Summary of Petition

The petitioner summary of the pesticide petition is printed below as required by FFDCA section 408(d)(3). The summary of the petition was prepared by the petitioner, and represents the view of the petitioner. The petition summary announces the availability of a description of the analytical methods available to EPA for the detection and measurement of the pesticide chemical residues or an explanation of why no such method is needed.

Hydrogenated Starch Hydrolysate

PP 2E6503

EPA has received a pesticide petition (2E6503) from Grain Processing Corporation, 1600 Oregon Street, Muscatine, Iowa 52761 proposing, pursuant to section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part 180 to establish an exemption from the requirement of a tolerance for hydrogenated starch hydrolysate (HSH) in or on growing crops or when applied to the raw agricultural commodity after harvest. EPA has determined that the petition contains data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the petition. Additional data may be needed before EPA rules on the petition.

A. Residue Chemistry

1. Plant metabolism. Like any other carbohydrate, HSH degrades readily in the soil and other substrates into carbon dioxide and water. HSH (CAS number 68425-17-2) is a carbohydrate polymer with a theoretical molecular weight (in amu) of 1,000-3,600. It can be supplied as a liquid syrup or white powder. The empirical formula of the components of HSH are:

ComponentsFormula
SorbitolC6 H14 O6
MaltitolC12 H24 O11
Hydrogenated polysaccharidesC12 H24 O11 plus C6 H10 O5 for each additional glucose moiety in the chain

HSH is highly soluble in water. The aqueous solution has a pH range of 4.0-6.0. It hydrolyzes slowly to glucose and sorbitol. It combusts at 3000 C to carbon dioxide and water.

2. Analytical method. The qualitative analysis of HSH in the products to which it has been added may be accomplished by extraction of the sorbitol and maltitol moieties with appropriate solvents, followed by gas chromatography of the extracts. Similarly, the quantity of HSH occurring in food may be estimated by determining the amount of maltitol recovered and applying an appropriate factor. Information on the sensitivity and reproducibility of the method has also been developed.

3. Magnitude of residues. HSH is readily degraded by microorganisms on leaf surfaces and in the soil. Due to the solubility of this carbohydrate, rain, or other water sources wash the carbohydrate into the soil where it is degraded by microorganisms into carbon dioxide and water. No harmful residues are produced.

B. Toxicological Profile

HSH has been widely used in foods since the early 1980s. It has been marketed extensively by Roquette, Lonza and SPI Polyols for years. Grain Processing Corporation produces HSH using a process that is equivalent to the process petitioned to the Food and Drug Administration by Lonza and Roquette Freres for GRAS (generally recognized as safe) affirmation. In support of the safety of our HSH, Grain Processing Corporation and SPI Polyols cites data Start Printed Page 65118submitted by Roquette in its Lycasin® 80/55 petition regarding numerous studies relating to the safety of the ingredient, including reports on: Digestion, absorption, distribution and excretion; acute oral toxicity, subchronic toxicity, genotoxicity, reproduction, biological tolerance, human exposure, and laxation effects.

1. Acute toxicity. The acute oral toxicity of HSH has been evaluated. The acute oral lethal dose (LD50) of HSH is greater than 10 grams/kilogram (g/kg).

2. Genotoxicty. As stated in Roquette's GRAS submission of Lycasin® 80/55, HSH is nonmutagenic and nonclastogenic in short-term in vivo, and in vitro studies.

3. Reproductive and developmental toxicity. Again as noted in Roquette's GRAS submission of Lycasin® 80/55 HSH products, when administered to rats over 3-generations, produce no significant effects on reproduction.

4. Subchronic toxicity. In Roquette's GRAS submission for Lycasin® 80/55, it is noted that when administered orally to rats and dogs in amounts of 5 g/kg to 15 g/kg of body weight per day for 90 days, HSH produced no toxicologically meaningful effects which could not be accounted for by the presence of sorbitol. The possible treatment related effects are aggregates in the renal pelvis of some rats, diarrhea in most dogs, and minimal ectasia in the renule tubules of some dogs.

5. Chronic toxicity. HSH is used extensively in foods. Grain Processing Corporation is not aware of any chronic toxic effects associated with this product.

6. Animal metabolism. The GRAS submission for Lycasin® 80/55 developed by Roquette Freres states that over 96% of HSH (Lycasin® 80/55) is broken down by the mammalian digestive system into the GRAS substances, glucose and sorbitol, the remaining 4% is in the form of maltitol. One half of the maltitol is excreted in the feces and the majority of the remainder is excreted in the urine.

Within the first 2 hours after oral administration of HSH (Lycasin® 80/55), virtually all of the glucose to glucose bonds are broken down in the digestive system, producing a resulting mixture of glucose, sorbitol, and maltitol. Within 7 hours, 95% of the total maltitol, is broken down into glucose and sorbitol. Of the remaining 5% of maltitol, 2% is found in the digestive tube and fecal contents, less than 1% is found in the plasma, and approximately 1% is excreted in the urine.

There is no accumulation of maltitol in the plasma, liver, kidneys, or spleen of rats fed 13.5 g/kg/day of Lycasin® 80/55 for 10 days irrespective of whether measurements are made 12 hours or 10 days after cessation of dosing.

Lycasin® 80/55 at the dose levels tested, 30 to 180 grams per day, produces no significant variations in the clinical chemical, hematological or urinary profile of humans with the exception of glucose and insulin peaks which are less than 50% of those produced by equivalent amounts of glucose, and 50 to 90% of those produced by sucrose. The only significant clinical effects are flatulence and diarrhea, which can be accounted for by the presence of free and bound sorbitol. The mean laxative threshold in adult males is approximately 180 grams per day, while in females the threshold is approximately 100 grams per day. In children, the threshold is approximately 60 grams per day, about half that of adults.

7. Metabolite toxicology. None of the metabolites of HSH are considered to be of toxicological significance for the use of this product as a pesticide inert ingredient.

8. Endocrine disruption. Grain Processing Corporation is not aware of any endocrine disruption with the use of this product.

C. Aggregate Exposure

1. Dietary exposure. This product is already used extensively in foods. Studies have shown that it is safe even when consumed at levels of up to 100 g/day.

i. Food. As a pesticide inert ingredient HSH will not result in any harmful exposure. The proposed use will not result in any dietary exposure beyond what is currently present in commonly consumed foods.

ii. Drinking water. There is no anticipated human exposure to HSH through drinking water. HSH is expected to be degraded by soil microorganisms to carbon dioxide and water before it reaches surface or ground water. Moreover, in water, HSH hydrolyses to glucose and sorbitol.

2. Non-dietary exposure. No significant non-dietary human exposure to HSH is anticipated.

D. Cumulative Effects

HSH is a widely used food ingredient, is readily digested by humans, and there are no cumulative effects. Except for possible occupational exposure of the pesticide mixer/loader/applicator, the proposed use of HSH will not result in the exposure of other persons.

E. Safety Determination

1. U.S. population. The proposed use of HSH does not pose a safety concern for the U.S. population due to the non-toxic nature of the compound and the absence of exposure.

2. Infants and children. Infants and children will not be exposed to HSH from its proposed use as a pesticide inert ingredient.

F. International Tolerances

Grain Processing Corporation is unaware of any international tolerances for this product. HSH was developed by a Swedish company in the 1960's and has been widely used by the food industry for many years, especially in confectionery products. Roquette's petition indicates that Roquette's Lycasin® products have been approved for use in food in Europe since 1963, as indicated below.
