Problems solved by technology

However, after the passion fruit is picked, due to the lack of nutrient supply, the quality of fruits and vegetables such as color, flavor, and texture deteriorates, and it is easy to soften, age, suffer from postharvest physiological diseases and be invaded by microorganisms, and eventually spoilage, which makes the quantity and quality of fruits and vegetables worse. Quality suffers a lot, and post-harvest preservation is an important way to reduce losses

Embodiment 1

[0031] Embodiment 1: a kind of nano-material formula and preparation method thereof for passion fruit fresh-keeping, in 100kg, nano-material is made up of following raw materials:

[0032] Pectin 1kg;

[0033] Nano titanium dioxide 0.05kg;

[0034] Nano silver powder 0.02kg;

[0035] The balance is nano-carbon dioxide bubble water.

[0036] The pectin is passion fruit pectin.

[0037] Its preparation method comprises the following steps:

[0038] S1, preprocessing

[0039] Prepare more fresh passion fruit, cut the peel into pieces, wash it with sterile water for 3 times, dry it in an oven at 60°C for 48 hours to obtain easily crushed peel material.

[0040] Grinding the dried peel material to prevent the peel material from agglomerating during the lifting process, passing through a 50-mesh sieve to obtain peel powder, and then storing the peel powder in a sealed container at room temperature for future use.

[0041] S2, the extraction of pectin

[0042] Using citric aci...

Embodiment 2

[0061] Embodiment 2: a kind of nano-material formula and preparation method thereof for passion fruit preservation, the difference with embodiment 1 is, in 100kg, nano-material is made up of following raw material:

[0062] Pectin 0.5kg;

Abstract

The invention discloses a formula and preparation method of a nanometer material for fresh keeping of passion fruits, and belongs to the technical field of fresh keeping of fruits and vegetables. Every 100kg of the nanometer material consists of the following raw materials: 0.5-2kg of pectin, 0.02-0.06 kg of nanometer titanium dioxide, 0.01-0.03 kg of nanometer silver powder, and the balance of nanometer carbon dioxide sparkling water. The preparation method of the nanometer material comprises the following steps: S1, performing pretreatment; S2, performing pectin extraction: performing pectinextraction on standby peel powder to obtain passion fruit pectin; and S3, preparing the nanometer material: adding nanometer titanium dioxide and the nanometer silver powder into the passion fruit pectin, performing nanometer airflow crushing and grinding treatment to obtain a nanometer pectin composite material, and dissolving the nanometer pectin composite material into the nanometer carbon dioxide sparkling water during fresh keeping of the passion fruits to obtain the nanometer material which has a good fresh keeping effect; The shelf life of the passion fruits can be prolonged, and the quality, the color and the appearance of the passion fruits are improved.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, more specifically, it relates to a nano-material formula for keeping passion fruit fresh and a preparation method thereof. Background technique [0002] Passion fruit is a herbaceous vine of the Passiflora family Passiflora. With the consumption of fresh fruit, passion fruit can be processed into various products such as juice, syrup, jam, ice cream, candy, jelly, frozen fruit, soft drink, dairy product, emulsifier, thickener, etc. However, after the passion fruit is picked, due to the lack of nutrient supply, the quality of fruits and vegetables such as color, flavor, and texture deteriorates, and it is easy to soften, age, suffer from postharvest physiological diseases and be invaded by microorganisms, and eventually spoilage, which makes the quantity and quality of fruits and vegetables worse. The quality suffers a great loss, and post-harvest preservation is an...
