Sweet potato powder is an ingredient made by finely powdering heat-saccharified sweet potato, intended to spread sweetness and a yellow-to-orange color evenly into lattes, drinks, confectionery batters, baby food, and soup-powder bases. At Agriture, using the same raw material asDried sweet potato<\/a>, it is an ingredient strong in recipe designs where the dispersibility of the powder is effective\u2014coloring lattes, smoothies, baby food, bakery batters, and the like.<\/p>\n\n\n\n

Agriture's sweet potato powder: three commitments<\/h2>\n\n\n\n

1. Drawing out saccharification before powdering<\/h3>\n\n\n\n

The sweetness of sweet potato is created when \u03b2-amylase breaks down starch into maltose around 65\u201375\u00b0C. At Agriture, we pass through this temperature range for a longer time during steaming before grinding, advancing saccharification sufficiently before moving on to drying and grinding. We set our finishing standard at a level where a sweetness close to steamed sweet potato spreads the moment you take the powder into your mouth. We organize the strengths unique to sweet potato powder from six perspectives.<\/p>\n\n\n\n

\n
\n

Natural sweetness spreads into liquids<\/p>\n

Because it is saccharified by steaming before powdering, a sweetness close to steamed sweet potato rises up simply by dissolving it in water, milk, or soy milk. It is suited as a core ingredient for confectionery and beverage designs that aim to reduce the amount of sugar and sweeteners.<\/p>\n<\/div>\n

\n

Dispersibility in liquids and powders<\/p>\n

Even when dissolved in lattes, soups, or dressings, the graininess is hard to notice, and it disperses evenly in powder mixes. A strength of the powder is that it can be used as is, with no reconstitution needed.<\/p>\n<\/div>\n

\n

Coloring in yellow to orange<\/p>\n

Sweet potato's natural yellow to orange gently takes to batters, beverages, and creams. It is suited to product designs that want to produce an autumn-and-winter color gradation without using synthetic coloring agents.<\/p>\n<\/div>\n\n

\n

Compatibility with baby food and nursing-care food<\/p>\n

Thanks to its natural sweetness, easily digestible starch, and tendency to thicken, it is an ingredient we are often consulted about for the staple-food base of baby food and the dysphagia-food design of nursing-care food. A base can be made simply by dissolving it in hot water.<\/p>\n<\/div>\n

\n

Use together with the ingredient-shape version<\/p>\n

A strength is that it can be reconstituted and used directly as an ingredient.<\/p>\n

Commitments to variety, grower, and growing region<\/h2>\n\n\n\n

Sweet potato is a root vegetable of the Convolvulaceae family that has long been enjoyed in Japan as well, with design latitude in saccharification through storage and the rise of sweetness through heating. As a powder raw material, using individuals with a high sugar level in combination with steaming lets you draw out sweetness and color to the maximum.<\/p>\n\n\n\n

\n

BRAND \u2014 the positioning of sweet potato powder<\/p>\n

As a Japanese root-vegetable powder with the culture of yaki-imo and hoshi-imo in the background, sweet potato powder is a highly versatile ingredient in the confectionery, beverage, baby-food, and cereal fields. At Agriture, we design it as a material starting point for latte, drink-mix, and baby-food OEM.<\/p>\n

PRODUCER | Basic policy for sourcing and coordination<\/p>\n

We coordinate directly with production areas on off-grade and processing-bound lots and select raw materials that readily take on a high sugar level and have stable color. Sending raw material whose sugar level has risen through storage (curing) to drying and grinding stabilizes the sweetness of the powder.<\/p>\n

REGION | Characteristics of the main growing region<\/p>\n

Kagoshima, Ibaraki, Chiba, and Miyazaki are the main domestic producing areas. The good drainage of volcanic-ash soil and the warm climate contribute to a tendency toward high sugar levels. At Agriture, we use these producing areas differently according to the use and the finished color and sweetness.<\/p>\n

CULTIVATION \u2014 storage, saccharification, and powder quality<\/p>\n

By going through 2\u20133 months of storage after harvest, the starch turns into sugar and the sweetness increases. Because lots with little storage remain weak in sweetness even after powdering, we select only raw materials properly matured at the production area for powder use.<\/p>\n<\/div>\n\n\n\n

Low-temperature drying technology and quality control<\/h2>\n\n\n\n

For sweet potato powder, how the sweetness, color, and aroma remain changes at each step of steaming, drying, and grinding. At Agriture, we manage everything consistently from raw-material preparation to packaging, and we have a system in place to curb variation between lots.<\/p>\n\n\n\n

Making use of \u03b2-amylase through steaming<\/h3>\n\n\n\n

By passing through around 65\u201375\u00b0C for a longer time during the steaming before grinding, the starch is broken down into maltose. If this step is omitted, the sweetness is weak even when finished as powder, and a raw-starch feel remains when dissolved in water.<\/p>\n\n\n\n

Drying temperature and maintaining color<\/h3>\n\n\n\n

Sweet potato, which contains a lot of sugar, turns brown in color and loses its sweet aroma when dried at high temperatures. By lowering the temperature during the moisture-removal stage and drying in stages, we retain a vivid yellow-to-orange color in the powder. We organize the uses we are often consulted about into six categories.<\/p>\n\n\n\n

1. Lattes, drinks, and cafe menus<\/h3>\n\n\n\n
