Abstract
The invention discloses a low-fat pectin extraction method which includes following steps: (1) washing peels or defective fruits as raw materials and crushing the raw materials to a size being less than 2 mm; (2) adding water by 3-5 times and rapidly heating the water to 60-80 DEG C for boiling the raw materials for 10 min; (2) adding sodium carbonate accounting for 2% by weight of the raw materials with stirring continuously; (3) increasing the temperature to 90 DEG C with temperature maintenance for 1.5 h; (4) filtering the boiled raw material and vacuum-evaporating a filtrate at 40-60 DEG C under a vacuum degree of 0.5 MPa to obtain a pectin crude product; (5) washing the pectin crude product in a 95% ethanol solution for 2-4 times and drying the pectin crude product at 50-60 DEG C to obtain a low-fat pectin product. The method not only achieves full-utilization of wasted defective fruits so that incoming of fruit farmers can be increased, but also can reduce environmental pollution.
Description
Technical field
The present invention relates to a kind of preparation method of foodstuff additive, be specifically related to a kind of low-fat pectin extracting method.
Background technology
Pectin is mainly used as jelling agent, thickening material, stablizer, suspension agent, emulsifying agent and flavouring synergistic agent etc. on food, and can be used for makeup, and to protection skin, prevent ultraviolet radiation, wound is treated in smelting, and beautifying face and moistering lotion all deposits certain effect.China's pectin resource is enriched, particularly Hills, and application area, extracts pectin from various pericarp and inferior fruit, not only makes the cull fruit discarded be fully utilized, and increases orchard worker's income, also can reduce environmental pollution.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of low-fat pectin extracting method easy and simple to handle newly.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of low-fat pectin extracting method, is characterized in: pericarp and inferior fruit are cleaned, be crushed to less than 2 millimeters, add 3-5 times of water and be heated to 60-80 DEG C rapidly, boiling 10 minutes, add the sodium carbonate of raw material weight 2%, continuous stirring, and temperature is risen to 90 DEG C, be incubated 1.5 hours.Filter, evaporated by filter vacuum, temperature 40-60 DEG C, vacuum tightness 0.5MPa, obtain pectin crude product, and dried with after washing with alcohol 2-4 time of 95% by crude product pectin, bake out temperature is 50-60 DEG C, is low-fat pectin product.
Compared with prior art, the inventive method not only makes the cull fruit discarded be fully utilized, and increases orchard worker's income, also can reduce environmental pollution.
Embodiment
Embodiment 1, a kind of low-fat pectin extracting method, pericarp and inferior fruit are cleaned, is crushed to less than 2 millimeters, get the raw material 10 kilograms crushed, add 40 kg water and be heated to rapidly 75 DEG C, boil 10 minutes, add raw material weight 0.5 kilogram of sodium carbonate, constantly stir, and temperature is risen to 90 DEG C, be incubated 1.5 hours.Filter, evaporated by filter vacuum, temperature 40-60 DEG C, vacuum tightness 0.5MPa, obtain pectin crude product, and dried with after washing with alcohol 2-4 time of 95% by crude product pectin, bake out temperature is 50-60 DEG C, and oven dry end pulverizing is low-fat pectin product.
Claims (7)
