Problems solved by technology

However, Pingpo seeds are very easy to germinate at room temperature, lose their edible value, and cause irreversible economic losses. How to adopt safe and effective methods to suppress the germination of Pingpo seeds under non-demand conditions is very critical, and it is also necessary for long-distance transportation and long-term maintenance. Storage plays an important guiding role

Embodiment 1

[0021] 1. Experimental method

[0022] 1. Seed pre-treatment: choose fresh, no pests, no rot, and mature apple seeds as raw materials for experiments.

[0023] 2. Screening of the concentration of edible coatings: 4 kinds of edible coatings were selected, namely: chitosan (CS), salicylic acid (SA), tea polyphenols (TP) and carboxymethyl cellulose ( CMC). They were grouped into groups CS, SA-CS, TP-CS, CMC-CS, and SA-TP-CS, and 20 grains of Pingpo seeds were soaked in each concentration gradient of these five groups of edible film-coating agents. The treatment time is 60min, and the total time of the combined coating is divided equally. The treated seeds are placed in an artificial climate incubator for cultivation (temperature 25°C, humidity 70%, light 3500LX)), and the germination of the seeds is observed after 4 days of cultivation. The specific results are shown in Table 1.

[0024] 3. Screening of optimal treatment time: fix the concentrations of CS, SA-CS, TP-CS, CMC-C...

Embodiment 2

[0050] 1. Seed pre-treatment: choose fresh, no pests, no rot, and mature apple seeds as raw materials for experiments.

[0051] 2. According to the film-forming combination with good effect screened out in embodiment 1: SA-CS, SA-TP-CS, adopt the mode of mixture treatment to carry out film-forming process to the seed of Pingpo seed.

[0052] (1) Prepare chitosan powder, salicylic acid, and tea polyphenol powder in advance, and weigh them well,

[0053] (2) Configure coating solution:

[0054] A: SA-CS combined coating solution, containing 0.20g / L SA, 15g / L CS;

[0055] B: 0.20g / L SA coating solution, 15g / L CS coating solution;

[0056] C: SA-TP-CS combined coating solution, containing 0.20g / L SA, 15g / L CS, 1.5g / L TP

[0057] D: 0.20g / L SA coating solution, 15g / L CS coating solution; 1.5g / L TP coating solution;

Abstract

The invention discloses a sterculia nobilis seed germination inhibiting method. Sterculia nobilis seeds are soaked in edible coating agent solution for 60-120min to inhibit seed germination. The edible coating agent solution comprises a coating agent A and a coating agent B, the coating agent A refers to chitosan, and the coating agent B is prepared from salicylic acid and / or tea polyphenol. The germination rate of the sterculia nobilis seeds treated according to the method is decreased remarkably, and the seeds can be stored for 20d at the room temperature. The method has advantages that effective inhibition of sterculia nobilis seed germination is realized so as to avoid economic loss, and fresh seeds are continuously supplied to the market, so that demands of consumers can be met whiledevelopment of the sterculia nobilis industry in China can be promoted, and a reference method is also provided for fresh keeping of other fruit products.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and relates to a method for inhibiting the germination of Pingpo seeds. Background technique [0002] Sterculia nobilis Smith (Sterculia nobilis Smith) is a plant of the genus Sterculia L. in the family Sterculiaceae, aliases: frequency po, water hyacinth fruit, nine-layer skin, cockscomb fruit, seven sister fruit, Pan'an fruit, rich and noble son, southern Fujian Formerly known as loquat fruit. Pingpo is native to South China, and likes strong light, high heat, and high humidity. It is widely distributed in Southeast Asia and South Asia. It has been cultivated for 1,000 years and is an important woody food crop. Pingpo seeds can be used as medicine, and can be fried together with candied dates and tangerine peel to cure bloody dysentery; the kernels are edible and suitable for food and vegetables. It has the effects of purging, killing insects, and improving eyesight. Folks in Guangd...
