The cactus fruit is consumed as a traditional medicine and food in Mexico. In contrast to the common fruit (tunas) from related Opuntia ficus-indica, it is less sweet, the color is a bland greenish, and it is more used for traditional medicine than cuisine. Its taste is more acidic (due to citric acid). It has many green seeds in the central pit which is covered in red pigment from its antioxidant betalains. The fruits are sold in food markets in Mexico, in produce stalls and used in salsas.
Xoconostle cv. Cuaresmeño (Opuntia matudae) has attracted domestic and international industry attention; however, variations of composition from xoconostle structures have not been evaluated. Industries discard the pulp (endocarp) and peel (pericarp) as wastes and utilize the skin (mesocarp), which is the edible portion. The physicochemical, nutritional, and functional characterization of structures from xoconostle pear from 3 major sites of production in Mexico were assessed. Skin yield ranged from 58% to 64% and was higher to that of peel (22% to 24%) and pulp (12% to 18%) yields. pH, degrees Brix, and acidity were similar among xoconostle structures. Total fiber showed by peel (18.23% to 20.37%) was 2-fold higher than that of skin. Protein and ether extract were higher in xoconostle pulp compared to that showed by peel and skin. Iron content of xoconostle peel (6 to 9.6 mg/100 g, DWB) was higher to that of skin and pulp and prickly pear pulp. Soluble phenols of peel (840 to 863 mg GAE/100 g, DWB) were almost similar to that of skin (919 to 986 mg GAE/100 g, dry weigh basis); meanwhile, ascorbic acid concentration of skin was 2-fold higher compared to that of peel. The phenolic fraction of xoconostle structures consisted of gallic, vanillic, and 4-hydroxybenzoic acids; catechin, epicatechin, and vanillin were also identified by high-performance liquid chromatography-didoe array detection (HPLC-DAD). Xoconostle peel showed higher antioxidant activity (TEAC) compared to that of skin (2-fold) and pulp (6-fold) of commonly consumed fruits and vegetables. The potential of xoconostle peel and pulp for the production of feed or food is promissory. Practical Application: Outstanding nutritional and functional properties of xoconostle cv. Cuaresmeño fruits are demonstrated. Increased consumption could contribute positively to improve the diet of rural and urban consumers. The high fiber, mineral, and antioxidant components of xoconostle peel and pulp suggest that these fruit structures, which are currently discarded as waste, have promissory use as feed or food by industry.

Plant Germplasm (definition): Any portion of genetic material that can be grown into a live plant. Examples include seeds, stem cuttings (via many methods including air layering), root cuttings, root divisions (multiplication via division), leaf cuttings, leaf fragments (in tissue culture), rooted nodes (vines), “eyes” (offshoots from potato tubers), cacti pieces, etc. The term germplasm can also be used to describe a collection of genetic resources for an organism such as as a seed collection or, for trees, a nursery.MASS SPECTRUM BOTANICALS (Tampa, Florida): Germplasm Factory - Micronursery - Commercial Seed Bank Areas of Intent & Expertise: >Custom heirloom vegetable seed vaults. >Live Plants of a useful nature (exotic fruits, tactical landscaping plants, etc.). >Plant growth hormone regulators (PGR's) and other Plant Biostimulants. >Rare edible perennial jungle plants (green leafy vegetable year round tropical plants). >Drought tolerant edible landscape xeriscaping. >Complimentary Cancer Survival medicinal plants; >Cutting edge skin, weight & diabetes health targeting. >Laboratory-spec seed sprouting, germination & vegetative propagation kits. >Advanced horticultural science. >Ethnobotanical supplies. >Isolated herbal extracts.
