“…However, the hardness level of meat and meat products not only depends on the operating parameters of these nonthermal technologies but also depends on the type of proteins and other preparation of raw materials. Combination of nonthermal technologies with other appropriate pretreatment methods such as pretreatment using enzymes like papain, bromelain, and actinidin (Takei, Hayashi, Umene, Kobayashi, & Masunaga, 2016;Zhu, Kaur, Staincliffe, & Boland, 2018), organic acids like lactic and citric acids (Aktaş, Aksu, & Kaya, 2003), soy sauce (Kim et al, 2013), vinegar (Tänavots et al, 2018), and fruit and vegetable juices (Gök & Bor, 2016) has proved to help reduce the hardness of meat and meat products from level 1 or 2 to level 3 or 4. Therefore, it is still too early to conclude which technique would yield the best results.…”
