Embodiment 1

[0044] The invention relates to iced fig wine, which is prepared by using frozen fig squeezed juice and whole hawthorn fruit as fermentation substrates. The quality characteristics of pressed fig juice and whole hawthorn fruit are shown in Table 2. According to table 2 data and formula (1), calculate the volume (A 1 ) and hawthorn whole fruit quality (B 2 ) ratio must be ≥17.64.

[0045] Table 2 The quality of fermentation raw materials

[0046]

[0047] Squeeze juice from figs A 1 =400L, hawthorn whole fruit B 2 =16kg prepares ice fig wine as fermentation substrate. The main steps are as follows:

[0048] 1) Quickly freeze fresh figs at -18°C until the fresh fruits are completely frozen.

[0049] 2) Frozen figs were quickly crushed and squeezed. During the crushing and squeezing process, the temperature of the berries was kept at -7° C. to obtain 400 L of squeezed fig juice, and the sugar content of the squeezed fig juice was controlled to 28.5° Brix.

[0063]

[0064] According to table 2 data and calculation formula (1), the volume (A 1 ) and the quality of hawthorn whole fruit (B 2 ) ratio must be ≥2.85. Identify Fig Pressed Juice A 1 =600L, hawthorn whole fruit B 2 =20kg prepares ice fig wine as fermentation substrate. The main steps are as follows:

[0065] 1) Quickly freeze fresh figs at -18°C until the fresh fruits are completely frozen.

[0066] 2) Frozen figs were quickly crushed and squeezed. During the crushing and squeezing process, the temperature of the berries was kept at -10° C. to obtain 600 L of squeezed fig juice, and the sugar content of the squeezed fig juice was controlled to 32.0° Brix.

Abstract

The invention relates to an ice fig wine and a brewing method thereof. The ice fig wine is prepared by taking fresh fig as a raw material and adding crushed and unbreakable whole hawthorn fruits to afig squeezed juice to be used as a fermentation auxiliary material. For the first time, the fig is used as the raw material for brewing ice wine; the fermentation process is completed by glycolysis ofnatural sugar, so the mellow property of the product is improved; the methanol content in the fermented wine can be effectively controlled without addition of pectinase, so the product quality can beimproved; the activity of fig protease can be passivated by a high temperature and short time method, so the microbial pollution is reduced; a closed pipeline heater can effectively reduce the fruitaroma loss and juice browning, and the non-biological stability of the fruit wine can be significantly improved; low temperature fermentation is beneficial to yeast aroma production, the leaching rateof nutrients and antioxidant ingredients in the hawthorn fruits is improved, and the quality of the ice wine is improved.

Description

technical field [0001] The invention relates to an iced fig wine and a brewing method thereof, aiming at enriching the types of fig fermented wine and broadening the way for deep processing of figs, belonging to the technical field of fermented food processing. Background technique [0002] Fig, also known as Wenxianguo, Mingmuguo, Yingriguo, etc.; its small flowers are hidden in the sac-shaped receptacle, which is a cryptocephalic inflorescence, so it is called "fig". Figs were first introduced into my country in the Tang Dynasty, and gradually became popular in the Yuan and Ming Dynasties. At present, my country's fig planting areas are mainly distributed in Xinjiang, Shandong, Jiangsu and other places, but the total area is less than one-thousandth of the apple planting area, and it is one of the fruit species with the smallest planting area in China. [0003] The edible part of mature figs is more than 90%. In addition to sugar, protein, crude fiber, fat and other nutri...
