khi phia (เพี้ย / ขี้เพี้ย / น้ำเพี้ย)
seasoning / seasoning-khi-phia
キーピア
Partially digested plant matter and digestive fluid from the small intestine of cattle or buffalo (also referred to as เพี้ย, ขี้เพี้ย, or, in liquid/broth form, น้ำเพี้ย), added as a bittering seasoning to larb, offal soups and other Northern Thai and Isan dishes; the portion nearest the bile duct opening (เพี้ยหัวดี) is considered the more liquid, less fibrous, better-quality grade.

Reading the bitterness
เพี้ย (phia), ขี้เพี้ย (khi phia), and น้ำเพี้ย (nam phia), which refers to the liquid form, are words for partly digested contents remaining in the part of the small intestine of cattle or buffalo between the openings of the bile and pancreatic ducts. The introduction to a nutrition paper distinguishes the part nearest the bile duct as a part considered 「良質」 (in translation: "good quality"), while a food-culture article describes it as liquid, with little fibrous residue and a mellow bitterness. The nature of the material itself, intestinal contents from slaughtered livestock, connects this entry with bitterness from the outset.
A proximate-composition analysis of cattle intestinal contents collected at slaughterhouses and butcher shops in Sakon Nakhon Province on 3 occasions—2021-8, 2021-12, and 2022-4—reported mean values of 87.02±0.10% moisture, 1.75±0.06% crude protein, 0.80±0.13% crude fat, 6.35±0.15% crude carbohydrate, 2.27±0.08% crude fiber, and 1.81±0.22% crude ash. Only cattle were studied; the same measurements were not made for khi phia from buffalo or pigs.
The paper's introduction says khi phia is used to add bitterness to raw-meat larb and koi, chili dip jaew, and meat stew om. A food-culture article adds that it is used in soi chu, a dish of sliced raw meat, and a bitter chili dip, and depicts it as routine for northeastern Thai restaurants to ask guests whether they want bitterness added. An individually posted recipe says nam phia may be added to a bitter offal soup to taste. A record of water-buffalo larb among the Thai Lue in neighboring Laos also gives a procedure using the same ingredient, but does not itself explicitly describe the taste as bitter.
The section farther along the intestine is described as watery, with more residue and a stronger smell, so preliminary boiling before cooking is recommended, while some cooks are also described as using it raw without that step. A record of larb khom in Phrae Province lists bile as an alternative bittering ingredient to intestinal contents, and a northeastern Thai food-culture article likewise treats the two together as sources of mellow bitterness. Most of these descriptions, however, are secondhand citations in article introductions or food-media pieces, not the authors' own primary surveys, and there is no numerical measure of bitterness intensity.

Composition and content (2)
Scope: Food culture of northeastern Thailand (Isan); a description in the introduction to a nutrition and food-hygiene paper.
Note: The paper's introduction cites a definition from earlier secondary sources (แสงอรุณ กนกพงศ์ชัย 2546; วิศิษฏ์ภูมิ สุขสมบัติ 2546); it is not the authors' own field survey.
