l-arabinose

Identity Before Grade

L-arabinose is a five-carbon monosaccharide with the molecular formula C₅H₁₀O₅ and a molecular weight of 150.13 g/mol. The “L” identifies its stereochemical form, so a purchase specification should state L-arabinose rather than the broader name arabinose.

The Sgnutri product page identifies the supplied material as CAS 5328-37-0. The product specification lists a specific rotation of +102° to +105°. These fields work together: the name identifies the intended stereoisomer, while optical rotation provides an identity-related acceptance range for the supplied material.

The Sgnutri product page uses CAS 5328-37-0. The NIST Chemistry WebBook records L-arabinose under 87-72-9, and PubChem lists both identifiers. When product documents use different identifiers, confirm that the name, stereochemistry, specific rotation and chemical structure describe the intended material.

Match the Physical Form to the Food Process

Sgnutri’s L-arabinose is a sweet, water-soluble crystalline powder that passes a 20-mesh screen. These features determine how the ingredient enters a formula; the complete recipe and process determine the finished result.

Aqueous Formulations

Water solubility allows the powder to be dissolved in process water before it enters a beverage, syrup or other aqueous system. This route supports even distribution through the liquid phase. Dissolution time, clarity and taste should be measured at the formula’s actual concentration, water temperature and pH because those conditions change how quickly the powder incorporates and how the complete product tastes.

Dry Mixes and Bakery Preblends

The specification that the powder passes 20 mesh provides a coarse particle-size limit, but it does not describe the full particle-size distribution. A preblend can improve distribution when L-arabinose is used at a much lower level than flour, sugar or another major dry ingredient. Blend uniformity should be checked after handling because large differences in particle size or bulk density can cause segregation and uneven dosing.

Storage and Handling

Store the crystalline powder in dry, ventilated conditions and protect the opened package from humidity. Moisture exposure can promote clumping and make weighing and dissolution less consistent. The listed shelf life is 24 months. State the applicable start and expiry dates on the purchase specification so receiving and stock rotation use the same basis.

Interpreting Sucrose Research for Product Development

L-arabinose has been studied for its interaction with sucrase, the intestinal enzyme that breaks sucrose into glucose and fructose. In a randomized crossover study in healthy adults, 7.5 g of L-arabinose taken with a drink containing 50 g of sucrose delayed the appearance of sucrose-derived glucose and reduced the early post-meal glucose and insulin response compared with sucrose alone.

A 2025 crossover trial in adults with impaired fasting glucose found a lower and later glucose and insulin peak after 5 g of L-arabinose was added to a drink containing 50 g of sucrose. The same study did not find an effect on continuous-glucose-monitoring variability during a two-day diet of mixed sucrose-rich meals and snacks. The difference between the drink test and the mixed diet shows why dose, timing and the complete food matrix must remain part of development work.

For a sucrose-containing prototype, vary the L-arabinose-to-sucrose ratio and compare taste, process behavior and the chosen analytical response in the complete recipe. The mixed-diet result shows that an acute drink result should not be projected unchanged to a multi-component food.

Read U.S. Regulatory Records Precisely

The FDA Substances Added to Food database lists L-arabinose under CAS 5328-37-0 and identifies its technical effect as a flavor enhancer, flavoring agent or adjuvant. This record provides a useful identity and use reference for U.S. food development.

GRAS Notice 782 describes another notifier’s L-arabinose and proposed uses as a carbohydrate source, sucrose replacement or replacement for other sweeteners in specified food categories at 0.1%–10% by weight. The FDA’s current detailed record states that the agency ceased evaluating that notice at the notifier’s request. It does not provide an FDA “no questions” conclusion that can be transferred to every L-arabinose product.

For a U.S. food project, the regulatory assessment should connect the specific ingredient identity and manufacturing information with the intended food category, use level and label.
