Embodiment 1

[0031] 1. Test raw materials

[0032] Big-leaf sweet basil is picked from Beijing Yunong High-quality Agricultural Products Planting Company, and transported to Beijing Agricultural College by cold chain. Relevant treatments and observations were carried out on the day of harvest, and large-leaf sweet basil was selected for testing, which was fresh, clean, uniform in size, and free from mechanical damage, diseases and insect pests.

[0038] 2. Test content:

[0039] Pack the prepared 2000, 3000, 4000AU / ml bifidobacteria bacteriocin into three beakers, and put the three beakers into three 1m 3 In the PP sealed box, take the blank as the control (CK). Respectively put 500g of fresh basil into four airtight boxes, and seal them. Store in cold storage (relative humidity 75%-85%, temperature (4±1)°C) for 12 hours, and then store about 20g of pretreated basi...

Embodiment 2

[0076] This embodiment is a preferred solution on the basis of Example 1. The raw materials used are all the same as in Example 1, and a fresh-keeping method for basil MAP packaging is provided. The fresh-keeping method includes selection, pretreatment, inflation, packaging and storage. Specific steps are as follows:

[0077] (1) Selection: select fresh, clean, uniform-sized, high-grade basil free from mechanical and pest damage;

[0078] (2) Pretreatment: Utilize the purified 3000AU / ml bifidobacteria bacteriocin to fumigate for 12 hours at a low temperature of 10°C to select the superior basil obtained through step (1);

[0079] (3) Inflating and packaging: use a gas proportional mixer to mix the gas, and the composition of the mixed gas is O 2 , CO 2 and N 2 Three kinds of gases; high-density polyethylene (HighDensity Polyethylene, HDPE) is selected as the packaging material, and the modified atmosphere packaging is carried out by vacuuming, inflating and heat sealing wit...

Abstract

The invention discloses a fresh-keeping method for ocimumbasilicum in MAP (Modified Atmosphere Packaging). The fresh-keeping method comprises steps of selecting, pretreating, aerating, packaging and warehousing, wherein a pretreatment mode in which extracted separated and purified 3,000 AU / ml Bifidobacterium bacteriocins are fumigated under low-temperature conditions is utilized; an HDPE (High Density Polyethylene) package is selected and inflated with three gases of O2, CO2 and N2, wherein volume ratios of the gases are as follows: 3% of O2, 15% of CO2 and 82% of N2. The fresh-keeping methodfor ocimumbasilicum in MAP provided by the invention has advantages of novel design, unique method, wide application and low production cost, solves key technology of short shelf life and perishable yellowing of ocimumbasilicum, extends an original shelf life of ocimumbasilicum from 4 days to 7 days, and has excellent practicability and popularization.

Description

technical field [0001] The invention belongs to the technical field of food processing and storage, in particular to a fresh-keeping method for basil MAP packaging. Background technique [0002] Basil (Ocimumbasilicum), also known as basil, vanilla, etc., is a plant of the genus Ocimum in the Labiatae family. Its tender stems and leaves are crisp and delicious, full of fragrance, and rich in nutrition. It is often used as spicy seasoning vegetables and seasonings. In addition to eating, basil can also treat bacterial infection and diarrhea, and has medicinal effects such as antifungal, antimutagenic, antibacterial, immune regulation and control of smooth muscle contraction, dispelling wind and heat, eliminating dampness and phlegm, promoting blood circulation and removing blood stasis; Used as a traditional Chinese medicine, it can be used for the treatment of skin itching, rash, pain and itching. [0003] At present, the research on basil at home and abroad mainly focuses ...
