Description

Formula and application of preservative and preservative composition containing ferulic acid hexyl ester

Technical Field

The invention belongs to the technical field of medicinal plant raw materials and food additives, and particularly relates to a formula and application of a preservative and preservative composition containing ferulic acid hexyl ester.

Background

Dendrobium officinale is a perennial herb of Dendrobium of Orchidaceae, commonly known as Heijiecao, is a traditional and famous and precious traditional Chinese medicinal material, is mainly distributed in Guangxi, Yunnan, Zhejiang and Fujian places and has the effects of tonifying stomach, promoting the production of body fluid, nourishing yin, clearing heat, improving human immunity, promoting gastrointestinal tract digestion, resisting aging and the like. The product has unique medicinal value and health promotion effect, and can be used as health promotion tonic. At present, the problems of putrefaction, color change, water loss, germination and the like of fresh dendrobium officinale are easily caused in the storage process due to the immature dendrobium officinale preservation technology. Therefore, the picked fresh dendrobium candidum strips are generally fried into spiral dendrobium candidum. Although the fried dendrobium candidum has longer shelf life than the fresh dendrobium candidum, part of nutrient components are lost in the frying process. Therefore, the market has great demand on the preservation method and the preservative for the fresh dendrobium officinale strips.

Ferulic acid is a phenolic acid commonly existing in cell walls of natural plants, and is widely applied to food and medicine industries due to good effects of oxidation resistance, antibiosis, cancer resistance and the like. However, the ferulic acid ester has poor solubility and unstable physicochemical properties, so the application of the ferulic acid ester in food is limited to a certain extent. Researches show that the ferulic acid ester derivative obtained by molecular modification not only embodies and maintains the biological characteristics of ferulic acid, but also has lower toxicity and stronger antibacterial and antioxidant properties. The existing research finds that the ferulic acid hexyl ester has strong bacteriostatic action and antioxidant action in a series of ferulic acid fatty acid esters with different carbon chain lengths, can effectively inhibit the growth of food-borne pathogenic bacteria, and slows down the hydrolysis and rancidity of grease.

The silver carp is popular with consumers due to its fast growth speed, high yield and rich nutrition. However, a huge amount of fish processing byproducts (fishbone, fish skin, fish scale) are formed each year, and the market potential is often neglected. In addition, improper disposal of these fish processing by-products is also a major factor in environmental pollution. The collagen is used as a structural protein, has very rich content in fish processing byproducts, and can be fully utilized to produce active peptide with high added value, thereby changing waste into valuable and reducing environmental pollution to a certain extent. A large number of studies show that compared with the action of antioxidase in human body, the protein hydrolysate has higher antioxidant activity, smaller molecular weight, simple structure and easier absorption, and has double effects of improving the antioxidant capacity of organism and supplementing nutrition when being taken into the body. The collagen antioxidant active peptide prepared from the silver carp scales can reduce environmental pollution to a certain extent, improve the market and potential value of fish processing byproducts, and has wide market prospect and positive practical significance.

The pullulan is extracellular polysaccharide secreted by aureobasidium pullulans, has the characteristics of edibility, no color or odor, no side effect on human bodies, good air tightness, plasticity, easy adhesion and the like, and is a novel multifunctional fresh-keeping material with high economic value and development potential. At present, more researchers research the application of the preservative in fruit and vegetable preservation, and the preservative is added into the preservative to be used as an edible preservative film to improve the quality of the fruit and vegetable and prolong the shelf life. However, no report has been found about the application of pullulan in the processing of medicinal plant raw materials as an edible preservative film.

The jasmine contains abundant flavone and flavonoid components, can remove free radicals, resist oxidation and inhibit food-borne pathogenic bacteria to a certain extent. The researches show that the jasmine flower extract also has the physiological functions of cancer prevention, cancer resistance, senility delay and the like. And the jasmine has light faint scent, and the adsorption and masking effects of the jasmine can be utilized to endow food with the fragrance of the jasmine, so that unpleasant smell of the jasmine is removed.
