“…Central American countries are considered as the center of SP origin, but recent times they are extensively cultivated in the tropical, in the subtropical zone, and in few temperate locations with divergent agroclimatic conditions (Chandrasekara & Josheph Kumar, ). The roots of SP plants are primary storage organs and act as sinks to photosynthetic products, and it resulted in the deposition of different micro (phytochemicals)‐ and macro (carbohydrates)nutrients (Lemoine et al, ).…”

A wide variety of the roots and tubers plays a major role in human diet, animal feed, and industrial raw materials. Sweet potatoes (SPs) play an immense role in human diet and considered as second staple food in developed and underdeveloped countries. Moreover, SP production and management need low inputs compared to the other staple crops. The color of SP flesh varied from white, yellow, purple, and orange. Scientific studies reported the diversity in SP flesh color and connection with nutritional and sensory acceptability. Among all, orange‐fleshed sweet potato (OFSP) has been attracting food technologists and nutritionists due to its high content of carotenoids and pleasant sensory characteristics with color. Researchers reported the encouraging health effects of OFSP intervention into the staple food currently practicing in countries such as Uganda, Mozambique, Kenya, and Nigeria. Scientific reviews on the OFSP nutritional composition and role in vitamin A management (VAM) are hardly available in the published literature. So, this review is conducted to address the detailed nutritional composition (proximate, mineral, carotenoids, vitamins, phenolic acids, and antioxidant properties), role in vitamin A deficiency (VAD) management, and different food products that can be made from OFSP.

“…The origin of sweet potato is Central America, but at present it is widely cultivated in the tropics and subtropics, and even in some temperate areas at different ecological regions (Chandrasekara and Kumar, 2016). In Europe, where the total production of sweet potato accounted 45.901 t in 2014, the biggest producers are Portugal (22.591 t), Spain (13.550 t), Italy (6723 t) and Greece (3038 t) (FAOSTAT, 2017).…”

“…Besides acting as antioxidants, phenolic compounds and carotenoids also provide sweet potatoes with their distinctive flesh/skin colours (cream, deep yellow, orange, purple) (Ray et al, 2012). Contribution of sweet potato towards health is acknowledged due to high nutrient content and its anti-carcinogenic and cardiovascular disease preventing properties (Chandrasekara and Kumar, 2016;Jung et al, 2011). In recent years, several reports have indicated that the phytochemicals from sweet potatoes displayed antioxidative or radical-scavenging activity with health-promoting functions (Bovell-Benjamin, 2007;Teow et al, 2007;Rumbaoa et al, 2009).…”

Genetic differentiation of Slovenian sweet potato varieties (Ipomoea batatas) and effect of different growing media on their agronomic and nutritional traits

et al. 2017

The objectives of the present study were firstly to analyse the genetic relatedness among three Slovenian sweet potato varieties; and secondly to assess the effects of different growing media on selected agronomic and nutritional traits of these varieties. Tubers of three varieties (Lučka, Janja, Martina) with different skin/flesh colour were produced in planters under glasshouse conditions in five different growing media (perlite, peat, expanded clay, vermiculite, garden soil) from prior raised seedlings. Genetic analysis was performed using a set of eight single sequence repeats markers. According to Nei's genetic distance and pairwise population Fst analysis, the most related varieties are Janja and Martina; in contrast, Lučka and Martina show the weakest genetic relationships. The following agronomic traits were evaluated: vine length, thickness of vine-base, number of branches, weight of above ground part, number of leaves plant -1 , number of tubers plant -1 and tubers weight plant -1 . Between nutritional traits total phenolic content (TPC), antioxidant potential (AOP) and ascorbic acid content (AA) were determined in the range: 36.2 to 65.1 mg gallic acid equivalent 100 g -1 fresh weight, 0.18 to 0.56 mg Trolox equivalents g -1 FW and 13.7 to 23.5 mg 100 g -1 FW, respectively. Significant interactions of growing media (factor A) × variety (factor B) were observed for thickness of vine-base, weight of above ground part, AOP, TPC and AA. Overall, results showed variation in varieties response to growing media. Growing media provide a discriminant classification of the sweet potato varieties according to their agronomic and nutritional traits. IntroductionSweet potato (Ipomoea batatas L.; Convolvulaceae) is ranking as the world's 7 th major food crop, which serves as an energy and phytochemical source of nutrition in more than 100 countries (FAOSTAT, 2017;Shekhar et al., 2015). The origin of sweet potato is Central America, but at present it is widely cultivated in the tropics and subtropics, and even in some temperate areas at different ecological regions (Chandrasekara and Kumar, 2016). In Europe, where the total production of sweet potato accounted 45.901 t in 2014, the biggest producers are Portugal (22.591 t), Spain (13.550 t), Italy (6723 t) and Greece (3038 t) (FAOSTAT, 2017). In Slovenia, sweet potato has been quite unknown crop until recently, both for production and human consumption. The environment diversity and specific climatic conditions of this region could enable successful production of that crop in the future (Kunstelj et al., 2013(Kunstelj et al., , 2015. Three new Slovenian sweet potato varieties (Lučka, Janja, Martina) were registered in 2015 and are now added to national list of varieties (National list of Varieties, 2016).Tubers of sweet potato are rich in dietary fibre, minerals, vitamins and antioxidants, such as phenolic compounds (Lebot et al., 2016;Tang et al., 2015;Teow et al., 2007). Besides acting as antioxidants, phenolic compounds and carotenoids also provide sweet...

“…These biomolecules can be extracted and applied in different industrial sectors to give value to the by‐product, thus A. lechuguilla exploitation. Aquaculture can benefit because the biomolecules present in the guishe represent a potential nutritional resource for some animals (Chandrasekara & Josheph Kumar, ; Chen, Tai, & Hsiao, ). Among the active biomolecules with nutritional properties for animals, saponins and flavonoids are reported to have beneficial effects in growth performance and immune system (Anaya‐Rosas, Rivas‐Vega, Miranda‐Baeza, Piña‐Valdez, & Nieves‐Soto, ; Cheeke, ; Das et al, ).…”

Evaluation ofAgave lechuguillaby‐product crude extract as a feed additive for juvenile shrimpLitopenaeus vannamei

et al. 2020

Agave lechuguilla is a succulent plant species, mainly distributed in the northeast of Mexico and south of the United States of America. The main use for this plant is the fibre´s extraction (known as Tampico fibres), resulting in 15% of fibres and 85% of a by‐product waste named guishe. The lechuguilla collectors, normally incinerate the guishe, thus causing environmental contamination. Interestingly, recent studies showed that guishe contains molecules with nutritional properties, such as saponins, flavonoids and sugars. Therefore, in this work, we evaluated the effect of the crude extract of guishe as a feed additive in whiteleg shrimp diets. According to that, MS‐HPLC analysis of the extract showed the presence of saponins such as diosgenin, smilagenin, hecogenin, manogenin, tigogenin hexose, yucagenin, chlorogenin, diosgenin diglucoside and the flavonol, quercetin. After chemical analysis, the crude extract was included into an experimental diet in four levels; 0% (L0%), 0.1% (L0.1%), 0.3% (L0.3%) and 0.6% (L0.6%). Dietary incorporation of the extract was evaluated by zootechnical performance, haemolymph biochemistry, histomorphology and digestive enzyme activity of shrimps. After 5‐week feeding, the L0.3% diet showed significantly higher growth and better feed utilization among treatments. A significant increase in tubule epithelium height and tubule coverage area from hepatopancreas in shrimp under L0.3% diet compared with the control diet suggest an improvement of the health and nutritional status of the shrimp. Inclusion of L0.3% and L0.6% of the crude extract resulted in a reduction in amylase activity, without effect in glucose levels in the haemolymph. Thus, we suggest that lechuguilla guishe crude extract contains nutritional molecules that may be used as a feed additive to promote shrimp productivity.
