We produced a prototype of dried cactus made from domestic cactus (nopal)

Agriture has produced a prototype of dried cactus made from domestically grown prickly pear cactus (nopal). Prickly pear cactus (scientific name: Opuntia ficus-indica and others) has long been eaten as nopalitos, a staple-level vegetable, mainly in Mexico, and its cultivation is spreading in warmer regions of Japan as well. Fresh cactus is hard to handle because of its spines and distinctive sliminess, so its distribution as a commercial ingredient has been limited. Drying it, however, allows it to be distributed at room temperature and turns it into a material that can be widely used in powder blends and as a food ingredient.

For this prototype, the cactus underwent careful pretreatment at our own processing facility in Kyoto Prefecture (spine removal, partial peeling and heat pretreatment) and was then dried at low temperature. Prickly pear cactus contains water-soluble dietary fiber (viscous polysaccharides such as pectin), minerals, calcium, magnesium and vitamins, and overseas it is treated as a functional material for health-oriented food ingredients. At Agriture we avoid exaggerated claims and design the ingredient around its ease of use and its functional appeal.

- Slices / dice: for ingredients and simmering
The pads (cladodes), with the skin pretreated, were cut into slices or dice and finished by low-temperature drying. Slices suit salads, stir-fries and soup ingredients, while dice suit stewed dishes such as minestrone and takikomi gohan (seasoned rice). When rehydrated, the soft texture and stickiness characteristic of cactus return, making it usable as an ingredient for commercial prepared foods, school lunches and retort pouch ingredients.

- Coarse grind to powder: for powder blends
We also milled the dried cactus further to offer specifications from coarse grind to fine powder. It is suited to formulations that make use of its color (pale green) and functional components, such as smoothies, health drinks, confectionery doughs, bread doughs, powder blends for health foods, and furikake and seasoning blends. Overseas it is used as a raw material for beauty- and health-concept powders and capsules.

Prototype Specifications and Choosing by Use

In this prototype, the drying conditions and uses change depending on the form the pads are finished in. The following specifications can be designed to match the intended final product.

• Slices: salads, stir-fries, toppings, and rehydrated ingredients for instant foods
• Dice: ingredients for soups, stews, curries and takikomi gohan, and retort prepared dishes
• Coarse grind: blended teas, Japanese herb-style mixes, furikake and seasonings
• Powder: smoothies and health drinks, raw material for health foods and supplements, and powder blends for confectionery and bakery

The viscous component of prickly pear cactus is classified as water-soluble dietary fiber consisting mainly of pectin. Because it retains water absorption and viscosity even in powdered form, product designs can make use of the thickness it gives when dissolved in drinks, its moisture-retaining effect in doughs and its dispersibility when blended with other ingredients.

Ideas for OEM and product development using cactus

Prickly pear cactus is an ethnic ingredient rooted in Mexican and Mediterranean food culture, yet interest in it is growing in Japan as well as an unusual health food and a functional plant. Here are the directions we most often discuss at Agriture.

• Commercial ingredients for Mexican and ethnic dishes (minestrone, taco fillings, salsa blends)
• Main ingredient for health-oriented smoothies and green drinks (a functional green material alongside kale and moringa)
• Health foods and supplements using prickly pear cactus powder (highlighting dietary fiber and minerals)
• Blending into cereals and granola with a diet or beauty concept
• Ethnic brands combined with dried fruit (nopal fruit, i.e. prickly pear fruit)
• Regional brands built around an unusual ingredient from identifiable domestic growing regions such as Okinawa and Kagoshima

From the standpoint of the Pharmaceuticals and Medical Devices Act, we recommend avoiding definitive claims of specific effects and designing messaging around the ingredient itself, such as "a functional plant containing water-soluble dietary fiber and minerals that is also attracting attention overseas" or "a health food ingredient originating in Mexico."

The raw material concept of domestic cactus

Imported prickly pear cactus ingredients (Mexican powders and juices) are available to some extent, but the concept of domestically grown cactus is an angle that makes differentiation easy in the health food and ethnic food markets. Because cultivation, harvesting and processing can all be completed within Japan, it suits brands that emphasize traceability.

At Agriture, we are developing prototypes with a system in which domestic prickly pear cactus is pretreated, dried, milled and packaged entirely under our management at our own processing facility in Kyoto Prefecture. Because the growing region, harvest timing and finishing conditions can be adjusted to the design of the final product, we can work with you to refine the product concept from the raw material selection stage.

About the minimum prototype lot and processing facility

We accept prototype orders from 1 kg of raw material. Whether slices, dice, coarse grind or powder, multiple conditions can be tested in parallel from small quantities, so you can consult us even at an early stage before the product concept is settled. Full production starts at 10 kg, and purchase lots, lead times and packaging formats are worked out case by case.

Processing takes place at our own facility in Kyoto Prefecture. The best-before date is about 6 months from shipment, and we can handle commercial bulk, small bags, sticks and light-shielding packaging. Cactus has a high moisture content and takes effort to pretreat, so having a system that handles everything from sourcing the fresh raw material to packaging after processing, available from the prototype stage, is a real strength.

Combining with other functional materials

Prickly pear cactus can be used on its own as the main ingredient in health foods, but combining it with other functional materials broadens the range of product concepts. Dried Moringa (a vitamin- and mineral-type leafy green), Dried Ashitaba (a chalcone-type leafy green), Ashitaba powder (a fine powder for green juice and supplements), Dried mugwort (a Japanese-herb type), and others—blend designs combining these can be advanced together with a single material-supply source, which is a strength.

We also take on product designs that combine the character of different ingredients, such as a green powder of cactus, moringa and ashitaba, a blended tea of cactus, yomogi and Japanese herbs, or an ethnic health drink with cactus as the star. Let's work out the final product specifications, lots and schedule together from the prototype stage.

Agriture also handles drying and powdering OEM and commercial ingredient prototypes for unusual functional plants, including domestic prickly pear cactus (nopal). Companies interested in developing health foods, smoothies, ethnic foods, confectionery or other products using cactus are welcome to contact us.

Dried turnip can be expected to attract commercial interest as a material for soups, simmered dishes, and pickles, and if processed into powder, it can also be used as a raw material for baby food and nursing-care food. Turnip's characteristic gentle flavor is a material well compatible with children's foods and products for the elderly.
