abstract = "Simple Summary Introducing alternatives to surgical castration of pigs bring welfare and economical benefits, but also reveal several quality-related issues. Most important is the presence of boar taint, but also includes low quantity and quality of fat, meat texture and color deviations in addition to inferior water binding properties, most of them negatively influencing meat product characteristics. The present paper highlights the important differences between the conventionally used surgical castrates and the most likely introduced alternatives: entire males and immunocastrates. Based on the review of the available research, the possible reasons for quality alterations are elaborated according to the type of meat product and recommendations for improving product quality or preventing boar taint perception are given. Due to the strong public initiative in Europe and increased regulator focus to mitigate pain, surgical castration of pigs is being gradually abandoned, while the importance of other sex categories like entire males (EM) and immunocastrates (IC) increases. Although beneficial for animal welfare and economics, their use also brings forward several quality problems. Besides the occurrence of boar taint in EM, these include excessive carcass leanness, softer fat, meat color and pH deviations, inferior water holding capacity and increased meat toughness. In this paper, the raw material differences between the male sex categories and their influence on product quality are reviewed, and possible solutions are presented. Using EM for dried or thermally processed products may result in lower processing yields and inferior sensory quality, which may partially be prevented by applying specific processing adaptations. Immunocastration is a viable solution, especially when prolonging the vaccination to slaughter interval. Low to medium levels of boar taint can be effectively managed in most of the meat products, applying procedures like cooking, microbial inoculation or masking (by spices and especially smoking), while highly tainted material can be valorized only by combining various methods and/or with dilution of the tainted meat.",
