Method for extracting malt extract powder from barley malt

Abstract

The invention belongs to the production field of malt extract, and in particular relates to a method for extracting malt extract powder from barley malt. The method adopts the barley malt as a raw material, and is characterized by comprising the following steps of: crushing the barley malt, carry outing size mixing on the barley malt and de-ionized water, and saccharifying and inactivating size; screening inactivated feed liquor by a pressure curved sieve, and cleaning the screened feed liquor by de-ionized water, and performing centrifugal separation on the screened feed liquor to obtain clear liquid; and carrying out vacuum concentration on the clear liquid in a concentrating pan, and drying the concentrated clear liquid by atomizing drying agent to obtain the malt extract powder. The method provided by the invention has a simple process and a short production period; and the malt extract powder is light yellow or yellowish and slightly sweet, and has the functions of good carrier performance, high thickening performance, large tackiness, instant performance, easy moisture absorption and the like.

Description

(1) Technical field

[0001] The invention belongs to the field of malt essence production, in particular to a method for extracting malt essence powder from barley malt. (2) Background technology

[0002] Malt essence, that is, the nutritional essence of wheat, this part of the essence is mainly concentrated in the wheat germ. At present, most of the raw materials of malt extract used in the society refer to refined wheat flour, and a few refer to maltose produced after saccharifying rice with barley malt as a biocatalyst. The part of the malt extract referred to is the malt sugar component, and it is not the nutritional essence of wheat.

[0003] In recent years, the types of foods that use wheat germ have gradually increased, but up to now they still use wheat germ directly as an additive, and the treatment of wheat germ is also physical methods such as baking, crushing pulp, etc. The essence of the germ is further decomposed and purified, and the wheat germ powder pr...

Examples

Embodiment

[0016] Process flow of the present invention is as follows:

[0017] Barley malt→crushing→sieving→adding water to slurry→saccharification→sieving→centrifugal separation→vacuum concentration→spray drying→wheat extract powder.

[0018] The specific operation steps are:

[0019] (1) Weigh 120kg, sieve the barley malt and crush it into 4~6 pieces with a crusher, and set aside;

[0020] (2) Weigh 100kg of crushed barley malt, and use 400kg of deionized water for pulping;

[0021] (3) Saccharify the slurry after pulping: raise the temperature to 38 degrees and keep it for 1.5 hours; then raise the temperature of the feed liquid to 52 degrees and keep it for 1 hour; raise the temperature to 64 degrees and keep it for 0.5 hours, raise the temperature to 68 degrees and keep it for 1 hour, then raise the temperature Heat at 80°C for 10 minutes for inactivation;

[0022] (4) Sieve the saccharified and inactivated feed liquid with a pressure curved sieve, and clean the sieved material ...
