Rabbit meat could play an important role in health, the rural economy, and sustainable development. Rabbit meat has excellent nutritional features, such as high protein content, low-fat content, and a high percentage of unsaturated fatty acids, low cholesterol and sodium levels. In addition, rabbit meat production contributes to maintaining economic activities in rural marginal areas. However, the consumption of rabbit meat is still limited due to several factors such as the higher cost of commercial food that is slowing down rabbits’ breeding. Socio-demographic characteristics, attitudes, and nationality of consumers influence the demand and consumption of rabbit meat. The social and economic changes of the past years are leading to an increased interest in rabbit meat products with convenience characteristics. Consumers are also increasingly paying attention to animal husbandry methods for health concerns and ethical reasons. This paper presents an overview of rabbit meat focusing on production, nutritional composition, consumers’ preferences, and marketing. The review proposes strategies that, coupled with information campaigns could improve consumers’ knowledge of the positive characteristics of rabbit meat, which would contribute to the market development.

In this study, fresh Lentinula edodes was dehydrated using freeze-drying (FD), hot-air drying (HAD), and natural drying (ND), and the volatile and non-volatile flavor compounds were analyzed. The drying process changed the contents of eight-carbon compounds and resulted in a weaker “mushroom flavor” for dried L. edodes. HAD mushrooms had higher levels of cyclic sulfur compounds (56.55 μg/g) and showed a stronger typical shiitake mushroom aroma than those of fresh (7.24 μg/g), ND (0.04 μg/g), and FD mushrooms (3.90 μg/g). The levels of 5′-nucleotide increased, whereas the levels of organic acids and free amino acids decreased after the drying process. The dried L. edodes treated with FD had the lowest levels of total free amino acids (29.13 mg/g). However, it had the highest levels of umami taste amino acids (3.97 mg/g), bitter taste amino acids (6.28 mg/g) and equivalent umami concentration (EUC) value (29.88 g monosodium glutamate (MSG) per 100 g). The results indicated that FD was an effective drying method to produce umami flavor in dried mushrooms. Meanwhile, HAD can be used to produce a typical shiitake mushroom aroma. Our results provide a theoretical basis to manufacture L. edodes products with a desirable flavor for daily cuisine or in a processed form.
