Problems solved by technology

However, since fruits and vegetables are perishable and degenerate or shriveled (Vc is oxidized) at room temperature and lose their edible value, it is of great significance to extract natural Vc from fruits and vegetables to make functional products with high natural Vc content

example 1

[0015] Example 1: Soak 140 grams of oyster shells in 0.05M hydrochloric acid solution for 1 hour, then scrub to remove the silt and other adsorbents on the surface of the shells, wet crush them through a 60-mesh sieve, and then process them with tap water and dry them at 100°C. Calcium source shell powder 118 grams; pick 2 kg of apples, wash them, add 4 kg of water, crush them, add 1.2 kg of 95% alcohol immediately, stir and extract for 2 hours in the dark, filter, concentrate the filtrate to 2 liters under reduced pressure, and then filter The natural compound organic acid concentrate is obtained; in the three-port reactor connected to the decompression device, add 2 liters of the natural compound organic acid concentrate and 20 times the volume of distilled water, and 0.1 times the weight of the natural compound organic acid concentrate Calcium source shell powder , immediately pump and reduce pressure, stir, and heat to 45 ° C until the organic acid is completely reacted and...

example 3

[0017] Example 3: The steps and methods are the same as in Example 1 or Example 2. The shells are selected from clam shells or scallop shells or mussel shells or conch shells. The quality of the natural compound organic acid calcium products for fruits and vegetables is the same or similar to that of oyster shells.

Abstract

The invention aims to provide a novel method for synthesizing fruit and vegetable natural organic acid calcium with shells as a calcium source. The principle process includes the steps of shell pretreatment, natural compound organic acid extraction, synthesis, crystallization and washing; the method includes the steps that the shells are pretreated in the first place, calcium source shell powder is obtained, fruits and vegetables with a high content of organic acid (including ascorbic acid) are selected and crushed, then subjected to light-avoiding stirring and extracting for 1-2 hours with 15-25% of ethyl alcohol and filtered, filtrate is added into a three-opening reactor connected with a pressure reduction device after being subjected to pressure reduction and concentration, additionally distilled water which is 15-20 times volume of the filtrate and an excessive quantity of the calcium source shell powder are added, the mixture is subjected to air exhaust, pressure reduction and stirring immediately and heated to 45-60 DEG C till organic acid reacts completely, and suction filtration is conducted while the mixture is still hot to remove the excessive quantity of the calcium source shell powder; clear liquid obtained after suction filtration is conducted is subjected to pressure reduction and contraction, then 95% of ethyl alcohol is added, the mixture is placed in a refrigerator at the temperature of minus 20 DEG C for crystallization, the mixture is washed with absolute ethyl alcohol at the temperature of minus 20 DEG C, or the clear liquid obtained after suction filtration is conducted is frozen and dried, and a fruit and vegetable natural compound organic acid calcium product is obtained. The method is simple in technological process, and the shells do not need to be calcinated.

Description

technical field [0001] The invention relates to a method of using shellfish processing waste (clam shells, oyster shells, scallop shells, etc.) Synthesis method of natural organic acid calcium of fruits and vegetables for high-value utilization of processing waste. Background technique [0002] As the most abundant mineral element in the human body, calcium is not only an important component of bones and teeth, but also plays an important role in the physiological process of the body. Studies have shown that calcium deficiency can cause a series of calcium deficiency, especially for infants and the elderly. Therefore, reasonable calcium supplementation is of great significance to maintain human health. At present, the main components of calcium supplement products are calcium carbonate, calcium gluconate, calcium lactate and so on. [0003] China is the country with the largest scale of shellfish farming in the world, with more than 20 species of main cultured species inc...
