Abstract

The invention discloses an egg yolk fruit preservative and a fresh-keeping method thereof, belonging to the technical field of fruit and vegetable preservation. The composition of the preservative includes an aqueous solution of sodium carboxymethyl cellulose and additives, and an aqueous solution of sodium carboxymethyl cellulose is used as Based on 100% by weight, the additive comprises the following raw materials by weight: 2.0-4.0% galangal extract, 0.08-0.12% marine biological lysozyme, 0.2-0.6% total flavonoids from sand mustard leaves, and 0.05-0.20% gallic acid. The fresh-keeping time of the fresh egg yolk fruit treated by the method of the invention is significantly prolonged, and the fresh fruit can be stored at room temperature for 20 days or more. The invention provides a fresh-keeping method for prolonging the storage time of the fresh fruit of egg yolk, greatly reduces economic loss, and continuously provides fresh fruit for the market, which can not only meet the needs of consumers, but also promote the development of the industrialization of egg nut in my country, and at the same time It also provides a reference method for the preservation of other fruit products.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping agent for egg yolk fruit and a fresh-keeping method thereof. Background technique [0002] Mayo (Lucuma nervosa A.DC), is a perennial evergreen fruit tree belonging to the genus Saucisaceae, and is also reported to be a semi-deciduous fruit tree. Egg yolk is also known as lion head fruit, egg fruit, peach, peach olive, because its pulp is less watery, loose and powdery, and the pulp resembles boiled egg yolk, so it is also named egg yolk fruit. Egg nut is native to the tropical regions of Cuba and South America, and is cultivated in all tropical regions of the world, including Hainan, Guangdong, Guangxi, Yunnan, Fujian and other places in my country. The egg yolk fruit tree is beautiful, the fruit shape is beautiful, and the nutrition is rich. In addition to fresh food, it can also be processed into jam, cream, beverage or fruit win...
