Discriminating the quality of local pork from crossbred pork from extensive production of ethnic minorities in mountainous northern Vietnam
Developing short food supply chains for products from local pig (Sus scrofa domesticus) breeds may offer chances for smallholders in rural areas to participate in niche markets and obtain additional income. Because the authenticity and distinctness of products are crucial for establishing marketing, this study compared selected product characteristics of pork from the Vietnamese Ban breed with pork from crossbreds, each derived at their typical market weight and from their respective extensive and semi-extensive production environment; thus resembling the combination, the products are available for customers. Traditional Ban pork could be effectively discriminated from crossbred pork through cut dimensions, exemplified by the significantly reduced loin eye area (P < 0.001), and by the significantly reduced backfat thickness (P < 0.001). Also, marbling fat was significantly decreased in local pork (P < 0.001), whereas differences in further meat quality parameters were rather weakly expressed. The significantly higher share of polyunsaturated fatty acids in loins of traditionally produced Ban pigs (P = 0.003) could possibly result in a preferred nutritional value, but lower oxidative stability of the products. This study provides novel information to improve the marketing of specialty pork in Vietnam and comparable situations in the Southeast Asian Massif.
