Cheese whey (CW) is the yellow-green liquid main by-product from cheese manufacturing. Historically, it has been recognized as a major environmental pollutant. Nowadays, it represents a source of high-quality nutrients, such as lactose. Enzymatic bioprocesses, chemical synthetic reactions and microbial bioprocesses use lactose as substrate to obtain relevant derivatives such as lactitol, lactulose, lactosucrose, sialyllactose, kefiran and galacto-oligosaccharides. These lactose derivatives stimulate the growth of indigenous bifidobacteria and lactobacilli improving the intestinal motility, enhancing immunity and promoting the synthesis of vitamins. Also, they have versatile applications in pharmaceutical, biotechnological and food industries. Therefore, this book chapter shows the state of the art focusing on recent uses of CW lactose to produce value-added functional compounds and discusses new insights associated with their human health-promoting effects and well-being.

The purpose of this chapter is to provide information on wool production from Mexico in a period from 1980 to 2019, addressing some of the problems faced by the wool market over time. An analysis of variables such as national production of wool, cost of kg of wool, import and export of wool was performed with the aim of having a complete picture of the situation in Mexico. Also, the production of Mexico was compared with that of other countries that occupy the first places in wool production and quality, to have a starting point and propose improvement scenarios for the production of Mexican wool production. Overall, wool production in Mexico cannot cover the national demand, having to resort to the import of this product. The use of native resources of the region, such as the “Chiapas sheep breed” allows the development and maintenance of traditional ancestral culture, such as the Tzotzil, and the manufacture of handicrafts typical of each of the regions of Mexico. However, the management of long-term programs through the inclusion of dual-purpose breeds, wool, and meat can be a viable alternative for the development of the wool industry in Mexico.
