Example Embodiment

[0060] Example 1

[0061] Unit

[0062] The first embodiment is a continuous process without adding water. It is carried out in accordance with the UF and NF parameters of system inlet pressure, discharge pressure, supply rate, and temperature shown in Table 1.

[0063] Such as figure 1 ,100lbs of skimmed milk 110 raw materials are provided to the manufacturing method of the present invention for processing. The original lactose content is 5.0% or 5 lbs. The raw materials are processed by UF112 using 900MWCO membrane to produce UF retentate 111 and UF permeate 113. The concentrated liquid 111 mainly contains large molecular weight complexes, such as fat, protein-like casein, whey, some non-protein nitrogen (NPN) substances, and various minerals combined with macromolecules. The filtrate 113 contains small molecular weight compounds that can pass through the filter membrane, such as lactose, minerals, some NPN substances, and water. Then, the UF filtrate is collected in ...

[0072] Example 2

[0073] Unit

[0074] Example 2 is a batch process without adding water. Referring to Figure 2, 700 lbs of skimmed milk 210 is provided to the manufacturing method of the present invention for processing.

[0075] The lactose content of the raw material is 4.8% or 33.6 lbs. The raw material is ultrafiltered 212 until 175 lbs of concentrated liquid (UFC1) 214 is obtained under the condition of a concentration factor of 4X. The 525 lbs of filtrate (UFP1) 216 was concentrated 3.5X with NF218. 375 lbs of filtrate (NFP1) 220 is combined with UF concentrate (UFC1) 214 to form 550 lb of liquid 222, which is then ultrafiltered 3X 224.

[0076] The 367 lbs of filtrate (UFP2) 226 nanometer filtered 9X 228 to produce 326 lbs of filtrate (NFP2) 230. Combine this filtrate with UFC232 to form 509 lb of liquid 234. This liquid was then ultrafiltered 3X 236 to produce 170 lbs of concentrated liquid (UDC3) 238 and 339 lbs of filtrate (UFP3) 240. The filtrate was then na...

[0080] Example 3

[0081] Unit

[0082] Example 3 is a batch process of UF / NF with water. reference image 3 , Provide 100 lbs of skimmed milk raw material 310 to the manufacturing method of the present invention for processing. The lactose content of the raw material is 5% or 5 lbs. The raw material was ultrafiltered 4X concentration 312 until 25 lbs of concentrated liquid (UFC1) 314 was obtained. 75 lb of filtrate (UFP1) 316 was obtained. By adding 50 lbs of deionized (DI) water at a rate equivalent to UF filtrate (UFP2) 220, 25 lbs of concentrated liquid (UFC1) 314 was diafiltered. After using all the water, the concentrated liquid (UFC2) 322 is still 25 lbs, while the filtrate (UFP2) 320 is 50 lbs.

[0083] Combine 40lbs in 75lbs UFP1 with 50lbs UFP 2320 to become 324. This liquid is nanofiltered 325 until 25 lbs of concentrated liquid (NFC1) 326 is obtained. The obtained filtrate (NFP1) 328 is 67.5 lbs. Next, 65 lbs of NFP1 was combined with 25 lbs of NFC2330 to for...

Abstract

A dairy product without lactose is prepared from milk through ultra-filtration to obtain a concentrated liquid A and a filtrate A, nano-filtering of said filtrate to obtain a concentrated liquid B and a filtrate B, and adding the concentrated liquid A to the filtrate B. It is suitable for the patients of diabetes and obesity.

Description

technical field [0001] The present invention of lactose-free dairy products and methods for their manufacture relates to the field of methods for removing carbohydrates from dairy products. More specifically, it is related to the process of removing lactose directly from dairy products, including whole milk, low-fat milk, skim milk, and milk powder. Background technique [0002] Milk is a product secreted by the mammary glands. It is a complex and nutritious product containing more than 100 substances, which can be classified into: protein, fat, lactose, and minerals. [0003] Lactose is the main carbohydrate in milk. Its concentration in milk averages about 4.8% (4.6-5.0%) by weight. [0004] Although ordinary milk is one of the most valuable and convenient nutrients for human beings, especially for newborns, there is a great demand for lactose-free dairy products in the market. There are mainly three groups of people in this consumer market: [0005] 1. People with lac...
