Abstract: Animal based milk and its products have been the most important part of dairy consumption, but then demand has steadily outpaced the consumption since the mid-20th century especially in the last decade. This shift has coincided with a growing consumer preference for vegetative origin milk alternatives, which increasingly come from soy, legumes, nuts, seeds, and grains. This review is focused on the potential of plant-based milk alternatives, including soymilk, chickpea milk, kidney bean milk and cowpea milk as sustainable, nutritious, and functional substitutes for traditional dairy milk. Recent findings highlight advancements in processing methods such as heat treatment, fermentation, and germination, which mitigate anti-nutritional factors, enhance flavor profiles, and improving sensory and nutritional qualities. Emerging legume-based options, beyond the widely consumed soymilk, appear promising to for diversify the-se alternative plant-based milk resources owing to their superior protein quality, bioactive compounds, and environmental benefits. This review also underscores the sustainability of legumes, highlighting their contributions to soil health, nitrogen fixation living little carbon footprints compared to dairy milk and its products. This review affirms that legume-based milk alternatives offer a viable, sustainable solution to global challenges in food and nutrition security and environmental health apart from providing healthier options for lactose-intolerant and saturated fat consumption conscious consumers.

Abstract: The orange-fleshed sweet potato (OFSP) is a nutrient-rich crop with high β-carotene content, which helps prevent vitamin A deficiency (VAD). However, its semi-perishability requires proper processing to preserve its nutritional and sensory properties. This study assessed the effects of sun and solar drying on the proximate composition, β-carotene, vitamin C, mineral content, and sensory attributes of OFSP porridge and Ugali (stiff porridge) consumed in the Lake zone of Tanzania. Three variety of OFSP; Ejumla, Jewel, and Carrot Dar, were subjected to solar or sun-drying and subsequently processed into flour. The resulting flours were used to produce porridge and Ugali (stiff porridge). Conventional techniques were employed to evaluate the proximate composition, β-carotene, vitamin C, and micronutrient content of porridge and Ugali (stiff porridge). Additionally, sensory analysis was performed to assess the level of acceptability of the items' sensory qualities. There was a significant difference in moisture content, crude protein, and crude fat between porridge and Ugali (stiff porridge) for all three varieties of OFSP (p<0.05). Moreover, solar-dried products had higher retention of β-carotene (28.79 mg/100 g) and vitamin C (3.29-10.45 mg/100 g). Sun-dried products had lower mineral content than solar-dried products. There was also a significant difference (p<0.05) between solar and sun-dried products in all tested essential minerals. The nutrients analyzed were more concentrated in stiff porridge than in regular porridge, such as calcium (21.65mg/100g), potassium (90.70mg/100g), Sodium (169.98mg/100g), magnesium (13.26mg/100g) and zinc (0.51mg/100g). Solar-dried items had the highest acceptability scores (3.0–3.9) compared to sun-dried products, with Ejumla being the most preferred. The findings depict that solar drying preserves OFSP-based food's nutritional and sensory quality better. Solar-dried OFSP may reduce vitamin A deficiency (VAD) and improve nutritional security in Tanzania.
