven and then treated with 60, 70,
