Case 2766-CIP-1 Description LOW-CALORIE FOODS
TECHNICAL FIELD
This invention relates to the fabrication and 05 manufacture of low-calorie food products which contain a high level of polysaccharides (e.g., polydextrose, polymaltose, modified polydextrose, etc.) and/or polyols (e.g., sorbitol, glycerol, erythritol, xylitol, mannitol, galactitol, etc.~.
The substitution of non-nutritive, non-fiber bulking agents, such as polysaccharides and polyols, for all or a portion of the caloric, metabolically-active ingredients such as starch or sucrose is well known as a technique of reducing the caloric value of a foodstuff. It has been found, however, that the ingestion of polysaccharides and/or polyols in amounts as low as 30 to 100 grams per day can cause some people to suffer from gastrointestinal discom-fort and diarrhea. Accordingly, the use of these materials in low-calorie food products has been limited.
The production of both soluble and insoluble polysaccharide materials is known to the art, as ex-emplified by U.S. Patent Number 3,766,165 which teaches polycondensation of saccharides at reduced pressure in the presence of polycarboxylic acids cat-alysts. This patent also discloses the inclusion of food acceptable polyols in the saccharide-carboxylic

The present invention relates to the control of diarrhea induced by ingesting low-calorie foodstuffs which contain polysaccharides and/or polyol mate-rials. According to this invention, dietary fiber preparations are incorporated into polysaccharide and/or polyol-containing foodstuffs at a level sufficient to exhibit an antidiarrheal effect.
As will be recognized by those skilled in the art, small amounts, typically up to about 5% dry weight basis of the total dietary intake, of poly-saccharides and polyols can be ingested without causing any adverse gastrointestinal effects.
Various individuals will be able to ingest varying amounts of polysaccharides and/or polyols without adverse effect; however, as the diets of the indivi-duals consuming a polysaccharide and/or polyol-con-taining foodstuff is not controlled by the food manufacturer, it is advisable to take preventitive measures in connection with all foodstuff which contain significant amounts of polysaccharides and/or polyols. This will particularly be true when the foodstuff is marketed as a low-calorie product and is but one of a series of low-calorie, polysac-charide and/or polyol-containing products which a 7~90 weight conscious consumer might ingest during the day.
The polysaccharides that are contemplated for use in this invention include polyglucose and poly-05 maltose in either their soluble or insoluble form.
The materials may be homopolymers -of glucose and maltose or be modified polymers of these materials, such as described in the aforementioned Pfizer patents. For instance, the glucose or maltose moieties may be esterified or contain a chemically bonded, food-acceptable polyol such as sorbitol.
The polyols that are contemplated for use in this invention may be any of the polyhydric alcohols suitable for use in foods, including glycerol, sorbitol, propylene glycol, mannitol, xylitol, erythoritol and galactitol.
The dietary fiber preparations evaluated for use in this invention include edible fiber materials derived from grains, fruits and vegetables which contain an amount of cellulose fiber. Materials wherein the dietary fiber consists essentially of hemi-cellulose or consists essentially of pectin substances and which do not contain any cellulosic fiber have not been found suitable for purposes of this invention. Among the dietary fiber prepara-tions which have been found to reduce severity of polysaccharide and/or polyol-induced diarrhea are corn hull fiber, wheat bran, and alpha-cellulose;
however, preferred for use in this invention are the fiber materials known as soy fiber concentrate (SFC), citrus albedo, especially orange albedo, pineapple core bulking agent and sugar beet pulp ~7~91D
bulking agent. These materials are preferred be-cause their anti-diarrheal activity has been demon-strated to be higher than the other dietary fiber materials which have been tested. Specifically, rat 05 studies have shown that at certain identical levels, several dietary fibers are capable of reducing polysaccharide and/or polyol-induced diarrhea;
whereas, SFC, citrus albedo, pineapple core bulking agent and sugar beet pulp bulking agent were able to completely control (i.e., eliminate) polysaccharide and/or polyol~induced diarrhea.
Soy fiber concentrate is the material obtained by deoiling dehulled soybeans followed by water extracting the deoiled material. Soy fiber con-centrate is essentially the cell wall material re-maining after soybeans have been dehulled and the oil, protein and soluble carbohydrates have been extracted.
Citrus albedo is the whitish inner portion of the rind of citrus fruit that is commonly regarded as a source of pectin, and typically contains on the order of 40% pectin and 27% cellulose by weight.
The crude albedo is preferably extracted with water to remove soluble carbohydrates and may also be extracted with isopropyl alcohol to remove any off-colors and off-flavors. Such treatment will yield a material which can be dried and ground to produce a bland-tasting, fiber-containing albedo flour which is useful as a low-caloric bulk filler.
Pineapple core is a waste by product of the pineapple canning industry. The pineapple core is coarsely ground or shreaded, extracted with water to remove soluble carbohydrates and may also be ex-tracted with isopropyl alcohol to remove any off-flavors and off-colors. After drying and grinding, the pineapple core bulking agent thus produced is a 11 ~72~90 bland, decolorized, fiber-containing material which is low in calories and which is useful as a bulk filler. The pineapple core bulking agent contains approximately 5 to 10% total pectin, approximately 05 35% cellulose and approximately 30% hemicellulose on a dry weight basis. --Sugar beet pulp is a waste by product of thesugar industry. The sugar beet pulp, usually in the form of sugar beet cossettes can be collected from a sugar beet processing plant and placed in a solution of sodium metabisulphite to prevent darkening of the pulp due to polyphenol oxidase activity. The Sugar beet pulp can be drained and further processed or frozen stored. The sugar beet pulp material is coarsely ground or sliced, water washed to remove soluble carbohydrates and may also be extracted with isopropyl alcohol to remove any off-colors and off-flavors. When the material is dried and ground a whitish, bland-tasting, fiber-containing bulk filler is produced which contains approximately 25 to 30% cellulose, 15% hemicellulose and 15 to 20%
pectin on a dry weight basis.
Materials such as polysaccharide and polyol are believed to induce diarrhea because they are not metabolized or otherwise broken down in the stomach or small intestine and move rapidly into the colon.
It is further speculated that because of an osmotic and metabolic effect of the fermentation products of polysaccharides, and polyols large amounts of water are pulled into the colon where bacterial fermenta-tion rapidly occurs. A high water and gas level will facilitate adverse activity within the colon and produce a diarrheal condition.
1~7~ 9 Fiber material has been generally thought of as a means to decrease transit times and increase fecal output, or, in other words, to promote a favorable laxation, stool softening and bulking effect. It 05 was, therefore, surprising to discover that selected naturally-occurring fiber materials are able to control and/or alleviate polysaccharide and/or polyol-induced diarrhea.
Best Mode For Carrying Out The Invention The present invention will be applicable to low-calorie food products which contain in excess of 10% by weight (dry basis) of polysaccharides and/or polyols. For purpose of this invention, the term "low-calorie food" is used to represent foods having a caloric cbntent of 50% or less of the caloric value of corresponding ordinary food. Thus, a low-calorie cake is one that has only half or less than half of the calories of the same type of cake prepared with standard ingredients. Typically, the low-calorie food products of this invention will have a calorie content of less than about 2 calories per gram. The products of this invention will preferably contain a level of polysaccharides and/or polyols of at least 20% by weight (dry basis) and may reach levels as high as 60% or more by weight (dry basis). The amount of dietary fiber composi-tion which is present in the products of this inven-tion will range from 1/4 to 2 times the combined level of polysaccharides and polyols contained in the product, and preferably will be at from l/2 to about 1.5 times this level, and typically will be about 1.0 times this level.
When soluble polysaccharides are employed, they will, as recognized by those skilled in the art, ~2~90 typically be utilized in combination with artificial or other intensive sweeteners as replacements for natural sugars. Polyols which are soluble and possess varying levels of sweetness may also be 05 utilized as sugar replacements, either alone or in - combination with intensive sweeteners. Insoluble polysaccharides will typically be used as a replace-ment for flour.
As will be recognized by those skilled in the art, the presence of the fiber component within the formulations contemplated by this invention might render such formulations undesirable for certain products in which the consumer would not readily accept a fiber component. The formulations of this invention are, however, suitable for use in a wide range of low-calorie foodstuffs, including baked goods, (e.g., breads, cakes, etc.) puddings, confec-tions, pastas, noodles, jams, toppings, sauces and dressings. The determination of the levels of various standard food ingredients to be used in formulating the low-calorie products of this inven-tion can be readily made by those skilled in the art. Standard manufacturing procedures can be applied to the production of these products.
Animal studies employing young adult male Sprague Dawley rats have demonstrated the effective-ness of adding dietary fiber to diets which contain high levels of modified polydextrose and/or polyols.
In this experiment, the animals were fed with a standardized diet containing on a weight basis 18%
casein, 10% water, 8% corn oil, 4% salt, 1% vitamin mix and 59% cornstarch and were allowed 150 grams of diet each week. The animals exhibited no diarrhea ~ ~ 2~9 ~
on this diet. Test diets were formulated by substi-tuting modified polydextrose (MPD), polyol and/or fiber material for an equal weight of the corn-starch. The animals' feces was observed each day 05 and rated according to the following laxation fecal scoring scale: ;
-1 - no feces 0 - no diarrhea 1 - mild diarrhea, soft formed stool but stringy or irregular 2 - moderate diarrhea, very soft stools, mounded
acid reaction mixture prior to polycondensation to yield a modified polysaccharide having improved color and taste.

on this diet. Test diets were formulated by substi-tuting modified polydextrose (MPD), polyol and/or fiber material for an equal weight of the corn-starch. The animals' feces was observed each day 05 and rated according to the following laxation fecal scoring scale: ;
-1 - no feces 0 - no diarrhea 1 - mild diarrhea, soft formed stool but stringy or irregular 2 - moderate diarrhea, very soft stools, mounded
3 - severe diarrhea, liquid stools Test diets were fed for 14 days and each animal was given a diarrheic score which was the sum of its 14 daily scores. The median diarrheic score of the animal group was used in evaluating the respective test diets and the results set forth in Table I were obtained.

As can be seen from the above results, both xylitol and MPD are capable, at sufficient levels in the diet, of producing a diarrhea condition and that the addition of wheat bran to the diet is able to 05 reduce the severity of the diarrhea condition.
An additional study to assess the laxati~on effects of various levels of dietary fiber was made using male Sprague Dawley rats (201 to 225 gms.) which were fed ad libitum for 14 days. During this time, the fecal output for each of the various rat diets were scored according to the following laxa-tion fecal scoring scale:

The following tests (See Tables V and VI) which utilize the same procedure and laxation fecal ~ ~7 ~0 scoring scale employed to obtain the results in Tables II and III have demonstrated the effective-ness of pineapple core bulking agent and sugar beet pulp bulking agent in the control of diarrhea in-05 duced by modified polydextrose. It is believed thatthese two additional fiber sources will prove effec-tive in controlling polyol-induced diarrhea as well.
The laxation effects of various dietary fibers are set forth in Table V. The results obtained from this experiment which was conducted utilizing the same scientific method as was previously discussed to obtain the results listed in Table II, clearly shows that when the fiber sources are fed alone at the levels indicated they all significantly in-creased the fecal scores, or produce an acceptableand favorable laxation/bulking effect. The average fecal score results produced by feeding orange albedo flour, pineapple core or sugar beet pulp sources in the diet are clearly less than that of alpha cellulose ~fecal score of 1.15), and yet greater than that of the control diet (fecal score of 0) in this study.

Results in Table VI clearly show that with 20%

Addition of either 10 or 20% levels of orange albedo flour, sugar beet pulp or pineapple core samples are able to completely control (i.e., reduce or maintain average fecal scores to 2.0 or less) MPD-induced diarrhea.

Additionally, both orange albedo flour samples and soy fiber concentrate are able to completely control ~i.e., reduced fecal score to 2.0 or less) MPD-induced diarrhea.
11 ~ 7~0 Using the same scoring system employed to obtain the results of Tables II and III, tests were conducted to show the effect of several of the same dietary fibers in controlling diarrhea acutely 05 induced by orally dosing animals with 1.0 ml of an aqueous solution containing 28% by weight x-ylitol.
The results of this study is set forth in Table IV.

The following tests (See Tables V and VI) which utilize the same procedure and laxation fecal ~ ~7 ~0 scoring scale employed to obtain the results in Tables II and III have demonstrated the effective-ness of pineapple core bulking agent and sugar beet pulp bulking agent in the control of diarrhea in-05 duced by modified polydextrose. It is believed thatthese two additional fiber sources will prove effec-tive in controlling polyol-induced diarrhea as well.
The laxation effects of various dietary fibers are set forth in Table V. The results obtained from this experiment which was conducted utilizing the same scientific method as was previously discussed to obtain the results listed in Table II, clearly shows that when the fiber sources are fed alone at the levels indicated they all significantly in-creased the fecal scores, or produce an acceptableand favorable laxation/bulking effect. The average fecal score results produced by feeding orange albedo flour, pineapple core or sugar beet pulp sources in the diet are clearly less than that of alpha cellulose ~fecal score of 1.15), and yet greater than that of the control diet (fecal score of 0) in this study.

The treatment period was again 14 days and the fecal score value was arrived at by the same manner explained in Table III.
Results in Table VI clearly show that with 20%
MPD in the diet, all three fiber sources fed signi-ficantly reduce the severity of the average fecal scores. Addition of either 10 or 20% levels of orange albedo flour, sugar beet pulp or pineapple core samples are able to completely control (i.e., reduce or maintain average fecal scores to 2.0 or less) MPD-induced diarrhea.
