Description

Relevant application with the low acid beverages cross reference of supplemented with nutritional calcium sources

This is that proposed on September 29th, 1998 and the application No.09/162 common pending trial of the present invention, 864 part continuation application.

Technical field

The present invention relates to low acid beverages, this beverage nutritionally is to augment with the calcium of effective dose.More precisely, the present invention relates to water and fluid milk, they are with calcium fortified and don't influence unfriendly and their taste or quality.The product of these reinforcements has additional biological utilizable calcium source.

Background of invention

Osteoporosis, a species impoverishment treating bone diseases has realized that it is a kind of main public health problem in many countries.This is modal in the world skeletal diseases, and it causes significant burden to the mankind on the quality of life and medical expense.

The medical treatment authoritative sources has determined that the shortage of dietary calcium is the key factor that forms osteoporosis.Calcium is the basic comprising material of bone, and the needs of lot of documents explanation calcium in our meals every day have been arranged in medical science and science magazine.In addition, many governments and public health department be recommended in should comprise optimal dose in our meals calcium to reduce osteoporosis.

For many important physical factors, calcium is a kind of essential nutrient in our the whole life process.Have that 99% calcium is present in tooth and the bone in the fit body of report.So calcium is essential to the formation and the maintenance of bone and tooth.Remaining 1% calcium is present in the blood and soft tissue of health, and part is ionization.In its ionization form, calcium all is very important to the proper function of blood clotting and heart, N﹠M and permeability of the membrane etc.Modern scientific research proof calcium is played a role to preventing hypertension and colon cancer.If the quantity not sufficient of the calcium that obtains from dietary source will satisfy the metabolism needs of soft tissue with skeletal calcium.Therefore, when the intake of dietary calcium is not enough, with regard to the entail dangers to skeletal metabolism.In the case, have less sclerotin to gather in growth, and extract calcium from adult bone, meanwhile, the intensity of bone has reduced.These situations all tend to make the loose and thing followed fracture of humanoid osteogen.

Many places in the world, the intake of calcium is far below recommended amounts.Though the nutritionist has emphasized that it is important accepting the nutritional requirements of every day in meals,, the requirement that will reach calcium in conventional meals is difficult.Augmenting calcium in meals is a kind of method, and still, by augmenting, health can only absorb the sub-fraction of the calcium of absorption.Except by augmenting the intake that increases calcium, the absorption of calcium also can be by increasing with calcium fortified liquid or food.Is special needs with the absorption that increases calcium for mammal by edible calcium fortified fluid, because mammal must be taken in a large amount of fluids in order to survive.Consequently, calcium fortified fluid, the particularly calcium fortified aquatic product that contains that contains remarkable concentration calcium is highly effective to satisfying the every day nutritional need from the intake of calcium every day.

Unfortunately, run into many technical problems in the exploitation of calcium fortified fluid.More precisely, used calcium fortified fluid product in the past, its calcium concentration is low, produce and suspend or precipitation, have bad peculiar smell the process time of rectificating, and these peculiar smell are described to hardship, metallic taste, the quality chalk shape and that " mineral matter " etc. is bad or the combination of above these shortcomings.For example, insoluble calcium phosphate need be added in the product with the suspended substance form, but this can cause the negative variation of product quality and taste, also can form precipitation, and promptly solid particle comes out and deposits to the bottom of container from the liquid phase separation of suspended substance.In addition, the insoluble calcium source has lower bioavailability than soluble form.Though the inorganic salts of some calcium, the bicarbonate of calcium for example, chloride, sulfate and some phosphate, its solubility can add the calcium of suitable a large amount in water,, can produce bad taste like this.Former calcium fortified beverage has been carried out covering the measure of bad flavor or bad quality, these effort require to add for example sugar, materials such as artificial sweetener and flavouring agent.Be typically, these have increased the material of empty calory for the measure that solves calcium fortified technology barrier, artificial sweetener for example, and it can influence total health status of consumer.In a word, need calcium fortified beverage, it can provide calcium and total health that can not provide unessential material, these materials can influence the consumer effectively, and these beverages should be able to easily be produced and store until drinking.In addition, people are reluctant to drink the bad beverage of taste, therefore require calcium fortified beverage should have the receptible hobby character of people.

Calcium fortified water is valuable especially, because it can at room temperature deposit, can drink in a large number and don't can take in non-caloric substance, and concerning because not anti-lactose and can not can be used as fluid calcium source the consumer of milk drink.The relevant in the past example of producing the calcium fortified aquatic product of receptible hobby comprises as follows:

United States Patent (USP) 5,716,649 disclose the calcium content that is used to the to increase water method to every liter of 200-500 milligram, and this method is pent-up water and tin catalyst and a glass fibre material in the stainless steel blending tank.Heated this mixture 15 days, and slowly cooled off 135 days then to finish the method.

United States Patent (USP) 4,325,975 disclose a kind of drinking water goods, and this water does not contain sodium and potassium, and every liter of product contains 60 to 125 milligrams of calcium, and it contains the indispensable element strontium and the lithium of a spot of essential minerals magnesium and non-nutritive.

United States Patent (USP) 4,851,221 disclose that being applicable to boards augments the drinkable liquid of calcium, and it is mainly by calcium hydroxide, and calcium carbonate or calcium oxide and citric acid are formed.

United States Patent (USP) 5,232,709 disclose calcium fortified mixing chocolate powder, and this powder contains 0.05% malic acid calcium citrate, skimmed milk power, cocoa power, a small amount of food coloring, the sucrose of salt and other compound and 66.88%.

In each of these patents, the water of disclosed reinforcement or beverage all can not satisfy at least one the desired parameter in fluid calcium source.Therefore, obviously still need a kind of calcium fortified aquatic product that contains, it on enjoying is can be received, is easy to again simultaneously produce and is convenient to store.

As calcium fortified water, once developed in the past and used calcium fortified dairy products.Augment by the amount that in water and cow's milk, increases calcium, might make people be easier to satisfied nutritional need calcium.In addition, when having vitamin D and lactose, the absorption of calcium is best, and vitamin D and lactose all are present in the cow's milk.Usually these products are strengthened with the unstability that prevents lactoprotein with insoluble calcium phosphate and are condensed.As previously discussed, the insoluble calcium phosphate in cow's milk and other low acid beverages can cause the negative attributes of taste and quality, and the sedimentation that causes suspended substance in storage process.In addition, insoluble calcium phosphate and solubility calcium compare be absorbed by the body less.In addition on the one hand, add some highly soluble calcium salt and can destroy the ionic equilibrium of cow's milk with enriched milk, it causes the unstability of protein and forms precipitation.

United States Patent (USP) 4,840,814 disclose the method for making calcium fortified cow's milk, and this cow's milk solidifies boiling Shi Buhui.The method comprises sterilization and cooling cow's milk, adjusts with alkaline reagent more than the pH value to 6.7 of cow's milk, is added to calcium in the cow's milk with organic acid water dissolvable calcium salt forms then and reduces the pH of cow's milk.

The method that European patent 586016 A1 disclose calcium fortified milk powder and made this milk powder.The method comprises mixes cow's milk and calcium fortification system to form calcium fortified mixture, cools off this calcium fortified mixture to the temperature that can make lactose begin crystallization effectively, and this calcium fortified mixture again dewaters.

United States Patent (USP) 4,701,329 disclose calcium fortified and phosphor intensified cow's milk, and it provides minimum calcium source precipitation, acceptable local flavor and acceptable viscosity and mouthfeel.The cow's milk of this reinforcement contains and is no more than the calcium that the daily requirement amount is recommended by U.S. of 100%, it be before pasteurization with tricalcium orthophosphate, carragheen and guar gum are added to be made in the fresh milk.

Rasyid and Hansen be at magazine Food Hydrocolloids, Vol.4, and No.5, report claims to have prepared a kind of high calcium soya-bean milk in one piece of document of pp 415-422 (1991), wherein using glucose acid calcium is as the calcium source.This preparation also contains calcium sequestering agent (calgon) and calcium gluconae stabilizing agent.Calcium content can be compared with cow's milk in the soya-bean milk that report claims to obtain, and it also has satisfied heat endurance.

Low acid beverages among the present invention as water and cow's milk, is with calcium fortified.Prescription of the present invention provides more biological utilizable calcium source and good solubility, and taste and quality are not had harmful effect, and milk is had protein stability.In addition, this is calcium fortified, and to contain aquatic product be very easy production, and need not refrigeration and can Long-term Storage, fortified milk goods of the present invention can be used for comprising milk powder, hard cheese in any use milk product, cottage cheese, farmer cheese, pot-cheese, vichyssoise, baste, pudding, sour milk, ice cream and nutritious drink and milk shake etc., but do not place restrictions in these.These and other advantage of the present invention will be set forth hereinafter.
