'''Meat floss''', also known as '''''yuk sung''''' or '''''rousong''''' ({{zh|t=肉鬆|j=juk6 sung1|p =ròusōng}} ; Mandarin Chinese: {{IPAc-cmn|r|ou|4|s|ong|1}}), is a dried meat product of Chinese origin, with a light and fluffy texture similar to coarse cotton.<ref name="grigson">{{citation|title=World Atlas of Food |first=Jane |last=Grigson|publisher=Bookthrift Company |date=January 1985 |isbn=978-0-671-07211-7}}</ref><ref name=":1">{{Cite book |last1=Dikeman |first1=Michael |title=Encyclopedia of Meat Sciences Volume 1 |last2=Devine |first2=Carrick |date=2014 |publisher=Elsevier/Academic Press |isbn=978-0-12-384734-8 |edition=2nd |location=Amsterdam |pages=524}}</ref> It is more commonly known as '''''bak hu''''' (Hokkien: 肉拊, Pe̍h-ōe-jī: bah-hú) in Hokkien-influenced regions, such as Southeast Asia and Taiwan.<ref name="chimbridge">{{Cite encyclopedia |title=Chimbridge Singlish Dictionary of Singlish & Singaporean Terminology |url=https://singlishdict.app/?q=bak%20hu}}</ref> Meat floss is golden in color with a distinctive flavor and sweet taste that is somewhat comparable to beef jerky.<ref name=":1" />

==Production and styles== Meat floss is made by stewing lean meat finely cut along the grain (pork, chicken or beef though other meats may be used) in a broth until the meat is very tender and individual muscle fibers can be teased apart.<ref name=":0">{{Cite book |last=Hui |first=Y. H. |url=https://www.google.com.hk/books/edition/Meat_Science_and_Applications/651Zv5hUzyIC?hl=en&gbpv=1&dq=meat+floss&pg=PA415&printsec=frontcover |title=Meat Science and Applications |last2=Nip |first2=Wai-Kit |last3=Rogers |first3=Robert |date=2001-07-27 |publisher=CRC Press |isbn=978-0-203-90808-2 |language=en|pages=415}}</ref> This happens when the water-insoluble collagen that holds the muscle fibers of the meat together has been converted into water-soluble gelatine.<ref>Vickie Vaclavik, Elizabeth W. Christian. [https://books.google.com/books?id=DzMhwchiTMMC&pg=PA169 ''Essentials of Food Science'']. Springer, 2003, p. 169.</ref> The meat is then separated from the broth and shredded into fibrous strips. It is then added back into the broth which is enriched with soy sauce, sugar, fennel, ginger, rice wine or other ingredients.<ref name=":1" /> The mixture is then cooked at low heat and stirred continuously until the floss is dried.<ref name=":0" />

There are different regional styles of meat floss, which differ in whether oil is added during the last process of production. Jiangsu style ''rousong'' is dry-cooked and the product is slightly chewy, while Fujian style ''bak hu'' is fried with oil and the product is mildly crispy. {{convert|5|kg|lb|0|spell=In}} of meat will usually yield about {{convert|1|kg|spell=in}} of floss.<ref>Melia, Ken (2017). ''Review of Meat Floss – Identifying opportunities for Australian Red Meat''. North Sydney: Meat and Livestock Australia Limited</ref>

Taiwanese pork floss is made by cutting pork along the muscle fibers then boiling it for around 80 minutes to reduce moisture and soften collagen.<ref name=":0" /> The meat is then pressed into a paddle to loosen fibers, then transferred to a gas-fired frypan with mechanical scrapers to aid in drying and reducing the meat into long fibers.<ref name=":0" /> Sucrose, dehydrated starch and salt is then added at a specific time and ratio to enhance flavor and texture without hindering moisture removal. Once the desired consistency and dryness is obtained, the floss is stored briefly at room temperature and reheated in the scraping-frypan.<ref name=":0" />

==Variations== {{Chinese cuisine}} Fish can also be made into floss (魚鬆; ''yú sōng''), though initial stewing is not required due to the low collagen and elastin content of fish meat. Rabbit and duck floss can also be found in China.<ref>Zhou, Zhen (2017).

In Muslim-majority Indonesia and Malaysia, beef or chicken floss is the most popular variant, commonly called ''abon'' in Indonesian and ''serunding'' (also spelled ''serondeng'') in Malay. In Malaysia, ''serunding'' is often served during Ramadan and Eid.<ref>Thestar.com.

In Nigeria, beef, goat or other meats are processed into a similar meat floss called dambu nama.

==Health effects== A study has demonstrated a positive correlation between increased processing temperatures of meat floss and increased formation of heterocyclic aromatic amines (HAAs) within the meat. Up to seven different HAAs were found when meat floss was processed at {{Convert|150|C}}.<ref>Liao, Guozhou (April 2009).
