Description

Manufacturing method for haw jelly containing no aluminium

The present invention relates to a kind of improvement of haw food jelly preparation method.

Fructus Crataegi comprehensive nutrition and enriching, according to the measurement data of Beijing food research institute, its crude fibre, ash content, calcium, phosphorus, iron, carotene equal size surpass fresh fruits such as apple, orange, pears, grape, jujube, banana, lichee.Ascorbic content is also very high.

Haw jelly has another name called capital cake or haw jelly, and it is a primary raw material with hawthorn (haw), and combines by a certain percentage with sugar, acid substance, forms the gel pulp, and haw jelly promptly utilizes this characteristic to produce.

Good haw jelly production method must make product possess edibility and nutritive value simultaneously.Requirement utilizes the gelatification of hawthorn pectin to form scarlet transparent haw jelly, and product has peculiar flavour, the quality exquisiteness, and mouthfeel is lubricious, and outward appearance is tempting.And keep the nutritional labeling of original hawthorn as much as possible.

It is a kind of hydrophilic colloid that Fructus Crataegi contains HM (pectin) pectin, the pectin micella is electronegative in general solution, when the pH value at 2.0-3.5, the content of dehydrating agent sugar reaches 50% when above, pectin can dewater, and because of the jelly of charge neutrality gelling gel attitude.

The principal element that influences pectin gel formation has: the pH value of slurries, the concentration of sugar, the content of temperature and pectin, hawthorn kind and character.It is generally acknowledged: pH content is at 2.0-3.5, and sugar content 50% contains the primary condition that pectin amount 0.8-1.2% could form pectin, sugar, sour combination.Require about 50 ℃ of mixture temperatures before the gelling, be cooled to room temperature (0 ℃-30 ℃) then and just can not have influence on gel strength.

Traditional haw jelly production method adds alum, anticorrisive agent and food coloring in hawthorn, white granulated sugar, heating was boiled 10-15 minute, stirs the back and places cooled and solidified after 24 hours.As everyone knows, the aluminium element in the alum (alum) is harmful, other coagulating agent or food coloring, as belong to chemical products, also be to differentiate cautiously whether it is harmless.The haw jelly preparation method that Chinese patent application 88103698.6 proposes does not add alum (alum) and any coagulating agent, processing technology thereof is improved, amount of water for example, the temperature and time of first and second time insulation storage slurry, sugaring amount, pH value or the like, all done suitable control, but still there is following problems in it on technology, that is: (1) hawthorn maturing process adopts high temperature to steam fruit, and high temperature destroys the pectic substance of hawthorn itself easily.Influence the degree of gelation of product, high temperature has destroyed the nutrition of product, and product is easy to air pollution greatly because of workshop temperature height, steam, and the energy of consumption is also more.(2) one of primary raw material in the existing preparation method, granulated sugar all uses the syrup through high-temperature digestion more than 100 ℃, shortcoming is: the color and luster that will have a strong impact on the haw jelly product after syrup temp surpasses 80 ℃, because syrup viscosity is bigger, loss during production in pipe conveying procedure is bigger, cause the serious waste of the raw material and the energy, syrup dissolving back viscosity is bigger in addition, also can carry in the operation by pipeline in process of production, make the match ratio of haw jelly product bigger error occur, directly influence the quality of product.(3) preparation method of existing haw jelly, in its production process, all required waters all are demineralized waters, facts have proved as all waters and all use demineralized water that not only the cost of equipment and product increases, and also some side effects can occur, for example after the water demineralization, artificial cause the loss of trace elements such as calcium, iron, zinc in the water quality, caused the waste of aspects such as equipment investment, personnel and the energy, the condition of chemical contamination when having increased water treatment.

The objective of the invention is to propose a kind of improved haw jelly containing no aluminium preparation method, emphasis be separate never adopt alum and other anticorrisive agent and food coloring after, the quality reduction of product, pectic substance is destroyed, thereby the crack, many places appears in hawthorn, and product is soft, be a bit darkish in color, mouthfeel such as sends out puckery at problem; It is big also will to solve simultaneously the equipment investment that exists in the aforementioned manufacturing process, secondary pollution, and nutrition reduces, and manufacturing cost improves, a problem such as manufacturing process complexity.The present invention proves through test of many times, high temperature steams the temperature of fruit up to more than 140 ℃, needs the time long, the pectic substance destructible, on PROCESS FOR TREATMENT, after using the alternative high temperature steaming of hot-water soak hawthorn fruit instead, can prevent the loss of pectic substance, further improve product hardness, and can remedy the degree of gelation deficiency of product in the existing haw jelly manufacture craft, problems such as high temperature destroys product nutrition, and steam causes secondary pollution greatly, and consumes energy is more.The improvement of this technology, to improving the quality of products, the degree of gelation of stable prod keeps the nutritive value of product itself, plays a part key.For under the prerequisite of not adding any natural colouring matter or chemical synthesis pigment, keeping the natural of haw jelly is color and luster, the technology that employing directly heats up to granulated sugar substitutes the even mix of hawthorn of high temperature syrup and process hot dipping slaking, also can solve the problem that exists in the conveying of high temperature syrup pipeline simultaneously.Evidence, all waters there is no need to use demineralized water in the process of producing product, under water hardness＜250mg/Lcao condition, can draw qualified product and better effects if aspect the original color of maintenance hawthorn.

Invention is achieved in that a kind of haw jelly containing no aluminium preparation method, with the hawthorn is raw material, through operations such as choosing fruit, rinsing, slaking, separation, insulation storage slurry, meterings, mix mix with granulated sugar through preheating, metering under predetermined pH value, carry out congealing after the aseptic packaging, drinking water is heated to 80-100 ℃, hawthorn was soaked in hot water 3-5 minute, granulated sugar is directly heated up, and the intensification temperature is 70-90 ℃, make granulated sugar reach thermal balance after, holding temperature is more than 30 ℃, and all processes that haw jelly containing no aluminium is made is all used drinking water.The granulated sugar of the direct intensification heat treated of process is 1 with the match ratio (weight ratio) of the hawthorn pulp of process hot-water soak: 1.1-1: 1.2, adjust the pH value with citric acid, and make the pH value between 3.1-3.5.After the aseptic packaging, leave standstill haw jelly is congealed naturally, indoor temperature is controlled at that the time is 15-20 hour between 18-25 ℃.

Process of the present invention makes the haw jelly product keep the original color of hawthorn.It is under the prerequisite of not adding alum and other food coloring, the fresh colour that keeps original hawthorn, kept the rate that retains of nutritions such as the contained amino acid of product, vitamin, calcium, iron, zinc, and can make existing haw jelly processing technology reduce the equipment input of 25-30%.

Fig. 2: haw jelly containing no aluminium has manufacture craft flow chart (according to CN88103698.6A) now.

Now further narrate embodiments of the invention in conjunction with the accompanying drawings.

With haw raw material, through selecting, remove cull fruit, select qualified hawthorn.Qualified hawthorn is pulled out after clean with the drinking water rinsing, dropped into through in the hot water of handling of heating, the hot water during input is 90 ℃, makes hawthorn soak in hot water 5 minutes, finishes curing step.In separation circuit, will eliminate inedible parts such as carpopodium, fruit stone, pericarp, calyx, after separation circuit is finished through the hawthorn of hot dipping slaking, pulp is incubated storage, 70 ℃ of storage temperatures, the time is 7 minutes, adjusts the pH value with citric acid and makes it equal 3.3.The sugaring operation is raw material with the white granulated sugar, remove impurity through screening, charge ratio (weight ratio) according to granulated sugar and pulp is 1: 1.1, the granulated sugar of pulp with the process preheating is measured in proportion, stirred 5 minutes in promptly pairs such as granulated sugar, pulp and sugar sweet-scented osmanthus material being mixed at that time of adjustment pH, temperature is 75 ℃ when mixing stirring, stirring, homogeneous, adjust pH carry out simultaneously, why adopt simultaneously and stir, homogeneous, it is too many for fear of intermediate link transferring the technology of pH value, causes heat to run off.Granulated sugar and pulp are being carried out homogeneous, before stirring, the adjust pH, adopt and in advance granulated sugar directly is warming up to 85 ℃, the product holding temperature is greater than 30 ℃, make granulated sugar directly carry out thermal balance, changed and traditional in pulp, added the white sugar that only sieves, or white granulated sugar adds the technology that water boils ripe syrup, make original color and luster of product maintenance hawthorn and bigger hardness.Pulp after stirring is carried out aseptic packaging, and the product after the packing is allowed to condition to cool off naturally under 20 ℃ of temperature and congeals, and 20 hours standing times, treats to number after product congeals vanning, warehouse-in.

It is to be noted: the hot dipping curing process characteristics of hawthorn are earlier drinking water to be boiled to 80-100 ℃, then hawthorn is dropped in the hot water and soaked 3-5 minute, the reason of doing like this is: vitamin content and heating-up temperature are close in the hawthorn after deliberation, in the hawthorn Vit C contents about 60 ℃ because of minimum point appears in oxidasic activity, along with the rising Vit C contents of heating-up temperature is destroyed less on the contrary; Simultaneously, in of short duration heat time heating time (as 5 to 10 minutes), ascorbic content reduces less, avoid the direct heating of hawthorn is boiled, and also be to avoid one of key measure that reduces nutrition.Facts have proved that the of short duration immersion of hot water also can reach the effect that makes hawthorn softening.

The present invention adopts the granulated sugar alternative syrup through high-temperature digestion more than 100 ℃ that directly heats up.Granulated sugar intensification temperature changes bitter as surpassing 100 ℃ of granulated sugar tastes, and temperature is too low, is difficult for fully mixing with pulp, directly heat up than the high-temperature digestion syrup, equipment is simple, can guarantee the original color and luster of hawthorn, for the match ratio of stable prod, solve the difficulty in the transportation, bigger meaning is also arranged.

Overall process at production is used drinking water, for producing haw jelly in batches, has more important value.
