Pinqing offers the following product series (each produced to Chinese national standards; detailed specifications are on the product page):
Positioning, key parameters and application summary for each series; please contact sales for the full specification sheet.
A prebiotic oligosaccharide supplied in type 55 and type 95 grades; liquid dry solids ≥75%, solid (powder/granule) moisture ≤5.0%, pH 4.5-7.0.
A functional oligosaccharide syrup based mainly on isomaltose, panose and isomaltotriose, supplied as IMO-50 and IMO-90; syrup dry solids ≥75%, pH 4.0-6.0, transmittance ≥95%; powder moisture ≤5%, solubility ≥99%.
Blended on a syrup base to the required flavour, sweetness and acidity, with OEM/ODM private-label production; flavour strength and Brix are confirmed by sampling.
Fructose content (on dry solids) ≥90%, fructose + glucose ≥95%, dry solids ≥75%, pH 3.3-4.5, colour ≤50 RBU, transmittance ≥96%.
Three grades by fructose content: ≥42%/≥55%/≥60% (on dry solids), fructose + glucose ≥92%/≥95%/≥95%, dry solids ≥70.5%/≥76.5%/≥72.5%.
Both are functional oligosaccharides. They differ mainly in glycosidic structure, sweetness profile and process tolerance; they can also be used in combination.
| Item | Fructo-oligosaccharide (FOS) | Isomalto-oligosaccharide (IMO) |
|---|---|---|
| Glycosidic bond and main components | Sucrose-type (beta-2,1 bonds), mainly GF2 to GF4 | Alpha-1,6 bonds, mainly isomaltose, panose and isomaltotriose |
| Standard grades (on dry solids) | Type 55 ≥55%; type 95 ≥95% | IMO-50 ≥50%; IMO-90 ≥90% |
| Relative sweetness (sucrose = 100) | approx. 30-60 | approx. 40-60 |
| Sweetness profile | Clean and pure, close to sucrose; suitable for blending with high-intensity sweeteners | Mild and rounded with good sweetness carry-over and flavour carrying |
| Process tolerance | Stable at neutral pH (4-7) and under normal sterilisation and baking; little Maillard browning at high temperature | Heat and acid tolerant; suits bakery, dairy and acidic beverage systems |
| Typical applications | Fibre-enriched beverages, fermented dairy, infant formula, health foods | Dairy, bakery, beverages and lactic acid drinks, confectionery, functional foods |
| Standard | GB/T 23528.2-2021 | GB/T 20881-2017 |
The four grades differ in fructose content: the higher the grade, the sweeter the syrup and the stronger the cold-sweetness effect. Grade selection follows the sweetness target and process conditions of the finished product.
| Parameter | F42 | F55 | F60 | F90 |

| Dry solids | ≥70.5% | ≥76.5% | ≥72.5% | ≥75% |
| pH | 3.3-4.5 | 3.3-4.5 | 3.3-4.5 | 3.3-4.5 |
| Colour | ≤50 RBU | ≤50 RBU | ≤50 RBU | ≤50 RBU |
| Sulphated ash | ≤0.05 g/100g | ≤0.05 g/100g | ≤0.05 g/100g | ≤0.05 g/100g |
| Transmittance | ≥96% | ≥96% | ≥96% | ≥96% |
| Relative sweetness (sucrose = 1) | approx. 1.0 | approx. 1.05 | approx. 1.1-1.2 | approx. 1.2-1.6 (sweeter at lower temperature) |
| Typical use | General sweetening and humectancy: beverages, bakery, canned fruit | Mainstream beverages: carbonated, juice, dairy drinks | High-sweetness beverages, bakery browning and flavour carrying | Reduced- and zero-sugar formulas, cold drinks, jams, confectionery |
Our full-spectrum products cover diverse food and beverage applications:
Standard and high-sweetness sugar source for carbonated, fruit-flavored, and functional drinks, refreshing and anti-crystallization.
Improves smoothness and suppresses ice crystal formation; caramel syrup used for toppings and flavored fillings.
Sweetness and texture adjustment for fermented milk, dairy drinks, and fresh-brewed teas.
Excellent compatibility with gel systems, clean sweetness, and uniform sweetness release.
Moisture retention, anti-crystallization, and flavor carrier properties improve texture and shelf life.
Prebiotic applications of IMO syrup, and energy supplementation for aquaculture feed.
Provides fermentable sugar source, helping regulate fermentation degree and body balance.
Preserves aroma and color with stable osmotic properties, maintaining fruit shape and appearance.
Customized delivery from requirements to mass production
Understanding application scenarios, specifications, and flavor needs, defining specs and delivery schedule.
Providing samples and small-batch trial orders (minimum 1 ton) to verify specifications and taste.
Standardized production with 13% VAT invoice, factory-direct logistics or tanker delivery.
Stable supply and quality tracking, supporting reorder and formula iteration.
Common questions on grade selection, specification data and commercial terms; contact our sales team for further detail.
Select by the sweetness target and process conditions of the finished product: F42 for general sweetening and humectancy, F55 as the mainstream beverage grade, F60 for high-sweetness beverages and bakery browning, and F90 for reduced- and zero-sugar formulas and blended sweetener systems.
See the comparison table on this page: fructose content ≥42%/≥55%/≥60%/≥90%, fructose + glucose ≥92%/≥95%/≥95%/≥95%, dry solids ≥70.5%/≥76.5%/≥72.5%/≥75%, pH 3.3-4.5 for all grades, colour ≤50 RBU and transmittance ≥96%.
Choose FOS (type 55/type 95) when the focus is fibre enrichment, infant formula or health foods; choose IMO (IMO-50/IMO-90) when sweetness and texture control in dairy, bakery and beverages is the priority. The two can also be blended in one formula.
Yes. Contact the sales team to receive specification sheets, packaging options, samples and batch certificates of analysis (COA) for all five series in one request.
Products are made from starch and sucrose by enzymatic conversion and separation/purification. If a project requires non-GMO (IP) statements or system documents, please confirm this at the enquiry stage; the formal documents provided prevail.
Standard packaging is 25 kg drums (liquid) and 25 kg bags (solid); 1,000 kg IBC totes and food-grade bulk tankers are also available. The MOQ for customised and private-label orders is 1 tonne, with small trial orders accepted.
