8. Bromeliaceae.—Pineapple family.
57. ANANASSA.—PINEAPPLE. The fruit of Ananas'sa sati'va Schultz. The fresh juice contains the digestive ferment, bromelin, which is a powerful and rapid digestant of albumen, both animal and vegetable, acting in the presence of either acid or alkaline carbonates, but most energetically in neutral solutions. It is more nearly related to trypsin than to pepsin.
