Description
Technical Field
The invention relates to the field of fruit preservation, in particular to a method for preserving bananas based on a Cinnamomum kanehirae She Jinuo Lileaf extract as a preservative.
Background
Bananas are important cash crops in tropical and subtropical areas. The bananas are rich in carbohydrate, mineral substances, vitamins and other nutrient substances, and have the pharmacological effects of resisting oxidation, resisting cancer, reducing blood sugar, reducing blood pressure, treating diarrhea, relaxing bowel and the like, so that the bananas are deeply favored by a plurality of consumers. However, at normal temperature, the ripeness of the picked bananas is accelerated, so that the peel is brown, and the fruits are rotten. Too ripe bananas have poor taste and reduced nutrient content, and seriously affect the economic effect. At present, the fruit fresh-keeping method mainly comprises low-temperature storage, chemical fresh-keeping agent and chemical fresh-keeping agent combined low-temperature storage. However, these methods are costly and chemical preservatives pose a threat to the health of the consumer. Along with the importance of people on physical health and the improvement of food safety requirements, research and development of harmless and low-cost fruit preservative becomes a necessary trend. The development of a natural environment-friendly novel natural preservative is also becoming a popular research.
Cinnamomum camphora belongs to Lauraceae genus plant, and root, fruit and leaf can be used as medicine. The camphor leaf essential oil has unique faint scent, can be used for purifying air, can sterilize and kill parasites, can eliminate bacteria and inflammation on the surface of the skin when being coated on the skin, nourish the skin, and has the functions of regulating qi, relieving pain and promoting digestion. In addition, the Cinnamomum kanehirae Haw leaf water extract contains a large amount of polysaccharide components, has strong antioxidation capability, can effectively remove free radicals in the body, and delays the aging of the body. Noni belongs to the genus Morinda of the family Rubiaceae, and its fruits, roots, stems, leaves, flowers can be used as a medicine. Noni She Fuhan protein, essential amino acids, fat, trace elements, flavone and flavonoid glycoside, and has specific effects in treating inflammation, common cold, headache, fracture sprain, skin diseases, etc.
At present, no report is available on the utilization of the extract of the beautiful leaves of the Cinnamomum kanehirae Hayata She Jinuo as a preservative.

Detailed Description
The following examples are further illustrative of the invention and are not intended to be limiting thereof.
Example 1: preparation of Cinnamomum kanehirae (L.) Presl She Jinuo Liye extract
The preparation method of the Cinnamomum kanehirae Hayata She Jinuo Liye extract comprises the following steps:
s1, naturally air-dried Cinnamomum kanehirae She Jinuo beautiful leaves are cleaned by sterile water, dust on the surfaces of the dried leaves is removed, and then the Cinnamomum kanehirae She Jinuo beautiful leaves with clean surfaces are obtained;
s2, the sassafras She Jinuo beautiful leaves are prepared according to 5g:5g is put into a sterilized pulverizer, 100mL of sterile water is added for smashing, the mixed solution is put into a water bath kettle for incubation for 2 hours at 60 ℃ to obtain a Cinnamomum kanehirae over She Jinuo Liye solution;
S3, centrifuging the Cinnamomum kanehirae Hayata She Jinuo Liye solution at 6000rpm for 10min, collecting supernatant, and filtering the supernatant with 0.22 μm filter membrane to obtain sterile Cinnamomum kanehirae Hayata She Jinuo Liye extract.
Example 2: preparation of Cinnamomum camphora leaf extract
The preparation procedure of the Cinnamomum camphora leaf extract was substantially the same as in example 1, except that Cinnamomum camphora leaf was put into a sterilized pulverizer in an amount of 5g, and 100mL of sterilized water was added thereto for pulverization.
Example 3: preparation of noni leaf extract
The procedure for preparation of noni leaf extract was substantially the same as in example 1, except that noni leaf was put in 5g into a sterilized pulverizer, and 100mL of sterilized water was added to break up.
Example 4: fresh-keeping application
The preservative effect of the Cinnamomum kanehirae Haw She Jinuo Lileaf extract (prepared in example 1), cinnamomum kanehirae Haw leaf extract (prepared in example 2) and Morinda citrifolia leaf extract (prepared in example 3) as a preservative on bananas was compared. The method comprises the following specific steps:
S1, cleaning fresh bananas with sterile water, and drying surface moisture to obtain bananas with clean surfaces;
s2, placing the bananas with clean surfaces into sterile Cinnamomum kanehirae (or Cinnamomum kanehirae) She Jinuo Lileaf extract (or noni leaf extract) for soaking for 1min, naturally drying surface moisture, and placing into a fresh-keeping bag with sterile water as a reference;
S3, storing the bananas in an environment of 25 ℃. The browning index and the water loss rate of the bananas were measured every 2 days.
Peel browning index: according to the size of the browning area on the surface of the fruit, the classification is as follows: level 0: no browning exists; stage 1: the browning area is less than 5%;2 stages: 5-25% of browning area; 3 stages: the browning area is 25-50%; 4 stages: the browning area is more than 50%. The formula: browning index = Σ (number of brown color stage x number of fruits of the stage) ×100%/(number of total fruits x number of highest grades).
Water loss rate: the weight of each group of bananas was weighed and recorded on an electronic balance every 2 days. The formula: weight loss (%) = (m 0-m1)/m0 x 100%; where m 0 is the initial mass (g) before banana treatment and m 1 is the mass (g) after banana has been soaked and left for several days.
The results are shown in FIGS. 1-3.
As can be seen from fig. 1 and 3, banana peel is prone to browning at normal temperature. After storage for 8d at 25 ℃, the bananas treated by the control group (sterile water) and the Cinnamomum camphora leaf extract have full browning (browning index: 100%), which indicates that the Cinnamomum camphora leaf extract has no fresh-keeping effect on bananas. However, compared with the control group, the noni leaf extract (browning index: 91.67%) and the Cinnamomum kanehirae (Cinnamomum kanehirae) She Jinuo, the banana peel treated with the Cinnamomum kanehirae (Cinnamomum kanehirae) She Jinuo, the banana peel treated with the Cinnamomum kanehirae extract, the browning of which is most significantly reduced (browning index: 87.5%). The noni leaf extract and the Cinnamomum kanehirae sinensis She Jinuo Liye extract can delay the browning process of banana peel, and the Cinnamomum kanehirae sinensis She Jinuo Liye extract has the best preservation effect on bananas.
As can be seen from fig. 2, banana peel is prone to loss of water at normal temperature. When stored for 8d at 25 ℃, the banana water loss rates of the control group (sterile water), the Cinnamomum camphora leaf extract and the noni leaf extract are respectively 14.13, 15.28, 10.61 and 9.21%, which indicates that the treatment of the Cinnamomum camphora leaf extract does not reduce the banana water loss, but quickens the banana water loss. And the banana fruit treated by the noni leaf extract and the sassafras She Jinuo noni leaf extract has obviously reduced water loss, and the banana fruit treated by the noni leaf extract has the lowest water loss rate. This means that noni leaf extract and Cinnamomum kanehirae Hayata She Jinuo extract have water retention effect on banana peel, and noni leaf extract has best water retention effect on banana peel.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that the above-mentioned preferred embodiment should not be construed as limiting the invention, and the scope of the invention should be defined by the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
