“…Five Polish potato varieties (Hermes, Saturna, Rosalind, Raja, and Courage) had 9.51, 9.94, 9.73, 10.30, and 9.35 g/100 g DM, respectively (Gumul and others ). According to Ncobela and others (), potato peel contains 61.0 to 125 g/kg crude fiber in the DM. Potato solid waste was also reported as a good source of fiber (27 to 35 g/100 g) (Afifi ; Sharoba and others ).…”

Fruits and vegetables are the most utilized commodities among all horticultural crops. They are consumed raw, minimally processed, as well as processed, due to their nutrients and health-promoting compounds. With the growing population and changing diet habits, the production and processing of horticultural crops, especially fruits and vegetables, have increased very significantly to fulfill the increasing demands. Significant losses and waste in the fresh and processing industries are becoming a serious nutritional, economical, and environmental problem. For example, the United Nations Food and Agriculture Organization (FAO) has estimated that losses and waste in fruits and vegetables are the highest among all types of foods, and may reach up to 60%. The processing operations of fruits and vegetables produce significant wastes of by-products, which constitute about 25% to 30% of a whole commodity group. The waste is composed mainly of seed, skin, rind, and pomace, containing good sources of potentially valuable bioactive compounds, such as carotenoids, polyphenols, dietary fibers, vitamins, enzymes, and oils, among others. These phytochemicals can be utilized in different industries including the food industry, for the development of functional or enriched foods, the health industry for medicines and pharmaceuticals, and the textile industry, among others. The use of waste for the production of various crucial bioactive components is an important step toward sustainable development. This review describes the types and nature of the waste that originates from fruits and vegetables, the bioactive components in the waste, their extraction techniques, and the potential utilization of the obtained bioactive compounds.

“…A cheap and appropriate preservation strategy to enable the utilisation of the potato hash would be ensiling, but it comes with challenges. The high moisture content present in potato hash does not bode well for ensiling, but good quality silage can still be obtained if the potato hash can be mixed with absorbents to raise the dry matter (DM) content [5,6]. The addition of an absorbent however results in a composite product which needs to be investigated with regard to impact on nutrient digestion, rate of passage and physicochemical properties of the digesta to fully understand its value to Windsnyer pigs.…”

“…Sweet potato tubers are suited to direct human consumption; however, smallholder farmers face difficulties to control the attractiveness (visual aspect and colour) demanded by local markets. Sweet potato stalks and leaves are particularly suited for animal feed in smallholder pig production [115], due to its high-protein content. The dry-milled or starch fractions of landrace maize and sweet potato can be used to produce flour and a range of industrialised food.…”

Understanding the Implications of Alternative Bioenergy Crops to Support Smallholder Farmers in Brazil

Smallholders constitute more than three quarters of the world’s farmers, and despite their numbers, they commonly lack opportunities to advance their development status. Bioenergy production and consumption can help sustain smallholders’ energy needs and generate employment and income, but it also raises concerns over social justice and equity, especially where crops used for bioenergy could also be used for food. This perspective paper is grounded in a literature review related to three different crops in Brazil: sugarcane, landrace maize and sweet potato. It seeks to determine if these crops offer the potential to support smallholder farmers’ development in a more equitable way, focusing on opportunities for their use in bioenergy. We review the literature to identify policies shaping the smallholder development context in relation to these crops, assessing whose knowledge informs policy and institutional decision making, and highlighting the policy attention afforded to the different crops from different sectors. We further evaluate the literature on each crop in relation to water use and calorific value (i.e., food and energy). Our review indicates that while sugarcane has received the most policy and institutional attention, its development is largely anchored in research and development investments that support large-scale commercial farms and agri-businesses. Smallholders have not benefited or had the opportunity to engage in relevant policy decision making for sugarcane cultivation. At the same time, smallholders hold valuable untapped knowledge on the cultivation of sweet potato and landrace maize, both of which have the potential to generate development opportunities for smallholders. Our review suggests that the environmental impact of landrace maize and sweet potato in terms of water use is significantly lower than sugarcane, while they can generate more calories for energy or food consumption and offer diversification opportunities. Despite that these alternative crops offer considerable untapped potential to support rural development, more research is still needed to harness these benefits. Changes are needed to address inequities in policies, institutions and the types of knowledge informing decision making. Such changes need to afford smallholder farmers greater recognition and participation in decision making, so that the distribution of benefits from the three study crops can reach them to support their development better.
