Embodiment 1

[0008] Example 1: After the production of fruit juice leftovers, apple peel residues were refrigerated at -18°C, the mature apple peel residues after refrigeration were extracted with 30% ethanol, and the extract was concentrated under reduced pressure to a small volume; purification: the concentrated solution was then used with a macroporous resin T2401 performs liquid phase adsorption separation, washes the concentrated solution with 0.1% organic acid, then washes the concentrated solution with deionized water, and then uses 20%, 40%, 60%, 80% ethanol solution in four times For elution, different eluted components are collected successively, the required components are concentrated under reduced pressure to a small volume, spray-dried to powder with a spray dryer or dried to powder under reduced pressure to obtain the extract—apple polyphenols.

Embodiment 2

[0009] Example 2: directly extract ripe apple pomace with 30% ethanol, concentrate the extract under reduced pressure to a small volume and then refrigerate at -18°C; the purification process is the same as in Example 1.

[0010] The detection of embodiment 1 and embodiment 2: use the high-performance liquid chromatograph to measure, although the spectrogram of the present invention and the spectrogram of former apple polyphenols have certain difference, but the peak shape of its component is the same. Using mature apple pomace, the yield of apple extract is 0.3%. And with apple vegetables and fruits, its apple extract yield is 0.5%. Although the yield of the extract is higher than that of the former, the latter uses immature apples and fruits and vegetables as raw materials, resulting in a large waste of apple resources. The former is the leftovers of the fruit juice factory, and the mature apple peel residue is used as a raw material to produce apple polyphenols, so that th...

Abstract

The present invention relates to the production of malic polyphenol as one polyphenol mixture with apple peel slag. Apple peel pomace is used as material in extracting malic polyphenol mixture through the technological processes of extraction, adsorption, separation, spray drying or decompression drying. The malic polyphenol mixture consists of catechin, epicatechin, phloretin and proanthocyanin,has several physiological activity and may be used in antioxidant, antimutagent and anomalism resisting medicine. Using apple peel pomace to replace apple in producing malic polyphenol can reduce production cost.

Description

Technical field: [0001] The invention belongs to a polyphenol mixture production process, in particular to a production process for extracting apple polyphenols with apple pomace. Background technique: [0002] Before the present invention, the raw material for producing apple polyphenols was immature apples and fruits and vegetables. Based on the presence of a large number of polyphenol compounds and their physiological activity in immature apples and fruits and vegetables, the production of apple polyphenols is applied in the fields of pharmacy and food chemical industry. Apple polyphenols are fruit polyphenol compositions obtained by squeezing and extracting immature apples and then purifying them, as active ingredients of antioxidants, antimutagenic agents, and antiallergic agents, substances that exist in plants as plant secondary metabolites. However, apples and fruits producing apple polyphenols have strong seasonality, short harvest period, easy oxidation, and unfav...
