瑜伽師地論略纂 8.37

8.37

論噉甞中，何故餅等為噉，乳等為甞？答不可咀嚼名甞，可咀嚼名噉。以餅等實食不可𭊹嗍名噉，可𭊹嗍名甞。或且汎爾言噉甞無異，須世俗情而建立故。

Regarding chewing and tasting in the treatise, why are cakes and the like considered "chewing," while milk and the like are considered "tasting"? The answer: that which cannot be masticated is called "tasting"; that which can be masticated is called "chewing." Because solid food such as cakes cannot be sipped and sucked, it is called "chewing"; that which can be sipped and sucked is called "tasting." Or it may generally be said that chewing and tasting have no difference, but are established according to worldly convention.
