A crystallized or granular product obtained by such a crystallization method.

A preparation method of a low-glycemic index (GI) rice includes: washing indica paddy rice to remove impurities, soaking the indica paddy rice in water to obtain first indica paddy rice, and after the soaking, subjecting the first indica paddy rice to an ultrasonic treatment in water with a first preset volume to obtain second indica paddy rice; after the ultrasonic treatment is completed, filtering out the second indica paddy rice, and cooking the second indica paddy rice in water with a second preset volume to obtain third indica paddy rice; placing the third indica paddy rice in a vacuum bag for sealing, and subjecting the third indica paddy rice in the vacuum bag to an ultra-high pressure treatment in an autoclave filled with water with a third preset volume to obtained fourth indica paddy rice; air-cooling the fourth indica paddy rice, and refrigerating the fourth indica paddy rice in a refrigerator to obtained fifth indica paddy rice; after the refrigerating is completed, oven-drying the fifth indica paddy rice in a blast air oven for 1 h, stopping blast, maintaining a temperature of the blast air oven unchanged, performing tempering treatment on the fifth indica paddy rice, and then oven-drying the fifth indica paddy rice until a moisture content of the fifth indica paddy rice is less than 16% to obtain sixth indica paddy rice; and shelling the sixth indica paddy rice to obtain the low-GI rice.

A system to treat spirits with sound, the system including a wooden barrel configured to hold the spirits, at least one speaker, the speaker being configured to play a repeated pattern of sound into the spirits inside the barrel, the repeated pattern of sound being configured to cause the spirits to move inside the barrel in at least one waveform at a determined harmonic point, and a playback device to control qualities of the repeated pattern of sound.

Methods and systems for reducing acrylamide concentration in heat-processed products, and products produced by such methods and systems are provided. The baked products may be sprayed with a riboflavin solution and then irradiated with a UV light source to initiate monomer reactions of acrylamide and reduce the concentration of the acrylamide in the baked product. In addition, riboflavin may be dissolved in heat-processed products, followed by irradiation of the riboflavin-containing heat-processed products with a UV light source to initiate monomer reactions of acrylamide and reduce the concentration of the acrylamide in the baked product.

In accordance with at least one aspect of this disclosure, an apparatus for preparing a beverage with an infused frequency includes, a vibration inducer. The vibration inducer includes a diaphragm configured to be placed in or proximate a liquid being bottled and a vibration generator operatively connected to the diaphragm to drive the diaphragm at a predetermined frequency to induce a measurable pressure pulsation in the fluid being bottled. The apparatus further includes a controller configured to receive an instruction of the predetermined frequency and cause the vibration generator to vibrate at the predetermined frequency. The predetermined frequency can be selected as a function of a desired healing effect of the beverage preparation, for example, the predetermined frequency can align with one of the seven main chakra frequencies.

A preparation method of a konjac granule includes the following steps: step 1: dissolving a konjac powder in hot water; step 2: subjecting a mixed solution obtained in step 1 to sterilization; step 3: conducting enzymatic hydrolysis at 50 C. to 70 C. for 2 h to 6 h; step 4: conducting enzymatic inactivation; step 5: conducting homogenization at 10 Mpa to 45 Mpa; step 6: adding a fully-dissolved sodium alginate solution and a flavor-modulating substance to a mixed solution obtained in step 5, and thoroughly mixing; and step 7: calcification and gelation: adding a calcium solution to a mixed solution obtained in step 6 for gelation to obtain the konjac granule.
