Problems solved by technology

[0010] However, chemically synthesized antioxidants have more or less harmful effects
For example, BHT has an odor and is carcinogenic to rats, and has been banned by some countries; the United States has removed BHA from the list of GRAS (generally recognized as safe) food additives; TBHQ is volatile at higher temperatures, and excessive Eating may have toxic effects on animal organisms, and may even cause cancer risk. Japan has banned the use of TBHQ in 2004

Embodiment 1

[0035] The jujube leaves of Jujube jujuba in Linxian County, Luliang, Shanxi are picked, dried, and crushed into jujube leaf meal.

[0036] Weigh 500g of jujube leaf coarse powder, add 5L of deionized water heated to 90°C, soak in heat for 10h, continue to reflux extraction at this temperature for 1h, let it stand, and separate the extract and solid residue.

[0037] Filter the extract with a hollow fiber ultrafiltration membrane with a molecular weight cut-off of less than 150,000, and collect the filtrate.

[0038] Add 5 L of deionized water to the solid residue, raise the temperature to 90° C. for reflux extraction for 1 h, and collect the filtrate in the same way.

[0039] Combine the two filtrates, keep the vacuum degree of -0.1~-0.08MPa on the rotary evaporator, and concentrate under reduced pressure to 50ml by distillation at 65°C while maintaining a slight boiling state, and prepare jujube leaves with a final concentration equivalent to about 10g of raw materials / ml E...

Embodiment 2

[0044] The jujube leaves of Xinjiang Junzao are picked, dried, and crushed into jujube leaf powder.

[0045] Weigh 500g of jujube leaf coarse powder, add 5L of deionized water to soak for 12h, heat to reflux temperature and extract for 2h, filter with fast filter paper, and collect the filtrate.

[0046] 5 L of deionized water was added to the solid residue, heated to reflux temperature for extraction for 2 h, and the filtrate was collected by rapid filter paper filtration.

[0047] Combine the 2 filtrates, centrifuge at a speed of 2000 rpm for 10 min in a centrifuge, take the supernatant, maintain a vacuum degree of -0.1 to -0.08 MPa on a rotary evaporator, concentrate under reduced pressure at 70 ° C to 50 ml, and prepare a final concentration of approximately It is the jujube leaf extract concentrate equivalent to 10g raw material / ml.

[0048] Weigh 500g of seabuckthorn leaf coarse powder, and prepare a seabuckthorn leaf extract concentrate with a final concentration appro...

Embodiment 3

[0051] Extract the jujube leaves of Cangzhou Jinsixiaozao in Hebei, dry them, and grind them into coarse powder of jujube leaves.

[0052] Weigh 500g of jujube leaf coarse powder, add 5L of deionized water to soak for 12h, extract in a microwave oven with a power of 300W for 30min, filter with fast filter paper, and collect the filtrate.

[0053] Add 5 L of deionized water to the solid residue, extract in a microwave oven at 300W for 30 min, filter through fast filter paper and collect the filtrate.

Abstract

The invention discloses a plant-based antioxidant composition. The plant-based antioxidant composition is obtained by mixing a jujube leaf extraction concentrated solution and a hippophae rhamnoides leaf extraction concentrated solution according to a volume ratio of (1-1.5): 1. After walnut kernels are soaked in the plant-based antioxidant composition after being diluted for anti-oxidation treatment, normal-temperature shelf life of the walnut kernels can be effectively prolonged to 12 months or above, rancidity and rancidity are not generated, and acid value index and peroxide value index both meet the national standard requirements. The plant-based antioxidant composition is prepared by extracting medicinal and edible plants, does not have any adverse effect when being normally used, can keep an original taste of walnut kernels, and belongs to a green antioxidant technology.

Description

technical field [0001] The invention belongs to the technical field of food processing and relates to a natural antioxidant substance derived from plants. The antioxidant substance of the invention is mainly used for antioxidant treatment of walnut kernels. Background technique [0002] Walnut, also known as walnut and Qiang peach, is a Juglandaceae plant, and is known as the world-renowned "four major dried fruits" together with almonds, cashew nuts, and hazelnuts. [0003] Walnuts are rich in nutrients, including a variety of plant polysaccharides, proteins, unsaturated fatty acids, and contain essential calcium, phosphorus, iron, magnesium, selenium and other trace elements and minerals, as well as carotene, nuclear yellow vitamins, vitamin B1, vitamin E and other vitamins. [0004] Among the many nuts, walnut kernel is the only nut rich in α-linolenic acid, and nearly 70% of its fatty acids are polyunsaturated fatty acids composed of linoleic acid and α-linolenic acid. ...
