Embodiment 1

[0036] Commercially available ganoderma lucidum fruit bodies were crushed through a 40-mesh sieve, and ganoderma lucidum was enzymatically hydrolyzed with cellulase (commercially available, SIGMA reagent, C1184, derived from Aspergillus niger), and the enzymatic hydrolysis conditions were changed to obtain an enzymatic hydrolysis solution. Centrifuge the enzymatic hydrolyzate at a speed of 2000r / min for 10min, and retain the supernatant. The soluble total sugar content of the enzymatic hydrolyzed supernatant of Ganoderma lucidum under different conditions was determined by sulfuric acid-phenol method, and the scavenging rate of DPPH free radicals by Ganoderma lucidum liquid indicated the antioxidant activity of Ganoderma lucidum hydrolyzate.

Embodiment 2

[0061] Commercially available ganoderma lucidum fruit bodies were crushed through a 40-mesh sieve, and ganoderma lucidum was enzymatically hydrolyzed with cellulase (commercially available, SIGMA reagent, C1184, derived from Aspergillus niger), and the enzymatic hydrolysis conditions were changed to obtain an enzymatic hydrolysis solution. Centrifuge the enzymatic hydrolyzate at a speed of 2000r / min for 10min, and retain the supernatant. The soluble total sugar content of the enzymatic hydrolyzed supernatant of Ganoderma lucidum under different conditions was determined by sulfuric acid-phenol method, and the scavenging rate of DPPH free radicals by Ganoderma lucidum liquid indicated the antioxidant activity of Ganoderma lucidum hydrolyzate.

Embodiment 3

[0065] After the commercially available ginkgo is peeled and germ removed, steamed and beaten, the amylase and pectinase compound enzymes are added to enzymatically hydrolyze under the conditions of different enzyme amounts (0.5%, 1%, 1.5%, 2%) , changing the conditions of enzymatic hydrolysis to obtain enzymatic hydrolysis solution. Centrifuge the enzymatic hydrolyzate at a speed of 2000r / min for 10min, and retain the supernatant. The soluble total sugar content of the ganoderma lucidum enzymatic hydrolysis supernatant was determined at 490 nm by the sulfuric acid-phenol method (see the description in Example 1 for the method).

Abstract

The invention provides a ginkgo fruit and ganoderma lucidum concentrated solution. The ginkgo fruit and ganoderma lucidum concentrated solution is prepared from raw materials in parts by weight as follows: 1-3 parts of a ginkgo fruit hydrolysate, 1-3 parts of a ganoderma lucidum hydrolysate and 0.5-2 parts of sugar acid taste regulatory substances. The invention also provides a preparation methodof the ginkgo fruit and ganoderma lucidum concentrated solution. The preparation method comprises the steps as follows: preparing a ganoderma lucidum sporocarp cellulase hydrolysate; pretreating ginkgo fruits; hydrolyzing the treated ginkgo fruits with amylase and pectinase; compounding the ganoderma lucidum hydrolysate and the ginkgo fruit hydrolysate; and performing vacuum concentration to obtain the ginkgo fruit and ganoderma lucidum concentrated solution. The ganoderma lucidum and the ginkgo fruits are matched and complementary in nutrients and functions, the healthcare function is enhanced, and on the other hand, the absorption and utilization rates of polysaccharides in the ginkgo fruits and cellulose substances in the ganoderma lucidum are increased. Meanwhile, triterpene substancesin the ganoderma lucidum and flavonoid substances in the ginkgo fruits have antibacterial and anti-oxidation functions, and the expiration date is prolonged in the absence of a preservative and an antioxidant.

Description

technical field [0001] The invention belongs to the field of food science, and specifically relates to a ginkgo ganoderma concentrate and a preparation method thereof. Background technique [0002] Tumors and cardiovascular diseases have always been the most serious chronic diseases that endanger human life and health. A variety of natural phytochemical components have biological activities such as anti-tumor, immune regulation, anti-oxidation, inhibition of bacteria, and increase of blood supply. Long-term consumption of natural foods containing functional ingredients can reduce the risk of chronic diseases. The benefits of natural foods are attributed to bioactive phytochemical components such as triterpenes, polysaccharides, proteins and peptides. [0003] Ganoderma lucidum is a fungus, and traditional Chinese medicine has long regarded it as a precious Chinese herbal medicine that nourishes the body and strengthens the body. The 2000 edition of "The Pharmacopoeia of t...
